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

"It seems that since we have a fan base, these short videos are more or less related to you."

"In the past two days, I have only started to praise you with great fanfare!"

"Blow you! Increase your fans! So people naturally like you to talk about things."

Xu Heng, "..."

That's the truth.

"I didn't expect that I would come alive online in this way."

Xu Heng thought about it for a while, "You should go to the group to remind me! Enough is enough, otherwise it will not end well."

Group leader, "Understood!"

After all, a certain sound gets angry quickly, and is quickly forgotten by others.

Xu Heng put down his phone and let out a long sigh.

The group leader started to deal with this matter in the group.

Yang Kaixuan heard Xu Heng's sigh, "Xu Heng! You're famous, isn't it good?"

Xu Heng, "Would you like to spend money with someone?"

Yang Kaixuan, "Eh...but you're famous!"

Xu Heng rolled his eyes at Yang Kaixuan.

There is a saying that people are afraid of being famous and pigs are afraid of being strong, so it is better to keep a low profile.

"sleep."

A night without dreams.

It was Yue Pingting who woke up the next day.

Yue Pingting on the other end of the phone was very gentle.

Xu Heng got up, and sure enough, he was left in the dormitory again.

"Then I'll hang up first! Honey! I'm going to buy you breakfast!"

Cold weather!

Xu Heng put on his coat and went straight to class.

What is different from usual is that less students are memorizing and reading, but all of them are looking at me.

"Xu Heng! The one mentioned on a certain voice is you, right?"

Xu Heng, "???"

"Even the seniors of Tsinghua University and Peking University have become your fans! The kind who bow their heads in your fan group!"

Bow down?

Xu Heng, "I'm afraid you used this idiom wrong!"

Many students looked at each other in blank dismay.

"So, it's true! What's your fan group number? Can you add us to the group?"

Xu Heng, "Don't we have class groups? What do you mean, you want to go in and see those seniors from Tsinghua University and Peking University?"

Everyone said, "Mmmm! Yes! Yes! That's Tsinghua Yaoban and Peking University Yuanpei! My God! It's something I can't even dream of! I really want to see it."

Xu Heng shrugged, "I'm not the group owner! I don't have the right! Joining the group requires review. Yang Kaixuan knows the difficulty of the review, so you can understand."

Everyone looked at Yang Kaixuan instantly.

Yang Kaixuan, "???"

"Wait! What does it have to do with me? Let me tell you this! If I hadn't participated in the Mathematical Olympiad competition, I wouldn't be able to join that group! The physical problems in that group are really horrible! I don't even know how to do it!"

Everyone didn't believe what he said, and they were soft-spoken.

Yang Kaixuan, "I really don't know what you think! The seniors from Tsinghua University and Peking University you imagined are not so tall! They are in the group, and they are here for Xu Heng?"

"Compared with them, you are obviously more powerful! You still know Xu Heng in real life! They can only admire them in the group!"

"..."

After all, they let go of the idea of ​​joining the group.

Yang Kaixuan looked at Xu Heng helplessly, "Xu Heng, aren't you going too far! Use me as a shield for you."

Xu Heng smiled, "Thank you! Who told you to be eloquent!"

Yang Kaixuan, "Eh..."

With more and more people in the group.

The mixed fish and dragons are also becoming more and more obvious.

Someone chatted with Xu Heng privately and wanted to add Xu Heng as a friend, but they were all blocked by Xu Heng's settings.

And in the group, Xu Heng also made speeches from time to time.

When encountering a good topic, he will also participate in it.

After all, the more people in this group, the more topics they will be exposed to.

"@许健大大, Jianghu is in an emergency! Time is running out, please find the solution to this problem!"

This is a question posed by a sophomore at Tsinghua University.

The crowd is watching!

First, a group of high school students fell silent.

can't read!

Completely incomprehensible!

Secondly, many students at Tsinghua University and Peking University were also silent.

There were hundreds of people in the group, only a very small number started to take out pens and paper to do calculations.

topic:

A very long coaxial cable consists of a conductor cylinder with a radius of R1 and a coaxial conductor cylinder with an inner radius of R2 and an outer radius of R3 sheathed outside it, as shown in the figure.

The current I flows along the conductor cylinder and flows back from the conductor cylinder, assuming that the current is evenly distributed on their cross-sections.Let the magnetic permeability of the conductor be μ0.

Find: the distribution of the magnetic induction intensity inside and outside the cable with the distance from the axis.

A physics problem.

Xu Heng, "This study is about Ampere's law. I can figure it out by myself. What is there to ask?"

That classmate, "I beg Xu Heng to help me greatly, the sooner the better! The sooner the better!"

Xu Heng, "..."

"Fine!"

"Wait!"

In 2 minutes, Xu Heng gave the answer:

B1=μ0Ir/(2πR12)

B2=μ0I/(2πr)

B3=[u0I/（2πr）]*[（r2-R22）/（R32-R22）]

The other party said, "Thank you Xu Heng!"

But within 3 minutes, a certain sound was updated.

"He gave the answer to this question in only 1 minute, 54 seconds!!!"

Xu Heng finally understood that this guy was the one on Xingyin.

"Aren't you throwing yourself into a trap?"

"Fishing! You are!"

"Other people won't come to ask for advice on real questions, but you are better off, give me a question, let me answer it, and make a joke!"

Just kicked this guy out.

Forever trouble!

Xu Heng also explained to the group leader that that guy will always be blacklisted and not allowed to join this group.

The group leader said, "Anyway, I already reminded you in the group last night, if you continue like this, you're just asking for trouble, and you deserve to be kicked out!"

Xu Heng put aside the group news.

Click on the game and play a few rounds.

Accidentally, it was lunch time.

In the cafeteria at noon, many people paid attention to Xu Heng.

Xu Heng, "???"

Aren't you all used to it?

Why are you following me again?

Some people commented, "Xu Heng must be the one who is regarded as an idol by the seniors of Tsinghua University and Peking University!"

"It's him! It's him! It's him!"

Xu Heng, "???"

"Did everyone bring their mobile phones to school?"

Many people looked at Xu Heng with admiration.

After all, many people only know that Xu Heng has excellent grades and perfect marks in all subjects.

But the others are unknown.

Unexpectedly, this time, even the classmates of Tsinghua University and Peking University were his fans on a certain sound.

Everyone's interest in Xu Heng was instantly full again!

!!!

Xu Heng was very helpless, and finally stayed until after school in the afternoon.

Only when Yue Pingting's father came to pick her up in a car, Xu Heng heaved a sigh of relief.

In the car.

Xu Heng, "Huh..."

Father Yue, "Xu Heng, what's the matter?"

Yue Pingting smiled and said, "Being famous is a lot of pressure!"

Father Yue, "Isn't he already famous?"

Yue Pingting, "Now there are rumors in the school that Xu Heng has a fan group, and the people in the group are either top students participating in math competitions, or students from Tsinghua University and Peking University!"

Father-in-law, "!!!"

"So, is this true or not?"

Xu Heng, "Uh... count... it's true!"

Dad Yue, "Hey! Xu Heng, you are so upbeat! People want to go to Tsinghua University and Peking University, but you are good! People from Tsinghua University and Peking University have come to be your fans!"

"Amazing! Xu Heng!"

"No! I'll call your parents right now, and call our family to have a gathering at night to celebrate with you!"

Xu Heng had black lines on his face, "Uncle, it's not necessary, is it?"

Father Yue insisted, "It is necessary! Absolutely necessary!"

With that said, he called.

When they got home, Zhou Xiu'e and her mother-in-law were already busy.
