From top stream to scholar

"That's right." Yu Wanrong sat on the sofa and directed Jiang Xi to say, "Hurry up and cook, I'm exhausted today."

Jiang Xi finally went to the kitchen to cook the vegetables and meat he bought.When it comes to cooking, it means washing these vegetables and meat, cutting them up, and waiting for others to cook.He really can't cook, there is no way.

But it is still possible to cook white rice. After washing their hands, Wu Tong and Yu Wanrong went to cook. Several old people were teasing Yu Chuwei, and it was obvious that the old people really liked Yu Chuwei.Yu Wanzhou went back to his room to get busy with his own affairs, he still had a lot of calculations waiting for him.But there is not so much time to chat.

Yu Wanzhou was very happy doing math guesses inside, and Jiang Yi didn't know how long he had been busy outside. When he returned to the room, Yu Wanzhou ignored Jiang Yi.He was doing his own thing, then Jiang Yi lay on the bed and sighed.

"What? I was forced to ask when did I get my wife again?" Yu Wanzhou knew what was going to happen without even thinking about it.

Jiang Yi smiled awkwardly, "It's true, I'm tired of being asked all the time when I'm going to marry a wife."

"Then why don't you find one?"

"Look, where can I look for it? The Northwest Airlines base? The people there are either married or in love. I haven't reached this point yet."

"That's right, then you should get in touch more, don't you have a blind date meeting or something?"

"Northwest Aerospace Base is a secret base anyway, and it's even a blind date, you think too much."

"Then you will be an older single young man." Yu Wanzhou said jokingly, "You are not like me. I am still young in the United States, and my parents won't talk about it. When I grow up, I will go directly to the Northwest Space Base In such a research institute, they will never be able to talk about me. I think you will be miserable!"

"Let's talk about the future." Jiang Yi sighed, "I don't think about these things now, but listening to them is annoying."

Yu Wanzhou smiled and didn't speak.

"I said, you're still laughing, you're happy to see me suffer, aren't you?" Jiang Yi walked up to Yu Wanzhou and rubbed Yu Wanzhou's head vigorously.

"Hey." Yu Wanzhou responded, "I'm not happy, am I sympathizing with you? Why can't you be so kind?"

"Okay, you still know how to sympathize with me." Jiang Yi withdrew his hand, "Are you still doing your research? How is your research going? I've seen this for days. Do you think you won't be bored while doing research? "

"Boring?" Yu Wanzhou froze for a moment, then looked at Jiang Yi in astonishment, "Boring, how can it be boring, this is a serious math problem, I'm too happy, it's still boring. I don't think everyone follows Do you seem to want to sleep when you see a math book?"

"You poor boy, you've been acting weird all day long." Jiang Yi rolled up his sleeves, "I can't deal with you anymore, can I?"

"I was wrong, I was wrong, Brother Yi." Yu Wanzhou and Jiang Yi fought for a while, Jiang Xi pushed open the door and saw the two of them quarreling, and said disgustedly, "I said Jiang Yi, how old are you?" You are dead, and you are still arguing with Xiaozhou, can you be a good big brother?"

Jiang Yi withdrew his hand and tugged at Yu Wanzhou, "Let's go eat and ignore your brother-in-law."

"Okay, brother-in-law is going to eat." Yu Wanzhou pushed Jiang Yi away, Jiang Xi saw the attitude of the two, shook his head, and didn't know what to say.

The relationship between the two is quite good, Jiang Xi is completely helpless, he never thought that Jiang Yi could chat with Yu Wanzhou.The relationship is quite good. In the past, Jiang Yi didn't bother to talk to a kid like Yu Wanzhou, let alone talk about such things.Especially for everyone who put on a bad face, as if everyone owed him money, Jiang Xi still remembers it fresh.

Why has Jiang Yi changed his temper now?Jiang Xi couldn't figure it out, couldn't figure it out...then don't think about it.

Yu Wanzhou started to do his own thing after dinner, and they also started playing cards and so on.When it is almost March, everyone who should go to work will go to work, and those who should go home will also go home.When the two families add up, let's just go back.It's good for Yu Wanzhou's parents to relax for a while.Now that Yan Honghui's grandma is gone, it is enough to go back to his hometown during the holidays. Yu Wanshen, Yu Wanrong, and Yu Wanzhou all agree that the old couple will live in Yucheng.

Even Jiang Xi's parents persuaded the old couple, and finally they went to Yucheng.Because although Yu Wanzhou's house has been bought, but it has not been renovated, Yu Wanzhou decided to let his elder brother and sister worry about this matter. As for him—well, he will go to Princeton University in a while.Even if you want to worry about it, you can't worry about it.

After discussing with the family, everyone had to agree with Yu Wanzhou's suggestion. Before he returned to China, he would live in the house Yu Wanzhou bought so that he could take care of the old couple and let the old couple take care of their children without being too boring. .

After all, they didn't know anyone in Yucheng. The elder brother and sister had to go to work every day, and they didn't have time to take care of them. As for Yu Chuwei, he was not yet old enough to go to kindergarten, so it happened that the old couple could help take care of them.Although there is not much decoration, there are already some furniture, and Yu Wanzhou bought a hardcover room, which can be directly moved in.I just don't know how the quality is, and it will take a while to modify it.

In March, Yu Wanzhou boarded a plane to the United States, but this time no one came to see him off.He said that he knew the way, and he didn't need someone to send him off.When he arrived in Philadelphia, Lin Wei came to pick him up and asked him about the completion of his project.

Yu Wanzhou said confidently, "This subject is almost solved, and I will be able to solve it completely in April at the most. But it still takes a little time to verify."

"Take your time." Lin Wei said with a smile, "Have you visited the professor?"

"Don't worry, I've already read it. I also got some news, do you want to know?"

"What news?" Lin Wei smiled.

"Brother Song has graduated and is now an associate professor at Yucheng University."

"Hey, Junior Brother Song has also graduated. Has he finally stopped being stingy?"

"It's okay, you know, he's always been very stingy." The two chatted, and soon arrived at Princeton University, entered the campus, Yu Wanzhou returned to the dormitory to put away his luggage, and then reported to his family Safety.After thinking about it, I also sent a message to Jiang Yi——

[I have already arrived at Princeton University, the time difference is too big, don't call me in the morning if you have nothing to do! 】

When Jiang Yi saw this message, he was looking at the document.Being amused by Yu Wanzhou, I thought to myself, who is okay to call you.After putting down the phone, Xiao Li looked at Jiang Yi curiously. He had never seen his battalion commander smile so happily.No, when Researcher Yu was here before, he was still smiling happily.

Tsk tsk, isn't the battalion commander going to fall in love with someone?

Well, he already smelled the rancid smell of love.

After Yu Wanzhou returned to Princeton University, she immediately entered the state and continued to solve NP-complete problems.However, the time to solve it was a little earlier than he expected, and he had already solved this problem in mid-March.After checking, he published the proof of the NP-complete problem on arXiv at the end of March. On the day of publication, he rushed to Professor Weiteng's office aggressively.

Seeing Yu Wanzhou coming, Professor Wei Teng was quite puzzled.

Shouldn't Yu Wanzhou be doing her own project in the library now?Why did you suddenly come to his office?

"Ahem." Wei Teng organized his words, "Yu, what, how is the project progressing?"

"Professor, I'm here to apply for graduation. My doctoral project has been completed and uploaded to arXiv."

"What?" Professor Wei Teng was stunned, how long has he been here?In other words, how long has it been since Yu Wanzhou decided on this topic?It was July and August of last year, or even later, when he submitted the project application to determine the project.This has been solved?That's the Millennium Prize puzzle, not some random high school math problem.

"Solved... solved it?" Professor Wei Teng was stunned on the spot, "Is there any checking?"

"I checked the calculation four or five times, and there is no problem." Yu Wanzhou said with a smile, "Professor, you know that this is my doctoral thesis, and I have already solved it. Do you think I can apply for graduation?"

Professor Wei Teng took a deep breath, "Perhaps, let's try again."

"Yu, you also know the rules. Generally, you graduate in five years. You have just graduated from Princeton University in half a year. To be honest, this is the first time we have encountered this situation. It is the first time we have met you like this in any school. The situation." Professor Wei Teng thought for a while, and continued, "Since you are applying for a doctoral degree, then submit a paper application and I will hand it in. It may not be possible to pass, I can only try my best."

"Thank you, Professor Witten. However, I will greatly miss having academic debates with you."

Professor Wei Teng said with a smile, "Yu, even after graduation, you may still be able to stay at Princeton University. Besides, if your application is not approved, then you will still stay at Princeton University for a few years, and we still have More opportunities for academic debate."

"Thank you, Professor Weiteng." Yu Wanzhou left the office happily. At the moment Yu Wanzhou left the office, Professor Weiteng directly logged on to arXiv to search for keywords, and sure enough, he saw the article published by Yu Wanzhou on NP-complete problems. paper.

This kind of research ability is really not enviable or enviable.Anyone who has half of Yu Wanzhou's research ability will probably be laughed out of their dreams, right?

Professor Witten shook his head, great paper.He felt that the paper was very well written, and he had read it with relish from the very beginning.Even forgetting the time, Yu Wanzhou went back to her dormitory to tidy up, but didn't call Brother Lin Wei yet.He didn't know whether his application would be approved.

"My God!" Langlands stood up and tidied himself up.

Opening the door, he nodded to Lin Wei who was walking, "Good morning, Lin!"

"Morning Professor Langlands." Lin Wei looked at Professor Langlands curiously and said, "Professor, who is this?"
