After a few brief conversations, they discovered something else amazing!

Most of them usually play with their mobile phones, sleep, and listen to the class only those who sit in the front row, but they all listened attentively to the whole class today!

"I feel that Mr. Li's voice has a special charm, it is very comfortable to listen to, and I follow his voice unconsciously!"

"And every word that Mr. Li said on the podium, even if it is more esoteric and difficult to understand, it is easy for people to understand the meaning!"

......

In an ordinary math class, after the students confirmed each other, they were surprised to find something extraordinary.

Ding Shaoyuan, the dean of the Department of Mathematics, has been frowning, holding a pen in his right hand to write and draw in a new notebook, and has used up more than 20 pages of paper, his expression is very entangled, as if he is facing a huge difficulty.

"Dean Ding, Mr. Li is done!"

Li Changqing was specially hired by Qiu Lexian to Wen'an College, and after Li Changqing finished class, Ding Shaoyuan should have said a few words, but Ding Shaoyuan lowered his head, and Liu Fengxiang, the vice president who was sitting next to him, had to whisper in Ding Shaoyuan's ear.

Ding Shaoyuan finished immersing himself in his own world and continued to write in his notebook without any reaction.

The class has ended, the students are waiting, Li Changqing doesn't care about the scene, and he packs up a little and prepares to go back to the mountain.

"Dean Ding?", Liu Fengxiang was anxious in his heart, and asked again.

"Smack!"

Ding Shaoyuan slapped the pen in his hand on the table, and the audience was silent in an instant, and they all turned their puzzled eyes to Ding Shaoyuan.

"What did Lao Ding do, did he take the wrong medicine?"

Liu Fengxiang and the second monk were confused, so he asked a few words, Ding Shaoyuan would not be so atmospheric!

And I heard that President Qiu worked hard to invite Li Changqing, and if he embarrassed Li Changqing, wouldn't it be tantamount to saving Qiu Lexian's face?

"Finally figured it out!", Ding Shaoyuan smiled like a chrysanthemum and pointed at Li Changqing and said.

Li Changqing had already arrived at the door of the classroom, so naturally he didn't notice Ding Shaoyuan's words.

"Teacher Li, oh, no, Master Li, don't go!"

Ding Shaoyuan was afraid that Li Changqing would leave, so he shouted loudly, startling Liu Fengxiang.

"What's going on with this old ding?", Liu Fengxiang muttered to himself depressedly.

"What's the situation, Dean Ding vs. Teacher Li?"

The students were also stunned by the scene staged by Ding Shaoyuan, which was very different from what they expected.

"Dean Ding, what's the matter?", Li Changqing heard Ding Shaoyuan shouting to himself, turned around and said to Ding Shaoyuan.

"Master Li, you can really calm down!"

Ding Shaoyuan looked like I understand you, and smiled so much that the crow's feet between his eyebrows and eyes were twisted together.

Liu Fengxiang and the students all breathed a sigh of relief, looking at Ding Shaoyuan's tone and expression, it didn't look like he was about to quarrel.

"What do you mean?"

Li Changqing is very aware of his own peculiarity, some things that seem ordinary to him may seem incredible in the eyes of others, and he is not sure which ability he has shown makes the dean of the mathematics department who is more than half a year old so restless that he can't control himself.

"The method you just used to prove Fermat's theorem is different from that of the English mathematician Andrew Wiles!"

Ding Shaoyuan was quite proud and said with great certainty.

Liu Fengxiang did not specialize in number theory, but when Andrew Wiles thoroughly proved Fermat's theorem, it caused a great sensation in the mathematical community at that time, he was a graduate student, and he had nothing to do to study the process of Andrew Wiles's proving Fermat's theorem, but the time was too long, and he couldn't remember it clearly.

"It seems that it is true, it is difficult to say that Mr. Li Changqing proposed a second method to prove Fermat's theorem?"

Liu Fengxiang reacted, although Fermat's theorem had been proved as early as 1995, but after all, it was a problem that had not been solved in the history of mathematics for three hundred years, Li Changqing was able to propose the second proof method, although it was different from the significance of his proof of Goldbach's conjecture, but at least it could attract wide attention in the academic circles of China and even Asia, no wonder Lao Ding was so excited, and it was also a valuable qualification for him!

"Oh, that's what you're talking about! I did prove it by my own method, and the method should be correct!"

Li Changqing's reaction was very flat, he once proved the Goldbach conjecture that was more difficult than Fermat's theorem, just like a student who often scored full marks, one day he scored ninety-five points, and others came around and praised the student for taking the test very well, but in the eyes of the student, this is not his highest level, there is nothing to be surprised about.

"Master Li, I know that you once proved Goldbach's conjecture and took off the crown jewel of mathematics, if you just use a new method to prove Fermat's theorem, I will be very impressed, but I will definitely not be surprised! But your new proof method is more than ten times simpler than Andrew Wiles, this is a very significant breakthrough in the field of number theory, so that our research in the field of algebraic number theory directly surpasses Europe and the United States, so don't be modest!

Ding Shaoyuan couldn't wait to have the words 'I have already seen through you' engraved on his face, and said to Li Changqing very excitedly.

"I witnessed a major breakthrough in the field of algebraic number theory without paying attention, no, I have to take a selfie, send a circle of friends to prove that I am on the scene, and pretend to earn a circle of likes!"

"It's amazing, some young mathematical geniuses, after a breakthrough in a certain field, basically do nothing all their lives, but Mr. Li proved Goldbach's conjecture and proposed a new ten-fold simple proof method for Fermat's theorem!"

"I feel that Mr. Li's calm face is in stark contrast to Dean Ding, and it looks inexplicably funny! Although modesty is the traditional virtue of our Chinese nation, don't be modest when you should be proud, I give Mr. Li a score of one hundred and one, and I am not afraid of his pride!"

"Call Teacher Li crazy!"

......

Although the students couldn't figure out how Li Changqing's method of proving Fermat's theorem was better than that of Drew Wiles, it did not prevent them from understanding Ding Shaoyuan's words, and little stars could appear in their eyes when they looked at Li Changqing.

"Hehe, Mr. Andrew Wiles proved Fermat's theorem twenty years before me, and my method is a little better, but there is nothing to be proud of!"

Li Changqing was very happy to see the teachers and students, and said with a smile.

"The master is really the master, at such a time, he is still so calm, it is really admirable!"

Ding Shaoyuan stared at Li Changqing's face for a long time, and then he believed that Li Changqing's heart really didn't have any waves, not like pretending, and said convincingly.
