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

Chapter 56 The steam engine is completed!
"Brother Cao, this..."

Yan Zhen looked at Cao Wei with a puzzled expression, hesitant to speak.

"This is because the joint of the cylinder lacks the step of beating, which is not as tight as before, so the air leaks." Cao Wei explained.

The same is true for Yan Zhenzhi's guess in his heart, and he nodded his head when he heard the answer.

"This screw is a good thing, but it won't work if it's not tightly sealed."

After saying that, he himself began to circle around the steam engine.

A group of craftsmen were waiting not far away, chatting in low voices for some unknown reason.

Yan Zhenzhi walked around and around the steam engine, which made Cao Wei dizzy.

"Brother Cao, is there a way to solve this leaky problem?"

"Yes, just use something like rubber to fill the gap where the air leaks."

"Rubber? What is that?"

"It's like resin, soft, but elastic and filling."

Having said that, both of them were taken aback at the same time.

Wouldn't resin work without rubber?

Seemingly seeing what Yan Zhenzhi was thinking, Cao Wei said thoughtfully:

"Replacing rubber with resin is not impossible."

Yan Zhen clapped his hands and shouted to the craftsmen on the side: "Go, get some resin!"

Although the craftsmen are in the rain and fog, they must obey Yan Zhenzhi's orders. They all grew up in the mountains and soil, so they naturally know how to obtain resin.

In an instant, all the craftsmen disappeared.

After about two quarters of an hour, the craftsmen came back in batches. Almost everyone was holding a bunch of leaves in their hands. On the leaves were lumps of resin that looked very unsightly.

"Sir, are these enough?" Song Ping asked Cao Wei with a playful look on his face.

"Enough, I can't run out." Looking at these resins, Cao Wei always thought of some weird things, and his face was a little wrinkled.

After saying a word, Cao Wei asked someone to turn off the boiler, then disassembled the cylinder, baked the resin for a while on a low fire, and after it had the characteristic of sticking, spread it on the joint of the cylinder, Close it up again, and then bake it with fire for a while.

After everything was ready, everyone started the second experiment.

With the muffled sound coming from the boiler again, Cao Wei couldn't help but clenched his fists.

This time... it should be okay!
Slowly, the air pressure inside the steam engine was filled, and the piston began to move. The process was very smooth, and there was no more air leakage!

The piston drives the pull rod, and the pull rod box pulls the rear gear set and pulley set, operating in an orderly manner...

"It's done! It's done!" Yan Zhenzhi said in surprise.

In front of his eyes, the gear set and the pulley set are rotating rapidly, making people dazzled.

The craftsmen also burst into cheers, their hard work these days was finally not in vain!

Cao Wei took a deep breath.

That's right, that's what makes sense!
There is no reason why a steam engine with the simplest principle cannot be built with so much manpower and material resources!

"Brother Cao, wait! I'm going to give a speech to Your Majesty!" Yan Zhen slapped his forehead, remembering the most important point, and before Cao Wei could reply, he ran out.

This is another great achievement!

Cao Wei is really his lucky star!
……

now,

Royal study.

Jiang Yu submitted the daily reports submitted by the Jinyiwei spies stationed in Zhengkan Village, and handed them over to Zhu Yuanzhang.

In fact, in a small Zhengkan Village, there are not so many noteworthy things every day, most of them are the same.

However, Zhu Yuanzhang never tires of it, happily flipping through these daily summaries every day.

As long as his eldest grandson is well, everything will be fine.

While checking, Yan Zhenzhi's voice asking for an interview came from outside the door.

"Your Majesty, I have something important to announce!"

The sound sounded like he was in a hurry.

Putting down a few pages of paper in his hand, Zhu Yuanzhang shouted: "Come in!"

When the words fell, Yan Zhenzhi's figure squeezed into the imperial study room almost at the same time.

"What is it like to be so reckless!" Zhu Yuanzhang frowned slightly, not angry.

"Your Majesty, Your Majesty, it's not that I'm reckless, but this matter is of great significance! The steam engine...is finished!" Yan Zhen arched his hands, bowed his body, and stammered the whole sentence.

Zhu Yuanzhang suddenly opened his eyes wide, and a gleam of light flashed in his eyes!
Then the steam engine that can allow Daming to reduce countless expenses?
so fast?

This is indeed a big deal!
It was also difficult for Zhu Yuanzhang to remain calm at the moment. He didn't care to read the daily summaries in his hand, so he stood up abruptly, waved his hands and said:
"Quick! Quick! Lead the way, take us to have a look!"

Yan Zhenzhi turned around with a happy face, and led Zhu Yuanzhang all the way to the Ministry of Industry!

Arriving at the entrance of the Ministry of Industry and Commerce, when all the Ministry of Works personnel saw Zhu Yuanzhang's arrival, they all knelt on the ground respectfully and shouted: "See your Majesty!"

Zhu Yuanzhang didn't care about them, so he just followed Yan Zhenzhi all the way in and came to the craftsman's office.

"See Your Majesty!"

Cao Wei and the craftsmen behind him were about to salute, but were stopped by Zhu Yuanzhang with a wave of his hand.

"No gift, no gift."

Later, Zhu Yuanzhang saw the steam engine whizzing and running.

The chirping sound came from the air outlet of the cylinder, and the gears and pulleys made a slight friction sound as they continued to rotate.

Walking forward, Zhu Yuanzhang observed carefully. This small steam engine seemed to have endless energy, driving the gears and pulleys behind it.

Zhu Yuanzhang can't say exactly how much energy is in it, but according to the fact that even Cao Ying was able to use gear sets and pulley sets to easily pull up two to three hundred catties of boulders, and watching the steam engine running is so fast, it is definitely worth ten or eight. Cao Ying!
Wouldn't it be possible to hold up a huge object?

Zhu Yuanzhang's heart was turbulent, and he turned his head to look at Cao Wei.

"This is done?"

Cao Wei nodded silently, "Reply to Your Majesty, it's done!"

"Okay! Okay! Let us see what it can do!" Zhu Yuanzhang looked impatient, as if a child had gotten a new toy.

Cao Wei really wasn't ready for this, but it wasn't difficult.

Immediately ordered the craftsmen to set up the shelves, moved out all the important things in the craftsman's house, and tied them together with knots.

Then connect the gear set and the pulley block of the steam engine, and the steam engine pulls a pile of heavy objects and slowly rises!
Those heavy objects weighed five to six hundred catties by visual inspection, and the steam engine seemed to have no pressure at all, and it was still running smoothly!

Zhu Yuanzhang looked at all this, his eyes were wide open, and his expression was unbelievable.

Although Cao Wei had informed him in advance, when he saw this scene happen with his own eyes, he still felt a huge shock!
Is this the ingeniously crafted steam engine?

It doesn't require any manpower, just boil water. Can you do what can be done by at least a dozen people? !
