Seeing this, Yechen was not annoyed: "Then, what if I don't leave?"

Xia Yuanyuan looked at the little kid in front of her, who looked very immature, and thought to herself that this person was actually a scoundrel, but no matter how she said it, she was also the administrator here, so it was impossible to let him in casually, right?

So she said, "If you don't go, you can stand here, and of course you can sit next to you, but I don't have free coffee here." ”

Yechen also said pitifully when she heard Xia Yuanyuan's resolute tone: "Sister Yuanyuan, you see that I still came here on Saturday, I must be a good student, anyway, I have nowhere to go now, otherwise, you can take me in, right?"

"It's really not good, you can let me study with you next to you. ”

Xia Yuanyuan looked at Ye Chen with wide eyes, she didn't answer Ye Chen's words, but asked rhetorically, "How do you know my name??"

Yechen replied casually: "Ao, you said this, I just saw what you saw from your test paper when you did the question." ”

"You!" Xia Yuanyuan didn't know what to say for a while, this little scoundrel in front of her was good.

Seeing that she couldn't persuade this person to leave, she simply lowered her head and did the question.

But she lowered her head to do the question but couldn't put it down, because she only had this fill-in-the-blank question left in the whole paper and couldn't do it, she was also a competitive character, and this test paper was not simple, but all the rest of her questions were made, and she was obviously a little unwilling to put this question here, but she didn't want to give up just like that.

In fact, she's been sitting here for more than two hours trying to solve this problem, and every time she has a clue to do it, she feels like she can't put pen to paper, or halfway through it, she realizes that her own method is simply wrong.

And most importantly, when she just thought that there was a way to solve this problem, she was coldly interrupted!

And she wanted to take advantage of the fact that there was no one at school on Saturday, so she specially applied for the status of librarian to study here, but she didn't expect to be disturbed, how could she be in a good mood?

But she didn't have much way to vent, because she couldn't get rid of the little kid in front of her no matter what, which made her very distressed, and in desperation, she had to take a ballpoint pen and draw circles on the paper...

Yechen saw Xia Yuanyuan's thoughts at a glance, and immediately felt that this young lady was very cute, so he gently knocked on the table in front of him.

Xia Yuanyuan suddenly looked at Yechen impatiently when she heard the voice and said, "What's the matter with you?!"

Yechen smiled and said, "Hehe, Sister Yuanyuan, if I say I'm a math genius, can you let me in?"

"Don't call me Sister Yuanyuan, I'm not familiar with you, what about math geniuses, it's the school's rule not to enter on Saturdays and weekends! Because it's basically been cleaning in the past two days, and no one can enter unless the principal comes! What about math geniuses, hum!"

Xia Yuanyuan said almost mercilessly.

And what she didn't expect at all was that the words that she felt were too excessive and hurtful in her heart were surprisingly pleasing to Yechen's ears, Yechen not only didn't feel annoying, but felt that this young lady was very interesting, and he liked it inexplicably.

So Yechen still smiled and said, "What if the math genius can help you solve this problem?

Hearing Ye Chen say this, Xia Yuanyuan was stunned for a moment, and then looked at Ye Chen with a questioning expression: "Didn't I say you, little brother, please organize the language well before you speak, have you seen it clearly, the test paper I did is an advanced mathematics question, which is more than one grade more difficult than the knowledge you are learning in high school now, even if you are a genius, it is impossible for you to understand the high-level knowledge of the university." ”

"And, if you really want to help me, please don't talk and play for the time being, so that I can sort out my thoughts well, and maybe I can really make this problem." ”

Yechen heard Xia Yuanyuan say this, but did not speak, but walked around the table to Xia Yuanyuan, picked up a pen and a piece of paper and wrote directly.

Xia Yuanyuan wanted to stop it, but when she saw that this little kid picked up the pen and started writing, she didn't do anything, but sat on the chair with her hands on her chest and looked at Yechen with a serious face.

She wanted to see how the megalomaniac was going to help her solve this question.

Almost without thinking, Yechen quickly wrote down the answer line by line on the paper.

It took almost less than ten seconds for Yechen to stop writing, and then put the pen in his hand aside.

"Finished writing?" Xia Yuanyuan said with a puzzled expression.

"Yes, I can do such a simple question almost without thinking about it, okay?" Ye Chen said proudly.

"Really?"

Xia Yuanyuan said and took the paper that Yechen had solved the problem on.

She first glanced at it casually, and found that the whole paper was densely packed with more than a dozen lines of numbers, and these numbers and mathematical symbols were all too familiar to her now.

But Rao is like this, Xia Yuanyuan's first reaction is still not convinced, the little kid in front of her is really a mathematical genius as he said, and even if he is a mathematical genius, it is impossible to solve the problem so quickly without even reading it, right?

So she glanced at Yechen suspiciously, but Yechen whistled and raised her head slightly to signal her to continue.

Xia Yuanyuan also glanced at Yechen, and then continued to look at Yechen's problem-solving steps.

But then, when Xia Yuanyuan looked at the solution ideas line by line, the doubts and disdain on her original face were almost all transformed into incredible and shocking!

So much so that her hand holding the paper trembled slightly, she couldn't believe that this was something that a high school student could solve.

Because Yechen's method of solving the problem is not only novel, but also unique, it is completely different from what she usually listens to the teacher in college, but she knows that Yechen's thinking is completely correct, and the final answer is no different from the standard answer, so that she suddenly has a feeling of enlightenment when she reads it.

She now has a feeling of being slapped in the face, she just looked at the little kid in front of her with contempt in her eyes, she didn't expect that this little kid can easily solve the problem that she racked her brains can't solve.

Xia Yuanyuan knew that this question was the finale of the entire test paper, and if she wanted to solve this question easily, she must reach the elite level of her former university, or even the level of a professor!

And if the little kid in front of her is really like what she imagined, it will be a little scary.
