And just when Xu Yerong came out, Professor Yan Ming also happened to go upstairs.

When Xu Yerong rubbed her red beautiful eyes and saw that what Yan Ming was holding turned out to be the four-color conjecture argumentation method written by Yang Tian, she was stunned.

"How could Yang Tian's four-color conjecture argumentation method be in Teacher Yan's hands?"

Xu Yerong was confused.

Looking at the ecstatic look on Professor Yan Ming's face, it seemed that he had encountered something happy.

"Could it be related to the four-color conjecture written by Yang Tian?"

Xu Yerong hurriedly followed Yan Ming.

"It must have been thrown out of the window of the math club. ”

Yan Ming looked at the flawless method of the argumentation again, with a smile on his face.

Excitedly, he pushed open the door, took the ball of paper and asked loudly, "Who threw this?"

The group of people in the math club were still flattering An Lei, saying that he defeated Xu Yerong without much effort.

Just as they were triumphant, the door was pushed open, and a loud shout came from outside.

When looking at the paper ball that Professor Yan Ming was holding, everyone's eyes were on An Lei.

"You threw it?"

Yan Ming stepped forward and asked.

"No, no, I didn't throw it. ”

An Lei's little face turned a little pale with fright, she knew that Professor Yan Ming was very strict in the entire Peking University Mansion, and his temper was also hot, and he had reprimanded female students to cry more than once.

Looking like this, it was obvious that when he was passing by, this ball of paper accidentally hit him.

Yan Mingyu asked, "Is it you or not, tell me quickly." ”

Under his scolding, An Lei was so frightened that her body shook, and then her face turned pale and said, "Teacher Yan, I didn't mean to, can you spare me." ”

Yan Ming grabbed An Lei excitedly and said: "Classmate, hurry up, tell me how you proved the four-color conjecture, after the proof came out, why did you throw it away without pity? ”

"What?"

When everyone saw this, they felt like they were going crazy.

When did An Lei prove the four-color conjecture? If she could, she wouldn't throw it unless she was stupid.

Also, Yan Ming's last sentence simply made everyone start to doubt life.

A full-fledged professor at Peking University, an honorary deputy director of the mathematics community, and a mathematics giant who can be ranked among the top 10 in the country, even said that he wanted to ask An Lei a question.

If this spreads, it will definitely surprise everyone.

An Lei was also stupid, looking at the paper ball that Yan Ming was holding in her hand that she had just thrown away like waste paper, and seemed to think of something.

"Is it ········ The four-color conjecture that the little girl took out turned out to be correct?"

An Lei was taken aback by this thought, but with Yan Ming's high status in front of her, she would definitely not use this to fool her.

Moreover, looking at Xu Yerong's little girl's appearance, she obviously doesn't know what the things written on this piece of paper represent, so to speak, all these honors and credits are hers, becoming a new star in the mathematical world, comparable to the genius girl Su Shirou who cracked Goldbach's conjecture in Tsinghua University,

Then, he won the Fields Medal in one fell swoop, gained the attention of the world mathematical community, and thus became an upper-class elite.

At the thought of this, An Lei almost suffocated in ecstasy.

She hurriedly said excitedly: "That's right, Mr. Yan, this is what I threw it, I didn't expect this small paper ball to alarm you." ”

Professor Yan Ming laughed and said: "Fortunately, it alarmed me, looking at you like this, obviously I don't know that my argument has succeeded, classmate, I am honored to tell you now that you have successfully cracked the four-color conjecture, and you are the first person in the world to crack the four-color conjecture."

An Lei nodded excitedly.

The people on the side had a strange look on their faces.

An Lei is not qualified to be the first person, she is very jealous, and the position of president of the math club is still forced away by despicable means.

Moreover, this paper ball seems to have been brought by the previous schoolgirl named Xu Yerong.

It's just that An Lei seems to have crumpled it up after just one look, and then threw it out of the window.

It would be despicable to admit that she had written the contents of this paper ball.

Professor Yan Ming said excitedly: "You are ready to prepare, I will call all the math bigwigs in the capital now, and then make public the method you demonstrate, all this glory belongs to you, and when I contact the world, the Fields Medal, the biggest award in the mathematics world, is also yours." ”

An Lei nodded excitedly and said, "Then thank you, Professor Yan Ming." ”

Now she seems to see her rising star in the future.

And at this moment, the door was kicked open, followed by a crisp cheer, interrupting all her fantasies.

The four-color conjecture was not her argument, and it had nothing to do with her at all. ”

In a word, everyone's attention was concentrated.

When they saw Xu Yerong coming, those students who were already unhappy in their hearts immediately breathed a sigh of relief.

All this glory is all girl's, and An Lei is not qualified to snatch it.

After Professor Yan Ming heard Xu Yerong's words, he was stunned at first, then looked at Xu Yerong, and then at An Lei.

Seeing that Professor Yan Ming was looking at him suspiciously, An Lei suddenly seemed to be fried, and said viciously at Xu Yerong: "Little hoof, what nonsense are you talking about? The four-color conjecture was originally my argument, where did you come from to dare to mess around here, what are you still doing in a daze, why don't you hurry up and kick her out for me." ”

An Lei's face was hideous, angry, and she looked very murderous.

And the two little sisters behind him nodded after hearing the order, and then came towards Xu Yerong.

They have big shoulders and round waists, and Xu Yerong feels that her petite body can't beat them at all.

She was angry, and cried out again angrily, looked at Professor Yan Ming and said, "Professor, this piece of paper is mine, she thought the argument was wrong after looking at it, and then crumpled it up and threw it out." ”

Seeing this, Yan Ming looked at An Lei suspiciously, and then shouted angrily at the two little sisters with big shoulders and round waists: "Stop." ”

He took the piece of paper and said in a somewhat cold tone: "Whose is this four-color conjecture argument?"

"It's mine. ”

An Lei and Xu Yerong spoke in unison.

Originally, this worthless paper ball, but after it was confirmed, it became a fragrant dumpling.

Even the onlookers wanted to scramble.

Yan Ming's face suddenly turned cold.

"Whose the hell is it?"

He said, "If you can write such an amazing argument, will it be these students in front of you?"

You know, he has been researching for his own time, but he is older than all of them.

Until now, An Lei is still a dead duck and said: "I wrote it, and I threw it out." ”

Yan Ming glanced at An Lei and sneered: "You said that you wrote it, then you can list the formula for me in the penultimate line, and then explain it carefully." ”

"This ······"

An Lei's face suddenly turned pale, she only looked at the front two lines in front of her, and she didn't look at the back at all, now that she thinks about it, her intestines are repentant.

Yan Ming snorted angrily, and then looked at Xu Yerong

Xu Yerong was taken aback for a moment, and then told the truth: "Professor, this is what a friend of mine gave me to argue, he said that the argument was successful but I didn't believe it, this piece of paper was really taken out of my bag, if you don't believe it, the person next to me can also testify." ”

Under Yan Ming's majestic gaze, everyone nodded their heads again and again.

Yan Ming finally breathed a sigh of relief, and then said expectantly: "Then where is he now? Is it convenient? I want to see him now?"

Xu Yerong nodded, and then said weakly: "Teacher Yan Ming, you wait for me first, and after I deal with the matter, I will take you to him." ”

As she spoke, she snorted coquettishly and walked to An Lei's side triumphantly like a little hen.

She wiped her tears, although her eyes were still red, but there was excitement in her beautiful eyes.

Xu Yerong sniffed, looked at An Lei and said, "Now, if you lose, then according to the agreement, you leave the math club, and the position of president is mine." ”

"No, you can't do that. ”

An Lei was remorseful, looked at Xu Yerong and said, "Senior sister, I was wrong, how about we end this matter, I won't drive you away again." ”

was exposed to lies, and was kicked out of the math club by a first-year student, if this spreads, she will have no face to go to school in the mansion of Peking University.

How could Xu Yerong be soft-hearted, when she was crying just now, when she was kicked out, the other party didn't have any mercy.

She smiled, and just when An Lei thought she agreed, she only heard Xu Yerong slowly speak: "You are dreaming." ”

The words fell, and he looked at the people around him excitedly: "From today on, I will be your president, and the first thing I have to do now is to drive her out." ”

As he spoke, his slender jade fingers pointed at An Lei.
