"Yang Guangyi is now a useless person. Wouldn't it be worthwhile for Princess Mingda to marry him again?"

Yang Fan's words were supported by Zhao Ke and Zhao Yin.

"I'm in the royal family. I can't help myself. My father has already made an order and can't take it back. Besides, I remember my father has a pill that can repair the damaged dantian and meridians. For my happiness, my father will not I just ignored it."

Sizi smiled bitterly.

"The most ruthless emperor's house."

Yang Fan sighed.

"The most ruthless emperor..."

Si Zi kept repeating this sentence.

The most ruthless emperor's family, this sentence is not unreasonable.

"Third brother, ten sister, what's the matter with you coming to me?"

Zhao Yin interrupted, trying to relieve the sad atmosphere.

"Of course, I heard that Sun Wukong, an eight-rank alchemist, is in your mansion. Out of curiosity, I want to come over and see what kind of handsome this person who has slapped the face many times is like."

Zhao Ke said.

"I have seen it now. It shows talent and strength."

Sizi interjected.

"I saw you two comparing swordsmanship before. Sixth brother, what kind of swordsmanship your move is. I feel very powerful. There are no extra moves in every move, and I point to each other's flaws."

"Dugu Nine Swords."

Yang Fan explained.

"Dugu Jiujian? Very good, very domineering name."

Sizi praised.

"Then what is the name you used to fight against my sixth brother?"

"Tai Chi sword technique."

Sizi looked blank.

"You don't understand it. It's the clearest explanation with physics, but in your world of cultivation, you don't understand science even more."

The three of them had dark faces, but they really didn't understand what physics and science were.

"Brother Sun, please enlighten me on science and physics."

Zhao Yin bowed his hands, and Sizi and Zhao Ke cast pleading gazes.

Yang Fan smiled, looked around, and finally set his eyes on a big rock.

The raised one walked over, and the three followed curiously.

"Brother Yin, weigh the weight of this stone."

Yang Fan pointed to a half-human stone in front of him.

Without saying a word, Zhao Yin used his true energy to lift the stone.

"About eight hundred catties."

"Okay. Then I don't use my cultivation base and true essence, I only use half or less of my strength to pull it up."

"impossible!"

It was Si Zi who retorted.

"If you want to lift something, you can only lift it with a force heavier than its weight. It is impossible to lift it with a force smaller than its weight! This is basic common sense."

Sizi was a little angry at this time, thinking that Yang Fan was playing with her.

"There is nothing impossible in this world, even a man can have children."

Sizi was a little frustrated.

"Brother Sun, this is not possible, what are you going to do?"

"You'll know later."

Ten minutes later, several pulleys were fixed on the shelf by Yang Fan. The rock was firmly **** by a rope. One end of the rope passed through three pulleys in succession. At the end, only a quarter of the big rock was hung. Big little stones.

"All right."

The three of them were puzzled, not to mention the use of those three round things.

"Brother Yin, this stone is only one-fourth of the weight of the big stone. According to your understanding, I let go of the small stone. It is impossible to lift the big stone on the other end."

The three nodded together.

"Then take a good look, what is the power of science."

Three pulleys means that there is a four-fold increase in power.

As soon as Yang Fan let go of the small stone, the big stone was slowly pulled up, and finally suspended.

This surprising phenomenon made the three dumbfounded.

"Brother Sun, how did you do it?"

Zhao Yin stammered.

"This is physics in science."

Sizi was a little moved, "Science is really so amazing?"

"Ten princesses think, why would things be burned?"

"Why, of course, it can burn."

"Wrong. Because combustion requires a combustion aid, and this combustion aid is oxygen."

The three were more puzzled.

"I use action to prove it."

Yang Fan snapped his fingers, and a barrier surrounded the three of them, and then the air in the barrier was quickly evacuated.

The three of them noticed the surrounding scene, but didn't care. Because, even the monks in the foundation building stage can not breathe air for a long time, not to mention the three people in the refining stage.

"Brother Yin, you release an ordinary flame to burn this piece of wood."

Zhao Yin did so, but as soon as the flame appeared, it went out immediately.

Zhao Yin was taken aback for a moment and released again, but it was like this several times in a row, which made him a little embarrassed for a while, and people who didn't know the truth thought he was average. Not even the most common fire.

Sizi and Zhao Ke can see clearly that this is not Zhao Yin's problem, so there is only one problem, which is related to the current vacuum situation.

The two looked at Yang Fan again.

"Without oxygen, ordinary fires cannot burn."

The three of them suddenly realized.

After that, Yang Fan did a lot of physics experiments. The three of them slowly began to become interested in science, especially Si Zi. It was boring to stay in the palace all year round. For this reason, Yang Fan also bought a lot of science-related materials in the system mall Books, as to whether they can understand it, it doesn't matter to him.

Time passed quickly, and it was evening in the blink of an eye, Zhao Ke and Si Zi had to go back beforehand, leaving Yang Fan still at the Shu King Mansion.

The Shu Palace is very large, at least the size of the Forbidden City, and the number of people is large. There are hundreds of servants alone, and as many as 500 guards.

There are so many people in the mansion, which can also explain the wealth of Zhao Yin, the king of Shu. To know so many people, monthly expenses and salaries are a lot of money.

Three days later, Yang Fan got the token of the Queen's Alchemist as he wished. During the period, he also refined many pills for the Fire Emperor Zao Wou-ki. Yang Fan took half as rewards openly, and Zao Wou-ki didn't say anything.

"Brother Sun is leaving now?"

Zhao Yin stayed.

A few days of getting along made the two brothers more serious.

"I still have things to do, and I will come later. At that time, I hope that your cultivation base is not the cultivation of emptiness, but the integration period."

"Oh, let me tell you one thing before I leave, I... mid-fit!"

The space was distorted for a while, and Yang Fan directly used his divine power to disappear.

"Mixed... Mid-term..."

Zhao Yin was shocked.

At this time, in the palace, Princess Mingda’s Shufangzhai, Si Zi was playing with an iron ball **** with a rope, letting go of his hands, and the iron ball swinging back and forth.

Gradually, Si Zi discovered that the trajectory of the iron ball had shifted. As time went by, the angle of shift became larger and larger.

At last she suddenly realized.

"It turns out that this is the reason why the rotation of the ground under the feet caused the pendulum to shift."

"The emperor is here!"

At this time, a **** shouted at the door.
