From top stream to scholar

"The subject is very complicated, and the progress is very slow." Yu Wanzhou spread her hands and said, "I also want to go home and rest for a few more days, but there is no way."

"You don't know, my current progress has slowed down to the point where I'm about to collapse." Yu Wanzhou shook her head and sighed, "Forget it, Qi Yuan, go back first, I'll go back to the hotel to think about it. "

"Okay." After Qi Yuan left, Yu Wanzhou returned to the hotel and began to think about it.

Holding the manuscript paper, Yu Wanzhou read it for a long time and sighed.Headache, really too much headache.Now he can check the calculation, but the progress will be very slow, but he has no other way, so he has to work hard to check the calculation.

While writing on the draft paper with a pen, Jiang Yi sent him a text message——

[I'm going to Beijing on business tomorrow, are you free? 】

【Tomorrow... there should be nothing wrong】

[Okay, I will contact you tomorrow]

Yu Wanzhou smiled after putting down her phone, and then devoted herself to her calculations.

In the middle of the night, the lights were dimly on, and there were occasional sounds of cars outside.Yu Wanzhou put down her pen and rubbed the space between her brows.Looking at the scenery outside the window, opening the window, the wind in May is a little gentle, blowing on Yu Wanzhou's face, very comfortable.Yu Wanzhou just lay on the chair and looked out the window.

Life is still pretty good, but... this calculation really broke him down.

After washing up, Yu Wanzhou lay down directly to sleep.Tired, don't think so much.Getting up tomorrow is another day of headaches, so let's wash up and go to bed early.Continue to have a headache tomorrow.

Lin Wei is different from Yu Wanzhou. He has to review the students' graduation defense these days. Yu Wanzhou is waiting to go back to Princeton University with Lin Wei, so he still has a few days to spare.

Woke up the next day, took a shower, and finished breakfast.After watching Qi Yuan's thesis defense, he himself does not intend to go to Beijing University.But after thinking about it, he seemed to remember that Qi Yuan hadn't published a paper before, not even in N/S journals.

So she walked to Qi Yuan's dormitory downstairs like a walk, and called him.

"God Yu?" Qi Yuan was sorting out his thesis, and Yu Wanzhou said on the phone, "Do you know the format of the thesis?"

"Well, Professor Zhuang Ran showed me the format."

"After you finish writing, remember to email me and post it on arXiv, and submit it to Annals of Mathematics. Is there any problem?"

"No problem." Qi Yuan smiled, "No problem."

"Okay, I still want to tell you. If that's the case, there's no need. I'll go to the graduation defense." Yu Wanzhou hung up the phone, and before Qi Yuan could speak, Yu Wanzhou told him hang up.

He put down his phone, shook his head, and continued to do his own thing.

When I came to the academic lecture hall, Professor Zhuang Ran was not there today, but Senior Brother Lin Wei was sitting in the first row, asking questions to the students.

Yu Wanzhou sat next to Lin Wei, and Lin Wei handed Yu Wanzhou a copy of the thesis.

After reading the thesis for a while, after the students answered Lin Wei's questions, Yu Wanzhou immediately asked new questions.

The student was so anxious that he was sweating profusely. He never expected that he would be confronted by two bigwigs from Princeton University when he graduated.

Finally, after he finished explaining, Yu Wanzhou nodded, and Lin Wei said, "Very good, let's be next."

While the students were leaving, Lin Wei said with a smile, "Why is Junior Brother here?"

"Yo, brother, what you said is that I can't come?" Yu Wanzhou smiled, "I'm bored, let's take a look."

"Do you want to relive the feeling you had when you graduated with a PhD?"

"Maybe, let them also feel my happiness." Yu Wanzhou smiled.

Lin Wei smiled and mourned for the graduates behind.

Yu Wanzhou also smiled. Of course, this kind of thing can only be understood but not expressed in words.

Then the students who came in all walked out of the academic lecture hall in a daze, with 'who am I, where am I, and what am I going to do? '.Yu Wanzhou didn't have a hard line either. It is true that their papers had more or less problems. Yu Wanzhou picked some representative questions and asked them.

In the end, seeing the desperate eyes of these students, he thought it was a little funny.

Shaking his head, his phone vibrated after a while.Yu Wanzhou glanced at the phone, it was Jiang Yi who called him.

He said to Lin Wei next to him, "Brother, I'll answer the phone first."

Lin Wei nodded and said, "You go."

"I won't come over later, I will go back to the hotel to study the subject at night."

Lin Wei nodded and stopped talking.

After leaving the academic lecture hall, Yu Wanzhou pressed the answer button and said to Jiang Yi, "What? Brother Yi has arrived in the capital?"

"Well, I just finished my work, where are you?"

"It's at Beijing University, can you find it?"

"Yes, why not, I'll come to find you, just wait for a while." Jiang Yi said with a smile, "Xiaozhou hang up first, I'll be right over."

Yu Wanzhou hung up the phone and walked slowly towards the gate of Peking University.It is impossible for him and Jiang Yi to eat in the cafeteria of Beijing University, so naturally they have to eat outside.As for where to eat, that will be discussed later.

When he came to the gate of Beijing University, Yu Wanzhou happened to see Jiang Yi standing upright and talking to someone. He walked over and said to Jiang Yi, "Brother Yi?"

"Hey." Jiang Yi said to the people around him, "Okay, you go back first, I'll see when I come back by myself."

The man looked at Yu Wanzhou, nodded, and drove away.

"Who is this?"

"Colleague." Jiang Yi rubbed Yu Wanzhou's head and said, "What's wrong? Are you unhappy?"

"No." Yu Wanzhou shook her head, "What are we going to eat?"

"What do you want to eat?"

"I... can do it all." Yu Wanzhou thought for a while, "Brother Yi wants to eat anything."

"It's fine, I'm not picky eaters." Jiang Yi thought for a while, "Where do you live?"

"It's in the hotel next to Beijing University." Yu Wanzhou paused, "Brother Yi, do you want to go and have a look?"

"Let's go later, let's eat first. I'm hungry."

The two were walking on the road, and Jiang Yi suddenly asked, "What is Xiao Zhou doing at Beijing University these days?"

"Well, it's mainly about Qi Yuan's graduation defense. Just now, I showed some other students the graduation defense. They all seem to be quite uncomfortable."

"It must be that your question is too tricky."

"How can it be, aren't those all basic problems?"

"That's over."

"Why is it over?" Yu Wanzhou gave Jiang Yi an angry and funny look.

Only then did Jiang Yi say, "Your basic question and the basic question of students' understanding are not a basic question, so it's not over yet."

"You..." Yu Wanzhou gave Jiang Yi a vicious look and came to the restaurant.

After dinner, the two took a walk in Beijing University for a while.The main reason is that Jiang Yi listened to Yu Wanzhou's complaints that he was too tired and difficult to check the calculations, and his progress was too slow.

After a long time, Jiang Yi didn't speak, and just listened intently to Yu Wanzhou's complaints.

After Yu Wanzhou finished speaking, Jiang Yi raised his eyebrows and said to Yu Wanzhou, "Let me take you out to play, I have been to the capital many times."

"Okay." Yu Wanzhou felt that it didn't matter where she went, but who she went with.

After playing all afternoon, Jiang Yi said, "Now, are you happy?"

"En." Jiang Yi said with a smile, "After dinner, I'll take you home."

"Hey." Yu Wanzhou just remembered, "Aren't you here on a business trip?"

"It's okay, I have nothing to do today. When are you going back to Princeton University? I'll see if I can see you off." Jiang Yi pinched Yu Wanzhou's frown, "What's the matter, didn't you say you're not unhappy? Why are you still frowning?"

"Well, I'm thinking about when to go back to Princeton University." Yu Wanzhou thought for a while, "I don't know too well, maybe I should ask my seniors this question."

"Your brother?"

"Well, I'm going back to Princeton University with him. It's really inconvenient for me to be alone. Senior brother can drive, but I can't drive." Yu Wanzhou said embarrassedly, "I really can't learn, what should I do? , Brother Yi?"

"What else can I do?" Jiang Yi said with a smile, "Then don't learn, I can drive."

Jiang Yi looked around, "Would you like something to drink?"

"whatever."

Jiang Yi got up to go shopping, Yu Wanzhou looked at the scene of people coming and going next to him, and suddenly felt that life was still very real.

"Your water." Jiang Yi stretched out his hand, Yu Wanzhou took it, took a sip, and said, "It's too difficult for me, and I have to take the students to do the project together."

"Qi Yuan, didn't you say it's pretty good?"

"It's pretty good." Yu Wanzhou paused for a moment, "But thinking that he is about to encounter this subject, I guess he will be at a loss for a long time."

"What's the matter?" Jiang Yi sat beside Yu Wanzhou.

"It's hard." Yu Wanzhou said in a deep voice, "It's much more difficult than any subject I've studied before. It can be said that this is the most difficult subject I've ever been exposed to. It made me very collapsed at one point."

"It's okay. If you have something to say, you can call me." Jiang Yi thought for a while and said, "My mobile phone is on 24 hours a day. You are welcome to call and harass me at any time."

"En." Yu Wanzhou nodded, "Brother Yi, let's go have dinner."

After dinner, Jiang Yi sent Yu Wanzhou back to the hotel.Then he left, and Yu Wanzhou, who returned to the hotel, continued to work on his own project.

Originally, I didn't want to go out the next day, and continued to study this topic in the hotel.Unexpectedly, Jiang Yi ran to him again.He even doubted whether Jiang Yi was on a business trip in the capital or asked for leave to accompany him.

However, after playing with Jiang Yi for a day, Yu Wanzhou felt that she was indeed much more relaxed, and her mood was not as heavy as it was a few days ago.

When Jiang Yi sent Yu Wanzhou back to the hotel at night, Yu Wanzhou suddenly asked, "Brother Yi, do you want to sit up?"

Jiang Yi almost fell flat and fell to the ground.

"Who did you learn this from?"

"Can you be healthier?" Yu Wanzhou looked at Jiang Yi with disgust, "I just let you sit, what are you thinking?"

"Hey, shall I really go up and sit down?"

"En!" Yu Wanzhou and Jiang Yi came to the room, opened the door, Yu Wanzhou pointed to the room and said, "Sit whatever you want."
