Chapter 326

Qin Fangming felt that a catastrophe was imminent.

He took a deep breath and immediately stepped forward, "Principal..."

The principal turned his head, "???"

"Mr. Qin, if I remember correctly, this class should be your class, right?"

Qin Fangming looked distressed, "I know, this is my class! I have a temporary stomachache, so I asked Xu Heng to help me!"

"Because he knows this question, and..."

Before he finished speaking, Xue Laiyun retorted, "Mr. Qin, none of us know about the Xu Heng Classmates Association!"

"Why can't he?"

Product!

Fine product!

Yes!

What can Xu Heng not know?

Is there something he won't?

Qin Fangming was speechless for a moment, "%￥#￥￥@#...~"

Done!

It seems to be criticized!

Qin Fangming looked helplessly at the class where Xu Heng was writing and drawing on the blackboard while talking.

Sudden--

Qin Fangming's expression froze, "It's over! It's beyond the outline! Student Xu Heng's speech is beyond the outline!"

"It's out of line again!"

"Is this retribution?"

The face of the kiss turned black, and he wanted to spit out a mouthful of old blood.

"%￥#@￥￥%#..."

He's all bad.

There is a super outline!

Xu Heng, Xu Heng!

Are you a bad person?

Can you just help me with this question?

You have to add other knowledge points.

"Hey... careless!"

Originally, his relatives thought that this question was simple and his thinking was clear, but he never expected to be dragged away by Xu Heng, and he also talked about some super-class knowledge points and theories.

The principal, Xue Laiyun and Kevin looked at Qin Fangming together.

Qin Fangming broke out in cold sweat and dared not look directly into their eyes.

headmaster,"???"

He is very strange!

Your Teacher Qin has come back from the toilet, you should go in!

What are you still standing here for?

We're standing here, and you haven't counted yet?

You are still standing with us?

The principal's face turned dark, and he glared at Qin Fangming, "Mr. Qin, how long are you going to stand?"

The relatives are like ants on a hot pot at the moment, it doesn't matter if he goes in, let alone if he doesn't go in.

He knew that this was the principal warning him!

But how did he get in?

He went in, but he wanted to continue talking about Xu Heng's knowledge points!

Hemp egg!

This point of knowledge, he is ambiguous, the concept is vague!

How did he get in to pick up the offer?

"Woooooooo..."

Please Fang Ming is suffering!

With a sad face, he looked at the principal, Xue Laiyun and Kevin.

headmaster,"???"

Xue Laiyun frowned, "Mr. Qin, what's wrong with you? Could it be that your stomach hurts again?"

Kevin, "Ms. Qin, are you okay?"

it is good?

how good

Not bad at all!

Qin Fangming's expression was extremely ugly.

"I, I'm okay..."

The voice was almost squeezed out from between the teeth.

Principal, "Since you're fine, let's go in! How long do you want Xu Heng to substitute for you?"

Qin Fangming bit the bullet, he gritted his teeth and stomped his feet, "No, you three, I really want to go in too... But, but... But, didn't you find out? What Xu Heng said now is beyond the outline !"

"I, the concepts I said to him are a little fuzzy!"

Only then did the three realize it!

It was so!

The principal couldn't help but twitch his eyes and looked into the classroom.

Xu Heng is more than capable!

"Hey……"

The principal sighed, "Why don't you organize a study session...or ask Xu Heng to arrange a few books for our teachers so that you can study more."

"Well... so it's decided!"

"After class, I'll talk to classmate Xu Heng!"

"Ms. Xue, Mr. Kevin, you go back first."

Xue Laiyun and Kevin left one after another.

Outside the classroom, only Qin Fangming and Xu Heng were left.

As Xu Heng's topic in the classroom came to an end.

"Actually, there are many more challenges like this, such as leaning against the wall, bowing against the wall, there are many."

"But it's all the same, so be it!"

Xu Heng said this.

Qin Fangming saw the right time and planned to go in.

But how could he expect it!

Xu Heng wrote on the blackboard:

The magical Rupert's tears, why can't the bullet break?

"Leave this question to our physics teacher! Wait for him to come and let him solve it for us..."

Before the words finished, Qin Fangming entered the class with a smile on his face.

After all, Xu Heng finished speaking!

How good it is to have a seamless connection by yourself!

But next second...

His expression stiffened.

Because there are questions left by Xu Heng on the blackboard.

"Not good! Hiss... It hurts... Dear students, I must have diarrhea, and I have to go to the toilet..."

Turning around and running, "Physics class representative, after class, send the things on the podium back to my desk!"

All the students in the class were collectively dumbfounded.

Xu Heng frowned, "???"

Nima!

Come and go like the wind!

Only then did Xu Heng notice the principal outside.

Xu Heng put down his chalk, stopped lecturing, and stepped down from the stage.

Just wait for get out of class to end.

After class, the principal was waiting for Xu Heng, but a phone call made him busy.

After the physics class representative sent Qin Fangming's things to the office, he was very surprised. He didn't expect Qin Fangming to be in the office already.

"Teacher, are you okay? Are you okay?"

Qin Fangming blushed in embarrassment, "No, it's okay! Go and call Xu Heng for me."

"Good good!"

Xu Heng came to the office, "Teacher?"

Qin Fangming got up immediately, "Come here, sit down."

Xu Heng curled his lips, "I don't need it! I'm in good health, but you, teacher, have a bad stomach. You'd better take a rest!"

Qin Fangming, "*%#￥@#￥......"

Xu Heng, "So, teacher, why are you looking for me?"

Qin Fangming, "Well, student Xu Heng, I want to talk to you about Rupert's Tears..."

Xu Heng suddenly understood.

Because Xu Heng's question was too casual, Qin Fangming couldn't resist it for a while, so he pretended to have a stomachache the second time.

Fine……

Xu Heng didn't hesitate, and started chatting with Qin Fangming.

As a physics teacher, he still has some understanding of Rupert's tears.

In the 17th century, Prince Rupert of Germany gifted King Charles II of England some tadpole-shaped glass teardrops.These glass objects have wonderful properties: the head of the teardrop can withstand a hammer, but if you grab the tail of the teardrop and apply a little force, the whole glass teardrop will immediately shatter into powder.
