In the end, Xu Yerong still pushed open the door of the math club.

She made a bet with the president of the math club, and if she wins, the math club will be under her control, and if she loses, she will quit the math club.

Because she is good-looking, after entering the math club, those boys all revolved around her and snubbed the female president, so the other party had such a big temper and had to drive her away.

This made Xu Yerong feel very aggrieved, and in order to fight for her breath, she agreed to the female president's bet.

But now, obviously, it's going to lose.

When Xu Yerong entered the math club, the room was quiet at the moment, and everyone looked at her with some pity.

Calling at Senior Sister An Lei, this freshman who doesn't understand anything is really going to be unlucky.

An Lei is the female president, although she is also very beautiful, but compared with Xu Yerong, she is a notch worse.

She snorted proudly with a sneer on her face: "Xu Xuemei, today is the time for you to hand over the four-color conjecture, I think you shouldn't have forgotten the previous bet, right?"

Xu Yerong bit her red lip, glanced at An Lei weakly and said, "Senior sister, can you be accommodating, I feel like I'm still ·····"

Before she finished her words, she was suddenly ridiculed by the girls behind An Lei.

"It's also accommodating, it's been a few days, it's not okay, it's not okay, don't waste everyone's time. ”

"Really, I think she just can't afford to lose, who does she think she is, what qualifications do she have to prove the four-color conjecture, even Senior Sister An Lei can't prove it, she is the oldest. ”

"It's a miracle that someone from the Department of Archaeology joined us. ”

After Xu Yerong heard the ridicule, her aggrieved eyes suddenly turned red.

She clenched her fists and said angrily, "You bully people." ”

Since she was a child, when has she been bullied by others like this, she has a gentle personality, so many people usually like her, but they don't understand why the senior sister in front of her is targeting her everywhere.

When the many male compatriots present saw this scene, they suddenly felt a little unbearable.

But they all knew that if they said a word for the cute girl in front of them, they would probably be expelled from the math club.

This girl offended An Lei and was made difficult by her, and it seems that she is destined to get out of the house today.

It's a pity that such a beautiful girl was driven away to be honest.

An Lei sneered and said, "What about bullying you, we don't have time to entangle you more, now I'll ask you a question, has your four-color conjecture been completed?"

Xu Yerong originally wanted to say no, but looking at the sneering appearance of these people in front of her, she suddenly became even more angry.

Thinking of the time when she was packing her bag just now, Yang Tianjian stuffed the messy four-color conjecture he had argued into her bag.

Therefore, Xu Yerong gritted her teeth and said firmly: "I'm done." ”

In a word, everyone immediately glanced at Xu Yerong.

The argument that can complete the four-color conjecture, whether it is right or wrong, is a great existence.

An Lei sneered: "We agreed very well a few days ago, as long as your argument is successful, I can give you the position of president of the mathematics club, otherwise, you will have to leave, and now, you will take out the conjecture of your argument for everyone to see." ”

"This ·······"

Xu Yerong hesitated, Yang Tian's argumentation method did not start the argument in the direction of the arguments of those professors of Peking University at all, it was definitely a wrong argument, and it would definitely be ridiculed if it was taken out.

But now there is no other way.

She took out the argumentation method that Yang Tian gave her that she thought was wrong.

At this time, An Lei stepped forward and snatched it over.

She looked at the blank paper for the first time, and said with a disdainful smile: "Senior sister, what you write on the blank paper is not at all the direction of argumentation that we are familiar with, do you think you can fool me by scribbling it randomly?"

As he spoke, he directly rubbed the white paper and threw it out of the window.

"The argument failed, according to the agreement we made at the beginning, you lose, you have to get out of here, get out of here now. ”

Xu Yerong's delicate body trembled, her tears could no longer be stopped, and she was aggrieved.

At this moment, downstairs in the Mathematics Society, Professor Yan Ming was walking downstairs from the Mathematics Club at the moment.

He is a professor in the Department of Mathematics.

Yan Ming was very proud today, because when he explored the four-color conjecture, he had already completed nine-tenths of the way, and he was only one step away from completing the argument.

When the time comes, he will be able to make a name for himself all over the world.

However, just as he was about to go back and continue the argument, a ball of paper happened to fall on his head.

Although the paper ball was not painful, it made Professor Yan Ming's face turn blue with anger.

He was a grumpy, and seeing the paper ball held like this, it must have been some student upstairs who littered, or just thought he came over and smashed it again.

He looked upstairs with a paper ball and shouted angrily: "Which stinky boy smashed it, stand up for me." ”

However, An Lei was so far away from the window, plus it was the second floor, how could she hear it.

"No one admits it, right, when I find the evidence, I'll let you write a review. ”

Yan Mingqi's face was ugly.

Annoyed, he opened the paper ball, accidentally tearing some of it in the process.

Yan Ming didn't care, he wanted to find evidence on this, but when he saw that what was written on it turned out to be a four-color conjecture argumentation method, he was stunned.

"What student is so self-motivated that he started to study this. ”

Yan Ming was suddenly happy, forgetting the unpleasantness just now.

He flattened the paper ball, and then said to himself: "Okay, it's fate to meet, so I'll point you to the four-color conjecture how to argue." ”

Yan Ming is qualified to speak like this, he is the most famous professor in the Department of Mathematics of Peking University, even if you look at the whole country, there are only a handful, and you can rank in the world.

Then there is the four-color conjecture that has plagued him for decades, and he has studied it for decades, and now it is time to break through the next difficulty.

As long as there is a breakthrough, the four-color conjecture can be fully demonstrated, and when the time comes, the Nobel Prize beckons.

Moreover, in China, there is no one who understands the four-color conjecture better than him.

Therefore, when he said that he wanted to give pointers, he was definitely not talking big.

When Yan Ming saw the method of initial argumentation written on the paper ball, he immediately became angry.

"It's nonsense, how can the four-color conjecture be so argumentative?"

said it, Yan Ming is a fiery temper, and when he saw this, he was so angry that he almost wanted to tear the paper ball directly.

However, in the end, I still wanted to point out the reason for my shortcomings, so I couldn't help tearing it apart.

He snorted and said a little arrogantly: "It looks like a kid who went astray from the beginning, don't worry, the teacher will guide you how to argue, after all, I am the first person who is about to uncover the four-color conjecture puzzle." ”

Yan Ming continued to look down with a judgmental eye.

"Hey, how can you argue like that? Strange way of arguing, it feels a little stupid. ”

Yan Ming was amazed, and then judged this argument as useless.

"It's better for my argument to be concise and clear, no, this student has fallen into too deep a wrong misunderstanding, and I will definitely pull him up. ”

After thinking of this, Yan Ming was in a good mood, but continued to look.

However, the more he looked down, the more cold sweat appeared on his forehead, and his whole body couldn't stop shaking.

The expression on his face was ever-changing, at first frowning, then suddenly brightened, then amazed, and finally shocked.

"Oh my God, oh my God, oh my God!"

After looking at the discarded paper ball that was casually thrown by others, Yan Ming's face had a hint of horror.

"It turns out that the four-color conjecture was proved in this way, wrong, wrong, all wrong, all my thirty years of hard work have come to naught, and the four-color conjecture has already been proven, hahaha, I still want to point out others? ridiculous, ridiculous!"

Professor Yan Ming cried for a while and laughed for a while, as if he was a ghost, his whole body was trembling with excitement, and his face was full of shock.

"Who is the owner of this paper ball? Who has such terrifying intelligence, and every answer is impeccable, why would he throw away such a precious paper ball? Doesn't he know that this paper ball can make him the number one in mathematics?"

Yan Ming was puzzled, and he didn't know why he wanted to break his scalp.

"No, I must find him, this kind of giant in the world of mathematics is lucky enough to meet him in order to live in vain. ”

Yan Ming, who had made up his mind, quickly memorized the few rooms upstairs with windows open, and then quickly went upstairs. 、

Xu Yerong walked out of the room of the math club with a bitter face, tears on her face, and her eyes were red and swollen.

Her pretty face was full of grievances, she really liked mathematics, but An Lei targeted her everywhere, and she just said ugly things to humiliate her, which made her sad to death······
