There are not too few students who choose to stay in Tsinghua University during the summer vacation.

After all, summer vacation is not like winter vacation. There is a day like Spring Festival when you have to rush home to reunite. Staying in school can have an excellent learning atmosphere.

In less than two months of summer vacation, Cheng Nuo was as busy as he was in the past few months, but it was hard to say that he had a few free days.

Cross-school cooperation and exchange projects, and proof of weak BSD conjectures.

These two things take up almost 70% of Cheng Nuo's time every day besides eating and sleeping, so he can only take some time to play a few games of King of Kings, eat chicken, and relax.

Everything is going on in such a steady and progressive way.

…………

Summer is scorching like fire.Kyoto in the summer is really not a place for people to stay.

Cheng Nuo, who was supposed to be at the beach at this time, blowing the cool sea breeze, was standing under the sun, holding a bottle of iced drink in one hand, wiping the sweat dripping from his forehead with the other, and walked into the building of Peking University. Innovation practice base.

In the office specially assigned to Cheng Nuo, all four members of the research team were there.

"Cheng Nuo, you've finally arrived. I thought you had a heat stroke on the way!" Sheng Fei walked up with a smile.

"Our side in Kyoto is not bad, you go to Jinling to feel it, it will definitely be so hot that you will doubt life." Yang Xiao also came to intervene.

Half a month's running-in period passed, and the five of them became acquainted with each other.

The attitude of the few people towards Cheng Nuo was not the same contempt at the beginning, but an attitude of being equal to themselves, or...higher!
Judging from Cheng Nuo's astonishing performance during this period, Cheng Nuo's image in their minds has been completely elevated.

What's more, Cheng Nuo is only less than 20 years old now!

Future achievements are unpredictable!

Even the guards who had some problems with Cheng Nuo before had to say "convinced" to Cheng Nuo at this age.

"I heard that sister Yi Ge is in some trouble, I'll come over and have a look." Cheng Nuo asked while taking the wet wipes from Sheng Fei.

Originally, Cheng Nuo's research work was not included in the research team's research plan for the past few days.No, I heard that senior sister Yi Ge encountered some problems with her project. Cheng Nuo, who just bought a watermelon in the dormitory to relieve the heat, was summoned here urgently.

Sister Yi Ge came out a little embarrassed at this moment, and stood in front of Cheng Nuo, her tone was soft and weak, and she said apologetically, "Cheng Nuo, I'm sorry, it's so hot, so I asked you to come here."

"Sister Yi Ge, it's okay." Cheng Nuo smiled, "It's not that far, just a few steps."

"By the way, what is it that you guys can't solve?" Cheng Nuo asked curiously.

Sheng Fei spread his hands helplessly, "The fields we are involved in are all biased towards geometry, otherwise we wouldn't be recruited here."

"And the problem that Yi Ge encountered belongs to the problem of linear calculation in combinatorics, and there is nothing we can do to help."

"So, call your all-rounder in mathematics and see if there is any way."

Sheng Fei briefly told Cheng Nuo what happened.

Cheng Nuo nodded, expressing his understanding, and asked, "What about the specific question?"

"This way." Sheng Fei led Cheng Nuo to a desk.

And that desk has been used by Yi Ge during this period of time.

"Yi Ge, please tell Cheng Nuo briefly." Sheng Fei said.

Yi Ge nodded with a serious face, bent down, opened a file on the computer, stroked the hair next to his ear, and said, "The research I am in charge of is the derivation process of the theorem about the integrable symplectic map."

"According to what Cheng Nuo said, logically speaking, we should derive four equations related to integrable symplectic maps. The first two theorems are fairly simple, and can be derived with only a few simple logical formula steps."

"But when it comes to the third theorem, that is, in the process of using Lax to express a L(λ)D(λ)=?(λ)∑φ^2, it is necessary to use some knowledge of combinatorics in order to reach the conclusion smoothly. "

"Is it here?" Cheng Nuo glanced briefly, and pointed to a line in the document.

"Yes, that's it. From formula two to formula three, I don't understand the specific derivation steps." Yige nodded like a chicken pecking at rice.

Cheng Nuo turned around, pulled a chair, sat on a blank desk next to him, stretched out his hand,
"Paper, pen!"

Yi Ge graciously handed Cheng Nuo a pen and paper.

"Don't bother me." After saying this, Cheng Nuo lowered his head and wrote out the calculations on the paper with a pen.

【α=﹤?φ1，φ1﹥（2﹤φ1，φ2﹥-1）/﹤?^(-1)φ1，φ1，……直接计算：∑dφ1j∧dφ2j=∑nj……】

5 minutes later……

pat!

Cheng Nuo closed the cap of the pen, picked up the A4-sized draft paper that was written on both sides, and handed it to Yi Ge who was behind him.

"This is the derivation step, take it!"

After finishing speaking, Cheng Nuo straightened his clothes, waved his hands, and left the office without looking back, leaving everyone with a handsome and unrestrained back.

Downstairs, Cheng Nuo, who walked out of the building in an extremely handsome posture, was directly dazed by the oncoming heat wave.

Sister, if I knew it earlier, I would stay in the air-conditioned room for a while and come out. This is the time when the sun is at its worst.

There was nothing he could do, he had to finish pretending even though he was having a hard time, facing the temperature of nearly [-] degrees, Cheng Nuo wiped his sweat and walked back to the dormitory.

…………

After Cheng Nuo's pretentious performance in the office, Cheng Nuo's leading role among the five gradually became apparent.

The progress of the project has been soaring at a speed visible to the naked eye.

On August 8, Cheng Nuo started the fall semester of his sophomore year. If nothing else, it would also be his last fall semester as an undergraduate.

Because, in less than a year, he will get his undergraduate diploma and a degree certificate in mathematics, saying goodbye to his undergraduate career.

The course, of course, was as intense as ever.

However, taking some time out of his busy schedule, Cheng Nuo still found an opportunity to participate in the orientation work for freshmen on the first day of school.

Looking at the immature faces, full of longing and longing for the university, stepping into the campus, Cheng Nuo couldn't help but want to shout loudly:
"Fucking old man finally became a senior!"

After being someone else's junior for a year, Cheng Nuo finally had the chance to call someone his junior!
At the same time, the benefits of seniors are not the only ones.

In terms of competition for freshmen, those of them who have been in school for a year have a much better advantage than the cute new students who have just arrived.

School girl, she is ours!
Senior, it's ours!
Junior is also ours! ! !
