Chapter 73 That guy is really sick!
The finals scene at Xiaohu University headquarters.

Although there were no hot meals or dishes, considering that the students were still growing up, the organizing committee still prepared a lot of snacks such as cakes and placed them in the last row. You can take them anytime you need them.

Each person had a separate partition, and there were surveillance cameras with microphones in the examination room. The disciplines during the competition had also been explained long ago, so everyone behaved in an orderly manner.

The IQ of middle school students who can pass the preliminary round and be invited to the finals is definitely above average. At least it is impossible for them to fail to fully understand the key technical descriptions.

As the teacher often says: A loud drum does not need a heavy hammer.

But Qiao Yu never left his seat.

It wasn't that he wasn't hungry, or that he wanted to show off by submitting his paper early, but the answering system of Xiaolibaba's math competition always had some minor problems. He had encountered them in the preliminaries.

Firstly, the built-in latex cannot be modified, and the cursor position will jump around if you are not careful, which causes it to suddenly jump away when you want to edit the formula insertion position.

These are not big problems, but occasionally, if you stay on a certain question for too long, the system will automatically overwrite what you have written directly to the first question. And the first question of this exam is a big one.

In short, Qiao Yu felt that although the questions in this algebra and number theory track were not difficult, there were details everywhere.

If you relax a little, it's easy to break down your defenses.

So Qiao Yu planned to finish all the questions in one go and then submit them.

Just like that, at around 1:50 in the afternoon, after nearly five hours, Qiao Yu completed the last question, uploaded the answer, and then clicked the Submit button.

All done!

In fact, Qiao Yu had originally estimated that it would only take about four hours, but because of the detailed considerations on the first question, he thought about it too complicatedly and conducted classified discussions, which took a lot of extra time.

But it doesn’t matter.

Although I felt very hungry at one o'clock, after half an hour I felt too hungry. On the contrary, I feel pretty good now.

After submitting his answers, Qiao Yu stretched and then saw a staff member walking towards him. After a brief exchange, he followed the staff member out of the examination room.

It didn't cause any commotion.

Everyone was busy answering questions and at most looked up and glanced.

No one thought that Qiao Yu handed in the paper early. Someone who wanted to go to the toilet before was treated the same way.

……

"Are you going to your room to rest directly?" the staff member asked simply as you walked out of the examination room.

"I want to go see Teacher Lan." Qiao Yu replied.

"The teachers in charge should be waiting in the lounge now. I'll take you there." said the staff member, and then took Qiao Yu to the lounge where Langjie had stayed in the morning.

Seeing someone bringing a child over immediately attracted the attention of the teachers in the lounge, and countless eyes were focused on the door.

But to Qiao Yu's surprise, he saw many people, but not Ranger.

"Um...my teacher doesn't seem to be here." Qiao Yu said.

"Ah? Maybe he went to the toilet? How about I stay here with you for a while?" The staff in charge of invigilating the exam was stunned for a moment and answered subconsciously.

He was in charge of on-site supervision and had been in the examination room the entire time. Several colleagues went to the cafeteria to eat lunch separately, so he had no idea what was happening here.

Fortunately, footsteps were heard in the corridor at this time. Qiao Yu turned his head and saw Teacher Lan and another middle-aged man walking towards him.

"No need to bother, my teacher is here." Qiao Yu said.

"Professor Xue." The staff greeted him almost at the same time.

Qiao Yu suddenly became sensitive.

The main reason is that this surname has appeared many times in front of him in the past two days.

The ID who asked the question on the Algebraic Number Theory Treehouse Forum was Lao Xue. This ID sent him a private message saying that his real name was Xue Song, a professor at Yujiang University, and asked for his contact information. He also saw the profile of Professor Xue Song on the competition official website, a senior lecturer in the Hundred Talents Program at Yujiang University.

Considering that Yujiang University is right in Xiaozhou, Qiao Yu guessed who the person walking next to Lan Jie was without much thought.

It feels a little strange.

But Ranger solved his puzzle with just one sentence.

"You can see the process of answering the questions backstage. Professor Xue is very impressed with your performance in the finals. So, during lunch, he couldn't wait to ask me to find out more about you."

Qiao Yu smiled, he understood what Teacher Lan meant.

He didn't introduce himself first, but just said this sentence directly, which shows that the good guy guessed it. He knew the identity of Professor Xue next to him was Xue Song based on the staff's call just now.

The most important underlying meaning of this sentence is that it did not tell Professor Xue Song that he was the one who solved the equation on the Decimal House Forum.

Although this sentence is very quick-witted, Qiao Yu still feels that it is too rough and stiff.

After all, saying this right at the beginning would make people feel very strange.

If it were him, he would definitely introduce Professor Xue to his students in an orderly manner first.

He just said this right at the beginning, as if this junior high school student was very familiar with Professor Xue in private.

However, Qiao Yu knew that the good guy was too dull in dealing with people and society. In plain words, he had stayed in school for too long, and his thinking was too academic and not flexible enough.

Fortunately, Professor Xue should have similar problems and would not think too much about it.

So Qiao Yu immediately showed a shy smile and began to fill in the gaps.

"Hello, Professor Xue Song. I saw your name on the official website of the Xiaolibaba competition and went online to look up your resume. It's amazing."

Sure enough, Xue Song, who was a little confused at first, was immediately attracted by Qiao Yu's words and asked with a smile: "Oh? You still know me?"

"Yes, the fact that you were selected into Yujiang University's Hundred Talents Program at such a young age says it all. I've checked, and it's very difficult to be selected into Yujiang University's Hundred Talents Program!"

That’s right, this sentence doesn’t contain any useful information, it’s pure flattery.

On the one hand, Qiao Yu didn't mind at all to make the expert who might mark his paper happy; on the other hand, Qiao Yu was not clear about Xue Song's resume. Although he knew that praising his research results might be more effective, he didn't understand it and only had a general understanding.

You can't just start by saying that your understanding of the Diophantine equation is simply too profound, because that would sound like you are trying to cover up something fishy.

If Professor Xue gets interested and really forces him to chat for a while longer, it would be too easy to be exposed.

So it’s better to use your age advantage and just go for it.

He is only 15 years old and a junior high school math nerd, and his interest is in number theory. It is so damn reasonable for him to admire a young mathematics professor.

If Xue Song still had doubts, Qiao Yu felt that this professor was probably seriously lacking in confidence in his own ability.

Of course, this is obviously impossible.

A person who is not confident in himself would never say something like "I guarantee with my future mathematical life that this problem has 100% integer solution", even in a forum. In fact, Qiao Yu felt that he couldn't say such a thing without being proud enough.

Obviously Qiao Yu's analysis was absolutely correct.

How could Xue Song know that a little brat who was only fifteen and a half years old could have such a lot of tricks? Although the flattery was a bit blunt, even if it was his student who said this, he would not be happy about it.

But Qiao Yu is young. As we all know, how can a 15-year-old junior high school boy be so social?
Not to mention that he is a young genius who has already won his inner recognition.

For a moment I couldn't stop laughing.

"Haha, Teacher Lan, the kids in your Xingcheng are really good at talking. Qiao Yu, let's go to the room upstairs and chat together."

"Okay, Teacher Xue." Qiao Yu answered obediently.

Ranjie next to him couldn't help but roll his eyes.

Previously, Principal Zhang commented that Qiao Yu was able to please someone without making any noise and was particularly good at acting. He only had a vague impression of this in his mind, but now that this scene was vividly unfolded in front of him, he realized how versatile this guy Qiao Yu was.

When on the high-speed train, the little guy didn't take Professor Xue seriously at all.

When he said to suppress all these big guys, the desire in Qiao Yu's eyes was overflowing.

But now that he has met the real boss, not only is he not angry, he even starts to flatter him...

The staff member who brought Qiao Yu over happened to see Lang Jie rolling his eyes, but he obviously misunderstood. He just smiled implicitly and turned to walk towards the examination room.

It's not easy for these high school teachers...

Although Yujiang University is also very good, the prize money from Peking University and Tsinghua University is definitely higher than that from Yujiang University.

……

No matter what the people around him thought, Xue Song had already started chatting with Qiao Yu.

"Qiao Yu, we have finished the final test. How difficult do you think it is?"

"Professor Xue, the overall difficulty is moderate, but the questions are very clever. I was just in good shape today, otherwise I would have almost fallen into several traps. For example, in question 6, I almost overlooked that the effect of L on M might be ordinary.

If the action properties of L are really ignored, the subsequent derivation of the isomorphism of the module will definitely go wrong. In particular, if the details of the uniqueness condition are ignored, all subsequent reasoning may be wrong. "

Qiao Yu answered politely, showing the demeanor of a good student.

"Not bad, not bad. You are better than many people for noticing these small details. By the way, I heard from Teacher Lan that most of your knowledge of algebra is self-taught?"

"Well, I can't say that I learned everything by myself, right? Teacher Lan helped me a lot. And now that the Internet is so developed, there are many people who are my teachers, but I just haven't met them. The video tutorials on the video websites helped me a lot."

"It's already rare that you can reach your level by relying on the content on the Internet..."

Langjie followed beside them, listening to the fluent conversation between the adult and the child, and suddenly felt that he was quite redundant.

But he couldn't just turn around and leave, could he?

……

This one took three hours.

Yes, a professor from a famous Chinese university talked with a junior high school student for three full hours, and Ranger also listened for three full hours.

Qiao Yu showed no shyness in answering any of the topics, and he handled everything just right.

At least it seemed just right to Ranger.

The result was that when it was time for dinner, Xue Song directly made a phone call and then paid for the two of them to have a meal outside.

Just because Qiao Yu said that the food here is good, but it is not delicious without chili, he took a taxi to take the two of them to Xingnan Hunan Restaurant to let Qiao Yu eat hometown food. Really, Lan Jie felt that if he were Qiao Yu, he would definitely choose to confess to Xue Song during the meal that he was the one who solved the problem on the forum.

But Qiao Yu did not do that. He even declined the invitation implied by Professor Xue without leaving a trace.

Fortunately, the other party was not angry, and in the end both the host and the guests were happy.

After firmly declining Professor Xue's offer to send them back to Xiaohu University, Lan Jie got on the online taxi that Professor Xue had called for them. They drove all the way to the entrance of Xiaohu University. After getting off the taxi, Lan Jie couldn't help but ask, "Qiao Yu, aren't you afraid that Professor Xue will find out about your account number and it will be embarrassing?"

"Huh? Why is it embarrassing?" Qiao Yu asked back.

"I think Professor Xue is actually a nice person, right?" Ranjie asked back.

"Yeah, I think so too. So I provided him with enough emotional value today, isn't that good? Don't you think it would be awkward if I said those things today?" Qiao Yu blinked and said.

Langjie thought about it and suddenly felt that what Qiao Yu said was right.

"So, Mr. Lan, do you think it's better for everyone to be embarrassed face to face, or for everyone to suddenly learn about the news online and then feel a little embarrassed at first but forget about it after a while?"

Langjie thought it made a lot of sense. It seemed that he didn't think as thoroughly as Qiao Yu, and he subconsciously agreed with Qiao Yu's choice.

"That's right, it's quite embarrassing to talk about this in person."

"That's it. And Mr. Lan, we are competitors! You can't always think about competitors, right?"

"Ah? A competitor?"

"Didn't you say that one day in the future I would be able to defeat all those big guys? I take it seriously." Qiao Yu's tone sounded like a joke, but Ranger felt that the little guy was serious.

Sighing in his heart, Lang Jie also joked: "Before I came here, Principal Zhang repeatedly told me to pay more attention to you and teach you something good. But I feel that I can't teach you, but you will teach me bad things. Now I think everything you say makes sense."

"Haha, Teacher Lan, you are so humorous. How could you be taught badly? You are a good person!" Qiao Yu said seriously.

After hearing Qiao Yu's comment, Lan Jie felt mixed emotions. For a moment, he lost interest in talking.

In this way, the two of them walked silently to the vicinity of the guesthouse, and then found that there was also a pair of teachers and students walking near the guesthouse.

Originally, everyone was passing by each other, but the young man opposite suddenly stopped and called out, "Qiao Yu."

It was getting dark, and Qiao Yu stared at him carefully for a while before recognizing that it was Yu Wei, the relative who made the fat boy Yu Yongjun very unhappy.

"Is there something?" Qiao Yu asked casually.

"Can we chat?" the other party asked.

Qiao Yu glanced at Lan Jie beside him, and Lan Jie nodded to the teacher opposite as a greeting, then looked at him. The message in his eyes was very clear: Make your own decision.

While Qiao Yu was thinking about it, the teacher opposite him smiled and said, "Teacher Lan, how about letting the two children chat and we take a walk together?"

"Okay." Qiao Yu made the decision without waiting for Lang Jie to respond.

It just so happens that I’m a little full from the big meal just now, so taking a walk can help me digest the food.

There's no way. Xiaozhou's not-so-serious Hunan cuisine seems to taste better than Xingnan's authentic Hunan cuisine, and I accidentally ate too much.

Yu Wei walked a few steps quickly and came to Qiao Yu, who turned around and walked together. The two teachers followed behind them.

After walking a few steps, Qiao Yu knew why Yu Yongjun felt that Yu Wei was weird.

He kept his back straight while taking a walk, and his hands seemed a little stiff when he moved them. The most important thing was that it was clearly he who took the initiative to invite us to take a walk and chat together, but we had already walked for two minutes without even farting.

He would feel awkward if he changed. But Qiao Yu didn't care.

Anyway, his purpose was to take a walk, not to chat.

Just like that, two minutes later, maybe because he felt that Qiao Yu would not speak if he didn't speak first, he suddenly said, "How did you do on the test today?"

"It's okay. How about you?" Qiao Yu asked casually.

"I answered the first, third and fourth questions completely, and I think I should have answered all three questions correctly. I got the second question wrong, but I'm not sure if I can get the process points. I answered the first half of the fifth question, but I didn't have time to do the sixth question, and I probably wouldn't be able to do it even if I had time."

Qiao Yu was a little stunned.

He just answered and asked casually, but he didn't expect the other party to answer so seriously and methodically, with an overly sincere tone.

"That's pretty good. You got half of the six questions right, and you can definitely get some process points for the other questions, towards 50 points! If you're lucky, you might get an excellent prize." Qiao Yu commented casually.

"So yours is okay, what does that mean?" the person on the other end asked stiffly.

Qiao Yu suddenly laughed and asked, "If I say I can get full marks, would you believe me?"

"letter!"

This straightforward answer surprised Qiao Yu a little.

"Um……"

"You left the examination room at 1:53 and never came back. My coach saw that your teacher was asked to leave at noon, and then he and Professor Xue asked you to leave together around o'clock in the afternoon. This means that you must have done well in the exam." Yu Wei explained dryly.

"Oh, I see." Qiao Yu nodded, somewhat disinterested.

"My coach said that I have a high talent for math, the highest he has ever seen. Now it seems that he is just ignorant," Yu Wei added.

Qiao Yu felt that this sentence should be a compliment to him, but it still didn't sound very happy.

"You can't say that. Let me tell you a secret. I have a talent for mathematics... By the way, do you have a good relationship with your parents?"

The person next to him was silent for a moment before saying, "Very good."

Qiao Yu smiled and continued, "That's good, you can't learn from me. In fact, my mathematical talent is obtained through sacrifice. Every night before going to bed, I would pray to Guanyin Bodhisattva, willing to exchange my father's 30 years of life for my amazing talent, and then guess what? Some time ago, I suddenly got it, haha, so you can't catch up with me."

There was another silence. After a while, Yu Wei's voice finally reached Qiao Yu's ears: "This joke is not funny at all."

Qiao Yu happily raised his hand and patted Yu Wei on the shoulder, saying, "I'm not kidding, I really prayed!"

Although it was just an impromptu action, Qiao Yu could feel that when he touched the other person's shoulder, the guy's body became obviously stiffer and his brows even frowned.

Fortunately, Qiao Yu didn't care at all.

I've already agreed to accompany this guy for a walk and chat, so do I have to do everything he wants?
That's impossible. He is not this guy's father, so he must not spoil him.

The other party did not ask any more questions. The two walked for nearly a hundred meters in silence. Yu Wei suddenly asked, "Can you play Go?"

"I know a little, what's wrong?" Qiao Yu answered casually.

I do know a little bit, having played it with my grandfather when I was a child.

He learned Go, chess, and table tennis from his grandfather. Unfortunately, except for table tennis, his grandfather was not very proficient in other chess games. Qiao Yu was so good that he could defeat his grandfather in a crushing defeat when he was in the third grade.

So Qiao Yu actually didn’t know what his level was.

"There's a chance we can play next."

"Heh..." Qiao Yu wanted to refuse directly, but after seeing the luminous watch Yu Wei was wearing, he changed his mind: "I'm sorry, my time is very valuable. Go takes too long. But if you pay, I can consider it."

Yu Wei agreed without even thinking: "Okay, let's agree on how much a game of chess costs. If you can beat me, I'll pay."

"No, no, no, you misunderstood me. What I meant is that if you want me to play chess with you, you have to pay first. You can pay whether you win or not. Don't worry, as long as I take the money, I will definitely do my best to defeat you."

Yu Wei stopped again, took out his phone, and said in a flat tone, "Add WeChat."

"Hehe, we haven't decided how much the next game of chess will cost yet." Although he muttered to himself, Qiao Yu still took out his mobile phone. This guy was quite interesting. He didn't mind having more WeChat friends since he had added quite a few people in the past two days anyway.

Yu Yongjun and Xue Song don’t mind having one more.

Not to mention that Yu Wei seems to have the potential to become a financial sponsor.

Soon, both parties added each other on WeChat.

"How about it? It's still early today, do you want to play a game?" Qiao Yu asked again.

However, what he never expected was that Yu Wei directly replied: "You can play chess, but I won't pay you for it."

Qiao Yu curled his lips, a little disappointed.

Yu Wei added: "I am rich, but I am not stupid."

"Then why did you add me on WeChat?" Qiao Yu glared at the guy. Yu Yongjun was right. This guy was really weird and not cute at all.

"You inspire me, and one day I will surpass you, so I don't mind if you delete it." After saying that, Yu Wei stopped and said to Qiao Yu, "Goodbye."

The coach following behind him greeted Langjie with a smile, then took two quick steps and continued walking with Yu Wei.

Qiao Yu glanced at Lan Jie behind him, pointed at the pair who had already walked away, and said with certainty: "I suspect that guy is really sick!"

Ranjie walked over slowly and replied casually: "It's okay, you will meet again in November, then you can confirm whether he is really sick."

"Ok?"

"Yu Wei will definitely participate in this year's Mathematical Olympiad, and with his level, he will definitely have no problem making it to the national team, even if he doesn't make it."

"Heh... Are you sure that a guy who can only answer three out of six questions correctly can enter the national competition?" Qiao Yu took out his cell phone and decided to delete this inexplicable guy directly from WeChat.

"This question is very difficult! Oh, by the way, do you feel that his family should be very rich, maybe he is a wealthy man in Linhai." Ranger said.

Qiao Yu slowed down his movements and asked, "How did you figure that out?"

"If you don't have a fortune at home, don't even think about hiring a senior math coach from an international school to practice with you 24 hours a day. Mr. Chen is a famous figure in the math training industry, and has trained international gold medal students. In Linhai, most people who hire him as a tutor for two hours will charge a starting price of five figures."

Langjie said this specifically to let Qiao Yu know that being famous and being rich are the same thing.

But after hearing this, Qiao Yu simply put the phone back into his pocket.

Forget it. You can add thousands of people on WeChat, so one more won’t matter. People should be more generous and kind.

Qiao Yu still believes that good people will be rewarded.

Maybe this guy will suddenly go crazy one day and cry and beg for money to be given to him? We should give this patient a chance to find him.
