In the first row of seats in the auditorium, in the middle of the seat, sat an old man wearing black-rimmed glasses.

He quietly watched Li Mu's speech on the stage, and his face did not show too much emotion.

At this time, someone next to him asked him: "Professor Zhang, what do you think Li Mu is planning to do?" ”

"I don't know, just watch quietly, don't think too much."

"The twin prime conjecture is hard, but that doesn't mean it can never be solved."

"It's like a hail conjecture."

The old man's face was calm.

The person next to him nodded, "That's right." ”

The old man said again: "Of course, if you start the discussion from the Galois domain, it is indeed an interesting angle. ”

The man next to him nodded: "Indeed, I haven't studied the twin prime conjecture for a long time, and Li Mu's perspective has indeed brought me some inspiration." ”

The old man did not respond to this sentence, and while remaining silent, his eyes were fixed on the blackboard where Li was writing.

If you have a better understanding of various celebrities in the mathematical field, you can quickly recognize that this old man is Mr. Zhang Yitang, who made a huge breakthrough in the twin prime conjecture.

Zhang Yitang's life can be described as bumpy, but the so-called late bloomer refers to people like him.

早年的他当可谓是天才，在1978年就进入了上京大学数学学院，本科毕业后，师从潘成彪，攻读硕士，之后又在当时校长的推荐下赴米留学。

However, the experience of studying in the United States made his life not improve for half of his life.

Because of his doctoral supervisor, he finally failed to get a letter of recommendation from his supervisor after graduation, and therefore no relevant academic unit was willing to accept him.

So much so that he worked as a delivery boy after that, did odd jobs in motels, lived in basements, wandered, and wandered.

But at the same time, he never gave up the study of mathematics, and finally completed a huge breakthrough in the twin prime conjecture in 2013.

His paper was submitted to the Annals of Mathematics, and the average time to receive a paper in the Annals of Mathematics was two years, but his paper was so rigorous that the reviewers of the Annals of Mathematics decided to accept his paper within three weeks.

This speed is the fastest rate of receiving papers in the 130 years since the founding of the Annals of Mathematics.

Of course, because of this, the twin prime conjecture has not only become synonymous with him, but he also pays close attention to the progress of the twin prime conjecture.

So Li Mu's report, he was not absent at all.

Li Mu had successfully proved the hail conjecture before, and now that he had set his sights on the twin prime conjecture, Zhang Yitang wanted to know if he could create a miracle again.

If it can be realized, it will be regarded as the fulfillment of one of his wishes - that is, to see the solution of the twin prime conjecture in his lifetime.

Because he wanted to know whether the method he came up with at the beginning could finally solve the twin prime conjecture with continuous improvement.

If it were the other way in the end, then he would be glad for the mathematical community, and the spark of different ideas eventually led to the same goal, which is the greatest charm of mathematics, as the saying goes, all roads lead to Rome.

Of course, he would be happy if it was ultimately proved based on his method, because it meant that his original method had unlimited potential.

……

At the same time, in the seats in the third row, there were also several young mathematicians quietly watching Li Mu's narration.

"Lao Yun, what do you think?" Suddenly, a man turned his head to look at the person next to him.

"I'll sit and watch."

The man called Lao Yun replied.

His name is Yun Wei, and he is one of the most accomplished young mathematicians in China.

He has won the Ramanujan Prize and the Scientific Breakthrough Award, and is called the god of clouds by people in China.

And the few people sitting next to him are not simple, they are all from the golden generation of mathematics at Beijing University.

Zhu Wen, Xu Yang, etc., were once named "gods" in China.

And the person who talked to Yun Wei was Zhu Wen.

Hearing Yun Wei's answer, he said helplessly, "I'm asking you what you think of the idea of the Galois Domain. ”

云伟沉默半晌，而后说道：“应该会是一个充满特色的新方法。 ”

"But I haven't done much research on this, so I'm not good at commenting."

"But you know what this person has proven the Hail conjecture, and who knows what he thinks?"

Zhu Wen fell silent.

Compared with Li Mu, they are all one round older.

Seeing that such a young genius appeared in the country again, their hearts were full of different emotions.

……

The people in the audience had different ideas, some looked forward to it, and some sighed.

But none of this affected Li Mu on stage.

The first little blackboard was already filled with it.

Then he began to continue the derivation on the second small blackboard.

The narration did not stop at all.

But at the same time, the computer in mind, which is still in the ultimate state of overclocking, continues to deduce at the same time.

Acting out the surprise he had just discovered.

It was this surprise that caused him to pause for almost 20 seconds before his speech began.

As for this surprise, it is a step further than proving the twin prime conjecture.

It made his heart feel surging.

Of course, the surge he felt came from this further surprise, and the surging feeling of the audience came from what he was currently writing.

The second blackboard was written again, and at this point, the two small blackboards on the stage were finished.

And Zhang Yitang, who was sitting in the first row, had already sat up straight.

"This is his method...... This method...... Can it still be written like this? ”

When the person next to him saw his performance, he couldn't help asking, "Professor Zhang, what's wrong?" ”

But Zhang Yitang didn't answer, he kept making the following deductions in his mind according to what Li Mu had written, but he helplessly found that he could not push back after five steps of pushing with his ability.

He urgently needed to know how Li Mu was going to deduce.

But Li Mu on the stage, it seems that the blackboard is not enough at this time?

He just wanted to beckon the staff next to him to push a few more small blackboards, but someone had already shouted before him.

Qiu Chengtong said: "Go get a few more blackboards, hurry up." ”

The staff at the scene are basically student volunteers, and when they saw this big guy talking, of course they didn't hesitate, so they quickly ran into the backstage and dragged two small blackboards up.

Lian Zhengxing frowned when he saw this, his own students were commanded by this surnamed Qiu.

However, seeing what Li Mu wrote on the stage, he still gave up the entanglement.

He could see that Li Mu had written the key point.

And sure enough, as he expected, when Li Mu continued to write on the two new blackboards, in less than 10 steps, many mathematicians in the first row immediately opened their eyes.

"This ......"

They all muttered.

And Zhang Yitang's body suddenly relaxed, and he leaned back on the back of the seat.

"It's a surprise......
