After binding the system, Mrs. Wei went down the mountain

The exam begins and test papers are distributed.

In the examination room, you can hear a needle drop.

Those who can sit here and take the exam are all the elites of Beijing University. As soon as the exam begins, all the students lower their heads and start answering the test papers.

There are only four major questions on the test paper, which respectively correspond to the analysis of extremely difficult mathematical formulas such as Euler's formula and the mass-energy equation.

High school mathematics cannot touch these contents at all. The significance of the Peking University exam is to select the real geniuses from these talented students!

Although Zhuo Ran is a little paranoid, she really works hard in mathematics. She has tried to solve three of the four world problems.

One test paper and eight answer sheets of the same size are enough to show how difficult these four questions are.

Zhuo Ran felt some pain in his wrist when he was halfway through writing the first question, so he simply put down his pen and relaxed. Behind him, Ouyang Nai passed by him holding the test paper.

Zhuoran's eyes widened instantly.

No, in such a short period of time, she didn't even finish answering a single question. How could she finish it?

Yes, even for a plenary session, it would take more than an hour to write. How could it be finished in such a short time?

Ouyang Nai definitely didn't know any of the four questions, so he submitted the paper in advance.

As if he knew what Zhuo Ran was thinking, Ouyang Nai tilted the test paper and twisted it with his fingers. Several answer sheets unfolded like fans, and each sheet was filled with mathematical formulas.

Zhuoran's lips trembled instantly, and the hand holding the pen kept trembling.

In just ten seconds, Zhuoran's expression changed again and again.

"No, no, no."

Ouyang Nai handed the test paper to the front and was about to go out.

"Classmate, are you sure you want to hand in your paper?"

"Yes, teacher, I remember you can hand in papers in advance, right?"

The teacher glanced at Ouyang Nai. At first, he had the same idea as Zhuo Ran, thinking that the question was too difficult. But when he saw the full answers, he was stunned.

The teacher took a look at the name on the test paper. It was Ouyang Nai, the number one freshman this time.

"Classmate Ouyang, please wait a moment."

"Teacher Gu, what's wrong?"

There are two invigilators in each classroom, one in the front and one in the back. The teacher at the back saw that something seemed to be happening in the front and stepped forward to ask about the situation.

"Teacher Zhang, please take a look first. I have something to do and will be right back."

Ouyang Nai saw the invigilator leaving quickly with his test paper and said from behind:

"Teacher, hurry up, I have to go home and cook later!"

The school office building, inside the math group office.

An old man with fluffy hair and gray beard was studying a mathematical problem on the blackboard. The entire blackboard was filled with formulas. The old man frowned, glanced at the teachers in the office, and asked in a deep voice:

"Which one of you has an idea?"

Several teachers wanted to bury their heads under their desks.

When the old man saw this, he snorted coldly.

"Both of them are useless guys!"

The teachers are afraid to show off their arrogance. Professor Wang is a famous math madman in the school. The math problems he studies are all world-wide problems. They really don’t know how to do it. No, no, no, they really don’t have any ideas at all. ah!

Just when the atmosphere in the office was very quiet, there was a rapid knock on the door.

"Please come in"

Teacher Gu, the invigilator, came in with the test paper. Before he could say anything, a teacher in the office asked curiously:

"Hey, Teacher Gu, aren't you the invigilator for today's math competition? Why are you free to come to our math group?"

Teacher Gu wiped the sweat from his forehead and ran all the way from the exam room. He was already out of breath from exhaustion.

"Stop talking about this now, Professor Wang, please come over quickly and see if this child's answer is correct."

Teacher Gu handed over the paper.

One of the teachers took it and said with a smile:

"Teacher Gu, you can really joke. The exam has only started for more than half an hour. Do you want to tell me that students have already handed in papers at this time?"

As soon as the teacher finished speaking, he was stunned.

Teacher Gu was still there and said:

"Originally I didn't want to come here, but this candidate is the student who scored first in the freshman exam. I don't know much about mathematics, so I quickly showed it to you. I asked her to wait outside the examination room. "

"Teacher Wu, what's wrong with you?"

Teacher Wu was the one who took the test paper just now. His eyes widened and he carefully examined the eight large pieces of paper.

"Oh my God! Professor Wang, come and see!"

"Both the first two questions are correct, and the problem-solving ideas are thorough and clear. There are even two solutions for the second question. As for the last two questions, I am not very clear."

Stabilizing his emotions, Teacher Wu quickly said:

Hearing this, the old man who was at the blackboard just now appeared directly next to Teacher Wu a moment later, grabbed the paper, and looked at it carefully with his glasses on.

"Okay! Good answer!"

"It turns out that this question can be argued from here!"

When he saw the last question, the old man's face suddenly became serious. He walked to the blackboard with the paper in hand, erased all the formulas just now, and began to argue again according to the ideas on the test paper.

A few minutes later.

The old man looked surprised.

"This is indeed right, genius!"

When the old man was enjoying himself alone, Teacher Gu suddenly said:

"Professor Wang, that child is still waiting outside the examination room. If she is not answering blindly, I will let her go first."

"Ouch, it's such a strong wind."

"Did you forget to close the window?"

"Hey, where is Professor Wang?"

Teacher Gu looked up and saw that Professor Wang had gone out at some point.

After looking at the time, twenty minutes had passed. Ouyang Nai sighed and was about to leave when he saw an old man staring at him furtively.

Ouyang Nai twitched the corners of his mouth and turned his back.

Unexpectedly, the old man came over directly and took out a paper.

"Little girl, did you write this paper?"

Ouyang Nai took a look and saw that it was indeed the test paper he had just written.

So he nodded and said:

"I wrote it, just finished it, freshly baked."

The old man suddenly became excited and laughed loudly:

"Genius, hahaha, little girl, how about becoming my teacher?"

Ouyang Nai glanced at the strange old man who suddenly appeared and shook his head in rejection.

"I already have a master."

"Who is your master?"

The old man suddenly became serious, stared and asked:

"It doesn't matter who my master is to you. I'm telling you, old man, it's going to be noon soon. I have to go back to cook. Bye."

After saying that, Ouyang Nai turned around and left.

If I keep struggling with this old man, I may not know when I can go back.

"Hey, little girl, come back here, haven't I finished saying this?"
