"Xing Hebo, what do you want to do?"

After the students left, Quan Jin said angrily, "you're making trouble. You're kind. The South has been stable. You have to poke here and there. What do you want to do?"

Zhu Zhanji has left. He is going to discuss with several ministers about the tax payment of luxury businessmen, but he is not allowed to go out at present, otherwise it will cause accidents.

In front of the courtyard, the wind was blowing a little cold. Fang woke up and looked at a cluster of unknown flowers and trees in the yard. He said faintly, "can't science spread?"

Quan Jin was stunned. His trembling appearance made Fang Xing worried that the old man would suddenly fall down.

"Xing Hebo, that's a heresy!"

"There is no heresy in the world. It just depends on whether it is useful, whether it is the right way or the wrong way. Science has appeared for several years. Many people have bought relevant books, including many Confucian scholars, but who dares to say it is heresy? Who?!"

Fang Xing's eyes were sharp and sharp. He said, "you admire Fang's virtue, but virtue can't govern the country. Governing the country depends on the means of enriching the people and strengthening the country, and this... Who can give the answer? Lord Quan can explore it. Fang is not talented, but he also wants to leave something for Daming. He doesn't ask for a name forever, but... Let time give the answer."

Fang woke up and walked away. Quan Jin was meditating in the wind.

A piece of withered and yellow leaves flew in circles, stayed on his skirt for a moment, and then continued to fall down

He took a step forward and stepped on the fallen leaves. Walking by, the fallen leaves have been mixed with the soil, only the corners are slightly tilted and vibrate gently in the wind.

There was a sound of pacing in the courtyard, muttering from time to time.

"Why should science be promoted? Why should a science come out of Confucianism for thousands of years?"

"... but why do you think it's wrong? Well, I'll find some books to read."

So Quan Jin went to find Jia Quan and asked him to get himself some scientific books.

Jia Quan was stunned and asked Zhu Zhanji for instructions.

After Zhu Zhanji was stunned, he said, "this is a good thing. Lord Quan's virtue is profound. He must be able to find a place to refute Xinghe Bo."

As soon as Jia Quan left, Zhu Zhanji's face was slightly cold and said to the following officials: "the business tax must be spread slowly, starting from the luxury business, which is unshakable, but at the same time, to ensure the stability of the south, you can think slowly. Just a little, if anyone divulges this matter and Xinghe castle is preparing to build a city, then the whole family can go together."

Wei Zhi said with a smile: "Your Highness, don't worry. The ministers know the weight. If there are those people, they will have to deal with him before your highness makes a move."

Everyone said that no one dared to touch the mold.

Zhu Zhanji smiled and felt like a spring breeze. He said, "you and other important officials of the country naturally know the weight. Then go back."

From thunder to spring breeze is just a moment.

Out of the big house, uncle Peng said, "Your Majesty's majesty is more and more frightening. It's really a dragon son and a dragon grandson!"

Wei Zhi said happily, "there are successors in the Ming Dynasty. We should try our best to help create a prosperous era!"

Qian Junhua shook her head and said, "Your Highness is more anxious. It's unclear what response Peiping will make. It's urgent!"

Bao Hua, the imperial censor of Youdu, is now in charge of the Investigation Institute of Jinling City. It is the time when he is full of his career. He said, "what are you afraid of? When the former Emperor was still alive, he said he wanted to collect the tax of luxury merchants, but it has not been spread out. Who dares not to pay it?"

Qu Sheng said thoughtfully, "it's hard to deal with this. Your highness simply means that we can't do it, so we're just asking us to help. I guess Xinghe Bo is going to do it!"

Several people looked at each other, and Wei Zhi said worriedly, "Xing Hebo's hand is too fierce. He's afraid to disturb the south."

Bao Hua said in high spirits, "why should Lord Wei worry about this? Those rich businessmen don't have any control! Hold it and see if they dare to move!"

Zhao Hui, the Minister of rites, looked at him disdainfully, and then said, "I have something to do. Ladies and gentlemen, let's go first."

……

After Quan Jin got several science books, he immediately delved into them from the beginning.

The first volume of mathematics is not complicated. You can read it slowly with your ability.

"It's really exquisite. It turns complexity into simplicity."

Number is also one of the six arts. Quan Jin has more or less dabbled in it. But after seeing mathematics, he feels that science simplifies those complex descriptions and directly uses big food numbers to produce simple formulas, which is clear at a glance.

You can see the second volume, Quan Jin has claws.

I don't know how long later, he put down the second volume of mathematics and picked up physics.

Then

……

"Your Highness, Lord Quan hasn't come out of the house all the time, and the lights haven't been lit."

Zhu Zhanji looked at the sky and said, "go and have a look."

When Jia Quan got to Quan Jin and saw the black inside, he shouted, "Lord Quan!"

No one answered. Jia Quan panicked, "Lord Quan?"

"Who?"

Inside came Quan Jin's voice, which was dry and scared Jia Quan.

When the door opened, Quan Jin blinked and looked outside, and then walked to the left.

"Lord Quan, where are you going?"

"I'm going to find Xinghe Bo."

…..

Fang Xing was having a meal when he sat down at his desk and chewed.

Seeing Quan Jin coming in, Fang woke up, put down his chopsticks, got up and said, "did adult Quan eat?"

Quan Jin looked at Fang Xing with complex eyes. In front of him, the man who was much smaller than him was the most independent Xun Qi of the whole Ming Dynasty.

But now he was as casual as greeting the next door neighbor.

"I want to ask, what does that vacuum mean?"

Fang woke up and noticed that the old man was holding a book in his hand. He smiled and said, "it's just to empty the air."

"Air?"

"Yes, there is air around us all the time. For example, people suffocate because the air supply is cut off."

Quan Jin thought for a moment and said, "Yin and yang are two kinds of Qi... When there is essence, there is Qi. If Qi flows smoothly, people will be healthy. It is also a saying in one vein."

Fang Xing said helplessly, "Lord Quan, there is... In the air. Let's talk about the vacuum. Vacuum is a container or space. For example, there is no air in this room. This is vacuum."

Quan Jin hesitated and said, "isn't that man dead?"

Fang Xing looked up at the roof and said with a strong smile, "vacuum... Lord Quan, you mentioned the essence just now. You must have been involved in medical technology. You should know when you pull out the jar?"

Quan Jin nodded, a little confused.

Fang Xing asked someone to bring a small wine glass, bake it on the candle, and then cover it on his arm. It was only because of his poor workmanship that he succeeded several times in a row.

"Lord Quan, this is similar to a vacuum. The combustion of a flame needs some component in the air. After burning, it expands and becomes less, which is close to a vacuum."

Quan Jin was a little confused and asked, "do you mean... The flame burned out Yin and Yang?"

"It's not Yin and Yang, but... Hey!"

Fang Xing said: "after vacuum... Pressure changes, it can be firmly adsorbed on the arm."

"I don't understand, I don't understand!"

Quan Jin murmured to himself, and walked out of his mind.

Fang Xing couldn't bear it and said, "Lord Quan, it's air. There's air around us. You'd like to understand it as Yin and Yang, but it's not so mysterious. When the air is gone, it's a vacuum."

As for the pressure, Fang Xing doesn't want to elaborate, and he doesn't think Quan Jin is interested in learning about it.

He was just shocked by some new ideas and couldn't adapt for a while.

Quan Jin stopped, nodded and said, "I'll go back and take a look."
