No doubt.

At this moment, most of the people present saw Lin Bei frowning, and they all thought that Lin Bei was stumped by the question on the blackboard.

But there are only six people who are excluded, that is, the six participants in the third middle school, namely Zhao Qinghan, Zeng Xi, Li Hao, Xu Xian and Fang Zheng, and the team leader, that is, Ye Tianhe, the principal of the third middle school.

Zhao Qinghan also sat next to Lin Bei, and glanced at Li Daxian when he came up with it.

And then, there was no then.

After all, she knew the difficulty of these questions at a glance, and it was not bad, so she could only say that it was average!

This kind of question, she may do it on weekdays, but she was tossed by Lin Bei too late and tired last night, and she was tossed again in the car before, and how to recover until now.

So she was in a state of interest, skipped it at a glance, and fell asleep directly with her arms on her pillow.

Well, she's really going to rest.

It is impossible for her to worry about Lin Bei, after all, this kind of question is not difficult for Lin Bei at all.

And Zeng Xi, Li Hao, Xu Xian and Fang Zheng, although they can feel that it is difficult to ask questions on the blackboard, no one is worried about Lin Bei, after all, Lin Bei's strength is here.

It is not an exaggeration to say that at this moment, Lin Bei has already become the god of examination in the hearts of several of them.

In this world, there should be no high school questions that can stump Lin Bei, including Olympiad math questions.

So, they don't worry in the slightest.

As for Ye Tianhe, as the head of a school, although he is not a math teacher, he doesn't know what Lin Bei's strength is, but he can get the assurance of his old friend Ge Tianxing before he comes.

Lin Bei and Zhao Qinghan, those 1,000 percent are the seedlings of the first iMO gold medal, and they don't have to worry about their strength at all.

On weekdays, Lin Bei can not only do these Olympiad questions correctly, but also be fast, even effortless.

Ye Tianhe has seen this many times in the past half a month, so he naturally will not worry about Lin Bei, but believes it incomparably.

So, he has been acting calm.

Even, calm and relaxed.

It wasn't until he saw that the eyes of the people around him were wrong, that he glanced at Lin Bei slightly, "Classmate Lin Bei, what do you think?" ”

Hearing this, Lin Bei's frowns even tighter.

Seeing this scene, the people around him were a group of hilarious people, especially Li Daxian, the person who wrote the question on the stage.

Li Daxian originally thought that Lin Bei was very powerful, after all, he had solved his four questions in a few minutes earlier.

But now, it looks like he's going to change his attitude.

Perhaps, Lin Bei was tired of doing the questions before, otherwise it would be impossible to be thoughtless in all eight questions now.

It's just that he relied on his identity as a senior Olympiad teacher, and he didn't rush to expose Lin Bei's true face.

But in the next second, his face changed again.

It's just that after Lin Bei frowned, he shook his head again, and said helplessly to Ye Tianhe: "These questions, I really can't see them, they are about the same difficulty as the previous four questions." ”

"It's okay to do it on weekdays, but it's too different from what I expected, and the person who wrote the question is really fooling."

Li Daxian: "??? ”

Hu Feifei, Lu Dachuan: "??? ”

Jiang Tianyou, Zhou Xianlin: "??? ”

Ye Tian Luolin, Lu Yuan and Zhang Chao: "??? ”

One stone stirred up a thousand waves, and two fingers popped out thousands of sounds, unconscious, as soon as Lin Bei's words came out, they immediately made hundreds of people in a huge classroom stunned.

And in the next second, the whole fryer was boiling, like ice water dripping into a hot oil pan.

"This, this, how dare he?"

"Crazy words, this is just crazy words!"

"Even if he got a perfect score in the joint examination last time, he is the first in the city, and his strength is very powerful, but he shouldn't say such fantastical things on such an occasion, right?"

"There are a total of eight Olympiad questions on the stage, although they are just questions, but who in the audience doesn't know, this is just a random one, all of which are more difficult and biased than the real Olympiad questions."

"I bet that apart from Mr. Li, who asked the question, there are only a handful of people present who can do it."

"Even if there are many teachers who lead the team, they don't want to make one in a short time without spending a lot of time and energy."

"But now Lin Bei actually said that these questions can't be read, saying that Mr. Li is fooling people, this is too crazy, right?"

"Or is a genius a madman, he was a genius in the joint entrance examination before, and now he is showing the side of a madman, and he doesn't have much strength, but he knows how to talk about it?"

Suddenly, I don't know how many people joked about Lin Bei.

Even Ye Tian Luolin and Lu Yuan Zhang Chao joined in, after all, Lin Bei was now their biggest opponent.

But Lin Bei didn't care, just continued to wave his hand helplessly, "No, no, no!" No one really thinks that this simple eight-question question on the blackboard is difficult, right? ”

"Isn't this done with hands? No, no, no, you can even do it without your hands, just by mouth. ”

"For example, the first answer is ......"

Let A=(a1,a2,a3,......,a

Yes 1, 2, 3......

, then A's innovation order is 2, if and only if there are exactly two different elements a1 and in its innovation order array

, A1 can be ......"

"For example, the answer to the second question is ......"

"Knowing by the conditions, if

With the property P, then

=2^m-1, where m is a positive integer, it has been proven that for m=1, 2,......,9, only when m=3, 2^m-1 has the property P, at this time

=7, the bottom proves ......"

"Then the answer to the third question......"

"...... answer to the fourth question"

“……”

"Finally, the answer to the eighth question ......"

“……”

In broad daylight, in full view.

Lin Bei was very fluent, and without even the slightest pause, he reported the solution process and answer of the No. 8 Olympiad Mathematics Question displayed by Li Daxian on the blackboard in one breath.

The speed is not fast, but it is not slow, basically one question a minute, adding up to a total of eight minutes!

In these eight minutes.

There is a huge multimedia classroom, and there is no noise at all, and only Lin Bei is talking about the whole process.

In fact, at the beginning, some people still chattered, saying that Lin Bei knew how to pretend to beep, and his strength was not good.

But as Lin Bei solved the problem by oral calculation, everyone's faces changed slightly, and they became a little inexplicable.

Just because ......

The questions on the blackboard are difficult, and everyone doesn't know the answers, obviously few people know the correctness of Lin Bei's solution.

But when they saw the face of Li Daxian, the author of the question on the stage, from serious, to solemn, to solemn, to wide-eyed, wide-mouthed, and stunned.

Everyone couldn't calm down, and they didn't dare to underestimate Lin Bei anymore, and even took it seriously.

After all......

Although they didn't want to admit it anymore, Li Daxian's expression told them that Lin Beikou's solution seemed to be right?

"Isn't it?"

"It's not Lin Bei, the answer is really right, right?"

"This is an Olympiad question! I felt dizzy when I watched it, and I couldn't find the kind of solution at all. ”

"But Lin Bei just looked at it, and he didn't even need a pen, so he directly made all the calculations?"

"No way, no way, it's absolutely impossible, if he does it right, then he won't be human."

"But Mr. Li Daxian's expression is ...... again"

Suddenly, there were many people in the classroom who swallowed their saliva wildly, and their eyes looking at Lin Bei were full of complexity.

However, Lin Bei didn't pay any attention to these at all, and only paused slightly for a second after finishing the answer to the eighth question, and then looked at Li Daxian on the podium, "This teacher, you are the one who wrote the question, you should know that I solved the question right just now, right?" ”

"I said that these questions are very simple, that is, they are really simple, and the teacher should also think that they are simple."

"But I know that you must have more difficult questions, such as the 38.8G Olympiad simulation questions just now, so many, so big, it must be very interesting."

"Teacher, don't hide it, just share it in public, let's discuss it together, right?"

Li Tai Sin: "%¥#@#¥%......"

He only felt that there were 10,000 grass and mud horses galloping by in his heart in an instant, and he was really speechless!

It's true, I was distorted by Lin Bei.

Nima, do you listen to what is said above people?

Saying that the eight questions he carefully selected are simple, are the eight questions really simple?

The answer is definitely not!

The conscience of heaven and earth, these eight questions were specially selected by him for the communication before the preliminary round of this Olympiad.

It is definitely his masterpiece, and he recognizes that he is stumped by everyone present, and creates opportunities for the students of his own school.

But as a result, Lin Bei is simple on the left and simple on the right, so he is really angry!

However......

He opened his mouth to refute, but he couldn't say anything when he said it, just because these eight questions were in Lin Bei's place, it seemed to be really simple, after all, the oral calculation and answer just now, the people below might not be able to hear the truth from wrong.

But he, the person who wrote the question, must have heard it clearly, and Lin Bei's thinking process and answers were all perfect.

That is to say, in just eight minutes, Lin Bei made all the eight problems he had collected in one go, and he didn't even use scratch paper and pen.

This is a giant bull beep, right?

It's much more cow-beeping than the drunken cow of the heifer sitting in the vat, it's indescribable!

From this aspect, Li Daxian has actually admired Lin Bei to the extreme.

Doubting strength?

It is no longer possible to doubt strength.

Lin Bei's strength has exceeded his imagination as an Olympiad teacher, and he is really a monster.

It's just that the other party is still looking for a more difficult question for himself.,To open the 38.8G document by yourself.,It's very speechless.。

His most difficult problems have been done, and there are even more difficult questions there, as for the 18.8G document, although the amount is very large, the quality is just average.

They are all Olympiad questions used as ordinary exercises for students, and the difficulty is far less than the eight questions on the blackboard.

But these eight ways on the blackboard can't help Lin Bei.

How could Li Daxian dare to release the 38.8G ordinary document to be embarrassing?

In the end, he could only hug his fist at Lin Bei, shook his apology and said: "Classmate Lin Bei, I'm sorry, I was wrong before, I didn't know Taishan with my eyes, and I underestimated you." ”

"You answered all the eight questions just now, and as for the other questions, there is no need to do them again."

After speaking.

I only heard a "pop".

Li Daxian directly turned off the desktop computer, pulled out the memory card, and walked off the podium without looking back.

Well, he was already tired, his heart was tired, and his body was even more tired, and he would no longer go to the podium to continue to ask questions.

Seeing this scene, Lin Bei felt a pity, and secretly complained that Li Daxian was too petty, and obviously still remembered Li Daxian's 38.8G document.

Even if the other party said that the 38.8G document is an ordinary question, he must not believe it!

And the other side.

After Li Daxian finished speaking and stepped down.

The nearly 200 people in a huge multimedia classroom were struck by lightning at the same time, and their whole bodies stiffened.

"What...... What??? ”

"Lin Bei's eight questions, did you do them all right?"

"In just eight minutes, mental arithmetic answers, no pen and paper, all in one go, this is actually done right?"

"If he and Mr. Li Daxian didn't make an appointment in advance and deliberately sang a double reed, it would be outrageous, and it would be outrageous, and it would be outrageous!"

"Can anyone tell me if this is reality or a dream, give me a slap in the face next door."

"Push harder, pump hard (ง °Θ°)ว......"
