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

Chapter 50 Too many meetings!
"cough!"

Cao Wei coughed lightly, and everyone raised their heads to see Cao Wei in a green robe.

The man who was talking about Cao Wei just now turned his head, jumped up immediately, and squeezed out a bright smile.

"Oh, Mr. Cao, why did you come so early? What I said was unintentional just now. Mr. Cao doesn't remember the mistakes of villains, so don't care about them like villains."

The others also called out "Master Cao" one after another, which was considered to be a formal acquaintance.

Although Cao Wei's position as an errand has no rank, no rank and no power, it is intriguing just because of the emperor's charter.

Moreover, Yan Zhenzhi, the minister of the Ministry of Industry, treated them with great courtesy, so naturally these people would not make any disrespectful and intimidating moves.

What's more, during this period, because of the huge sky lanterns, gear sets and pulleys, and steam engines, almost all the workers in the Ministry of Industry had heard of Cao Wei's name and knew that Cao Wei had researched all these ingenious things.

For talented people, most people will choose to think highly of them. After all, they can't do what others can do.

Besides, none of them can be regarded as official employees of the Ministry of Industry, but skilled craftsmen recruited by the Ministry of Industry from the people to build things.

Otherwise, they wouldn't be placed in the most remote corner of the Ministry of Works. The place where they work is called a craftsman's office at best, or a blacksmith shop that's slightly better than the private sector at worst.

In terms of status, even the lowest-level clerks in the Ministry of Industry are one level above these people. Naturally, they are even less likely to get into trouble with Cao Wei, who is authorized by the emperor to do things.

Seeing the glib appearance of the man in front of him, Cao Wei pursed his lips. The character of this man was somewhat similar to his own, quite like a hob.

"It's okay, you didn't say anything." Cao Wei waved his hand.

The smile on the man's face was even bigger after hearing this, "Your Excellency is really broad-minded," he said and cupped his hands, "The villain's name is Song Ping. If there is anything to do in the future, Your Excellency can just order it."

"Easy to say, easy to say." Cao Wei extended his hand to avoid hitting the smiling man, and Cao Wei was also very polite.

After a brief exchange of greetings, everyone got busy with their work again, but Cao Wei didn't have to do it himself.

Cao Wei understands theoretical knowledge, but he is powerless in practical matters. He has to be a skilled craftsman. He only needs to watch everyone make mistakes when operating. If there are some theoretical issues, Cao Wei will explain them to them.

On Cao Wei's first day working in the Ministry of Industry, everything was calm...

At noon, Yan Zhenzhi also ran over.

He had to attend a court meeting in the morning and deal with some internal government affairs of the Ministry of Industry. Only now did he have time to come and take a look.

The steam engine can be said to be the most important thing for the Ministry of Industry at this time, and Yan Zhenzhi, the minister of the Ministry of Industry, is extremely concerned about it.

When Yan Zhen arrived at the craftsman's office, he saw many craftsmen busy at work, while Cao Wei was sitting aside, drawing something on paper with a pen.

Draw again?

Yan Zhen's heart skipped a beat, and he leaned over quietly.

I saw that the object painted by Cao Wei looks like a nail, but on the cylinder of the nail, there are circles of stripes extending from the top to the end.

After Cao Wei finished the painting and put down the ink pen in his hand, Yan Zhenzhi asked: "Brother Cao, what is this you drew?"

Cao Wei glanced at him and said, "This is called a screw. It has the same function as a nail, but it is more practical than nails and is more convenient for loading and unloading."

After finishing speaking, Cao Wei handed the drawing to Yan Zhenzhi, "Have someone draw up a mold and pour it out of iron first. When you pour it, you will know what the screws are for."

Now Yan Zhenzhi has convinced Cao Wei almost unconditionally, without any hesitation, he directly finds someone to do it.

Until just after Shenshi, when the red sunset glow appeared on the horizon, Cao Wei stretched and prepared to go on duty.

At this time, a small official came over and said that Yan Shangshu told him to come over.

Cao Wei followed the little official to another building of the Ministry of Industry. This place looks like a factory building, and some craftsmen are also busy inside. There are some iron molds everywhere, and the more common ones are plowshares, adzes, and hexagonal iron rings. , Tie Yi, etc. In addition to these common ones, there are also some molds for swords and guns.

When Cao Wei came to Yan Zhenzhi's side, a craftsman was pouring molten iron into a mold with only a small hole in front of him.

It is obvious that the mold is used to pour the screws.

The efficiency of the engineering department is really fast. It only took half a day to produce the screw mold.

Wait quietly for the red molten iron in the mold to cool down. After the screws are slightly set, break open the mold, take out the screws, and run them through cold water again.

"Brother Cao, I'm afraid it can't be used?" Yan Zhen asked suspiciously, frowning.

Although the shape of a screw and a nail is very similar, it is obviously not possible to use a hammer to hit a nail because of the rings of threads on the screw.

Cao Wei took the screw and used a small hacksaw to cut a hole in the small iron bump at the top of the screw, which roughly resembled a modern slotted screw.

"That's it. Find two wooden boards." Cao Wei said.

Someone brought two wooden boards, Cao Wei randomly found a small piece of thin iron board, stuck it on the screw, and drilled down towards the two wooden boards.

Then Yan Zhenzhi and the people around him saw a magical scene.

I saw the screw in Cao Wei's hand, slowly getting into between the two wooden boards as the iron plate turned, until only one screw head was left outside.

Yan Zhen felt very novel, picked up the two boards and checked them up and down.

The two planks are very tightly combined!Not even the slightest gap!He pulled and it was firm.

"Because the screw is fastened with a ring-shaped thread, it can hold the object better than a nail, and it is not easy to fall off. It is also very simple to take out. You only need to follow the method just now and turn it in the opposite direction."

As Cao Wei spoke, he turned the screw in the opposite direction, and the screw slowly retreated from the two wooden boards.

"In this way, screws are more labor-saving and stronger than nails, will not damage the object, and can be used repeatedly."

Yan Zhenzhi couldn't help but get started, and did it himself, and found that it was exactly what Cao Wei said, and it was effortless.

Ordinary nails may bend when struck with a hammer, but screws will not. You only need to twist the nut.

And after a screw combines two objects together, it is indeed stronger than a nail,

A group of craftsmen were already praising Cao Wei at this time. They could also see that screws were better and more reliable than ordinary nails.

"Well, yes, this screw is also a good thing." Yan Zhen looked at the screw in his hand and couldn't help but sigh while nodding.

Cao Wei meets too many...
