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

Chapter 69 The Small Train Made Successfully

The last day of Zhu Yuanzhang's birthday came as scheduled.

[Countdown to return: 296 days, 05 hours, 41 minutes and 27 seconds]

evening,

In the manufacturing workshop in the western suburbs of Yingtian.

After a tiring day, Cao Wei invited the craftsmen to eat.

The sunset glowed the sky red, and the faces of the craftsmen were also red, which was caused by the long-term labor and the surging blood.

Today, Cao Wei improved the food and brought over a dozen roast chickens to reward the craftsmen who had been busy for several days. It was not much, but it was enough to make everyone taste oily.

The first small train of Ming Dynasty was completed...

Yan Zhen gnawed on a chicken leg and walked over.

Yan Zhenzhi has also put in a lot of effort these days and will come over to help from time to time. He came here again this afternoon just to see if the train can be completed as scheduled.

With the efforts of everyone, after the last half-day of debugging, the little train has been able to run along the sleeper track.

"Have you thought clearly? Do you really want to give me half of the credit?" Yan Zhen asked as he squatted down next to Cao Wei, who was holding a big bowl and taking a big bite.

"Didn't I tell you earlier?" Cao Wei glanced at him strangely, "You also contributed a lot this time, don't worry, I'm not the one waiting to cross the river and tear down the bridge."

Yan Zhen grinned.

Cao Wei's temperament is too unpredictable, and he felt more at ease after hearing him confirm again.

From Yan Zhenzhi's perspective, the train Cao Wei built this time can be said to be a real national treasure!It is very important that he can participate in the manufacturing of the train and leave his name!
Yan Zhenzhi even felt that his participation in the manufacture of trains was enough to make his name in the history!
He is a civil servant, and it is a lifelong pursuit to leave a name in history!
Now, the opportunity is in front of him!
Just wait until tomorrow on Zhu Yuanzhang's birthday to report that the train was successfully built.

After eating the chicken legs clean in two bites, Yan Zhenzhi asked again:
"Before, you said you took His Majesty's two glass cups. What were they used for? Why have you never seen them before?"

Cao Wei put down the bowl, took out a strange-looking object from his bosom, and handed it to Yan Zhenzhi, "Hey, it's done, this is it."

Yan Zhen held it in his hand and looked at it repeatedly for a long time, but he couldn't see why.

I saw two transparent glazed pieces wrapped around a circle of iron wire, and two long sticks protruding from the back.

"Brother Cao, what is this?"

Cao Wei finally stuffed a bowl of thin and thick food into his stomach, and burped.

"It's called glasses, also called presbyopic glasses, which can make old people see things more clearly."

"Two priceless glass cups, you got this thing?" Yan Zhenzhi immediately frowned, feeling quite helpless.

In fact, glasses have appeared as early as the Song Dynasty, and there are records.

But because the manufacturing process is not enough, the production principle is not correct enough, the so-called glasses are just two crystal chips with weird shapes, and people can't see clearly when wearing them, and they will make people dizzy after a long time, which is really tasteless things.

It wasn't until a man named Sun Yunqiu appeared in the late Ming Dynasty that he devoted himself to the study of optical theory that he gradually perfected the functionality and practicability of glasses.

As for the glasses before that...it is really not very useful, and naturally it will not be widely spread. Even Yan Zhenzhi has only heard of it, but has never seen it.

This is why Yan Zhen was so shocked when he heard that Cao Wei made two glass cups into glasses.

Cao Wei laughed and said, "Old Yan, please be safe and don't be impatient. My glasses are different from ordinary glasses. Your Majesty will definitely be satisfied."

That's what he said, but in fact Cao Wei didn't know for sure.

Glasses, whether they are reading glasses or myopia glasses, all have a prescription.

To prepare lenses of different degrees, it is necessary to have a large amount of colored glaze.

And Cao Wei only has two glazed cups, so he can only make a pair of presbyopic glasses, and it is impossible to take care of all presbyopic eyes.

In order to make this pair of reading glasses practical enough, Cao Wei also took a lot of thought.

He found more than a dozen old people in Zhengkan Village, all of whom had different degrees of presbyopia. While polishing the glass lenses, he found these old people to try them out until most people said they could see more clearly after wearing them, and Cao Wei stopped. Let’s continue polishing.

Cao Wei found more than a dozen presbyopia for experiments, Zhu Yuanzhang's presbyopia can't be so different, can it?

"You...sigh!" Yan Zhenzhi sighed helplessly.

Things have come to this point, what he said is useless, I just hope what Cao Wei said is true.

Yan Zhenzhi handed the glasses back, but Cao Wei waved his hand.

"I can't be there for His Majesty's birthday, so you can dedicate these glasses to His Majesty on my behalf."

Yan Zhen thought about it for a while, and this is the truth.

Moreover, Cao Wei asked Zhu Yuanzhang for the colored glass cup. Zhu Yuanzhang must know who made the glasses, and there is no such thing as taking credit for it.

"Okay, I'll present it for you." Yan Zhenzhi put the reading glasses into his arms and put them away properly.

Then, Yan Zhen stood up straight.

"Then I'll go back first. I have to get up early tomorrow."

Cao Wei arched his hands towards him...

After leaving the door of the workshop, Yan Zhen didn't realize until now that if you don't take the credit, you don't have to take the credit, but if Zhu Yuanzhang is unhappy with the reading glasses, won't he take the blame for Cao Wei?

Shaking his head, Yan Zhen continued walking back without looking back.

Cao Wei is willing to give him half of the credit for making the train, which is already very moral, and such a small matter... doesn't matter.

Even if Zhu Yuanzhang doesn't like the reading glasses, he can only scold at most...

The last hint of red in the sky disappeared, and the craftsmen began to return to their accommodation rooms to rest.

Cao Wei also returned to his resting place, a relatively spacious room.

After a while, someone knocked on the door.

Cao Wei opened the door, and Song Ping was standing outside, holding a few pieces of paper in his hand, which were written all over.

Ever since Cao Wei gave Song Ping the task of editing the book, Song Ping felt as if he had been given a shot of blood, as if he didn't know what fatigue was.

During the day, Song Ping was busy working with the big guys, and when it was time to rest, he had to spare some time to start compiling the book. His enthusiasm was terrifying!
Cao Wei asked him not to be in such a hurry, and waited for Zhu Yuanzhang's birthday to pass, and he had enough time to do it again.

However, Song Ping said that he couldn't help it, and after trying to persuade him several times, Cao Wei let him go.

It seems that the old Song family is really particular about compiling books, and has energy and talent far beyond ordinary people!
"Sir, this is the summary of silkworm raising techniques that I compiled today. Please read it."

Cao Wei didn't know how to raise silkworms, so he could only follow it from beginning to end, and then ask Song Ping when he didn't understand, which happened to let Song Ping check and fill in the gaps.

Song Ping also liked the feeling of reviewing the past and learning the new, and never tired of it.

Neither of them realized at the time,

This seemingly insignificant thing they are doing now will one day set off a storm for Daming...
