Jia Pingan looked at the crowd, "The minister is named Gewu!"

In the last two days of this month, book friends with monthly tickets, Jazz asked for tickets.

good night!

Chapter 936

"The body is leaning back, and the feet are suspended in the air, unable to exert force?"

Xu Jingzong glanced at Li Yifu maliciously, "Li Xiang, why don't we demonstrate it?"

Li Yifu felt it didn't matter, "That's fine too."

Xu Jingzong walked behind him, Li Yifu immediately turned around vigilantly, "What are you going to do?"

"Ren Hongzhong was hugged from behind, the old man will try to hug you."

"Why didn't the old man hug you?"

Xu Jingzong looked at him, "You are so thin, look at the old man"

Old Xu's heart is wide and his body is fat, but Li Yifu has lost a lot of weight.

Li Yifu sneered and said: "It's fine for others, you old man can't believe it."

If Xu Jingzong took the opportunity to lay a black hand on the old man or something that others couldn't do, Xu Jingzong would do it with peace of mind.

Xu Jingzong was unavoidably a little resentful, and Li Yifu was surprised when he saw it.

The old dog really wanted to take advantage of the opportunity to make a black hand.

The person who knows best is your enemy!

Li Zhi's heart moved slightly, he is the emperor, naturally no one dared to hug him from behind.

Let me see how Jia Ping'an looks so confident

"Did Jia Qing try?"

Of course, Jia Pingan also fought back then.Damn, I remember one time when someone hugged him from behind and kicked him with his legs hanging in the air, not to mention the head-on bone, even when Te Niang kicked the opponent's guy, it just hurt a bit.

In that case, if you want to use your feet to severely injure your opponent, you have to lean back extremely and use your back to find a point of strength from the person who is hugging you.

But at that time, Ren Hongzhong's waist was hanging in the air, and it was even more difficult to break the head-on bone underneath. How could a young man who had never practiced do this?

"Your Majesty, I have tried it at home."

Jia Pingan did not forget to make a publicity for the new school, "Mechanics tells us that when a person hits a person with a punch while standing, the reaction force will be fed back. The reaction force goes from the fist to the arm, and finally to the foot, so why is the strength insufficient and the foot is unstable? A person who hits something with a punch and then goes backwards, that's the reaction force"

"Ren Hongzhong was hugged from the armpit, and everything from the waist down was suspended in the air. He had no way to borrow strength!"

"Leverage?"

Li Zhi was puzzled.

"Correct."

Jia Pingan went up and stood still, then threw his fist.

the punch

Li Ji shook his head, "Not cruel enough."

Master Xu Yu said with a smile: "Could it be that the British Duke can be more ruthless?"

Old Xu definitely didn't mean to be sarcastic, but Li Ji felt that he had been hit by an arrow.

"This is exerting force. Your Majesty, please see that I have to move from my feet when I swing my fist. When I want to swing a fist, my feet move first. According to the newly learned law of motion, the force is fed back to the ground, and the ground immediately gives the feet a reaction force." .This reaction force extends from the calf to the upper body, and finally turns into a punch."

Jia Ping shook his fist.

I go!

Why is there no fist style?

I remember when I was watching a boxing match in my previous life, those boxers could carry the sound of wind every time they punched.

"As for Ren Hongzhong's lower body hanging in the air, there is no feedback force, so how can this kick break Chen Jin's leg bone?"

Jia Pingan said resolutely: "I dare to say that Chen Jin's leg bones must be completely broken, as if he was hit hard!"

He looked at Sister A and found that Sister A was dumbfounded.

"Why? Because Ren Hongzhong's kick can at most cause bruises on the calf, but Chen Jin will be terrified if he wants to break the head-on bone, and begs them to strike softly. But in order to succeed once, he can only hit hard!"

These are all speculations!

The doctor came.

Jia Pingan asked: "Is Chen Jin's fracture completely broken?"

The medical officer nodded, "Mr. Jia even knew about it?"

He found that the monarch and his subjects were silent, Qi Qi looked at Jia Pingan.

"Xiao Jia!"

Ren Yaxiang was overjoyed.

He was already mentally prepared to become an official, and he was ready to teach mathematics, but he didn't expect that this matter would turn around.

Master Xu Yu took a deep breath, "I thought there would be no problem with this matter, but I didn't expect Xiao Jia to do it."

Li Zhi couldn't help laughing.

Wu Mei said something in a low voice, and the emperor's face darkened instantly.

What did sister say?

Jia Ping'an was very curious.

"Try it."

As a moderate, Li Ji felt that he should test it.

"Who's coming?"

Li Zhi looked at the prime ministers, and suddenly realized that these important ministers are too old to be troubled, what if they play off?
