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

Chapter 31 Zhu Di’s true intention

Carrying the ruler, Cao Wei walked into the blacksmith's shop in a daze, with many thoughts in his mind.

The blacksmiths are still making the cylinder block of the cylinder, and the sound of clanging sledgehammers and small hammers can be heard endlessly.

As long as the water-filled boiler can be used, there is no need to deliberately pursue precision.

Cao Wei picked up the piston that had been built and measured it carefully and repeatedly with a ruler.

古时刻度的计量单位为：1里＝15引、1引= 10丈、1丈=10尺、1R=10寸、1寸＝10分、1分= 10厘、1厘=10毫、1毫=10丝、1丝＝10忽、1忽＝10微、1微=10纤。

The ruler that Yan Zhenzhi sent to Cao Wei has scales on the upper and lower sides.

The upper scale is centimeters, centimeters, and silk, and the corresponding lower scales are suddenly, micro, and fine.

It can be said to be the most precise scale at this time.

Zhu Di also entered the blacksmith's shop, sat down on a pile of weeds beside him, and watched Cao Wei seriously holding a ruler to measure whether the diameters of the flat cylinders with the piston at the end of the cylinder were the same.

There are countless diameters of a circle, Cao Wei can only use the most stupid method, slowly moving the ruler around the center of the circle to measure one by one.

He not only needs to use the centimeters, centimeters, and silk above the scale to measure, but also uses the corresponding sudden, micro, and fine to make further accurate readings.

This is a grueling and tiring job. Cao Wei squatted there for a while and sweated his brow, but he had no time to wipe it.

Zhu Di stared at Cao Wei with great interest, as if he wanted to see him from the inside out.

Time passed by minute by minute, and an hour and a half had passed in the blink of an eye.

But for Cao Wei, his head is too big!This hour and a half is too difficult!

He was already squatting stiffly, his legs were numb, his neck was sore, and his eyes were swollen.

It would be great if Yan Zhong was here, he should be allowed to do this job...

Looking at the mark on the piston in his hand, Cao Wei nodded.

Not bad, at least the work was not in vain.

The round surface of this piston is indeed round enough to the naked eye, but when measured with a ruler, it is just like the surface of the moon, with bulges and depressions...

But fortunately, they are all about the same, a few microns and a few fibers.

It still needs to be polished slowly...

Cao Wei was worried that the blacksmiths could no longer do the polishing work later.

After carefully placing the piston, Cao Wei sat down two feet away from Zhu Di and reached out to wipe the sweat from his head.

After the cylinder block is built, more troublesome and complicated methods must be used to measure it inside and out.

Thinking about it, Cao Wei's head got even bigger!
"Brother Cao finished measuring?" Zhu Di asked in a flat tone.

Cao Wei nodded, and after a while, he quietly asked, "Your Highness, can this grass-cutter stay for two more days?"

Taking the piston home and polishing it also requires repeated and careful measurements.

It was a mistake to say that I didn't tell Yan Zhong how long it would take.

After Zhu Di listened, he nodded without hesitation:
"It's a simple matter. I'll just go back and go to the Ministry of Industry."

Cao Wei cupped his hands towards him and said with a smile, "Thank you, Your Highness."

But Zhu Di waved his hand: "Brother Cao, you don't have to be so polite with me. It is my honor to get to know such talented people as Brother Cao."

These words really made Cao Wei feel a little flattered.

I didn't know what to respond for a while, so I had to bow my hands again.

Zhu Di cast his eyes on the blacksmiths who were busy, "It seems that this big guy will spend a lot of time, why don't Brother Cao and I go outside for a walk?"

Cao Wei thought for a moment, then nodded in response.

Immediately, the two left the blacksmith's shop one after the other, Cao Wei was still half a step behind Zhu Di.

Zhu Di told him not to be polite. Naturally, Cao Wei would not just be stupid and get along with the Zhu Di brothers.

He is a vassal king!Cao Wei is very aware of the difference in status between the two.

Although I still don't know why Zhu Di played tricks on him, but there is nothing wrong with following the rules.

Zhu Di also recognized Cao Wei's wit and interest.

This is a smart man, with an extraordinary temperament, and knows how to advance and retreat!

King Zhu Di's status was only one step lower than that of the emperor, and he was one of the top dignitaries. When people in the countryside met him, they were always trembling with fear and speaking awkwardly.

This was the first time Cao Wei met him, and although he was flattering, today was only their second meeting, and Cao Wei could already communicate with him calmly.

Just now in the blacksmith's shop, Zhu Di kept staring at Cao Wei, but the latter was completely unaffected and focused on the piston in his hand.

In terms of this character alone, it is already better than most people. Even some officials in the court may not be able to deal with such changes calmly.

"I heard... Not long ago, the Ministry of Industry built a huge Kongming lantern, which can carry people to the sky. Brother Cao's idea?" Zhu Di asked quietly.

"Your Highness is really sharp. You can't hide everything from Your Highness." Cao Wei said a nice scene.

"Where did this idea come from?" Zhu Di walked side by side with Cao Wei and glanced at him.

Cao Wei grinned, showing a simple and honest look, "It's not worth mentioning. My son likes this way, so I have nothing to do with him to figure it out. This method is just figured out."

"At that time, I didn't think that it could be realized. It was the adults of the Ministry of Industry who contributed, and it was not my fault."

"No matter how powerful they are, without your method, they can't make such a big Kongming lantern. Brother Cao, don't be too modest, I have no malice towards you."

Zhu Di saw Cao Wei's politeness and alienation towards him.

In the environment of China, too much politeness and too much etiquette can only prove two things.

First, I'm not familiar with you, and second, I don't want to be familiar with you.

If ordinary people met a feudal lord and were willing to put down their posture and get close to you like this, they would have forgotten about it long ago, but Cao Wei has always been cautious in his words and deeds.

He is also a man who protects himself wisely...

Zhu Di had another comment on Cao Wei in his heart.

If Zhu Di knew that Cao Wei pointed at his father's nose and spoke arrogantly a while ago, I wonder if he would change his opinion.

"It's an honor for His Highness to look up to the grassroots, but a villain is so poor that I'm afraid I can't bear His Highness's kindness."

Speaking of which,

There was already a hint of displeasure in Zhu Di's heart.

As the most powerful vassal king in the Ming Dynasty, how could he have ever spoken so humbly to a farmer?

However, Cao Wei rejected his kindness several times!
Zhu Di is not without a temper!

At this time, he was in fresh clothes and angry horse, full of vigor, and he did not have the city and patience of Emperor Yongle later.

"Cao Wei, I know you are a smart man, so we don't need to say those useless words." Zhu Di stood still with his hands behind his back, and the warm smile at the beginning finally disappeared from his face.

"Master Daoyan said that you are very talented, and so does my king's intuition. Now I am thirsty for talents. If you are willing to join me, I will ensure that you will enjoy endless glory and wealth, and you will no longer have to work hard in the fields every day. farming."

Cao Wei sighed inwardly after listening.

It's really that people are afraid of being famous and pigs are afraid of being strong. I just came up with the idea of ​​a Kongming lantern, and I didn't even get started with making the Kongming lantern, so I was approached by Yan Wang Zhu Di.

Daoyan, you stupid bald donkey, what are you talking about?

Looking at Zhu Di who had stopped in front of him, Cao Wei knew that he couldn't continue to prevaricate.
