Chapter 148: Studying

"Is this the steam engine?"

At the Wangfu Research and Development Institute, Gong Ming and the craftsmen stared at the machinery on the drawings, showing a surprised expression.

"Yes, this is the steam engine." Liu Jun said: "In the past, what you made was nothing compared to this, so before you develop it, I will tell you the principle of this steam engine."

Liu Jun came to a boiler, and hot water was burning in the kettle above.

He pointed to the white steam emitting from the spout of the kettle and said, "This is steam."

Gong Ming and the craftsmen surrounded the pottery jar, and no one dared to speak out, listening quietly to Liu Jun's story.

"Did you notice something when boiling water? Once the water boils, the water vapor in the kettle will suddenly increase, and the lid of the kettle will be shaken by the water vapor?"

"This official knows that sometimes there will be a rumbling sound in the mouth of the pot?" Gong Ming smiled.

Many craftsmen also laughed, and they naturally remembered this kind of ordinary thing in life.

"Well, this is the principle of the steam engine. The water vapor is quite powerful." Liu Jun picked up a bun of cloth at this time.

When the water in the kettle boiled, he blocked the cloth into the spout.

The water vapor could not flow out of the spout, and the pressure inside the pot suddenly increased, and the lid of the kettle was immediately pushed up.

"Did you see clearly? The steam engine is similar to this kettle. The body of this kettle is equivalent to a cylinder, and the lid is equivalent to a cylinder plug. The spout exists to discharge water vapor and let the lid fall down."

While saying that, Liu Jun repeatedly blocked the spout.

When steam is sprayed out of the nozzle, the jump of the lid of the pot will decrease.

The spout was blocked and the lid was raised to fly.

"I understand." Gong Ming and the craftsmen nodded slightly.

After more than half a year of research and development affairs, they have learned to think, rather than simply copying.

"This is just the function of steam. If we add a connecting rod to the lid of the pot." Liu Jun picked up a chopstick and pushed it on the lid of the pot.

His hands were just dragging the chopsticks and not holding them tightly.

Then he blocked it again and loosened the spout.

As the lid of the pot rose and fell, the chopsticks in his hand continued to rise and lower.

"Then this chopstick-like connecting rod will move up and down, front and back. If a flywheel is connected to this chopstick, can it rotate like a water wheel?" Liu Jun continued.

"My beauty, wonderful beauty!" Gong Ming kept frowning and pondering, and now he suddenly realized, "In fact, it is just using this steam power to replace the power of water."

"Yes, that's the reason." Liu Jun felt that his on-site teaching was already very vivid. If they didn't move, the IQ would not be left alone.

Gong Ming nodded frequently, "So this steam engine is actually a kettle, but this kettle is iron."

"Yes, now there is a hydraulic boring machine. You are trying to find a way to build a large kettle with good sealing properties." Liu Jun walked to the drawings, "It's not difficult to have some parts on it, just follow it."

"Yes, Your Highness." Gong Ming said, "If this thing is made, you will no longer have to worry about water flow. You can achieve the effect of hydraulic machinery anywhere."

"So, once the steam engine is developed, all the workshops can be used, and then it will be much faster to build things."

Gong Ming has already tasted the benefits of hydraulic drilling machines.

Therefore, what Liu Jun said made him very eager.

"Come on, let's take a look together." Gong Ming greeted the craftsman.

For him, he would make this thing even if he didn't eat or drink or sleep.

"Okay, I won't bother you anymore."

Seeing Gong Ming and the craftsman show unprecedented interest, he was very satisfied.

For technology, you must maintain this motivation.

After leaving the R&D Institute, Liu Jun left the royal palace.

Under the escort of the guards, he went to Gao Hongyun's house.

After the Apricot Garden was built, the spinning workshop was moved there.

Now this place has been changed into an inner school.

Three months ago, some smart and clever slaves were sent here.

Li Ran sent some scholars to teach them how to add and subtract words and numbers.

Now these servants can basically understand some simple books.

After learning about this situation, he felt it was time to play.

It will take three years for these servants to learn mathematics, physics and chemistry at the contemporary high school level.

After all, these servants do not learn Chinese, do not write articles, and do not have courses such as English history, biology and geography.

Only mathematics, physics and chemistry.

The reason for his doing this is very simple, and he trained a group of Jingzhou scientists as quickly as possible.

As for history and geography, it will be fine to gradually improve it later.

After all, he has a complete set of textbooks and does not need to be explored again.

"See Your Highness!"

At the entrance of the school, fully armed soldiers saluted Liu Jun.

Unlike ordinary schools, internal schools adopt militarized management.

The students inside are only able to go out one day a week.

But even if you go out, you can't walk alone, and at least six people have to go out together.

The purpose of this is naturally to keep knowledge confidential.

At the same time, these students are also the key targets of Feihu Guard's surveillance.

If a traitor appears, it can be solved as soon as possible.

Walking into the gate, the sound of reading floated into my ears.

There are students on both sides of the bluestone road facing the gate.

After screening, there are currently 632 students in the inner school.

As for age, he did not choose the one that was too young, after all, the one that was too young was ignorant and could not understand the importance of academic research.

Therefore, the age of students is basically between thirteen and eighteen.

Students of this age can already study according to orders.

"Six hundred people are so bad." Liu Jun felt a little sad, but he had to fight for Jingzhou.

Fortunately, he has laid the foundation for stability for Jingzhou.

He was able to take some time to teach himself.

After walking around the school, Liu Jun found that the students were all very serious.

This satisfied him very much.

Although the word "slave" is a bit cruel, they are very obedient because of this willingness.

In this way, his teaching will be relatively easier.

Back at the Qinzheng Hall of the royal palace, Liu Jun picked up three textbooks on the desk.

These textbooks were copied by him in a comprehensive way from decimals to high school mathematics, and from junior high school to high school physics and chemistry.

Some duplicate content was removed from it, and the word Rong Chao was used instead.

This way the students will not look difficult.

"Hu Wei, print these three books with 632 copies, not more than one copy. If there are similar books on the market, I will cut off your head." Liu Jun said.

Rongchao had printing techniques, such as woodblock printing.

The printing craftsman carves the content on the wooden board and then rubbing it out.

"Yes, Your Highness." Hu Wei's forehead was sweating coldly.

With books, he went to Xinghua Garden.

There is a special printing workshop for the government here.

"Six hundred and thirty-two portions, one portion cannot be lost, one portion cannot be added, otherwise your head will be cut off."
