Chapter 196: The Four Golden Flowers of the Jiang Family and the Aunt and Nephew Discuss Numbers (4k)

Xu Qingshan actually didn't want to be stared at by so many people.

But with his appearance and height, he would attract a lot of attention wherever he went in the south, especially in Minyue.

When Ling Xiaole arrived at the night market, he was like a rabbit at the pasture, jumping around non-stop.

Tong Tong followed closely, holding Xu Qingshan's hand. Her attention was not on the stalls in the night market at all, and she didn't care what was there.

She didn't dare to stare at Xu Qingshan openly, but wherever her eyes went, there was always a hint of something on Xu Qingshan.

Ling Fei is a little different.

She was a little embarrassed, as if she didn't know what she should do. She just subconsciously wanted to get closer to Xu Qingshan, closer and closer.

This makes Xu Qingshan look like he is surrounded by women on both sides.

Some people who are envious and jealous passing by and seeing this would at least secretly spit on the decline of morals.

“This grilled squid looks delicious!”

"Auntie, I want to eat this fruit!"

"Shaved ice four-fruit soup! I want to drink it!"

Ling Xiaole was laughing in the front, and from time to time he turned back to ask Ling Fei for money to buy food. Ling Fei didn't say anything, but just stuffed the money into his pocket and continued to follow Xu Qingshan.

Tong Tong also noticed something was wrong.

"Here are some couple rogue rabbit marshmallows!"

"Brother, I want to eat that."

As soon as Ling Xiaole shouted in front, Tong Tong held Xu Qingshan's hand with one hand, gently tugged at the corner of Xu Qingshan's clothes with the other hand, and leaned against Xu Qingshan, and spoke softly.

"Okay, let's go buy it."

Xu Qingshan felt that Ling Fei beside him couldn't help but glance at the hands he and Tong Tong were holding.

But what can we do?

Xu Qingshan would not let go of Tong Tong's hand.

Ling Fei watched from behind as Xu Qingshan and Tong Tong stuck together and walked towards the stall, her eyes somewhat dim.

Even though she doesn't go out very often and doesn't interact with people very much, she is a romance novelist after all. How could she not notice the interactions and details between Xu Qingshan and Tong Tong?

"Brother, this is for you."

Tong Tong was quicker than Xu Qingshan. He paid the money and took two Rogue Rabbit marshmallows, just the right pair.

But when she saw Aunt Ling Fei following over and looking at them eagerly, she thought about it and asked the stall owner for another pair.

"Here, Aunt Ling, this is for you."

"Brother, you are so tall, it's okay to eat one more~"

Tong Tong blinked at Xu Qingshan, and Xu Qingshan understood what he meant.

"okay."

Ling Fei's originally confused look regained a lot of spirit after she took the marshmallow handed to her by Tong Tong.

In a popular restaurant not far from the night market, four women with extraordinary looks were sitting together through a huge glass.

Jiang Jingyi and Jiang Huanxi sat together. Jiang Lihua was still dressed elegantly, but next to her was a royal sister who looked not only young and beautiful, but also mature and intellectual.

"Aunt, how long can you stay this time?"

Jiang Jingyi, wearing a clean white dress, looked well-behaved and polite as she asked the intellectual lady sitting across from her.

Jiang Yuhua was originally concentrating on the steak on his plate. When he heard Jiang Jingyi's question, he looked up and thought about it.

"It's hard to say. I'll probably only stay in Lu Island for half a month. After that, I have to go to Huaqing to discuss their latest mathematics center. Do you two plan to go to the capital with me in advance?"

Jiang Yuhua looked at the two younger generations.

After returning from her vacation at Princeton, she was invited to visit and learn about the preparatory work for the Qiu Chengtong Center for Mathematical Sciences at Huaqing University, and was also invited to give a homecoming lecture at Huaqing.

"Meiningshi University is not far from Jingda University, so you two should go out more often."

Jiang Yuhua was cutting the steak with a knife, but it did not make any harsh sounds like ordinary people would.

"okay."

When this was mentioned, Jiang Jingyi lowered her head somewhat dejectedly, with a dim look in her eyes.

Although I got the opportunity to recruit students through self-recruitment, I also got extra points for self-recruitment.

Jiang Jingyi also tried her best in the last semester and did not even dare to talk to Xu Qingshan, but in the end, after adding extra points, she was still a few points away from the admission line of Peking University.

She was very unwilling, but helpless.

She was even a little jealous of Jiang Huanxi who was sitting opposite her.

The last time Jiang Jingyi went out to play after the college entrance examination, she found out that the relationship between Jiang Huanxi and Xu Qingshan was progressing faster than she had imagined.

And now, Jiang Huanxi can go to Peking University with Xu Qingshan again.

Thinking of this, Jiang Jingyi clenched her hands under the table.

"Where's Xiaoxi? Why isn't she talking? I heard you want to study mathematics and physics, so don't you want to talk to your aunt?"

"Yeah? Yeah, okay."

Jiang Huanxi had been staring out the window in a daze. He only came to his senses when he was interrupted by Jiang Yuhua and nodded repeatedly.

She felt as if she saw Xu Qingshan's back, but the distance was a bit far and she didn't dare to confirm it.

These days, my aunt Jiang Yuhua came back to Ludao from Princeton. My father was too busy with work to leave, and my mother had to accompany my father and take care of his daily life. Jiang Huanxi brought gifts and followed my aunt Jiang Lihua and Jiang Jingyi to Ludao to see my aunt.

After my aunt came back, she lived in my uncle Jiang Daohua's house.

Jiang Huanxi lives with her aunt, while Jiang Lihua and Jiang Jingyi live in a hotel near her uncle's house.

It’s not that Jiang Daohua’s house has no rooms, but Jiang Lihua enjoys this kind of life with thoughtful service.

"You don't ask questions. Do you want me, your aunt, to guess what you're thinking? You naughty boy~"

Seeing that Jiang Huanxi looked worried, Jiang Yuhua spoke again to attract the attention of his little niece.

“I’ve been reading about number theory lately.”

Jiang Huanxi came back to his senses and spoke in a serious tone.

"Number Theory?"

Jiang Yuhua asked with interest.

"What did you see? Did you read Euclid's proof of the infinity of prime numbers? Did you learn Gauss's quadratic reciprocity law? Or how to solve the continued fractions of Pell's equation?"

Jiang Yuhua chewed slowly and asked Jiang Huanxi.

She was indeed very interested in how far her second brother's well-behaved niece could go in the field of mathematics.

"I've finished reading it all. Now I'm reading the algebraic number theory part, but I just saw the expansion of prime ideals."

Talking about what I love.

Jiang Huanxi's eyes flickered and his answer was very calm and firm. He did not have the social phobia that would occasionally emerge when communicating with others.

Jiang Yuhua asked with some suspicion.

"Then let me test you a little."

"What should I use to replace the modular method and prime factorization method, which fail for equations such as x squared plus 2 equals y cubed?"

Jiang Jingyi: ???

Jiang Lihua: ???

What are these two people talking about?
However, science students who are obsessed with mathematics will not understand the outside world's misunderstanding. They will only immerse themselves in their own world of mathematics.

"Embed the integer ring into a larger ring, and then convert equations that have both addition and multiplication into product form in the larger ring, for example."

Jiang Huanxi stared at his aunt seriously and said.

As she spoke, she stopped eating pasta, took out the draft paper from her small bag, and wrote for Jiang Yuhua on the spot.

"There's something."

Jiang Yuhua looked at Jiang Huanxi's handwriting and said approvingly. Jiang Jingyi on the side was a little embarrassed. She was a liberal arts student and she really couldn't understand mathematics.

If it weren't for her low score in math in the college entrance examination, she wouldn't have been unable to get into Huazhong University of Science and Technology even with the extra points.

"Since you are so familiar with the theoretical basis, please explain the simple Diophantine approximation."

Jiang Yuhua and Jiang Huanxi have frequent interactions.

Soon, the piece of draft paper was filled with mathematical concepts and theorem proofs. To the mother and daughter next to them, it was simply a mystery.

"How about we eat first? Then we can go back and write after dinner?"

Jiang Lihua curled the corners of her mouth.

As a conceited business woman, she rarely encountered such occasions, and she could not get a word in.

"Oh, this draft paper is almost used up. Let's eat first."

Jiang Yuhua was stunned for a moment, looked at her sister's strange expression, and realized that she was now in an Internet celebrity restaurant, not at her workstation. This was Ludao, not Princeton.

She sometimes got used to sitting down and doing academic work anytime and anywhere.

Although the simple interaction with Jiang Huanxi tonight could not be considered academic, it was just a simple test of Jiang Huanxi's learning results in advanced mathematics.

"It shouldn't be too strenuous, right?"

Jiang Yuhua still looked at Jiang Huanxi.

"No, it's very interesting when I watch it and when I deduce it myself."

Jiang Huanxi said firmly.

She looked at Jiang Jingyi beside her and did not continue to say that she and Xu Qingshan were in regular contact for help and guidance.

"Xiaoyi applied for journalism, so she doesn't have to study math."

Jiang Yuhua glanced at Jiang Jingyi and said.

"Well, I'm just not good at math, so it's better not to learn it if I can."

Jiang Jingyi said.

After dinner, the four daughters of the Jiang family went to the night market for a stroll.

The main reason was that Jiang Yuhua wanted to go shopping. She basically had no social interaction while studying abroad. She just stayed in her student apartment, the library, and her workstation to study and research. Except for occasionally serving as a teaching assistant for her tutor and invigilating exams, she never even left Princeton.

She actually still misses the night market in her hometown.

"I think I could eat another cow!"

Although Jiang Yuhua looks like a queen, her personality is completely different from the other three Jiang family women present.

Perhaps it was because as a female academic researcher, she had no mood or interest in creating a fake persona for herself. After she studied mathematics, she became more innocent and wilder the more she studied.

"Eat, eat, eat, Yuhua. After dinner tonight, you should start to exercise moderation tomorrow. I will introduce you to a boy in a few days. He is also a PhD and looks good. I think you two will be a good match."

Jiang Lihua said helplessly as she looked at her younger sister's energetic figure.

In her opinion, when a woman reaches 26 or 27, she needs to start showing her charming side as a mature woman.

And she is also very worried about her younger sister's marriage.

"I don't want a blind date."

"It's not a blind date, it's just an acquaintance. Who knows if you have any connection in scientific research?"

"What did he study?"

"I'm not sure, it seems to be Ma Zhe's"

"Forget it. What does Marxism have to do with mathematics? I won't see you."

Jiang Yuhua left her sister and started watching the night market stalls by herself.

Jiang Huanxi didn't say a word and followed his aunt around. However, Jiang Yuhua's eyes were attracted by the various snacks on the stalls, while Jiang Huanxi was constantly searching in the crowd.

But Jiang Huanxi didn't find it.

Just as Jiang Huanxi took the grilled squid that her aunt forced upon her with a bit of disappointment, her cell phone lit up.

Jiang Huanxi's eyes also lit up and he immediately picked up the phone.

"You've come to Lu Island? I seemed to have seen you at the night market just now."

It’s news from Xu Qingshan.

Sure enough, the person he just saw was Xu Qingshan!
Jiang Huanxi's eyes seemed to be injected with new vitality, and she replied to the message excitedly.

"Yeah! I just saw you, but I can't find you anymore."

"I've already left. I just saw Jiang Jingyi and her mother there, so I was too embarrassed to go over and say hello."

Xu Qingshan's news cleared up Jiang Huanxi's confusion.

She looked up slightly at her aunt and Jiang Jingyi. They were indeed not easy characters for Xu Qingshan to get along with.

"How are you doing with number theory recently? I have a topic idea almost ready, and I'm waiting for you to join me. (deyi.jpg)"

"I have almost finished learning the parts you asked me to learn. My aunt came back from Princeton. Just now when we were having dinner, she tested me on algebra and number theory, and I answered all the questions."

Jiang Huanxi was typing away on her phone with both hands.

Although she is socially anxious and doesn't like talking to strangers in real life, it's different on the Internet!

And Xu Qingshan is not a stranger to Jiang Huanxi.

Yes. Good friend.

"Okay, then I'm about to start my project. You can help me then, and I'll assign you a second author. Since you're in Lu Island, let's find time to meet and talk about the project."

"All right!"

"Then tomorrow?"

"Ok!"

"See you tomorrow."

"See you tomorrow!"

Jiang Huanxi's eyes sparkled and her eyebrows were curved.

She was going to see Xu Qingshan again.

Although I didn't get the summer job, I was able to meet people.

"Sister."

Jiang Huanxi now lives with Jiang Yuhua, and they basically stay together during the day. Jiang Huanxi's uncle also lets Jiang Huanxi accompany Jiang Yuhua for walks everywhere.

If Jiang Huanxi wants to meet Xu Qingshan tomorrow, she has to ask Jiang Yuhua for leave and let her go shopping by herself tomorrow.

"Hmm? What's up?"

Jiang Yuhua stuffed food in his mouth and stared at Jiang Huanxi with wide eyes.

She was enjoying her meal.

Although she looks like a queen, she is actually inexplicably cute when doing things.

"I have an appointment with my classmates to discuss a math topic tomorrow. Can you go play by yourself tomorrow?"

Jiang Huanxi asked.

"Math project? Why don't you take me with you?"

Jiang Yuhua swallowed it. She was very curious about what kind of topic a child who was just about to go to college could write.

"Then should I ask him?"

Jiang Huanxi was stunned for a moment and asked hesitantly.

"Sure! Maybe I can even give you some free guidance."

Jiang Yuhua said nonchalantly.
