I can't hide it from everyone!

Chapter 21 Unlock
Du Yun picked up the pen in his hand and began to think, staring at the question in front of him.

The problem was no longer something ordinary high school students could solve, but for Du Yun, the difficulty was not as terrible as imagined.

Following the train of thought, Du Yun's arm was already sliding on the blackboard, and clear and smooth problem-solving steps gradually appeared on the blackboard. If a student or teacher with some attainments in mathematics sees the beautiful formulas on the blackboard, he may not be able to help but Nodding in amazement, both the relevant steps and the theoretical basis are perfect.

But the questions are still not like the usual high school math questions. This has already involved university research. Du Yun couldn't solve the answer to this question in a short time. There are three big blackboards in front of him. In half an hour, I only answered the tip of the iceberg. If I want to completely answer the answer to this question, I am afraid it will take a whole day.

But Du Yun was not in a hurry, this question aroused his interest in mathematics.

The tired body and spirit were completely washed away, and the state of the whole person was completely different from before. He was concentrating on the topic in front of him, until two hours later, when the lunch break was over, Du Yun's cell phone rang, and Jiang Tianhao on the phone called After going to the assembly, I reluctantly left the classroom. Before leaving, I picked up my mobile phone and took a photo of the blackboard.

Du Yun, who returned to the meeting point, had no idea how big a wave his steps would cause throughout Tsinghua University!
Du Yun, who walked to the meeting point, still had that question in his mind.

Jiang Tianhao didn't say much when he saw Du Yun's pensive expression. The fact that he could show this expression had refreshed Jiang Tianhao's outlook. You know, Du Yun always looks that casual. There is no serious time when he can let Jiang Tianhao There were very few things that she was so immersed in. If time hadn't allowed, Jiang Tianhao would have wanted to go up and ask himself what this precious student was thinking about.

Zhou Hua took these students to the gathering place, which has ample seats, wide space, and the most high-tech teaching applications. It can be said that as long as it is the most advanced teaching equipment in the classroom, you can see it here.

There were several students standing there on the podium, and they should be students from Tsinghua University.

After Zhou Hua arranged for the students to sit down, he walked to the front of the stage to introduce.

"I am the person in charge of this summer camp. In the future, if you have any questions, you can just come and ask me. These are the seniors who were selected for the previous summer camp and were directly admitted without admission. They will help you To answer some confusion, you can come up and communicate, it’s fine.”

After speaking, the students in front of the stage began to introduce their identities. These people are basically the best in each province, the best of the best, and some of them are students from Du Yun's province.

The students who participated in the summer camp activities came to the stage one after another to ask questions.

But Du Yun didn't care about it, he didn't know where to take out a pen and paper, and started to answer the formula written in the phone at that time, completely unaware of the passage of time, Jiang Tianhao who was not far away saw Du Yun writing Looking at things, he walked behind him to check. When he saw the blackboard title and formula of Du Yun's mobile phone photo, his pupils couldn't help dilating!
The whole person looked extremely excited!It even smells of fear in it!

Isn't this topic just a scientific research question recently raised in the mathematics circle these days? Jiang Tianhao also came across this topic a few days ago and found that this topic was not the direction of his research, and he didn't understand it in depth, but he still wanted to solve the problem. remember.

But Du Yun in front of him actually wrote the steps to solve this problem, and he was very focused. Even when he was standing behind him, he didn't notice this concentration. Moreover, Jiang Tianhao discovered that the steps to solve the problem written by Du Yun had not been solved until now. Hundreds of lines seemed correct to him at first glance!

Du Yun is a high school student!Can you start to deal with this kind of scientific research topic? !

You must know that none of his postgraduate students may be able to understand the question stems!Let alone start answering questions.

When a person is focused, he cannot feel the rapid passage of time around him. Du Yun is now at this stage. He is immersed in the world of mathematics and is completely free from outside influences.

An hour later, Zhou Hua came to Jiang Tianhao's side and wanted to inform the teacher that the explanation meeting was over and it was time to go to the next place, but before he could say anything, he was stopped by Jiang Tianhao.

"Look at the formula written by Du Yun."

Jiang Tianhao pointed to the problem-solving steps on Du Yun's paper, with the same expression as Jiang Tianhao just now. Zhou Hua opened his mouth wide and squinted his eyes tightly, staring at the formula on the paper!
Others may not know the meaning of this question, but he knows it all!
Because his subject this year is to study this problem, and he plans to break through this problem in the next two years. Last time he went to country M to study and investigate, he was looking for a solution to this problem. train of thought, but until now, there have been several trains of thought that have been denied!
He never expected to see someone who could answer this question today, and there is no loophole in either the thinking or the process until now!
He even did not expect that the answer to this question was actually a high school student.

"Teacher, teacher, Teacher Zhou Hua, it's time for the next procedure."

Zhou Hua's assistant stepped forward to ask, but Zhou Hua directly refused.

"You take these students to the next location, and inform the Academic Affairs Office that the teaching rights of this classroom today will be transferred to me!"

Zhou Hua knew very well what it would mean if Du Yun really solved this problem!
The answer to this formula has epoch-making significance for China's national defense missile research!

A physical formula in it needs to be explained by relying on this answer. As long as you can solve this question, you will be a hero of the times!

But Du Yun didn't think too much about it. He just thought this question was interesting, so he chose to do it.

But at this moment, in the classroom that Du Yun took just now, another slovenly and slovenly old man walked in from the door and came to the blackboard. When he saw the chalk writing on the blackboard, his hands trembled and he dared not Believe it!
This person is the 'lunatic' professor that Zhou Hua said just now, and he is also the leader of this branch of mathematics for this question!He is Zhou Hua's boss and leader.

The idea of ​​solving the problem on the blackboard made him suddenly enlightened!

"That's right, that's it! A genius! Who wrote the prerequisites for this question! What a fucking genius!"

The crazy teacher shouted excitedly, picked up the chalk, and started writing his own process directly after the problem-solving steps written by Du Yun.

Everything is difficult at the beginning, especially in mathematics!As long as there is a beginning!Everything will be easier!
