Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 22 Zhu Yuanzhang Shocked by the Steam Engine!

If this steam engine can really be manufactured, it will be mass-produced.

Then use it in places that require labor in all aspects. I don't know how much manpower can be saved!

The Confucian education Cao Ying received in the palace before the age of eight played a role.

At this time, he keenly realized that once the steam engine was successfully manufactured, it would bring a qualitative improvement in productivity to the Ming Dynasty!
Cao Wei looked at the thoughtful Cao Ying and nodded with satisfaction.

"Okay, I think my words have deeply touched your soul. You should think about it carefully." After saying that, he turned around and left the room.

Cao Ying frowned and looked at the three drawings on the table, as if he was making a decision in his mind.

a long time,

Cao Ying muttered softly:

"Father, I'm sorry, Daming needs a steam engine..."

While speaking, he looked out the window.

Cao Wei has already gone out.

Cao Ying took out a pen and paper and started his second-year behavior - writing a letter to Zhu Yuanzhang for the second time, reporting on the steam engine.

When Cao Ying and Zhu Yuanzhang's grandfather and grandson met last time, Zhu Yuanzhang asked Cao Ying to write a letter to the palace every few days.

Zhu Yuanzhang did this just to understand the living conditions of his eldest grandson, and how Cao Wei taught his eldest grandson by words and deeds.

At that time, Cao Ying didn't think much about it and agreed.

But Cao Ying now thinks that the idea of ​​the steam engine proposed by Cao Wei is too important, and Zhu Yuanzhang should know about it.

This time the letter was much shorter, using only one piece of letter paper.

Then, Cao Ying began to draw the three internal schematic diagrams of the steam engine.

After finishing all this, Cao Ying stuffed the letter paper and the internal schematic diagram of the steam engine he had copied into the envelope.

Then he went out with the envelope, all the way north, crossed the Qinhuai River from the bridge, and entered the market at the foot of the imperial city, where there were shouts and shouts everywhere.

Cao Ying turned a deaf ear to everything on the street and looked around.

Another street passed.

at last,

He sees the target.

A Jin Yiwei wearing a Feiyu suit and carrying an embroidered spring knife on his waist was walking in a hurry.

When pedestrians on the road saw him dressed like this, they all stayed away.

There is no way, Jin Yiwei's reputation is too bad!Not only smelly, but fierce!
They are a group of extrajudicial fanatics who are not bound by any institutions and laws, and only obey the emperor.

Even those ministers of the first and second ranks in the court would tremble three points when they saw Jin Yiwei.

However, the general Jinyiwei had disguised themselves in the streets and alleys, and became some small merchants and roadside cleaning workers, which was beneficial for them to monitor others and obtain information more conveniently.

And the Jin Yiwei that Cao Ying saw was obviously in a hurry and couldn't care less about covering up his identity.

As he was walking on the road, he saw a young man following him quietly, walking quickly side by side with him.

This boy is Cao Ying.

Jin Yiwei took a look, what a boy!How brave you are!
Didn't you see the flying fish suit on us?

Didn't you see the Xiuchun knife in our hand?

I am Jin Yiwei!

You openly teased me like this, you are not a mouse licking a cat's nose—you are courting death!
Ever since he joined Jinyiwei, he has never seen such a bold person!

Just when he was about to speak out, he heard two words uttered from the young man's mouth:
"Blue bird."

Jin Yiwei's hand that had been pressed on the handle of Xiuchun's knife was released like an electric shock. His neck felt cold and his heart tightened!
Two days ago, their top boss of Jinyiwei, the commander of Jinyiwei, Jiang Yu, assigned them a very serious task.

That is, once someone uttered the signal "blue bird" to them, they had to obey that person unconditionally after responding.

The original is this:

“If he tells you to kill someone, you have to kill someone!
If he tells you to eat shit, you have to eat shit!
If he tells you to die, just wipe your neck!
If you don't follow the order, I will skin you when you come back! "

It's a bit serious to say that. Jiang Yu was just scaring them, and the purpose was to prevent these Jin Yiwei from doing anything bad when Cao Ying found them.

Because this is the method of communication discussed by Zhu Yuanzhang and Cao Ying.

Cao Ying found Jin Yiwei and shouted the secret signal, and then Jin Yiwei brought the letter to Zhu Yuanzhang.

However, these Jinyi guards couldn't tell whether Jiang Wei was trying to scare them or not. Anyway, Jiang Wei's words were quite scary!
He swallowed and then read the code.

"flying fish."

Cao Ying nodded solemnly, took out the envelope from her arms and handed it to him.

After the Jin Yiwei took it, he stuffed it into his arms very neatly, patted it hard, and nodded solemnly.

Then, the two went their separate ways.

……

Jin Yiwei didn't dare to delay for a moment, he found Jiang Yu in the fastest time, and handed over the letter.

Turning around again, the letter had already arrived in Zhu Yuanzhang's hands.

"Steam engine?"

Zhu Yuanzhang put down the letter and picked up the three drawings beside him to look at them.

But after looking at it for a long time, I couldn't see the reason.

According to Cao Ying's description in the letter, this steam engine allowed the court to save astronomical figures.

But Zhu Yuanzhang couldn't see how powerful this steam engine was.

After studying for a long time, Zhu Yuanzhang gave up. He rubbed his brows and ordered to the side:

"Tell Yan Zhen to come straight over."

There is a specialization in art, if he doesn't understand it, he will hand it over to a professional.

If Yan Zhenzhi couldn't tell it, then that guy Cao Wei was just talking nonsense!
Thinking of Cao Wei's shameless vigor, Zhu Yuanzhang felt tired for a while.

quickly,

Yan Zhen arrived.

"Your Majesty," Yan Zhen bowed his hands and saluted.

"Come and take a look at this," Zhu Yuanzhang motioned for him to come forward.

Yan Zhenzhi did as he was told, picked up the drawings and began to ponder them carefully.

At first glance, Yan Zhen didn't take it seriously.

Boil water?water vapor?

He looked at the words marked on it and thought, what is this?

However, Zhu Yuanzhang was right in front of him, so he had to be patient and look down carefully.

however,
Seeing this, it's amazing!
With the passage of time, the expression on Yan Zhenzhi's face changed from being indifferent at the beginning to being serious, and finally turned into a look of shock, his hands were shaking with excitement, and he was even more incoherent!
"Your Majesty... Your Majesty! Who wrote this?"

"Simply, it's a work of genius! Wizards! Wizards!"

Zhu Yuanzhang was extremely surprised that even Yan Zhenzhi said this!

"Is this steam engine really so powerful?"

Yan Zhenzhi blushed with excitement, nodded and stepped forward to Zhu Yuanzhang's side.

"Your Majesty, please take a look! Let me tell you the wonderful features of this steam engine."

"This is a large pot used to boil water. The water boils to produce steam that enters the turbine..."

Since Zhu Yuanzhang didn't know much about equipment, Yan Zhen told him three times before he finally understood.

"...This is a cyclical process. As long as there is water, the steam engine can work non-stop! Combined with the gear set and pulley set that His Majesty gave to Wei Chen before, this is a steady stream of labor! Your Majesty!"

"In the future, if the imperial court builds fortifications, it may only need to operate the steam engine manually, and there will be no need to mobilize troops!"

Zhu Yuanzhang looked at the drawings in front of him, his eyes widened, and layers of wrinkles formed on his forehead.

Cao Ying said that he could save astronomical figures for the court, but is it true? !
Yan Zhenzhi had explained to him the working principle of the steam engine, and he also understood the blueprint in front of him.

He kept repeating the process that Yan Zhenzhi just mentioned, and the more he looked at it, the more feasible it became!

Zhu Yuanzhang clenched his fists and tried his best to suppress the excitement in his heart.

"Yan Aiqing! If this steam engine is built by the Ministry of Industry, it may be built?!" Zhu Yuanzhang looked at Yan Zhenzhi with a serious face.

Yan Zhen frowned: "If you follow the plan completely, you can probably make it, but you need to keep trying and making mistakes, and it will take a long time."

"Your Majesty, why don't you find the person who drew the picture? If he can guide you, the time can be greatly reduced."

After all, there is a fundamental difference between a plan view and a three-dimensional view.

It is impossible to tell what a steam engine should look like by just relying on a cross-section. If the Ministry of Engineering were to try it based only on these three drawings, I don't know if it would take until the year of the monkey.

Of course, after having a theory, it will definitely be able to be created in the end.

When Zhu Yuanzhang heard this, his expression became strange.

Looking for Cao Wei?
That kid can't put his nose on his face? !
