After twelve hours of calculation, Xu Yun always maintained his excitement under the effect of the energy elixir, as if he could not feel the negative feelings such as tiredness, sleepiness and even exertion that should appear in his body, and his thoughts continued to burst out of his mind to help him continue to improve the final argument of his graduation thesis.

……

“gcd(Fm，Fn)=Fgcd(m，n)”

……

"Fn is a prime number, n ≠ 4, n must be a prime number."

……

"From Eq. 4, Eq. 5, Eq. 6, F(x) and P(x) are identical in defining domains."

"According to the infinity of prime numbers, it can be obtained that there are infinitely many primes in the sequence Fn."

"Done."

When Xu Yun finished writing the last step of the formula, he successfully proved that there are infinite primes in the Fibonacci sequence, and at the same time completed the demonstration of the topological group theory of the method he used.

It can be said that this method builds a bridge in number theory and helps mathematicians to reach those conjectures.

But whether it can be found and used well is a big question.

However, with this milestone success, the difficulty in number theory is no longer a difficulty.

As long as he is given time to continue to optimize the topological group theory, I believe that it will be a matter of time before Goldbach's conjecture is proven.

Almost the next second Xu Yun completed the proof, and before he could enjoy this great joy, the effect of the energy elixir suddenly quickly withdrew from his body like a tide.

A high-intensity calculation that lasted more than a dozen hours, plus no food in between.

Didn't even take a sip of water.

The hunger and exhaustion that surged him made him fall on the table like a deflated ball.

Just when he was about to slow down a little and then go directly to the school cafeteria to eat, he suddenly saw many classmates around him running quickly to his location, and there were shouts full of worry in his ears one after another.

"Xu Shen seems to have fainted, everyone hurry up and help."

"It must be too long since he has eaten and is hungry, who will help carry him to the infirmary quickly."

"I actually insisted on it from the morning to the present, compared to Xu Shen's learning attitude, I am simply a waste."

"Don't forget to pack the scratch paper on the table for Xu Shen, but don't lose it."

……

Although Xu Yun wanted to say that he was fine, he really couldn't resist the enthusiasm of the classmates around him.

In addition, he had no strength, so he had to let a strong male classmate carry him.

However, it may be because the other party is more worried, and he fell asleep under the trot on the road.

And he can only be bitter and happy about this, thinking that his classmates at school are all weird.

I don't know how long it took, but when he opened his eyes again, his vision was suddenly occupied by a girl in a white coat.

"Classmates."

"How does your body feel?"

Out of the corner of his eye, he glanced at his surroundings slightly, and realized that he had been sent to the school infirmary.

Hurriedly sat up, shook his head, and replied, "I'm fine, doctor." ”

As soon as the words fell, I saw Qian Yudong, Zhao Yuefeng and Zhou Qi, who came over at some point, surrounded him, and looked at him with a look of admiration and admiration in their eyes.

After making sure that Xu Yun was fine, he said it like pouring beans.

"It's not that I said you Xu Yun, you worked too hard this time, and you actually stayed in the library for more than ten hours without eating or drinking."

"If it weren't for someone from our professional class in the library to see it, we wouldn't know you'd be back at school." Zhao Yuefeng took Qian Yudong's words and hurriedly added.

Xu Yun knew that they all cared about him, and the corners of his mouth barely squeezed out a smile to explain to the three of them.

"I was working on my graduation thesis in the library, and I didn't have much time to think about when I was inspired."

"Let's eat something first." At this time, Zhou Qi next to him took out the food from the bag and handed it over and said, "We passed by the restaurant when we came and bought it." ”

Xu Yun hasn't eaten for so long, and when he sees food, he will take care of his image.

"I'm not going to be polite to you."

He replied with a smile, took it from Zhou Qi's hand and immediately ate it.

As the food entered his stomach, he regained his strength a little, and asked the three of them about the situation in the library.

"Who sent me here, didn't it affect the library?"

"A senior from the Institute of Objects carried you over and helped you put everything in your backpack, and we already thanked you when we came." Zhou Qi explained the situation clearly along Xu Yun's question, and then spoke again as if he had thought of something: "But you are popular again at school this time, and some people say that you are proving that your conjecture has unfortunately gone crazy." ”

The mention of this matter immediately opened the topic, and Qian Yudong and Zhao Yuefeng echoed one after another.

"I guess the whole school knows about your affairs in the library now, and everyone admires it."

"Let's just say that this durability, who dares not to admire."

Xu Yun didn't mind the ridicule of a few people, anyway, he had long been a celebrity in the school.

It's not a big deal to be second ranked.

Anyway, his graduation thesis has been successfully demonstrated, and the next step is to write it according to the format of the thesis.

Just as a few people were chatting, Xu Yun suddenly noticed that Tang Yanshan hurriedly walked in from outside, and the words of concern had already spit out of his mouth before he arrived.

"Are you okay kid?"

"Professor Tang."

Unexpectedly, this incident also alarmed Tang Yanshan, and he hurriedly got off the hospital bed without caring about the food in his hand.

"Anything I can do, it's because my classmates are too enthusiastic."

"It's just an undergraduate thesis, can it be difficult with your strength?"

"Do you need to fight so hard?"

Tang Yanshan automatically ignored Xu Yun's hippie smile and seriously criticized his behavior.

Although he didn't know the specific direction of Xu Yun's graduation thesis, it would not be difficult to choose the algebra field he was good at.

There is still more than a month left before the graduation season, and I am sure that I will be able to complete it smoothly if I write it slowly.

If you do something like the library today, if it affects your body, it will be too much to lose.

Originally, he was about to go home from school, but he happened to hear a passing student talking about it, so he asked Xu Yun's location and hurried over.

It wasn't until he saw that Xu Yun had no problem that his hanging heart was completely put down.

Xu Yun understood that Tang Yanshan was doing this for his own good, so he didn't choose to refute anything.

Always have a smile on his face when he speaks.

"Isn't it in a better state, but I'm worried that if I stop halfway, my thinking will become confused, so I continue to calculate and improve."

"Fortunately, today's efforts were not in vain, and my graduation thesis was basically completed."

"Done?"

Tang Yanshan didn't react at first, and only after repeating a sentence did he look back and a little surprise appeared on his face.

"You're saying your dissertation is ready?"

"It's just the finishing touch and formatting." Xu Yun nodded in acknowledgement, and then said to Tang Yanshan: "I still want to trouble Professor Tang and Dean Qin, my defense time will be set for next month." ”

Xu Yun knew that Qin Xiangxin was going to invite members of the Mathematical Society to form a jury with the highest specifications to participate in his defense, so the time must be determined in advance.

After confirming that Xu Yun had really completed his graduation thesis, Tang Yanshan was not too surprised.

A smile finally appeared on his face, and he expressed his expectations for Xu Yun's graduation defense.

"I'll tell the dean about this, and I'll let you know when the specific time is confirmed."

"I'm looking forward to the graduation thesis of the world's math problem Hodge conjecture prover."

"I am afraid that the academic value of a graduation thesis that can be completed in the library without eating or drinking will not be too simple, so don't let our jury down at that time."

Since Tang Yanshan had previously said that he had no intention of helping him change his thesis, Xu Yun temporarily sold it.

"Don't worry, Professor Tang, I won't let you down on the day of the defense."

After saying this with confidence, and then watching Professor Tang leave, the two did not continue to talk.

Xu Yun can communicate generously with Tang Yanshan like friends, but it doesn't mean that Qian Yudong, Zhao Yuefeng and Zhou Qi dare too, after all, whether they can graduate successfully or take the postgraduate examination in the future, Tang Yanshan still plays a very big role.

If that sentence is wrong and leaves a bad impression on Tang Yanshan, it will be too late to regret it.

Therefore, when Xu Yun and Tang Yanshan were talking, the three of them always stood beside them obediently.

I didn't say a word during the whole process, and tried to treat myself as a transparent person.

It wasn't until Tang Yanshan's figure completely disappeared from sight that the three of them breathed a sigh of relief, and reacted and chatted with Xu Yun about their graduation thesis.

"Brother Yun."

"You're really going to defend your graduation?"

"If Dean Qin and they have time, it should be next month." Xu Yun answered truthfully in the face of Zhao Yuefeng's inquiry.

"Brother Yun will be a graduate student by then, and he should change the dormitory."

"Xu Yun has already finished his undergraduate course and will definitely graduate." Although Qian Yudong, as the head of the house, was also a little reluctant to let Xu Yun leave, he still took Zhao Yuefeng's words and added.

After all, as a roommate in the same dormitory, he must hope that Xu Yun will get better and better in his studies.

Xu Yun has actually thought about this problem, he now has a full-time driver sent by the company, and in fact, the number of times he lives in the dormitory has decreased, and even if he becomes a graduate student, there is no need to change the dormitory.

The thought stopped here, and he immediately replied, "Even if I go to graduate school, I will continue to live in our dormitory." ”

"That's great, we can't help you leave." Zhao Yuefeng's face suddenly overjoyed when he heard this.

On the side, Zhou Qi thought of something, and couldn't help asking: "Xu Yun, which major are you going to study in graduate school?" ”

"The preliminary direction is there, but we still have to discuss it with the department." Xu Yun paused for a little two seconds to give such an answer.

Previously, he had heard Qin Xiangxin mention two sentences, saying that the department had formulated new regulations for his studies, so he wanted to wait until he completed the graduation defense to inquire in detail.

In the following time, Xu Yun didn't stay in the school infirmary, so he took his backpack and returned to the dormitory with Qian Yudong.
