Peng Chuan graduated from the School of Mathematics of Shanghai Jiao Tong University in the 90s of the last century, and later went to study abroad in the Department of Mathematics of Princeton University, and at that time became a student of Lian Zhengxing, who was teaching at Princeton University.

After graduating with a Ph.D., he returned to Shanghai Jiao Tong University to teach.

However, during his tenure as a teacher, he was criticized by the then dean Wang Shuo for his education of graduate students, that is, the retired former dean of the School of Mathematics, Academician Wang.

And the main reason is that he squeezes graduate students very excessively.

他带了大概七年的研究生，在期间，抢过自己学生十几篇论文，还让自己的学生干各种的杂活，以至于在他这里学生的延毕率是全院最高的。

Of course, the delay rate is not the main problem, the main problem is that he oppresses the students, which has led to depression in at least five students, and one of them almost committed suicide.

The student sent an email to his best friend before committing suicide.

Reading between the lines, he revealed a clear inclination, so much so that his friends came to him by train overnight, and finally found him in his dormitory with his wrists cut.

Fortunately, the student hesitated for a day and a night before cutting his wrists, and at the same time, he did not cut the artery, and the bleeding rate was relatively slow, so that when his friend arrived, although the condition was serious, it was still too late to be treated, so he finally survived.

At that time, the Internet was not as convenient as it is now, so public opinion did not spread, Shanghai Jiaotong University quickly suppressed the matter, appeased the student and his family, made sufficient compensation, and changed the tutor, of course, all other students in Peng Chuan also expressed strong dissatisfaction in this incident.

As a result, Peng Chuan was removed from his status as a graduate supervisor, and all other students were able to change their supervisors.

Wang Shuo, the dean at that time, naturally expressed his dissatisfaction with Peng Chuan, talked with him many times, and criticized him very harshly.

The most important thing is that Peng Chuan is an excellent student who graduated from them, and even Wang Shuo was Peng Chuan's teacher at the beginning.

Therefore, no matter how harshly he criticizes, he hates iron and steel.

But because of this, Peng Chuan was dissatisfied, and then secretly contacted his mentor at Princeton University, Lian Zhengxing, hoping that Lian Zhengxing would help him go to Beijing University.

At that time, Lian Zhengxing had returned from Princeton University to the School of Mathematics of Shanghai Beijing University and served as the deputy dean, so he still had this power.

In addition, Shanghai Jiaotong University also knows that family ugliness cannot be publicized, so no one has revealed this matter.

So, even Zhengxing didn't know what he had done as a student, and later checked that his student had returned to Shanghai Jiaotong University for a few years, and he had not slackened at all, and he had published so many papers, many of which were of good quality.

In addition, Peng Chuan's performance as his student at Princeton University also performed well, which left a good impression on him, so he worked for a while and let Peng Chuan come to Beijing University as an assistant professor.

Of course, Shanghai Jiaotong University did not keep him at all, and sent him away like a plague god.

After coming to Beijing University, Peng Chuan became much more restrained, and started academics with an open mind, so he changed from an assistant professor to an associate professor, and was finally promoted to a full professor.

Of course, the things of that year, after all, the paper can't hold the fire, and a few years later, the leaders of Beijing University also knew about it, but at that time, Lian Zhengxing had become the dean, facing the bitter pleading of the former students, and Peng Chuan, who came to Beijing University, performed well, not to mention how good he was academically, but there were still some achievements, so he thought that he had changed his ways, so he was only punished with three glasses of wine, and then symbolically punished, so he said goodbye.

In this way, Peng Chuan, who became a professor at Beijing University in the name of righteousness, re-inflated his heart, and at the same time became disdainful of Shanghai Jiaotong University, he also regained his grudge against the events of that year.

"Lao Tzu is now a full professor at the School of Mathematics of Shanghai Peking University, Huaguo No. 1 School of Mathematics, and you Shanghai Jiaotong University didn't even leave a word back then, so you let me go."

And now seeing a talent like Li Mu in Shanghai Jiaotong University makes him even more unhappy.

Of course, holding a grudge is a grudge, and he has no way to retaliate against the School of Shanghai Jiaotong University, after all, he is also a Shanghai Jiaotong University, so he is not so easy to mess with.

Until today, he listened to Li Mu's report, saw this person who should have been his apprentice, and proved the twin prime conjecture, for him, even if he applauded on the surface, smiled, and celebrated for the Chinese mathematical community, but his heart was also crawling in the dark, hoping that Li Mu's proof would be found out to be wrong.

Especially knowing that their Beijing University Academy had made a condition that he was envious of and wanted to keep Li Mu, but Li Mu actually refused, which not only made him ashamed in his heart, but also hated Yu Xu even more.

But again, he himself is not capable of revenge, because he has no reason.

However, he didn't expect to hear Fan Pairen's words unexpectedly.

Although he didn't think that Fan Pairen was really one step away from the proof of the twin prime conjecture, he saw that he was very careful, and said that many mathematicians in the car had heard it, and it was he who first told Li Mu to combine the circle method with the finite field.

Even Fan Pairen listed some mathematical formulas for him on the spot, indicating that he had a purpose.

彭川看到了这些式子，竟然还有一定的逻辑性，这就让他心中对范湃仁算是正式地相信。

"Very good, very good, I can see that Professor Fan, you do have such a talent for mathematics."

Handing back the draft paper that Fan Pairen gave him, Peng Chuan said with a smile: "I will definitely help you get what you deserve, and then I need your cooperation, I will contact my reporter friend to interview you, only in this way can we let the public know about this matter." ”

"Good! Thank you, Professor Peng, you're weird, at least the best of all the professors I know. ”

Fan Pairen took back the scratch paper.

His heart was also pounding at this time-because he didn't tell Peng Chuan that sixty or seventy percent of the formulas on this draft paper came from the content of Li Mu's report, and then changed slightly, so these formulas seemed logical.

However, he didn't feel any guilt in his heart, because he now even believed that the basis of Li Mu's proof came from the direction he provided.

So even if he uses the content of Li Mu's report now, he feels that it is equivalent to using his own.

If you use it, you use it.

And Peng Chuan didn't know what Fan Pairen was hiding at all.

It's like what he hid from Beijing University when he first entered it.

他笑着站起了身，向范湃仁伸出了手：“我人好不好都是次要的，最主要的是应该让你这样有才华的数学学者，不能被埋没了。 ”

Fan Pairen's face was also filled with a bright smile: "Then it's troublesome Professor Peng, and when the matter is completed, I will definitely thank you." ”

"I don't dare to hope for the Fields Medal, but if I can come to Beijing University to teach, it will be my life's wish."

"No problem."

Peng Chuan drew a flatbread.
