Top academic

Chapter 172: Choose Beasts or Worse Than Beasts (This chapter contains a high amount of "may", please subscribe with caution!)
All we can say is that there is a reason why Yu Yanjiang became the deputy chief engineer of the moon landing program.

Not only is he stingy, he is also very decisive.

The next day, a special teacher was found to start classes with Qiao Yu. The content of the lectures was naturally about confidentiality.

The teacher's surname is Wen, and when he met Qiao Yu, he showed his extraordinary temperament. As expected, he is the teacher who taught him confidentiality knowledge. His name is unknown, and his unit is unknown...

When Qiao Yu asked about it during their first meeting, Teacher Wen smiled and said, "I'm a teacher who teaches you such unpopular things, why are you asking so many detailed questions? I can't help you with academic research either.

You don't have to remember me in the future. As long as you can do what I taught you, I will be very happy! I'm not trying to scare you. About two-thirds of the people I taught went into sewing machines. "

This sentence surprised Qiao Yu greatly. It seems that the proportion of accounting students operating sewing machines is not that high, right?

"No, Mr. Wen, is it because you didn't teach well, or is it because you taught a quick introduction to sewing machines?"

Teacher Wen was not angry, but laughed instead.

"Haha, there is no such thing as not teaching well. Before they go in, I will participate in the interrogation process. I will not do anything else. I will first list the things they have done, and then ask them if they still remember what I told them in what class on what date.

Guess what? Once they use my memory recovery number, they can remember a lot of things immediately. The effect is quite good, but it will be too late to regret it by then. So I suggest you study hard. Although you may not use it too much this time.

But considering your age and ability, you will only be in your thirties in ten or twenty years, and the things you can access will be different by then. What you are learning from me now will definitely benefit you for the rest of your life."

Qiao Yu thought for a moment and said, "Well, you teach confidentiality and can also participate in the interrogation of leakers. I think Mr. Wen can probably guess what department you work in."

"Okay, I'm just telling you that you guessed wrong! Well... to be honest, this is my first time taking a class with a kid as young as you. It does feel quite strange." Teacher Wen said, shaking his head.

Qiao Yu asked curiously, "Oh, then you must be a senior teacher, right? And you are the kind of senior teacher who doesn't often tell the truth, otherwise you wouldn't deliberately emphasize it like this when you tell the truth."

"Well, let's not waste time and start the class. Today I won't tell you about those cold regulations. Let's start with a few cases to talk about the gap between what is and what should be kept confidential.

By the way, let me add one more thing. In the next twenty days, we will have two classes every day, one in the morning and one in the afternoon. Before all the courses are completed, I will temporarily stay in Room 8, Building 302, Rongyuan Hotel.

If you have any questions, you can always ask me. Of course, you can also ask me over the phone. You must listen carefully and don't be distracted! After all, we have to take an exam, and the exam results are very important. "

……

In this way, the first class ended with many cases, which also gave Qiao Yu a clearer understanding of confidentiality.

It turns out that this criminal law is quite different. For example, there is a principle of modesty in criminal law, which states that when pursuing criminal responsibility, the intervention of state power should be limited as much as possible.

Therefore, for many criminal facts, all judicial organs must try their best to investigate the suspect's subjective intent, that is, the motive for the crime. This is very important.

If the crime is not intentional, the sentence will not be too high. But confidentiality is different. There is no need to consider the motive, only the result.

The severity of the sentence or punishment is related to the level and scope of the secrets leaked. Even if there is no subjective intent, or even no benefits received, the situation still needs to be resolved...

Of course, it could also be the first class. In order to attract Qiao Yu's attention to this course, Teacher Wen specifically talked about several special cases to scare people.

However, after studying for a few days, Qiao Yu still had some different feelings.

Before, he thought that Yu Yanjiang’s so-called confidentiality training was nothing more than a casual talk about the contract, emphasizing the importance of confidentiality.

He never expected that this course actually involved so much, far more than what he had imagined, and also included various technical knowledge.

For example, information security and network security, information confidentiality principles and management, various encryption technologies, including but not limited to security protocols and standards at different levels.

It even includes content such as military and intelligence, legal and ethical analysis, etc. The most exaggerated thing is that all these courses are taught by Teacher Wen alone.

He arranged classes just like in high school. Although he was the only teacher, he arranged different courses for each class, combined with various cases and cites a lot of evidence. It sounded very interesting, and Qiao Yu couldn't help but indulge in it...

Well, I can only say that there are talented people in every industry. There is no doubt that Mr. Wen is definitely a top-notch figure in the field of confidentiality, at least in Qiao Yu's opinion.

After all, he felt that he had some basic ability to distinguish. For example, there is actually a set of objective standards to judge whether a teacher's teaching is good or not.

Qiao Yu also began to believe that this teacher Wen had probably really taught many big guys, and it was no joke that he had been admitted two-thirds of the way. After all, he really talked about many incredible cases.

Qiao Yu began to sigh, he really had too little experience! He even felt like a frog in a well, all kinds of weird things could happen in this world.

Even the most amazing screenwriters can’t come up with such ideas, but they can actually happen in this real world.

For example, a dozen or twenty years ago, an ordinary person who had just been laid off happened to pass by a company that was relocating, so he walked in directly with a box of personal belongings and took away three inconspicuous mechanical hard drives.

Then he took it to a second-hand dealer to sell it, but found that the data could not be read normally. Then he sold it directly to a second-hand dealer at a price of ten yuan per piece as waste.

The business owner had some knowledge and knew that the hard drive was encrypted, so he put it on a professional forum for help.

Unexpectedly, there was a great person on the forum who helped him find a way to decrypt the hard drive. Then he found that there were encrypted files in the hard drive. After reading them, he found that they were confidential research data on a certain control system that was extremely advanced at the time...

After monitoring these data, the investigation work started immediately. From the top management unit, to the scientific research enterprise, to the thief, to the merchant who recycled second-hand computers and the masters on the forum, all were arrested...

In a small case involving 30 yuan, more than 30 people were sent to work on sewing machines. The company involved was not only fined, but also had its qualifications revoked, with losses conservatively estimated to be several hundred million yuan.

According to Mr. Wen, after the incident, everyone felt that it was so damn unfair, especially those who were sentenced to twenty years in prison, they all felt that they were the modern-day Dou E.

But after reviewing the incident, people were speechless. After all, if it was handled according to normal standards, this would never have happened.

If the second-hand dealers and the big names on the forum had any sense of awe, things wouldn't turn out like this.

So the instigator of the whole incident - the guy who rushed into another company and stole three hard drives on impulse because of layoffs, received the lightest sentence in this case, but still received three years in prison.

Coincidentally, this case took about three years from the time it was filed for investigation to the final trial, so the guy was released a few days after the verdict...

There are many similar cases. This is not the most bizarre one. In short, Qiao Yu and Teacher Wen have been getting along very happily these days.

Qiao Yu quite liked the feeling of gaining more strange knowledge every day. Most importantly, the cases introduced by Teacher Wen gave him a deeper understanding of the laws governing the operation of this world.

At least he can't do whatever he wants. There are too many surveillance cameras. The good news is that at this stage, with Chief Engineer Yu and his mentor protecting him, he won't be exposed to the kind of confidential or even top-secret data that could really put him in jail.

But as it happens, both sides thought it would be a good thing for him to be exposed to this kind of knowledge and to have a sense of awe.

……

In Teacher Wen’s class, a month has passed in 2026 and the winter vacation has arrived.

Although for Qiao Yu, life now is actually no different from before the holidays.

No, he was even busier than in the previous semester, because he had to attend classes every day, two classes a day, and each class lasted two hours.

On the afternoon of February 2, after finishing a two-hour lecture as usual, Teacher Wen said, "I have good news for you. You can have a day off tomorrow."

This surprised Qiao Yu. In fact, he didn't feel very tired after attending classes every day.

Although Chief Engineer Yu has sent over some data, everything is already on the right track and he has already contacted the Institute of Computing Technology.

He provided functions for processing data, and the person in charge was responsible for processing them in the way he provided.

At present, it is indeed as agreed before, all of which are non-sensitive data that can be found from public channels.

For example, the orbital parameters of the moon and the earth, celestial gravity, tidal force, gravity environment, communication positioning, etc.

The other side hopes to analyze these data and come up with something to verify many solutions.

For example, the optimal launch window for the lunar transfer orbit, the disturbance analysis of the Earth-Moon-Sun gravitational orbit, the optimal fuel allocation for multiple orbit corrections, and even the landing site selection, etc.

As we all know, both the Earth and the Moon are dynamic celestial bodies, and their relative positions are constantly changing.

Therefore, if you want to send people to the moon, you need precise orbital insertion and transfer windows, instead of just sending people out on a ship and then landing on the moon like in science fiction movies.

Of course, the moon landing project must have its own models for these things. Now let Qiao Yu process these data, most likely for some comparison purposes.

Anyway, the work at this stage is actually free. Before the confidentiality class is completed, it is basically voluntary work. So Qiao Yu has no pressure at all.

After finishing Mr. Wen’s class every day, he even had time to read a few articles on affine Weyl groups.

There was nothing he could do. Director Tian urged him every day to take other people's affairs to heart. Old Xue's work had already been going on, so Qiao Yu felt there was no need to rush him.

So I had to do some preparation work myself. During this period, he also supplemented his knowledge about algebraic groups, Lie algebra representations, and quantum field theory.

When he suddenly heard that he would be given a day off, his first feeling was that he was quite uncomfortable.

"Really? Teacher Wen, why do we need a holiday? It's only four hours a day. You're not tired of teaching me alone, and I'm not tired of learning either. Why do we need a holiday?

Besides, the Chinese New Year is only half a month away. Don’t you want to finish teaching me before the New Year so that you can spend the New Year peacefully? Why should we waste that time? "

Teacher Wen smiled and said, "I thought so too. But yesterday, the master of your faction specifically told me that it's your birthday tomorrow, so he asked me to give you a day off. As the younger generation, we still have to respect the opinions of this old man."

After hearing this, Qiao Yu was stunned. This period of time had been so busy that he even forgot his own birthday.

Yes, tomorrow is February 2rd, and he is one year older. I didn't expect that the old man still remembers...

"Ah... Actually, I always say that birthdays are nothing to celebrate. It's like a reminder that you're one year older and one year closer to leaving this world."

Qiao Yu sighed, then noticed that Teacher Wen's expression was a little off, so he quickly added: "Well, I didn't say you, Teacher Wen. You look quite young, at most in your forties. You still have plenty of youth to squander..."

"Okay, no need for your nonsense. I'm already 48 years old this year! It's impossible for me to squander my youth. But you can go and squander it tomorrow. That's it, let's go."

After saying that, Teacher Wen walked out of the classroom with his hands behind his back. Yes, this teacher never needed to bring books or lesson plans to class. Instead, he gave Qiao Yu more than ten books.

After Teacher Wen left, Qiao Yu sat quietly in the small classroom for a while.

In fact, this was his first birthday outside of Star City.

Qiao Yu still remembered that his birthday last year was on the sixth day of the Lunar New Year. He didn't remember it at all, but Xia Keke dragged him out for lunch at noon, and he took Qiao Xi out for dinner in the evening.

He received two birthday gifts, one from Xia Keke and one from his mother. Then he rushed to Beijing on the eighth day of the first lunar month.

Xia Keke gave him a pair of socks, which were said to be the kind of cotton socks that are effective in preventing odor. It was a small gift but a big thought. He happened to be wearing them.

Looking back now, I feel that things have changed. I didn't expect that the one who reminded him of his birthday this year would be Hua Qing's master.

This made Qiao Yu feel a little sad. After tomorrow, she would be seventeen years old. There was nothing wrong with being older, but the disadvantages were also obvious. She could only act cute for another year.

Once you turn 18, you become an adult. If you continue to act cute in front of a group of elderly people, you will appear childish and the effect will not be that good.

But then again, being treated as an adult does have its good side...

With all sorts of random thoughts in his mind, Qiao Yu took out his cell phone and called Qiao Xi.

Since the old man specifically found Teacher Wen to help him ask for leave, there must be some arrangements.

But to be honest, Qiao Yu really didn't like going outside at this time. The main reason was that he couldn't adapt to the wind in the capital.

Even on a sunny day, the temperature was only a few degrees, and the wind was strong in the capital. Qiao Yu felt that a gust of wind could blow his brain away.

Before coming to the capital, Qiao Yu thought that every time he saw a literary work describing the wind blowing on the face as if it were cut by a knife, it was too exaggerated. But after staying in the capital for a winter, he had a profound understanding of this.

This is not an exaggeration at all, it's fucking realistic!

There is no way. The winter in Xingcheng is actually cold, but it is a wet cold. The winter in Beijing is dry and cold. Even the wind is dry, as if it can crack the skin. It is still the most comfortable to stay in a warm room.

"Is get out of class over?" As soon as the phone was connected, Qiao Xi's lazy voice came into his ears.

"Well, get out of class is over! Teacher Wen just said that Master asked for a day off for me. Oh, I'm already one year older without realizing it."

"If you're itching to get your ass kicked, just tell me. If you have nothing to do today, come over. We'll go to Jiasuo for dinner tonight."

"No, my birthday is tomorrow. Why should I go to Jiasuo for dinner tonight? It's not customary to celebrate birthdays in advance!"

"Why are you talking so much nonsense? You'll know when you get here. I'm telling you in advance that there's a surprise."

After saying that, Qiao Xi hung up the phone...

surprise?

Qiao Yu knew very early on that everyone's understanding of surprise is actually different.

For example, something that Qiao Xi thinks is a surprise may very well be a shock to him.

My mother Qiao Yu knows very well that she doesn't like to play by the rules most of the time. Most of these are inherited from my grandfather...

To be honest, many of my grandfather's ideas were unorthodox back then, which is probably why Qiao Xi's ideas are also very different, and he seems to be the same now.

For example, what kind of mother would think about her child’s premature love every day?
Well, puppy love... go to Jia Suo to eat...

On the way to Qiao Xi's place, Qiao Yu suddenly had a thought about the possibility of a surprise...

So he braved the cold wind, took out his cell phone, opened WeChat, and opened Xia Keke's chat window.

"Student Keke, you came to Beijing but didn't tell me in advance. What were you thinking? Don't deny it. I'm telling you, the entire Huaqing is full of my spies!"

After sending the message, there was no reply for a long time. Qiao Yu simply sent a WeChat video call again, but unfortunately no one answered for a long time.

Forget it, it's too cold. Qiao Yu put the phone back in his pocket. At first he suspected that he might have made a wrong judgment...

However, thinking that Xia Keke might be with Qiao Xi, Qiao Yu felt that his judgment might be correct, and unconsciously, he quickened his pace.

……

Qiao Yu’s judgment was indeed correct.

In the warm two-bedroom, one-living room apartment, Xia Keke and Qiao Xi were sitting in front of the TV, watching a boring soap opera and chatting just like they did in Star City.

The main thing was that Xia Keke was talking and Qiao Xi was listening.

In fact, it has been like this since she was very young. Compared with Liu Lu and Lao Xia, Xia Keke prefers to share some little secrets unique to little girls with Qiao Xi.

This is probably related to the special nature of the Xia family's work. When they are free, Xia Keke has to go to school and do homework. They may not be at home on weekends.

When Xia Keke has her winter and summer vacations, they start to get busy again. This is why Xia Keke follows Qiao Yu around to play during every winter and summer vacation.

The two little ones were tired from playing during the day, and Xia Keke didn't want to go to their grandparents' house, so they just slept at Qiao's house.

There is no way. When parents are not around, the generation gap between children and the elderly is unfathomable.

So from this point of view, Qiao Xi, who has been unemployed since childhood, has spent more time with Xia Keke.

Even Qiao Yu's grandfather took Xia Keke and Qiao Yu out to play more often than the old Xia couple.

The phone vibrated. Xia Keke took out her phone and saw the message sent by Qiao Yu. Her originally excited face suddenly turned bitter.

"Oh, Auntie, does Qiao Yu know that it's me?"

"Oh? Let me see what he said?"

Qiao Xi reached out for the phone and took a look at it, then pouted and said, "Silly girl, is he cheating you?"

Then Qiao Yu sent a video request, and Qiao Xi threw the phone aside.

Xia Keke glanced at the ringing phone and subconsciously asked, "Are you scamming me?"

"Of course I followed the people arranged by Mr. Yuan to pick you up. How could I be so bored as to tell Qiao Yu? As for the fact that all of Huaqing is his spy, do you really believe it? He is just bragging!"

Qiao Xi said this with disdain, and then said earnestly: "You are all grown up now, you should have your own opinions. Don't listen to Qiao Yu's nonsense every day. In short, just do what we agreed before, and leave the rest to me."

"Oh." Xia Keke's mood suddenly became low and she responded sullenly.

"What's wrong? Are you unhappy because he cheated you?" Qiao Xi asked with a smile.

Xia Keke shook her head and said sadly, "No. I just feel that the gap between me and Qiao Yu is getting bigger and bigger. When he was in Class 13 in junior high school, I thought we would definitely be together in the future. But now I am becoming more and more uncertain."

Qiao Xi sat up straight for a rare moment and said, "Your idea is wrong. What do you mean by the gap is getting bigger and bigger? When it comes to emotional issues, what gap can there be?
And don't you know Qiao Yu? This guy is a typical person who is warm on the outside but cold on the inside. You see, he is very enthusiastic towards everyone, but he is not sincere at all. It's hard to get into this guy's heart!
At least you are definitely invincible in this area. Qiao Yu has been protecting you since you were young, he is really good to you. Not to mention that you have been fighting partners since you were young!

Just like you said, when you were a kid, Qiao Yu could help you realize whatever wish you had. Who else could have this treatment? Even now, I have never seen him really care about a few people.

So, don't lose heart. I'm counting on you to help me take care of that brat in the future! If I die first and there's no one to control him, I'm really afraid that he'll poke a hole in the sky."

Qiao Xi said the last sentence very seriously. She was really worried about this...

Principal Zhang, Tian Yanzhen, and Mr. Yuan, through their rich life experiences, have noticed that there may be some unsatisfactory aspects of Qiao Yu's character. But Qiao Xi is the one who knows Qiao Yu best.

It was as if she actually knew some of the things that Xia Keke had reconciled in front of her before, and she even knew them in more detail than Xia Keke.

Especially the time when Qiao Yu took revenge on his classmate’s father.

A stone with sharp edges was specially placed on the curb. If the people in charge of the implementation were not children, it would be impossible to follow Qiao Yu's plan completely. If the stone really hit the vital part, the person might be dead...

Qiao Xi still remembers asking Qiao Yu if he was not afraid of something bad happening. What if someone really died?
Qiao Yu replied nonchalantly, "That means he has done enough bad things that even God can't stand it anymore. What does it have to do with me?"

That day was the only time in her life that she beat Qiao Yu...

Yes, Qiao Yu had only been beaten that one time in her life. She was so tired from being beaten that day that her head began to throb and she couldn't hold on any longer, so she started crying.

But Qiao Xi was not sure how effective it would be. Even though from that day on, Qiao Yu began to become very enthusiastic towards everyone around him.

But Qiao Xi knew very well that this boy was just pretending, and if he did something like this again, he would hide it from her and not tell her. She also knew that this boy was not afraid of being beaten at all, but was simply afraid that she would have a headache again.

How should I put it? It is indeed good to have a son like Qiao Yu. But Qiao Yu's indifference to others is actually very scary. If you don't have a big heart, you will really worry and be afraid every day.

After all, with Qiao Yu's personality, he either doesn't cause trouble, but if he does, it's definitely a big deal. But Qiao Xi couldn't tell Xia Keke about these things.

"Well, Aunt Qiao, I understand." Xia Keke clenched her fists and said excitedly.

"That's right, you have to think about it this way. If two people want to be together, the most important thing is their feelings. There is no such thing as being compatible or not. Besides, if you want to be compatible, what does it mean to be compatible?
Family background, wealth, or wisdom? Do you think Qiao Yu would care about these things? He only cares about himself and the few people around him.

Just think about it, if Qiao Yu really meets a strong woman who can compare to him in the future, and the two of them are scheming against each other every day, how can they live?
Is it really a happy life if we live like the protagonist couple in the House of Cards? Oh..."

Qiao Xi said casually.

Xia Keke nodded ignorantly. She had never watched House of Cards and had no idea what life was like for the protagonist couple in the film.

However, after hearing what Qiao Xi said, she felt that it made sense, and her previous depression disappeared.

"I see. Then, Aunt Qiao, from now on, when we're together, I'll call you little mom, okay?"

Xia Keke asked, tilting her head.

"Okay."

Qiao Xi smiled, then reached out her hand and pinched the girl's collagen-filled face. It must be said that youth is good. It felt very smooth and tender...

Just then, there was a sudden noise outside the door, followed by a knock on the door.

"Keke, I know you're in there. Don't try to hide. Come and open the door! Really, you locked the door to give me a surprise. Is that necessary? Can't I guess?"

Qiao Xi winked at Xia Keke, but Xia Keke still stood up and went into the room, while Qiao Xi lazily went to open the door.

"Where's Xia Keke?"

Qiao Yu walked in, glanced at Qiao Xi, and then changed his shoes while muttering: "I told you not to play such childish games. Are you going to say that you are busy today, so you locked the door?"

"I don't think I said she didn't come. Coco is indeed here, but she went out again. She should be back for dinner."

Qiao Xi said without changing his expression.

Well, actually there was something strange, but Qiao Yu couldn't see it because Qiao Xi turned around and walked towards the sofa on his own.

"Oh? Where did she go? Would you let her go alone?" Qiao Yu asked half-doubtfully.

"She's going to buy you a birthday present. Why should I go? Should I help her pay for it?" Qiao Xi sat on the sofa and glanced at Qiao Yu.

"Oh, as soon as you mentioned the surprise, I guessed that Coco must have been tricked by you to come to the capital!"

Qiao Yu said casually, after all, this situation is indeed very likely. As for the fact that he sent a WeChat message but didn't get a reply, it was probably because he was shopping in the mall. It was common that the environment was too noisy and he couldn't hear the WeChat message.

Qiao Xi asked nonchalantly, "Just tell me whether you are surprised or not?"

"What can I say? I haven't seen Coco for a long time. Sometimes I really miss her. And high school is so inhumane. We are not allowed to bring cell phones. I can't contact her even if I want to."

Qiao Yu answered casually, then sat on the sofa. Seeing that the program on TV was boring, he was about to take the remote control to change the channel, but Qiao Xi grabbed the remote control first.

"Don't make trouble. I'm reading. If you feel bored waiting, go to my room and find a book to read."

Qiao Xi glared at Qiao Yu and spoke loudly.

"Watching too much of this kind of boring TV series will lower your intelligence! No wonder you didn't do well in your final exam!"

Qiao Yu complained but still stood up.

Rather than letting his brain be polluted by idiotic TV dramas, Qiao Yu still feels that it is more pleasant to pollute his brain with knowledge.

Of two evils, choose the lesser one.

He walked to Qiao Xi's door and just pushed it open as usual, when suddenly a little girl in a white sweater jumped in front of him with a firework in her hand!

"boom!"

"Surprise! Haha!"

As the colored paper slowly spread beautifully, it sprinkled all over Qiao Yu. However, what annoyed the young man was not this, but that he had guessed correctly but was still deceived by Qiao Xi...

Qiao Yu didn't doubt Xia Keke. He knew the girl he raised well and knew that her brain wasn't that useful.

"I told you not to be so childish..." Qiao Yu complained speechlessly, but he was not in a bad mood.

Moreover, after not seeing each other for more than half a year, Keke's eyebrows and eyes seem to have grown more open, and her gender characteristics are more obvious...

It feels more beautiful anyway.

Qiao Yu does not think that he is a superficial person. Compared with the face that is destined to age, he appreciates the interesting soul more.

But Qiao Yu also felt that before appreciating an interesting soul, one must first have a beautiful face to arouse his desire to explore.

Well, this shouldn't be a contradiction.

"Brother Qiao Yu, can you tell me first if you have any surprises?" Xia Keke asked cheerfully.

"Don't tell me, don't tell me... I'm so surprised! But can you tell me why you came to the capital first?"

As Qiao Yu answered, he casually brushed the colorful confetti on his head to the ground.

"Because my parents have to travel with the car again this year, Aunt Qiao invited me to Beijing to celebrate the New Year, and my mother happened to be on the car from Xingcheng to Beijing, so she just sent me over.

My mom said that I can play in Beijing until the sixth day of the New Year. Then I can go back with her car. Well, the main reason is that the school will start remedial classes on the eighth day of the New Year, otherwise I can play for a few more days. "

Xia Keke explained happily. It was obvious that she was very satisfied to be able to spend the Spring Festival in Beijing.

"Huh? Aunt Liu is on the high-speed train?" Qiao Yu asked.

"Yes, I took the high-speed train after training in the summer, and so did my dad. There are fewer and fewer green-skinned trains now."

"Is that so? That's it. Your father is such a heavy smoker, can he resist?"

"If I can't help it, I have to quit smoking. This way, I won't be scolded by my mom for smoking at home every day. Oh..."

"By the way, you are back alone, what about the elderly at home? How will they celebrate the Spring Festival?"

"It's just the right time to go back to my hometown! I guess it's because of this that my mother agreed to let me come to Beijing so easily."

Qiao Yu was very suspicious whether it was because of the decision to let Xia Keke come to Beijing to celebrate the New Year that the elderly on both sides were sent back to their hometown, or whether it was the other way around.

But this silly girl is so heartless and easy to coax, and he has gotten used to it.

"Okay, stop standing there and chatting. Come over here and sit down and talk."

Qiao Xi patted the sofa next to her. Having the two little ones beside her made her feel very satisfied. It was like she was back in the old house in Xingcheng, or like she was back in the time when Qiao Yu's grandfather was still alive.

She was still very young at that time...

……

The three of them had dinner at House A, and Qiao Yu paid with a credit card.

Xia Keke didn't care that Mr. Yuan couldn't come because of something. She came to see Qiao Xi anyway, and she felt more comfortable without anyone else around.

Although it was a bit self-deceptive, Keke enjoyed it. He had a satisfying meal, which was considered a welcome for Xia Keke.

After finishing the meal and walking to the entrance of the restaurant, Xia Keke said, "Qiao Yu, can you take me around the Huaqing campus? I didn't take a good look at the campus last time I came."

Qiao Yu glanced at Xia Keke and replied, "What's the good thing about it late at night? Aren't you afraid of the cold?"

"How can I be cold when I'm wearing such thick clothes?" Xia Keke said, patting her thick down jacket.

Qiao Yu hesitated a little (Note 1), and Qiao Xi behind him said, "Keke finally came here, what's wrong with you accompanying her around? Little girls are not afraid of the cold, so why are you afraid?"

"Oh." Qiao Yu finally agreed. Well, he compromised with Qiao Xi.

……

"Wow, Beijing is really cold!" Not long after the two young men walked out of the restaurant, Xia Keke started rubbing her hands.

"Humph, I told you it's cold outside. We haven't even reached Qiuzhai yet. Do you know how close Qiuzhai was to Jiasuo the last time you came? Only a few hundred meters!"

Qiao Yu laughed, then said cheerfully: "If you were like me, you would not be cold if you put your hands into your sleeves."

Xia Keke tilted her head and looked at Qiao Yu and asked, "Really? Then let me feel your hand to see if it's warm. Hey, it's really warm."

Qiao Yu found that he was careless and felt a little annoyed.

The girl's hands were indeed cold, but she held his hand and did not let go.

It's not that he doesn't like holding a girl's hand. It's mainly because he didn't see through the girl's intentions at the first time, which made him feel that his IQ has dropped a lot...

It was all Qiao Xi's fault for insisting on watching those IQ-reducing domestic romance TV series in the afternoon, causing his IQ to drop significantly.

Yes, it must be.

Just like this, the young couple, hand in hand, walked along Xichun Road in Huaqingli, passed Qiuzhai and Xichunyuan Restaurant, and came to the fork in the road on the second floor.

"Well, let me take you to Shuimu Huaqing. It's on the right." Qiao Yu said.

"Oh, what is it?"

"Yes, there is a small waterfall, a statue of Wen Yiduo and a small pond."

"Is it far?"

"Not far. I told you it's right next to you."

"But I want to go farther with you."

"Ahem, silly girl, I'm telling you, you'd better talk to me nicely, and stop using double entendres all the time!"

"Can you tell the pun?"

"Nonsense! I got full marks in Chinese! And it was the high school entrance exam!"

"Oh, then let's go to Shuimu Huaqing first, and then go somewhere far away?"

"I always feel like you're teasing me."

"Bah, I didn't!"

……

We arrived at the one-story wooden house of Shuimu Huaqing, took a look, and then walked around the small pond.

There were not many people here on winter nights during the winter vacation, and it was very quiet, but Xia Keke seemed very happy, jumping around. She just kept holding Qiao Yu's hand and refused to let go.

It was impossible for Qiao Yu to act more mature.

Of course, these are all forgivable. After all, he will be seventeen tomorrow, and Xia Keke next to him is more than two months younger than him. She will not be 4 until April 22, so it is understandable that she is more childish than him.

Although it is said that girls mature earlier than boys, that generally refers to the body, not the mind.

In short, this is how Qiao Yu understood it.

Just like that, on the eve of his seventeenth birthday, Qiao Yu took Xia Keke on a tour of Huaqing University...

There were many places he had never been to, and he accompanied Xia Keke to see them this time, such as the Jinchun Garden Relics next to Jinchun Road and the Observatory opposite the Wu Shunde Building...

With someone by my side, the winter night wind blowing on my face doesn’t seem to hurt that much…

Finally they arrived at the downstairs of the apartment building. It was already 11:30 at night. Before entering the building, Qiao Yu looked up and saw that Qiao Xi should still be in the living room with the lights on.

"Are you happy?"

Walking into the warm corridor, Qiao Yu asked casually, then withdrew his hand unnoticeably and patted the girl next to him on the shoulder.

Xia Keke didn't answer, but stopped, turned around, and stared at him with her big, bright eyes.

"Um... don't look at me like that. What are you planning?" Qiao Yu asked vigilantly.

"Have you ever kissed a girl?" Xia Keke suddenly asked.

Qiao Yu rolled his eyes and whispered, "I've been kissed by a girl!"

The scene of Xia Keke rushing into his room and standing on tiptoe to kiss her that day appeared in his mind.

Well, after not seeing her for half a year, the girl seems to have grown taller. Fortunately, he has grown taller too.

If you want to kiss her, you still have to stand on tiptoe.

"So there's no such thing? Can I let you kiss me once?"

The girl spoke softly, her breath sweet as orchid.

Qiao Yu felt a throbbing sensation. After all, he was only seventeen years old, and his shameful hormones were still secreted wildly by these words...

There is no other way. Between beasts and animals, it seems that I have to choose one in the middle.

……

At the same time, the Institute of Computing.

It was the middle of the night and most of the lights in the building were off.

Qu Junhao, the team leader responsible for connecting with Qiao Yu, knocked on Liu Zhaoyuan's office door with a stack of reports.

"Come in."

"Academician Liu, the preliminary analysis report is out. You see, the direction Qiao Yu gave is indeed very useful! The results we calculated in just one week are almost the same as the results we obtained in half a year.

By the way, we haven’t used so much and so complicated data. And it has been verified that the results obtained by his method for the next step of purification and calculation are likely to be more accurate than the results we calculated before. "

"Oh, let me see the report." Liu Zhaoyuan said immediately.

Qu Junhao quickly handed over the document in his hand.

Liu Zhaoyuan read it carefully without saying a word. Ten minutes passed like this. After he finished reading the entire report, he took off his glasses and raised his hand to pinch the bridge of his nose.

It seems that the Institute of Computing Technology will definitely pay for this fee...
