When Ye Tianhe approached the classroom with Lin Bei and the six people, there were already many people sitting inside.

Well, there are nearly two hundred, almost half of the students participating in this competition.

The vast majority of them are students, and a small number of them are leading teachers.

Although everyone can have a good rest, there are almost no people who really rest, but men and women gather together, and the exchange is in full swing, so they are not excited.

At the same time, there is also an unknown teacher on the podium, who is showing PPT, talking about some good Olympiad examples.

Of course, there are many people who listen to these example questions, but there don't seem to be many who actually do it.

Obviously, few of the people who can come here to participate are fools, and the coach may have reminded them before coming that it is good to listen to these example problems, and don't spend more time and energy to solve them.

But with the entry of Lin Bei and others in the third middle school, the scene was naturally different.

The classroom is large, in a stepped format, and although there are a lot of people seated, there is actually room for more.

Almost all latecomers will go backwards, first, sitting in the back can have a better rest, and second, sitting in the front is too conspicuous, and it is easy to be targeted by the teacher on the stage.

If you don't have a certain strength, it's best not to sit in front.

Of course, in Lincheng No. 1 and No. 2 Middle School, the participating teams of Honghuzhi and Threesome must be sitting in front.

After all, these four schools are the four best schools in Lincheng, and the participating teams are also the strongest teams.

In particular, No. 1 Middle School directly occupies a large area, after all, there are many people in No. 1 Middle School, and there are nearly 50 people participating in the competition.

And the second middle is the second, with the appearance of thirty people, and the Honghu Zhi and the threesome are only more than twenty people.

But these more than 20 people, compared to the rest of the schools, that is not much better.

So......

The four schools occupy the best four areas in front of them, with both internal and external exchanges.

It is said to be a discussion, but in fact, it is a secret competition, looking at the example questions taught by the teacher on the stage, which school person took the lead in making it, so as to show the strength of the school.

As the saying goes, where there are people, there are rivers and lakes, and where there are rivers and lakes, there are disputes, which is true.

Although the competition only started in the afternoon.

But the competition between the major schools is starting now.

All the students who can participate in the Mathematics Olympiad are the best among the students of each school.

Each other, no one must admit defeat.

At this moment, it is the warm-up of the competition.

Of course.

This warm-up is also limited to the four schools of No. 1 and No. 2 Middle School, Honghuzhi and Threesome.

After all, only these four schools have the strength to compete in advance, and the other schools are too bad, not to mention competing with the front, it would be good to be able to barely protect themselves.

So......

The best four areas in front of the classroom are only the first and second middle schools, Honghuzhi and threesome people.

The rest of the school contestants, not only sitting in the back, but also separated from the four schools by several rows, obviously did not want to get too close and be affected.

If it's not easy to understand, let's compare the scene of the martial arts conference in the martial arts movie.

The four strongest sects sit in the top four best positions, while the rest of the sects stay far away.

But right now.

However, there is a fifth sect, under the gaze of many people, it majestically crosses everyone behind it, and comes to the front, not to mention, and even sits directly in the middle of the first four sects, as if this sect is the head of the five sects.

Suddenly, one of them was counted, and all of them had a flash in their eyes and their faces changed.

In one or two, Honghuzhi and the threesome people frowned even more, and a trace of gloom flashed in them.

"What school is it that is so rampant?"

"The best position in the middle, even the first and second middle schools, Honghuzhi and threesomes no one dared to sit, but there were only six or seven people in this new school, but they sat directly on it, which obviously did not put the first and second middle schools, Honghuzhi and threesomes in their eyes!"

"What's the matter, are they going to pick four out of four?"

"Σ (゚Д゚) is amazing!!"

Everyone looked at the visitor in disbelief.

As for who the person is, it must be needless to say that everyone knows it, and there is no doubt that it is seven people in three.

As the principal of the third middle school, Ge Tianxing can be described as a domineering group, directly sitting in the middle of the four schools, and then his eyes swept in all directions, his face was full of provocation.

Well.

The strength of the people under his command is so confident.

And as the head of a school, this occupies the best position, which doesn't seem too much, right?

Li Hao, Xu Xian and Fang Zheng had never seen such a scene, and they were slightly nervous at the moment.

But Lin Bei, Zhao Qinghan and Zeng Xi were all calm and calm.

And all three of them ignored the gazes cast by the surrounding people, and only immediately looked at the example questions that were being shown on the podium.

Especially Lin Bei, it was comparable to a bloodthirsty hungry wolf that touched a little lamb and directly put all his heart into it.

This question is quite interesting.

Saw......

[S is the set of all real numbers greater than -1, try to find all the functions from S to S f satisfies for all x, y, f ( x + f ( y ) + xf ( y )) = y + f ( x ) + yf ( x ), and for -1 < x <0 and 0< x, f(x)/x are strictly incremental. 】

It's hard, but it's not hard.

It is estimated that it will only take a minute to make it.

But that's not the point.

The focus is on the multimedia projection, not only this question, but also the second, third and fourth questions......

The difficulty of each of the latter questions is the same as one, although it is not as good as the paper questions that Ge Tianxing made in the car before, but it is not much more complicated than what Lin Bei does on weekdays.

Suddenly, Lin Bei's feeling came up, and he couldn't even control the flow of blood, and the madness surged somewhere, adrenaline, dopamine, and glucocorticoids all soared.

"I can't help it, I can't help it, I have to solve it on the spot, I guess no one will say anything, right?"

Thinking of doing it, Lin Bei didn't care about the strange eyes around him, and directly touched out his beloved pen and paper.

Then, let's go to work in public.

When others look at these questions, they really just look at them, and they actually do very little.

But Lin Bei is different, he is directly dry, and the speed of "brushing and brushing" is fast, and it seems that he is holding back too hard.

In comparison, Zhao Qinghan next to him was much more reserved, but he frowned, and thought quickly in his heart.

Zeng Xi quietly took out the pen and paper, which was relatively low-key.

As for Li Hao, Xu Xian and Fang Zheng, they didn't think about it or do it, after all, the strength of the three of them was not enough.

But even so.

It's enough for them to catch the eye.

A group of seven people occupied the best position as soon as they came, and they didn't say anything about the first and second middle schools and the Honghuzhi threesome.

Some people glanced at the blackboard and began to solve the problem, and they didn't seem to pay attention to the teacher on the stage.

Suddenly, there were many people around to talk about it.

"Who are these people?"

"So brave?"

"Don't they know that the front row position is the exclusive venue of the First and Second Middle School and the Honghuzhi Threesome?"

"There are only seven of them, and they dare to sit on it?"

"Don't they know that the example questions on the blackboard are just examples, unless they want to compete with the first and second middle schools and Honghuzhi threesomes in advance, otherwise they don't need us to do it at all?"

"Now that some of them have started working directly, they are going to compete with Ye Tian in the first middle school, Luo Lin in the second middle school, Lu Yuan in Honghu Zhi, and Zhang Chao in the threesome in advance???
