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

Chapter 48 This time it’s the Ming Emperor
Yan Zhenzhi is the minister of the Ministry of Industry, in charge of the construction of the world, and he is very familiar with the craftsmanship.

Craftsmen use many tools when making things, such as curved rulers, ink fountains, planes, rulers, and so on.

Although the vernier caliper Cao Wei drew at this time has a strange shape, it is indeed a type of ruler, and its working principle is not complicated.

However, after understanding it, Yan Zhenzhi realized how important this vernier caliper is!
Conventional rulers are more convenient when measuring some general objects that do not require such accurate readings.

But when encountering some precision objects that require accurate readings and irregular shapes, the operation of the scale is very troublesome.

The vernier caliper can easily do this!
The upper and lower pairs of calipers of the vernier caliper are very convenient for measuring the inner diameter and outer diameter, and there is almost no error!
For example, if you use an ordinary ruler to measure the diameter of the piston of a steam engine and the inner diameter of the inner wall, it will undoubtedly be an extremely tedious and torturous task. However, with a vernier caliper, you can easily and intuitively measure it with only slight adjustments. Accurate data required.

The huge Kongming lanterns, gear sets and pulley sets, and steam engines proposed and created by Cao Wei before are all artifacts that benefit the country and the people, and have extremely extensive uses for the entire society.

The vernier caliper designed by Cao Wei this time can be said to be a tool specially tailored for craftsmen, which can greatly save the energy and time of craftsmen in making and measuring some objects.

Yan Zhen looked at the design drawing of the vernier caliper in his hand and marveled in his heart!

How did Cao Wei come up with these brilliant ideas and designs?

At this moment, Yan Zhen wanted to open Cao Wei's head to see how many wonderful ideas were still inside.

"Once the vernier caliper you designed comes out, all craftsmen in the world will remember your name, and it will be a great achievement!" Yan Zhenzhi murmured.

Cao Wei threw the pen in his hand on the table, "I didn't think about it that much, but I just feel that this thing is useful."

"Well, it's very useful!" Yan Zhen nodded straightly, "It's just that this vernier caliper is only useful for craftsmen, and most other people don't understand its meaning. I'm afraid you won't be able to get such a big contribution."

Cao Wei shook his head, "It's okay, I designed this thing just to save some effort, as long as I can build the steam engine as soon as possible."

In the final analysis, the status of the craftsman is low and he is not valued by others.

Cao Wei knew that this vernier caliper had great epoch-making significance for the craftsmen, but if he showed the vernier caliper to those Confucian scholars, they would just dismiss it and ridicule it, saying that this is a strange skill.

It is worth mentioning that the vernier caliper was created by Wang Mang as early as the Western Han Dynasty.

This also makes people more suspicious of Wang Mang's identity as a traverser.

The vernier caliper made by Wang Mang only has a pair of pliers at the bottom, but compared with ordinary rulers, it still adds a lot of convenience in measuring some irregular objects and in terms of accuracy.

However, such a very ancient and heaven-defying invention has not been handed down, but due to the change of dynasties and some other reasons, the new mang copper caliper did not reappear until modern archaeology.

The reason why the Wang Mang caliper was lost is not even recorded in the historical materials. In addition to the inconvenient transportation in ancient times, the most important point is that the status of the craftsmen is too low.

If the audience for the same thing is the group of people holding pens, it will definitely leave a mark in the history books!The difference depends entirely on individual experience.

Regarding this, Cao Wei felt extremely regretful and regretful. An important cultural treasure like the vernier caliper should not end up being lost.

Now that more than 1000 years have passed, Cao Wei took out the vernier caliper again. This time, it must not be lost again, right?
Yan Zhenzhi was not one to dawdle, so he immediately ordered people to start building the vernier caliper according to the design drawings.

"Since this is the case, little brother Cao can go back today and come back tomorrow. Since the vernier caliper is easier to use than the conventional ruler, we don't have to do more useless work."

Yan Zhenzhi still understands the principle of sharpening a knife without cutting firewood by mistake.

In this way, Cao Wei bid farewell to Yan Zhenzhi and left the Ministry of Industry all the way.

When he got to the door of his house, Cao Wei saw Jiang Yu again. He was still dressed in casual clothes, standing tall and straight at the door of Cao Wei's house.

No need to think about it, Zhu Yuanzhang must be in the courtyard when Jiang Wei comes.

Cao Wei's heart began to thump.

After nodding with Jiang Yu, Cao Wei pushed open the courtyard door, and Cao Ying and Zhu Yuanzhang, who were sitting in the courtyard, stopped talking and looked at him.

"Father, you are back." Cao Ying stood up.

Cao Wei smiled, but he was absent-minded. At this moment, all he was thinking about was Zhu Yuanzhang.

In the past, he didn't know Zhu Yuanzhang's identity, so it was easy to say anything, and it made sense. Those who didn't know were innocent.

But it's different now. Because of Zhu Di's kidnapping, Cao Wei knew Zhu Yuanzhang's true identity, and Zhu Yuanzhang must also know that he knew his identity.

In this way, Cao Wei lost the protective umbrella of the "unknown person" before.

What he is facing now is the decisive, iron-blooded founding emperor of the Ming Dynasty!
Zhu Yuanzhang!
This name... sounds like a bluff!
Looking at Cao Wei who was restless, Zhu Yuanzhang burst into laughter.

After knowing his identity, Cao Wei seemed to be a different person.

"Ying'er, go to study, our old man suddenly wants to go fishing, so let your father accompany us." Zhu Yuanzhang said.

Cao Ying nodded, and obediently went back to the house, but stretched out her head to look outside.

I saw Zhu Yuanzhang say something to Cao Wei, the latter gave a forced smile, took the fishing rod and took Zhu Yuanzhang out of the yard.

After a while...

By the creek on the north side of the village.

Jiang Yu stood far away, staring intently at the two people sitting and standing by the stream.

The person sitting is naturally Zhu Yuanzhang, and the person standing is Cao Wei.

This time, Cao Wei lost his status and qualifications to be equal to Zhu Yuanzhang. He could only stand aside and serve Zhu Yuanzhang while he was fishing with his pole.

"Went to the Ministry of Industry today?"

"went."

"How about it?"

Cao Wei didn't know what exactly he asked, so he could only reply, "It's okay."

Then the two of them fell into silence. Cao Wei had nothing to say and told everything that happened in the Ministry of Works today.

Zhu Yuanzhang stared at the surface of the stream after listening, "Vernier caliper?"

Cao Wei nodded, "This vernier caliper can greatly improve the efficiency of craftsmen."

He didn't say too much. Zhu Yuanzhang didn't understand craftsmanship, so it was useless to say too much. Just let him know about it.

"Then you have done another great service, how should we reward you?"

Cao Wei waved his hands again and again: "What's your Majesty saying? Contributing to His Majesty and shining a light on Daming is what the grassroots should do. How dare you ask for rewards? As long as Your Majesty is willing to let go of past suspicions, the grassroots will be grateful!"

Zhu Yuanzhang squeezed his eyelids, turned his head and asked him with a smile:

"Why...in your mind, do we think we are such a small-minded person?"
