Lin Danhan is the funny guy invited back by Zhang Chen. This funny guy is definitely not Huang Taiji's opponent.

But this funny guy can definitely disgust Huang Taiji.

Wan Danweizheng is a greedy political speculator. His father is not a match for Huang Taiji, and he must not be either.

At best, Wan Dan Weizheng could only disgust Huang Taiji.

The most intuitive effect of these two is to procrastinate more and delay Huang Taiji, so that he can spend more time on Mongolia's strategy.

And what Zhang Chen’s most precious thing is time now.

After the new policy resolves the most important contradiction at present, the Ming Dynasty will be able to recover.

At that time, if you play slowly with Huang Taiji, you will be able to kill him.

As for Yuan Chonghuan's memorial, I still have to reply.

How to go back?

He wants to play how he wants to play.

Zhang Chen did not expect Yuan Chonghuan to really recover Liaodong within five years.

Huang Taiji, who made a fortune in the Jisi Incident, plundered Mongolia in the southern part of the Mo and was no longer the Huang Taiji who had just succeeded to the throne in the sixth year of the Tianqi period.

After several military victories, Huang Taiji established his position as the leader of power, and promoted the Han people in a large number of internal promotions, eased the ethnic conflicts in Liaodong, and gained the support of many Han elites.

In short, many forces believed Huang Taiji very much.

At this time, the political situation of the Jin Dynasty was stable.

Yuan Chonghuan built a city in Liaodong, and his strategies were correct, but today was different from the past, and five years might not be enough.

Anyway, he has also built a very conservative city construction. For example, the current Guangning Zuosuo was directly built near the Daling River.

This is a model of progression from layer to layer.

After simply replying to Yuan Chonghuan, Chongzhen continued to start the drawings of his steam engine and shuttle spinning machine.

It is really not easy to create a steam engine in the Ming Dynasty.

It may not even be able to fix it.

You have to try and practice everything before you can draw a conclusion.

It’s not his style if you don’t do it, so you can just talk.

Is Zhang Chen's drawing a Watt's steam engine?

Nonsense, of course not.

He may not be able to draw Watt's steam engine drawings in one go.

Even if he draws it, the craftsmen of the Ming Dynasty may not be able to do it with the intricate drawings he drew.

So what was he drawing?

The first generation steam engine?

No, it is the initial steam engine principle toy.

It is called a rotary ball.

The rotary ball was invented by an engineer in ancient Greece.

The structure of this thing is actually very simple.

There is a hollow ball above, and two metal tubes are protruding from both sides of the hollow ball. The metal tube is bent, with one mouth facing down and the other mouth facing up.

This is to make the steam in the hollow ball spew out to form an impulse force, and the direction of the impulse force between the two sides is opposite, which drives the hollow ball to rotate.

The hollow ball is connected to two metal tubes, and the metal tube is connected to the sealed container below, and the container is filled with water.

After the water is heated, steam flows into the hollow ball from the two metal tubes, and spits out from the two protruding metal tube mouths of the hollow ball, forming a reverse inward, driving the metal ball to rotate.

This thing has no practical use in ancient Greece, it is just a toy.

But it can vividly illustrate the basic principles of the steam engine.

After the drawing was finished, Chongzhen called Wang Zheng from the Ministry of Works.

Why is Wang Zhenglai?

If you look at what Wang Zheng did in history, you will know why he was called over.

Before Wang Zheng became an official, he developed hydraulic, wind and load-load machinery and wrote "New Artifacts of All Tools".

Later, he compiled the "Architectural Artifacts" with Swiss missionary Deng Yuhan.

And it was published in the seventh year of Apocalypse.

What book is this?

It mainly describes the knowledge of statics in ancient Western and Renaissance, including geocentric theory, center of gravity and its solution, finding water volume, floating body volume, specific gravity, simple machinery and its combined use.

In other words, Wang Zheng has a certain knowledge of physics.

It will definitely be much easier to communicate with him.

Sure enough, after the emperor showed the drawings to Wang Zheng, Wang Zheng quickly understood what the emperor wanted to do.

Wang Zheng said: "I dared to say it out loud, I don't know why Your Majesty made this thing?"

"I've been bored recently and want to make some novel things to relieve boredom."

Wang Zheng's heart moved. The late emperor liked wood, and today he liked to make such metal objects. They were really a family!

"How, can I make it?"

“It’s OK.”

"Then give it to me tomorrow?"

This thing is not difficult. For the Ministry of Industry, it is even easier to do such a thing.

Wang Zheng hesitated for a moment and said, "Yes, I will give it to Your Majesty tomorrow."

"Okay, thank you for your hard work."

As for the shuttle spinning machine, it was actually very simple. Chongzhen called Xu Guangqi and gave him the drawings directly, asking him to try making them.

On the afternoon of the next day, Wang Zheng did make it.

The Ministry of Works has modified it with some previous materials, no wonder it is so fast.

Chongzhen asked someone to bring it into the palace and was in the Ganqing palace.

It happened that Bi Ziyan came to report on the situation of the house confiscation of Nanzhili. Seeing the emperor playing with this thing, he couldn't help but be surprised.

broken!

Are you interested in this kind of thing now?

Do you want to play with wood like the late emperor?

"Your Majesty, this is a summary memorial for the house search of Yingtian Mansion."

Wang Chengen took it, but Chongzhen stared at the thing Wang Zheng sent out in a daze, as fascinated as if he was admiring a beauty, and said intently: "Put it on the table first."

Wang Chengen placed it on the table, and Bi Ziyan stood there and did not dare to move.

Chongzhen looked at Wang Zheng and said, "Heat?"

"Here is indeed heated here."

"Then make a fire."

"Your Majesty, will it be possible to make a fire here..."

"No, let's light the fire."

If we could lit the Ganqing Palace, then what candles would be lit tonight?

Soon the fire was raised below. At first there was no movement. After the water was heated, the steam would hurt and enter the hollow ball and spray out from the mouths on both sides.

There is more and more steam, and at the mouths on both sides, it sprays downward to produce an upward momentum and on the other side, it sprays upward to produce a downward momentum.

As the steam increased, the hollow ball turned.

Bi Ziyan, who was on the side, looked speechless.

What is this?

What's this thing?

Your Majesty, have you been too idle lately?

Your Majesty, our financial situation is still a little nervous.

Your Majesty, Liaodong has a lot of military expenditure, and Yuan Keli is also asking for military expenditure.

Your Majesty, the old minister wants to sue Sun Chengzong to you. That old boy doesn’t blink his eyes when he uses money. He doesn’t use His Majesty’s money as money!

Your Majesty, stop playing. Your Majesty, you are the emperor. You should put the country first. Your Majesty!

Mr. Bi stood aside, his face turned red. He wanted to speak, but he still endured it.

Chongzhen was like an excited child. He looked at the rotating ball and asked Wang Zheng: "Love, what have you learned from this thing?"

Wang Zheng was really stunned.

What?
Chapter completed!
