Liu Yiyi flattened her mouth and walked to her seat.

She didn't believe it, with Teacher Fei Fei in front, what else could Yechen do to her.

And when she walked to Yechen's side, she heard a vague voice floating from Yechen's mouth: "Little drama spirit......"

It made her angry again.

So she deliberately slapped Yechen hard with her elbow.

Yechen's rough-skinned and thick-fleshed Liu Yiyi felt to him that it was actually no different from tickling.

After Liu Yiyi walked to the seat, she turned her head directly and ignored Yechen, Yechen just smiled when she saw this and didn't speak again.

Soon the class bell rang, and Jiang Feifei also started her formal teaching.

And she didn't rush to class, but mentioned something to Yechen and Qin Fei before class.

That was the homework she assigned to the two of them yesterday, and it was also a difficult problem for the two of them, in fact, Jiang Feifei also knew that unless the two of them asked someone else when they went home, it was almost impossible to make this question.

Jiang Feifei took a look at Qin Fei and Ye Chen, and found that the two of them were confident, without the slightest fear of going into battle.

"It seems that the two of them have been prepared for a long time. ”

Jiang Feifei thought about it and said, "You two, who will go to the blackboard to demonstrate first?"

Before Yechen could speak, Qin Fei stood up and walked to the blackboard.

Yechen also smiled when he saw this, but did not speak.

Qin Fei thought in his heart that this kind of thing would have to be done by him first, because he knew that the difficulty coefficient of this last question was not ordinarily high.

Unless you have some knowledge of the sophomore and junior years of high school, it is impossible to make this question.

And he happened to know this question, or to be precise, he used some small means to force the sophomore to do this question.

Now the solution area of the last question on his test paper is full, and he is naturally full of confidence, and now he only needs to write down the solution steps on the blackboard, so that he can not only get praise from the sexy female teacher on the stage, but also may be favored by Liu Yiyi!

It's a win-win!

Qin Fei strode to the vicinity of the podium, then took out the chalk from the chalk box and smiled politely at Jiang Feifei.

Although Jiang Feifei didn't like Qin Fei's eyes when she looked at her, she still smiled and nodded, and stretched out her hand to make a gesture of invitation.

Then Qin Fei picked up the chalk and quickly wrote on the blackboard according to the answers on the test paper, and soon, Qin Fei wrote all the entire problem-solving steps on the blackboard.

Jiang Feifei glanced at it and nodded approvingly: "Yes, except for the fact that the idea of solving the problem is quite conservative, it is basically right." ”

Qin Fei also grinned when he heard Jiang Feifei's words.

Then he looked at Yechen with disdain, and at the same time didn't forget to use his eyes to discharge wildly at Liu Yiyi.

The look in his eyes was like saying, "I'm done, see how you end up if you kid can't do it later." ”

Yechen didn't even glance at Qin Fei's provocation.

Liu Yiyi naturally saw Qin Fei's eyes on herself, and instantly felt that Qin Fei was extremely disgusting, she didn't have a good impression of Qin Fei in the first place, but she was even more disgusted.

And at this time, she felt that Yechen's image in her heart was much better than Qin Fei's, although Yechen didn't like to study and liked to make her angry, but Yechen's style of doing things was still very regular.

And Liu Yiyi felt very funny about Qin Fei's provocation of Yechen, Yechen could easily write the answer to the entire test paper, and this question had just been completed in front of her, how could she be ugly when she got to the podium.

After Qin Fei got off the podium, Yechen slowly walked onto the stage.

Jiang Feifei also asked in a somewhat uncertain voice when she saw Yechen coming to the stage: "Yechen, do you know how to do this question?" How did I hear Liu Yiyi say that you taught her a lot of questions?"

Yechen also gave Jiang Feifei a reassuring look, signaling that she didn't have to worry, and Jiang Feifei's other question he didn't rush to answer, because the answer would be revealed soon.

And the moment Yechen came to the stage, someone in the audience whispered: "Did you say Yechen is okay?"

"Then who knows, looking at his confident appearance, it should be okay. ”

"I guess so, it's the homework the teacher gave them. ”

"Then who knows, even if he can't, he can let others help like Qin Fei, the two of them have the same virtue, it's normal to do this, I don't believe that Qin Fei did it himself. ”

Qin Fei doesn't care if he hears it, haven't you seen the horror of Ye Chen, if he hears you, I won't be played to death by him!"

Yechen also smiled when he heard the discussion from the audience, it seems that because of Qin Fei's ignorance in the past two days, he has established his prestige in the class.

Then he picked up a random piece of chalk and began to write on the blackboard.

Brush brush brush ~

The grinding sound of chalk swiping across the board is frequent and pleasant.

The neat handwriting and standard problem-solving steps were written little by little, and even Jiang Feifei on the stage was amazed when she saw it.

She thought that Yechen might not know anything and make a fool of it, and when the time came, she wouldn't be able to punish him for copying a hundred times for the sake of fairness, but she didn't expect Yechen to easily write out the solution steps without even looking at the test paper, and there was no deviation, no mistake at all!

Yechen's calm posture and confident expression didn't look like a student in Jiang Feifei's eyes, but more like a mathematician who had experienced a lot of battles!

And Liu Yiyi in the audience looked at Yechen's calm back on the stage, and her eyes were also full of brilliance.

Soon, the standard answer to this question was perfectly presented on the blackboard by Yechen.

Jiang Feifei nodded with great satisfaction.

"Very good, the idea is bold and original, and there is no mistake. ”

Although Jiang Feifei was also surprised in her heart, she also gave a very pertinent evaluation.

And then, Jiang Feifei found that Yechen, who had already written the final answer, did not stop holding the chalk.

Instead, they began to write again in another blank space.

Not only Jiang Feifei, but all the students in the audience were very puzzled by Yechen's actions.

The reason for the puzzle is that this question has been answered, what else does Yechen have to write?

And in the next moment, what Yechen did did not shock the classmates, but greatly surprised Jiang Feifei.

Yechen is actually answering this question with a learning level that does not belong to the current stage of high school students!

Brush tip with a quick stroke.

Jiang Feifei's eyes were full of incredible!

One, two, three...... Five!

At the moment when Yechen finally stopped writing and turned around, Jiang Feifei was so excited that she almost screamed out of shape.

Her eyes widened in disbelief as she looked at the answers written on the blackboard, her eyes filled with shock!

And the reason why Jiang Feifei was so shocked was only known to Yechen and Jiang Feifei.

That is, Yechen actually divided a question into five ways to do it!

And that's not all, the first two of these five methods are acceptable to Jiang Feifei, one is the knowledge of the second year of high school and the other is the knowledge of the third year of high school.

The last three are all very pure university knowledge! Especially the last one, which is the method of solving problems that Jiang Feifei only learned when she was a doctoral student!

At this time, Ye Chen used these methods to make a question that could hardly be described as miraculous in Jiang Feifei's eyes, it was simply a genius!

No, to be more precise, the pillars of the country who are even more geniuses than geniuses!

Jiang Feifei couldn't believe her eyes, she never thought that Yechen, a first-year high school student, would make such a shocking move.

And now she almost no longer feels like a teacher and a student for Yechen, but more like the kind of college classmate relationship that has been reunited for a long time.

Excited and moved.

Although the students in the audience didn't understand the principle of Yechen's next several problem-solving methods, they could probably think that Yechen was solving the same problem based on the same answers.

Liu Yiyi saw the problem solving method on Yechen's blackboard, and the shock in her heart was no less than that of Jiang Feifei on the stage, she could only understand three of these problem-solving ideas, and she couldn't figure out what the principle was even if she racked her brains, and now she was more shocked or hated in Yechen's heart, but worshipped!

Even the girl's heart, which had never wavered, began to throb a little.

Yechen himself didn't have much feeling about the reaction of Jiang Feifei and the people in the audience, because he knew that it was estimated that except for Jiang Feifei, the rest of the people might not be able to understand it at all, but it didn't matter, as long as Jiang Feifei could understand it.

After a while, Jiang Feifei said excitedly: "Yechen, you tell the teacher, where did you get the steps to solve this problem?"

Yechen also replied quite respectfully: "Teacher Hui, I came up with these solutions alone, and there are more than these methods of solving problems, and I didn't write them out just because the blackboard was not enough." ”

"Hiss~"

After hearing this, there was a sudden gasping sound in the air, and Jiang Feifei was no exception.

He has such a talent for mathematics at such a young age, and if he really cultivates it, it will be so terrifying.

This was Jiang Feifei's first thought.

After a short period of excitement, Jiang Feifei glanced at Yechen deeply and said to the class: "Students, please see the steps of Yechen on the blackboard, these methods can be said to be very subtle and profound, you can carefully copy them down and study them slowly after class." ”

At the same time, the teacher was also very surprised by Yechen's mathematical talent, and it is not an exaggeration to say that Yechen is a rare mathematical genius in our school and even in Ping'an County and even the whole of China. ”

As soon as Jiang Feifei's words came out, most of the people in the audience also cast their adoring eyes on Yechen, especially the girls, who threw their unconcealed love to Yechen.

"Brother Chen is so good!"

"Ah Chen, you are so handsome, ahh...hh

"Ah Chen, I'm going to chase you!!"

What's more, those who are close to Yechen are about to climb Yechen and kneel and lick.
