Time passed little by little, and all the white paper that had been brought to the classroom was used up, and it was being placed on the table next to the seat. It is densely covered with all kinds of symbols and letters. If you ask an ordinary science student at Mizuki University to look at it, you may be able to understand what every letter and symbol means, but if you connect them all, it is almost the same as reading a book from heaven.

Not far behind Junxin, a girl has been paying attention to Junxin for a long time. She is a senior in the Faculty of Arts, and it is time to graduate. However, hesitation has high requirements for himself, so he took many courses, resulting in the fact that although he has reached his senior year, the heavy workload of his studies has not decreased, but has a tendency to increase, so he naturally applied for an all-night study room.

But after all, it's only the 80s, and there aren't many overnight study rooms in the school, and the school has just started, so basically no one will come from the study room, and generally go to the library reading room to study until the library is closed, and few people come to this classroom.

And when she first came to this classroom today, she found that there was already a person in the classroom who didn't know what he was writing. At first, she thought it was a student from the Faculty of Arts who was writing something. When he came to Junxin's back and glanced at it, he found that it was a student from the mathematics department who was calculating something, and when he saw Junxin's fascination, the girl didn't make a sound to disturb.

However, as time passed, the girl found that it seemed that after such a long time, the boy in front of him had maintained the posture of calculus for a long time, and during this period, the girl had gone to the bathroom, and had gone to the corridor to solve the problem of lunch and dinner, but he had never seen Junxin have such activities. It seems to be completely silent in its own world. The only change is that there is less and less white paper around you, and more and more paper full of symbols.

"Who is he? What are you doing? The girl couldn't help but feel that she was interested in this boy, and Mizuki's math department had just been rebuilt, so this boy was either a freshman or a sophomore. A freshman or sophomore stayed up in the all-night study room at the beginning of the school year, and the girl said that it was the first time she had seen her in more than three years of college.

In this way, the girl is sometimes immersed in her own books, and sometimes she looks up at Junxin. And just like that, time passed little by little. When Liu Ya felt that she was about to lose her stomach and wanted to take a little rest, a long exhalation suddenly came to her ears, and the girl suddenly looked up and found that the boy sitting in front of her finally stopped his pen at this time, and looked straight at the manuscript paper in front of him.

Junxin looked at the last page of the manuscript paper, that is, the page in front of his eyes, and couldn't help but let out a long breath, finally proving that it was completed. In this world, the proof of Modell's conjecture was three years earlier than in the previous life.

However, Junxin still felt a sense of loss, after all, this was when he visited Professor Wiles in his previous life, and in the process of discussing Fermat's theorem by the way, Professor Wiles mentioned some of the mathematical thinking of Fermat's theorem with himself, he was just a retrospective proof process of Modell's conjecture on the premise of knowing the answer and way of thinking, and after all, he was still not as good as those who really made pioneering achievements.

Suddenly, Junxin felt a rumbling in his stomach, and then he noticed that the lights were on in the classroom, and the sky outside was completely dark. I couldn't hear the noise of the campus at night, so I focused my eyes on the clock on the wall, and the time was already pointing to half past three.

Junxin couldn't help but be startled, at half past three, he sat in this classroom in less than ten o'clock, and before he knew it, seventeen hours had passed. And seventeen hours of a lot of mental exertion, even with his own body is a little weak and hungry.

"I still have a little food here, you can have some!" Just when Junxin was distressed, a heavenly voice sounded behind Junxin.

Junxin couldn't help but turn his head to look, his eyes suddenly lit up, compared with the girls who wore heavy makeup at every turn in later generations, the girl in front of him at this time was delicate and moving, although she was not that beautiful type, but her body may be the reason for long-term contact with classic books, and she has a bookish atmosphere, which converges into a peculiar and comfortable unique temperament, which belongs to the kind of girl who is good-looking. However, Junxin doesn't care about the girl's temperament, but about the half of the baked cake that the girl is holding in her hand.

"Thank you, senior sister?!" The tone is not very sure, but after seeing the temperament of the girl, I am sure that although the girl's family background is not necessarily very good, it should not be too bad.

Junxin was just about to get up, suddenly his feet were soft, his body was a grin, and then he sat down suddenly, Junxin knew that this was caused by poor blood circulation in the entire lower body for a long time, so he had to show a wry smile to the senior sister.

The senior sister smiled, expressed understanding, stepped forward in a few steps, picked up her cup by the way, and handed it to Junxin along with the baked cakes.

"My name is Jun Xin, the gentleman's king, the letter of believe! Freshman math freshman, what about the senior sister? What do you call it? ”

"Oh, my surname is Hu, it's good if you call me Hu Xin, Gu Yue Hu, ecstatic Xin. Senior College of Letters Modern Literature Major! Hu Xin handed the things to Jun Xin, sat down next to Jun Xin, and asked, "When I came in the afternoon, I kept seeing you calculating here, what are you doing?" ”

"A conjecture!" Junxin ate the baked cake in his mouth and said vaguely, "After the exam in the morning, I saw that there were some very interesting questions in the additional questions, which gave me some ideas, so I found a random place to sit down and wanted to study it. ”

"I can understand this, my dad is also a mathematician! So when I see you like this, you know that you are caught up in your train of thought! ”

"Thank you for the! Hope I didn't bother you just now! Junxin smiled, then looked outside and said, "It looks like I'm going to be sprayed by the counselor tomorrow, and I won't be able to go home at night the second day of school, which is really..." Junxin shook his head, a little helpless.

"It's okay, I'll testify to you then, I think the school can understand it!" After a pause, he continued, "What conjecture are you proving? ”

"It's a conjecture in the process of proving Fermat's theorem, called the Modler conjecture, and when I was taking the exam yesterday morning, I saw the first question of the additional question, the number theory question, and then I had a little inspiration. I came here after the exam in a hurry, and in order to grasp this inspiration, I kept calculating. ”

"Is there a result?" Hu Xin asked.

"Well, when the mind is opened, there is a result. I think it's pretty good. Because this conjecture is related to the other two conjectures, I have to carefully revise it from beginning to end. If the senior sister is tired, leave me alone, I'll clean it up and prepare to calculate it again. See if there are any omissions and flaws. ”

"It's okay, you don't have to worry about me, I'll just watch it, don't bother you!"

Junxin nodded and continued to bury himself in the stack of manuscript papers.
