Although Lu Yuxin didn't raise her hand once just now, it doesn't mean that she doesn't think these questions are difficult.

Not only because she thinks this kind of child's game is too childish, but also because the girl is confident that if she is given enough time, she can still solve these problems independently.

Of course, one class is certainly not enough.

But if she can't complete it, it doesn't mean that Wang Yufei can't complete it.

This guy in front of her is a boy worthy of her active pursuit, if she can't even compare, why should she take the initiative to pursue?

Yes, the one who has the most confidence in Wang Yufei in this classroom is Lu Yuxin, and the almost paranoid trust between geniuses is incomprehensible to ordinary people.

......

Wang Yufei took Guo Xiaoyi into the classroom and attracted a lot of attention.

After all, they were the last to enter the classroom.

Many parents are also discussing, parents are still second, Yu Dewei, who was sitting in the last row, saw Wang Yufei walking towards Lu Yuxin with no one in his eyes, and his nose was almost crooked.

He glanced at the couple beside him - Guo Jianfeng and Han Qian.

This is also the most depressed place for Yu Dewei.

If it weren't for the fact that the couple also came today, he couldn't help but want to reprimand Wang Yufei just now. Fortunately, in the end, Guo Xiaoyi sat next to Lu Yuxin, otherwise Yu Dewei might really explode.

However, the teaching director also made up his mind, as long as Wang Yufei couldn't finish these questions today, he had to teach Wang Yufei a lesson. He believes that they are all educators, Guo Jianfeng and Han Qian can also understand him, they are all for the good of the children, right?

And he's confident!

Although he is not very good at mathematics, he can roughly weigh the difficulty, after all, he can't understand the selected topics at all. And he can analyze something from Han Wenle's changing expression......

It's stable today!

......

In the eyes of Guo Jianfeng and Han Qian, when they saw Guo Xiaoyi sitting next to Lu Yuxin, getting along well and talking happily, they couldn't help but exchange a look.

It seems - pretty good?

Anyway, Lu Yuxin is also a very famous genius girl in the first middle school of the provincial capital, and becoming friends with Xueba is not a bad thing in any way, and the communication between peers is much smoother, maybe she can guide Xiaoyi to study in the future?

......

"Okay, everyone, please be quiet, there are five minutes to start the class, and I will say a few words before today's class. ”

"First of all, today's open class is divided into two parts, the first part is the problem solving link, the problem to be solved is just by our 28 students in the Olympiad class of six questions selected by themselves, through voting! As you can see, these questions can be said to represent the highest difficulty of the Olympiad Mathematics Competition, and two of them have appeared in the World Mathematics Olympiad Competition! Other questions are probably of similar difficulty. ”

"The first part of the problem solving time is ...... 40 minutes!" Han Wenle hesitated for a moment, and finally decided to compress his final speech and spare ten more minutes for Wang Yufei.

It was only half an hour, and Han Wenle was afraid that if something went wrong, Wang Yufei really couldn't solve a single question, so he would plant it today......

"Of course, it's not up to me to solve it, but a junior high school student from our high school Olympiad class to solve it, Wang Yufei, come to the podium to say hello to everyone. After speaking, Han Wenle beckoned to Wang Yufei.

All eyes in the classroom immediately focused on the direction of Han Wenle's beckoning, and Wang Yufei, who was standing there, immediately became the center of attention.

A whisper followed.

"He is Wang Yufei?"

"Say it's a junior high school student who entered the class through the back door?"

"It doesn't look like much, does it?"

"What does Mr. Han mean by that? Let's just watch the students solve the problem?"

"The meaning is obvious! Just let us see if we enter the class through the back door or rely on our own skills!"

"He's really that good? It can't be that he missed the question beforehand, right?"

"What are the missing questions? Didn't you hear Teacher Han just say that these questions were just selected by the students themselves?"

......

The parents were verbose, and the students began to look at each other.

Especially the top six in the Olympiad class, everyone had a blank look on their faces.

What's going on?

Wang Yufei admitted that Li Zesheng hastily came up with a more difficult question before, and now he chose such a difficult question for him to solve in public?

Teacher Han is trying to make Wang Yufei make a joke in public?

Doesn't that make sense? Doesn't that really sit on the class that this guy entered through the back door?

In the extremely confused eyes of everyone, Wang Yufei walked up to the podium, stood beside Han Wenle, and said very embarrassedly under everyone's gaze: "Hello everyone, I am Wang Yufei." ”

"Okay then, I'll hand over the podium to you, there are six questions here, all of which are difficult problems for students to complete on their own. You have forty minutes to solve these problems, how much can you solve, understand?" Han Wenle was afraid that Wang Yufei would be greedy, so he gave a special advice.

"Okay, Mr. Han, can you start then?" Wang Yufei quickly picked up the electronic pen on the lectern and asked.

"Okay, you start solving the problem, and stop solving it at half past five sharp. Han Wenle nodded and said.

It's good, this time I helped Wang Yufei fight for five more minutes......

Looking at these six questions, Han Wenle felt that no one should care about the extra five minutes, right?

In fact, no one cares, people who know mathematics don't think it's useful to have these extra five minutes for these problems, and people who don't know mathematics don't think that five minutes can help a person solve all six problems.

The next scene that surprised Han Wenle happened.

After he agreed with Wang Yufei to start solving the problem, the boy picked up the pen and began to write quickly on the electronic blackboard, and what made him even more depressed was that this guy chose a problem that Han Wenle thought was complicated by the calculation process.

The teacher in charge of the live broadcast in the rear has already turned on the live broadcast mode synchronously, and the camera that has already been adjusted has synchronized the scene on the podium to the live broadcast of nails.

A number of words with Shen Yun Chaoyi jumped out from Wang Yufei's pen, clearly displayed in front of everyone, all kinds of complicated formulas seemed to be listed one by one without thinking at all, and the part that needed to be calculated, the maximum pause time was about five seconds, and the answer was recorded very confidently......

In this way, time passed minute by minute, and when Wang Yufei successfully solved the first question, Han Wenle looked at his watch silently, and exactly five minutes had passed......

The five-minute question is the most complex of the six questions. For a while, Han Wenle was in a trance, did he leave too much time for this little guy?

Or does he not need to think about how to compress the time for himself to express himself?
