Xueba, I beg you to go and escort him quickly!

Group leader, "[Smiling expression] @许健大大!"

Feng Hechuan, "@许健大大!"

Others, "@许健大大!"

Only then did Luo Jianing realize that he had been tricked by them.

"Group masters, you guys are going too far! [Cry face expression] @许恒大大, I didn't mean it, I didn't say anything bad about you."

But Wang Hanshan and the others were stunned.

There are big question marks on each head.

"?????"

"What do you mean? What do you eat and sleep? It's just playing games, and only looking for questions when you're bored?"

"Pfft! Doesn't he even want to study?"

"I don't believe it. Doesn't he have time to study? When he's not in class? In private?"

Luo Jianing, "It is said that he does not study, and someone in the group is at the same table as him, and he is also in the same dormitory."

How could this group of seniors at Peking University believe, "What if everyone falls asleep?"

"Uh... Impossible! Not possible!"

"Based on Xu Hengda's habits, it's absolutely impossible!"

"..."

After the crazy @xuheng, Xu Heng checked the group news.

However, there are too many news 999+ in the group, so Xu Heng didn't scroll up.

So he didn't know what happened.

Xu Heng, "???"

Xu Heng appeared in the group, and in an instant, he was so excited!

"Good idol!"

"Master Xu Heng is here!"

"Hello!"

"Comparison! Xu Heng is big."

Xu Heng took a quick glance, and saw that there were many more strangers, and then looked at the group members, there were more than 230 people.

"Uh...there are so many people in the group at once?"

"@集主, have you gone out to deceive people?"

The group owner, "@许健大大, you have to have confidence in your own talent! These are all here for fame!"

Xu Heng, "Why are there so many people at once?"

The group leader, "Eh... this is really not my operation! You still have to ask @王寒山, senior, can you explain it?"

Xu Heng, "???"

Wang Hanshan, "A lot of our classmates from Peking University joined in."

Xu Heng, "!!!"

Students from Peking University... join this group?

What the hell?

"Ahem!" Xu Heng was rather embarrassed.

Wang Hanshan, "Xu Heng, I didn't have time to tell you the actual situation when I chatted with you before, so let me talk about it in the group now!"

Xu Heng was stunned, what is the actual situation, what other actual situation?

Xu Heng, "Is that what you were talking about in the group before?"

Wang Hanshan, "I mentioned it before!"

Xu Heng felt bad all over, "So, I was kept in the dark?"

Wang Hanshan, "It's like this. The first question I sent you is a difficult problem that our professor gave us in class."

Xu Heng, "It shouldn't be a problem, you can do it!"

Everyone in Wang Hanshan said, "Puff! Be yourself!"

Xu Heng, "Is that all?"

Wang Hanshan, "No, no, no! And... the second question was given by our professor... So, I'm afraid I haven't found what you asked for before..."

Xu Heng's whole body became even worse in an instant.

Nima!

impossible!

I do not believe!

How can a dignified university professor come up with such a simple question!

Suddenly, Xu Heng felt that he should be kept in the dark!

This will make you happier!

"Hey……"

He sighed resentfully.

Wang Hanshan, "@许健大大, besides, many of our students from Peking University have joined the group, mainly because they want to learn from you about your learning experience!"

"But the people in the group said that you don't need to study every day at all, this..."

The group leader and others interjected, "We thought so too at the beginning!!!"

Xu Heng, "I know it, so I just have nothing to do every day. As for the method, I can't tell for a while. After all, I have a little bit of experience in high school, and I haven't been to college yet!"

Pooh!

What you said should be taken for granted, so why don't you say why you are a university student!

Wang Hanshan, "What do you mean, when you were studying at the beginning, you accidentally learned to take risks! Not to mention all the knowledge in high school, but also in college?"

Xu Heng, "Eh...about the same!"

You can't say that you have to trust me, I really have a system, as long as you sign in, you can do anything.

It's unrealistic!

So Xu Heng could only do it perfunctorily.

Wang Hanshan and others, "%￥#@￥%..."

Look at what this guy said, there is a bit of embarrassment between the lines...

You are so embarrassing!

You are a god!

The great god among the great gods!

And these are all facts with solid evidence. You admit that you are very good, but you are still so reluctant?

"Hey……!"

Everyone looked at the group news and didn't know what to say for a while.

Xu Heng went to the group leader privately, "Group leader, are you okay?"

Lord,"???"

"I'm fine! Great Xu Heng!"

"Are you worried that it will be more chaotic?"

"I have several plans, but...Xu Heng, no matter what I arrange from now on, you must be in the group! At that time, you will have to face so many people alone, can you handle it?"

Xu Heng, "???"

"What can't I handle?"

The group owner, "If you want to classify, you can divide it into mathematics, literature, physics, chemistry, biology, history, etc.!"

Xu Heng, "Don't, don't! What if we separate high school and college?"

The group owner, "To be honest, I think I will upgrade the group to 1000 people. In the future, it will not be enough."

"Besides, if, I mean, if the members of the group are people from famous schools, they are together and dissatisfied with each other, the group will be difficult to manage..."

Management is indeed a science.

Xu Heng thought for a while, "Wait a minute! Are you thinking too much? Group leader! Can I have this popularity? Stop joking!"

The group owner, "But we already have more than 200 people."

Xu Heng had a headache.

The group owner said, "Oh, by the way, there are now more than a dozen people who have joined the review group, and I don't know if they are classmates from Peking University, or..."

Xu Heng had black lines on his face.

"Forget it, don't care about it, don't care about it, you toss it!"

After exiting Q, Xu Heng lay down and continued to sleep on his own.

The group leader is very busy.

After the review group confirmed one by one, many seniors and sisters from Peking University were put in.

Among them, the mathematics department and the physics department have the largest proportion.

After joining the group, they can even meet their classmates.

You can also mingle with the high school students in the group!

After all, everyone's same topic is Xu Heng, and the second is learning.

Looking at the review group, the last one.

Group leader, let out a long sigh of relief.

This ID is old physics, very strange.

The group leader, "@老物理, hello! Are you a student of Peking University?"

The old physicist said, "No! May I ask how to review it? I came here because of the reputation! I know that Xu Heng is very powerful!"

The group leader breathed a sigh of relief, as long as he is not a student of Peking University, it will be easy!

Besides, he is not a college student, he has the ability to "test you a few questions!"

Old physics, "OK."

The group owner directly posted the question, he is very confident in himself, this is a college entrance examination question.

topic:

A block rests on a rough, horizontal tabletop.From a certain moment on, the block is subjected to a horizontal pulling force in the same direction...

In a few seconds!

That is to say, when a person finishes reading this question, the old physics will give the answer, "C."

The group leader was slightly surprised.

"A little level!"

"Look at another question!"

The second question:

As shown in the figure, the cross section of the prism is a right triangle ABC, ∠A=30, ∠B=60.A beam of light parallel to side Ac enters the prism from point P on side AB, and exits from point M on side BC after being reflected on side AC. If the incident angle of light at point P is equal to the angle of refraction at point M, find The refractive index of the prism.

After a while, this old physicist directly gave the answer "square root three."

Lord,"!!!"
