Facing the clamoring Lin Yujing, Li Zheng just smiled.

How could a child like me understand my current state?

Her thinking is still limited to shortcuts and minimalist solutions.

Although the talent is outstanding, this is still only the first level——

Use formulas.

The second level is to forget the formula.

Let your mind travel freely, freely navigate between images and equations, and solve problems elegantly.

Perhaps Lin Yujing has reached this level through seclusion and practice.

But it doesn't matter.

Because Li Zheng is already on the third floor.

After nearly a thousand hours of hard work, he has weaved mathematics and physics into a large web.

In this large mathematical network, he can travel to any point like an electric current.

The heavy sword has no edge, and the sword has no moves.

This is the way to win without any tricks in the world of mathematics——

No formula is better than having a formula.

This realm is lonely.

Because it cannot be described, others cannot understand it.

Li Zheng looked at Lin Yujing who was moving forward proudly, and also felt a sense of loneliness.

After this loneliness, I actually felt a burst of envy.

Student spirit, girlish frivolity.

So naive, so ignorant.

How good, how happy.

Seeing Li Zheng's father-like smile, Lin Yujing felt very sick.

"The training camp is so silly..." Lin Yujing shook her head, walked straight to her seat, took out a traditional space pencil case and water bottle, and said unhurriedly, "Now, I can understand what Gui Jianfeng said.

"

Li Zheng's eyebrows tightened: "What did he say?"

"It's okay." Lin Yujing narrowed her eyes and looked at Li Zheng, and waved her hand casually, "You don't understand even after I told you, scumbag."

"Haha." Li Zheng was not angry and waved his hand casually, "I'm just a talkative kid."

The two of them shook their heads and entered a state of ignoring the other.

This state lasted until the third biology class.

According to the agreement with Zhu Hongbo, this is the time to go to the mathematics teaching and research group to take mathematics classes.

The two of them were silent all the way until they entered the office, still ignoring each other.

Zhu Hongbo was scheming and knew very well that outsiders should not interfere in the affairs of the two young classmates.

He didn't say much and directly asked the two of them about their progress this week.

Li Zheng replied steadily: "Mathematics has improved slightly."

Lin Yujing replied more steadily: "I can't see the ceiling."

Li Zheng laughed: "I have never seen such a shameless person."

Lin Yujing had daggers in her eyes: "My defeated general still dares to bark in the mathematics office!"

Li Zheng's eyes narrowed: "Find out who is the loser."

Lin Yujing raised his fingers and said: "Whoever loses more will win."

"Okay, okay." Zhu Hongbo was already grinning from ear to ear, "How can we start a quarrel with something as big as this?"

"Teacher Zhu, it's not a quarrel." Li Zheng turned his head and said, "It's just that now, in terms of mathematics, it is difficult for me to have a common language with Lin Yujing."

"Not now." Lin Yujing chuckled and waved her hands, "never."

"Okay." Li Zheng looked stern, "I didn't want to argue with you at first. This was bullying. Now, you have successfully angered me."

After saying this, he turned to Zhu Hongbo: "Let's ask a real math problem, Teacher Zhu."

"Ah..." Zhu Hongbo hesitated, "No need, forget it... With all due respect, Li Zheng, of course you have great potential, but to truly surpass Lin Yujing, especially in the field of top-level problems, you

I’m afraid there’s still a long way to go.”

Lin Yujing nodded, very convinced.

"Stop talking, let's come up with a question." Li Zheng waved his arm and took out his pencil case and scratch paper, "Just in time, I want you to re-evaluate my mathematical ability."

"..." Zhu Hongbo glanced at Lin Yujing, and after the latter blinked mischievously, he said helplessly, "Since you are so determined, then I will give you the question. But there is a saying before, you three

I can't stand the commotion in the world. Just this time, whoever scores higher will be the winner. Don't engage in such competitions again in the future."

"It's the final word, it's exactly what I want."

"Well!"

Looking at the virtues of the two of them, Zhu Hongbo also raised the corners of his mouth.

Student spirit, girlish frivolity.

So naive, so ignorant.

So envious.

but.

Don't think that you can easily handle mathematical problems in physics, just like how strong you are in mathematics.

That's not even the beginning.

"Real mathematics" comes right out of the mouth.

You people who have no respect for mathematics.

It's time to teach him a lesson.

Zhu Hongbo did not go through the question bank at all, but directly raised his hand: "It's just one question. The question is very simple. I just said, you can just write it down."

Li Zheng immediately picked up his pen.

Lin Yujing also hurriedly pulled up a chair, slapped the notebook on the table and prepared to record.

"I'm just going to say it once, please listen to the question." Zhu Hongbo said calmly——

[Please confirm whether there is a positive integer n that satisfies the following conditions:]

[n is exactly divisible by 2000 different prime numbers.]

[And 2 raised to the nth power, plus one, is divisible by n.]

Zhu Hongbo paused for a moment and laughed when he saw the two of them staring blankly at the topic they had just written.

"That's it, you don't have to force yourself to do it." Zhu Hongbo glanced at the wall clock and said, "It's five minutes to 10 o'clock. I'll give you two hours to do it until 12 o'clock. You can give up halfway. I will explain the ideas to you.

.”

After saying that, he pulled over two large stacks of papers and started marking the homework.

On the other side, Lin Yujing and Li Zheng glanced at each other almost at the same time.

After noticing the other party's sneak peek, he lowered his head in panic and looked at his roll.

And I felt a little calmer——

【Fortunately, she (he) is also confused.】

Since the other party was also confused, he was not so panicked.

Li Zheng re-examined the question.

Very good. Isn't this kind of question that does not rely on formulas and theorems our own advantage?

The web of mathematics and physics unfolds!

Math Brain, start up!

There is no trick to win without a trick!

5 minutes later.

Smoke rose from Li Zheng's head and the machine went down.

Fuck your math brain.

Fuck you math network.
