A quarter of an hour is fleeting.

Lu Wen also finished eating the strawberry puffs in his hand, stood up and stretched.

"Have you thought about it, class is about to end, I don't want to waste time with you after class."

"Mr. Lu, if the function f(x)=sinx+φ3(φ∈[0,2π]) is an even function, what is the φ?" A student stood up, and the question he found out from the mock paper for the college entrance examination.

"3π2" Lu Wen didn't even think about it, so he just reported the answer directly.

"Mr. Lu, I've done this question." When the student heard Lu Wen, he actually reported the answer the moment he said the question.

I can't believe it.

Lu Wen didn't explain, but continued to ask. "Anyone else has questions to ask."

Another student stood up.

"May I ask Mr. Lu, knowing that the function x is ......, what is the value of f?"

Lu Wen thought for a second. "The answer is 7.42."

"That's right." The man was unwilling, but sat down.

One by one, the people in the class stood up, and then sat down one by one.

But the atmosphere is different.

The attitude of the people in the class towards Lu Wen changed from anger at the beginning to horror.

Is this guy human! That's too fast.

The main thing is that this guy didn't even check the calculations!

A ridiculous idea arose in everyone's hearts, did Mr. Lu use mental arithmetic!

Especially Shangguan Mu.

He is different from others because of his father's identity as Shangguan Rui! He is the one who has seen the "world".

Know what the top of the world looks like.

There are geniuses among those people. For them, high school math problems are naturally not a problem.

There are even more demonic geniuses who have developed brain activity to about 20%.

They can count the answers to these questions directly in their minds.

"This Teacher Lu is none other than those geniuses who have been developed to about 20%!"

Shangguan Mu's pupils continued to dilate.

He opened the comic book that Lu Wen had given him and began to look for the answer.

As he continued to read and flip through the comics, he became more and more sure of this answer.

"Wait! Yesterday's formula was ......" Shangguan Mu suddenly thought of the formula that Lu Wen asked them to memorize yesterday.

He had an association.

Finally, when the last person's questions were answered by Lu Wen, the class was silent again.

"Well, is there anyone else who has any questions?" Lu Wen asked.

No one answered.

Because everyone doesn't know how to answer.

They couldn't help but wonder if this Teacher Lu's method was really effective.

But what is the effect of reading comics?

But Mr. Lu is really powerful, maybe the tutorials he wrote are really useful!

"Teacher Lu, I apologize for my behavior just now, and I am willing to accept your teaching method, no matter what the result is." Shangguan Mu stood up abruptly and bowed deeply.

He has already determined Lu Wen's identity!

His father once told him that he must have enough respect for these top-level existences.

Shangguan Mu then glanced at Zhou Zhen.

Zhou Zhen didn't understand why Shangguan was suddenly like this, but Shangguan Mu's meaning was obvious. So he also stood up. "I'm also open to your way of teaching, no matter what the outcome is."

The other students in the class were already a little shaken, and when they saw that Shangguan Mu and Zhou Zhen, the top student, were like this, they stood up one after another. "We're open to your way of teaching, too."

Lu Wen smiled, but he didn't expect to trigger a herd effect.

(Herd effect: the herd mentality of individuals.) The sheep are essentially a very scattered group, usually blindly rushing left and right, but once the head sheep runs, the other sheep will rush up without thinking to cater to the head sheep. ）

Shangguan Mu and Zhou Zhen, the two "heads", were a great favor to him.

"Well, in that case, from today onwards, you guys will be so good-looking comics! Did you hear that? ”

"I heard you!" The students in the class replied in unison.

"One more thing, don't do today's things right, you know!"

"Got it." The students didn't understand why, but they all said yes.

Shangguan Mu was even more excited, being taught by such a genius, he couldn't have imagined it before!

Lu Wen was also satisfied.

Finally got these students done.

After the teaching matter was settled, Lu Wen began to think about Wang Wei's confession.

I've been so busy with education these days that I've almost forgotten what I'm here for.

in the office.

Wang Jianlin came to talk to Lu Wen again.

This guy likes to run to himself and make small talk to himself whenever he is free.

If it weren't for the food he often brought to himself, he wouldn't have bothered to take care of the other party.

"Teacher Wang, I heard that a student disappeared in our school some time ago, is it true?"

Lu Wen asked Wang Jianlin behind him, and he decided to probe the tone from this guy's mouth to see if he could get some answers.

"Shh......h The principal wouldn't let him mention it. When Wang Jianlin heard Lu Wen ask this, his voice suddenly became much quieter.

"What's wrong, what's the problem?" As soon as Lu Wen heard that there was a play, his voice became smaller.

"Actually, it's very weird, I don't know a lot, I just know...... In the end, this matter is related to the old school building of the school, you must not ask anyone else, if the principal knows about this matter, he will definitely kick you out of Lily of the Valley. ”

"I see, I'll just ask." Lu Wen nodded.

I wrote down Wang Jianlin's words in my heart.

After no classes in the afternoon, Lu Wen walked around the school.

In the eyes of others, Lu Wen was just visiting the campus.

But he's already investigating.

Robots the size of a grain of rice kept jumping out of the soles of his shoes, and then lay down where Lu Wen wanted them to stay.

This is also a way for Lu Wen.

It is impossible to check it blatantly, it is easy to attract the attention of others.

When the time comes, if you are targeted, it will be troublesome.

These rice-sized robots are different, just drop them where you think they are suspicious or need to be investigated.

Because the school is very large, Lu Wen has walked a lot.

Before he knew it, he had come to an abandoned high-rise building.

"This should be the old teaching building that Wang Jianlin said." Lu Wen looked at this abandoned high-rise building, and there was actually a seal on it.

Lu Wen looked at it for a while.

Left.

Just after Lu Wen left.

The door opened.

Two strangely dressed men came out of it, one dressed in white and the other dressed in black.

The two looked at Lu Wen's departing back.

White clothes said. "Don't you go in with such a good opportunity? It seems that he really is a teacher. ”

Black clothes. "Maybe, but it's good that he didn't go in, otherwise we might have killed him......"

The two talked unscrupulously, as if killing people was normal for them.

It's just that the robot that didn't even notice the rice grains under its feet was glowing faintly.

On the other side, Lu Wen was already sitting in the office at this time, drinking a glass of honey water.

He was in a particularly good mood, he wasn't sure at first, but it was certain at the moment.

If nothing else, the old building is likely to have something to do with the weapons case that Wang Wei said.

Just take a chance to go in tonight.
