Reborn Xueba, you don't really think that studying is difficult, do you?

no doubt.

Lin Bei's words were sonorous, landing soundly, from the beginning to the end in one go, without the slightest stagnation.

It's as if you've recited it thousands of times long ago, and you're familiar with the road, forming a kind of physical instinct.

Instinctively navigate to find high ground, instinctively answer math problems.

There is no difference between the two.

Everyone: "..."

For a moment, the class was silent for an instant, and a needle could be heard, obviously being stunned by Lin Bei.

what? ?
What the hell is going on here? ?

Obviously a student, the existence of the bottom of the class crane, but he keeps doing math problems again and again?
And you don't even need chalk, you don't seem to need to calculate, you can just dictate the answers in seconds, an astonishing batch?
Is this a loss of morality, or a distortion of human nature, or is everyone collectively insane?
After ten seconds, everyone came back to their senses.

Then someone tremblingly said, "Then teacher, Lin...is Lin Bei's answer correct?"

"It's so fast, isn't it just talking nonsense?"

"Unless the world is crazy, I wouldn't believe it if he was killed. He can do such a difficult math problem right!"

"That's right, you won't believe it even if you beat yourself to death!"

"Add me a..."

Most of the people present shook their heads wildly.

Even Zhang San Li Si, Wang Teng and Zhao Dali didn't have the slightest confidence in Lin Bei's answer.

It's not that they want to belittle Lin Bei.

It's that the family members know each other's details.

Although Lin Bei has been reading very seriously these two days.

But the so-called earnestness is flipping through the book frantically, looking at ten lines at a glance, can this really work?

The first question was done correctly.

It can be said that Lin Bei is lucky, but if the second question is done correctly, it is not a matter of luck.

Unless the sun comes out from the west, a certain foot wins the World Cup, and the monk has lice on his head, it is absolutely impossible.

but……

They thought it was impossible.

But Yang Juntian, Lu Ren, Chu Bufan and many other high school masters all changed their expressions in an instant.

Again.

Although they haven't done this question yet.

But seeing Lin Bei's extraordinary self-confidence, the bad premonition in their hearts rose again.

"No, he did it right again, right?"

"Impossible, absolutely impossible, absolutely impossible."

"We haven't started writing to solve the problem, and we haven't even found an idea. How can he be so fast?"

"If this can be done right, doesn't that mean that his mathematical strength is still far above ours?"

Yang Juntian and the others all wanted to secretly convince themselves to forcefully suppress their inner uneasiness.

only……

Mathematics teacher Yu Huatian's reaction made them feel like falling into an ice cave, as if the sky was falling.

That is……

Although Yu Huatian did not admit the correctness of Lin Bei's answer, his serious face was full of surprise.

This meaning is also self-evident.

Lin Bei's answer is of course correct.

Not only is it right, but it is also very clear, and it is generally the same as the standard answer.

Gee!

This is absolutely perfect! !

If it was Zeng Xi, the top student in class 4, who was doing the question, Yu Huatian would definitely not have such a surprised expression.

After all, with Zeng Xi's strength, it won't be very difficult to solve this problem, and there is a high probability that he can do it now.

But the problem is...

It is Lin Bei who is doing the question now!
The former student turned into a top student in seconds?
Is this... possible?

If he hadn't seen it with his own eyes, and he had written the title himself, he probably would not have believed it, just like the people below.

But now, I have to believe it.

Getting one question right may be luck, but getting two questions right is definitely not luck, but Chi Guoguo's strength.

not to mention……

Lin Bei didn't simply say the answer, but explained the whole problem-solving process clearly.

Well, the perfect kind.

If he didn't trust Lin Bei before, he thought that Lin Bei's 150 points in the test paper should be plagiarized.

So now...

He has completely believed that Lin Bei did not plagiarize.

Just because Lin Bei can quickly answer two questions on the blackboard in seconds is enough to prove that his mathematical ability is extraordinary.

Maybe it's true.

Lin Bei really studied hard in private.

It's just that he, a teacher, didn't find out, and habitually looked at people with inherent thinking.

so that...

He misunderstood Lin Bei and wrongly blamed Lin Bei.

Feeling ashamed in his heart, he wanted to apologize to Lin Bei immediately, after all, he did something wrong.

But now is not the time to talk about that.

He asked two questions in a row, and Lin Bei dictated the answers in seconds.

Although it proved Lin Bei's strength, his face was also hot, and he couldn't hold back his face.

"Lin Bei, yes, one more question."

Yu Huatian praised Lin Bei very succinctly, and didn't say anything else, just rolled up his sleeves and did it.

"Da da da da da..."

That speed is nothing short of unpleasant.

It's like Gatling's blue fire, without stopping.

Originally, as long as two of the three questions were agreed, it proved that Lin Bei had worked hard, and the 150 points were his own doing, and the test should have ended.

But now.

Yu Huatian couldn't stop.

He wanted to see how strong Lin Bei was, and see if he could get the third question right again.

only see...

【x(e^x-a)-2lnx+2ln2-2≥0。】

[Find the value range of a. 】

Ah!
This is the third question proposed by Yu Huatian. It is the kind of question that can be solved almost overnight.

At first glance, this question is very simple.

Just two lines, in terms of complexity, it is not as good as the previous two multiple-choice questions, so it should be easy to make.

but……

That's really just at first glance.

In fact.

This question is far more difficult than the previous two questions.

Don't look at the few questions, but if you don't have extremely high strength to do it, it's daydreaming.

Even the final question of yesterday's paper, in front of this one, can only be willing to be a little brother.

without any exaggeration.

In the previous two multiple-choice questions, although Yu Huatian considered Lin Bei's elements, he was not too out of line.

Either be quite satisfactory, or dig a little hole.

Although it is difficult for ordinary people, it is also somewhat difficult for ordinary academic masters like Yang Juntian, but it is the same for top academic masters like Zeng Xi.

But the third question is different.

Except that Zeng Xi tilted her head, picked up a pen and paper and started writing, as if she had some ideas.

All the top students, including Yang Juntian, Lu Ren and Chu Bufan, frowned instantly.

Some seemingly simple questions are often the most difficult.

And some seemingly difficult and complicated questions are often relatively simple, just find an entry point.

And this question is the former.

I don't know how many people in the class, the kind of monk who looks like Zhang Er, who can't figure it out, and whose eyes are staring blankly.

"Whoa, a headache!!"

"It looks simple, but I don't have any ideas. I feel that I can't do it. It's so uncomfortable!"

"It's true that I don't have any ideas. It seems that I am a dignified student, but I am not as good as a student."

"Really, it's a shame to throw it at grandma's house."

"By the way, the teacher won't make things difficult for us on purpose, will he?"

"Oh, no!"

"The teacher didn't deliberately make it difficult for us, but for Lin Bei. This question obviously made it more difficult."

"I don't believe that he can still solve this problem."

"If he can really do it, I'll wash my hair upside down, go to the toilet, drink toilet water, and come straight to the train."

"If he can do it, I'll lick all the toilets and urinals, as Du Huize said."

"I eat a whole praying mantis with a smile on my face."

"I fencing for [-] rounds on the playground."

"My black silk dances the crab dance..."
