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

Chapter 33 The previous edict

[Countdown to return: 327 days, 06 hours, 49 minutes and 14 seconds]

You in the afternoon.

Cao Wei and Yan Zhen were in the blacksmith's shop, watching the blacksmiths carry out the final work of sealing the cylinder body.

At this time, Daming did not have rubber or screws, so the blacksmiths wanted to seal the upper and lower parts of the cylinder tightly, so they could only use tenon and tenon methods.

They inserted rivets into the small holes reserved at the edge seal of the cylinder, and then hammered them hard until the rivets became flat and tightly engaged the upper and lower parts of the cylinder.

Of course, there are many disadvantages to sealing in this way.

For example, there are a lot of rivets around the cylinder, almost one by one, densely packed, from this point of view, it is very troublesome.

What's more, this sealing method is almost disposable. If you try to open the cylinder after it is sealed, it will be damaged no matter what, but the degree of damage varies.

The blacksmiths waved their hammers vigorously.

"clang!"

"clang!"

"clang!"

"clang!"

Every time it was hit, sparks would fly out from where it was struck.

The previous piston was put in beforehand after it had been completely polished. Now only the tie rod behind it can be seen sticking out.

In the groove above the piston, copper gaskets have been turned one after another.

Other places have also been carefully crafted by Cao Wei and Yan Zhenzhi.

It shouldn't be a big problem.Cao Wei felt uneasy.

He looked at Yan Zhenzhi beside him, and found that he was also extremely nervous, and his Adam's apple kept rolling.

Finally, when it was getting dark, the blacksmiths knocked out the last rivet.

"All right!"

A blacksmith put down the hammer in his hand, made a clanging sound, took a deep breath and said to the two of them.

Cao Wei quickly paid the two taels of silver, and then found a small cart to lift the steam engine onto the cart.

Cao Wei and Yan Zhen went straight one after the other, pulling the cart back home.

When the steam engine was placed at Cao Wei's home, it was completely dark.

"It's getting late, so I'll take my leave first. I'll come back tomorrow to see if the steam engine can run successfully." Yan Zhen wiped off his sweat and said to Cao Wei.

Cao Wei and his son sent him all the way out the door.

Cao Ying couldn't wait to find the candle lamp, and carefully observed the steam engine up and down.

The steam engine built at this time is still very different from the one drawn on the blueprint, and he has never seen such a strangely shaped big iron lump.

"Father, is this steam engine complete? Will it be operational tomorrow?" Cao Ying looked at Cao Wei with excitement.

"This is only the first time it has been built. It's hard to say whether it can run smoothly, but... there should be no major problems." Cao Wei didn't know what to say, and he didn't talk too much.

If it doesn’t work this time, wait for the next time. Anyway, with experience, I will definitely do better next time.

Looking at Cao Ying who was wandering around the steam engine with a candle lamp, Cao Wei was also worried about another matter while he was pleased that the steam engine was built.

At this time, more than half of September has passed, and it will be the end of the month in a few days. Why hasn't the emperor appointed his grandson Zhu Yunwen as the heir apparent?

How did you do it?

Could it be that Zhu Yuanzhang is planning to set a new crown prince on the last day of September?

He is still waiting for Zhu Yuanzhang to give Zhu Di an explanation after he becomes the crown prince!

Wouldn't this be a bad thing?

Cao Wei stepped forward and looked at Cao Ying with a complicated expression.

If Zhu Di is really offended, even if he leaves Daming, he will be worried about his son!

"Father, what's the matter?" Cao Ying sensed the complex emotions in Cao Wei's eyes, feeling emotional and worried...

"It's nothing," Cao Wei shook his head, "It's getting late, go and have a rest. When Lao Yan comes tomorrow, let's try this steam engine together."

"Okay, father, let's take a rest early." After Cao Ying finished speaking, he returned to the room.

Cao Wei looked at the sky. The moon and stars were sparse, which was a sign of sunshine. There was no need to worry about rain. He randomly found two wooden boards to cover the top of the steam engine, and then returned to the house...

the other side,
The palace, the imperial study.

Yan Zhen returned to the imperial city and came to see Zhu Yuanzhang without stopping.

After getting Zhu Yuanzhang's permission, Yan Zhen entered the imperial study room and saw the old man sitting on the chair, looking a little tired.

"I have seen His Majesty," Yan Zhenzhi bowed his hands respectfully.

"It's so late, why did Yan Aiqing come to see us?" Zhu Yuanzhang waved his hand, motioning him to excuse himself.

"I would like to congratulate Your Majesty. Not long ago, Your Majesty ordered me to build a steam engine with Cao Wei. It has now been completed!"

"Oh?" Zhu Yuanzhang cheered up instantly.

"Is it made? How is it? Can it be used?" Zhu Yuanzhang asked three times in a row.

Yan Zhenzhi cupped his hands again: "Return to Your Majesty, the steam engine was only completed this evening, and it has not been tested yet. I have made an agreement with Cao Wei to test the operation of the steam engine tomorrow."

Zhu Yuanzhang tapped his fingers on the table a few times, "Okay, tomorrow you will wait for us at court, and we will go and have a look with you to see if this steam engine... is as good as that boy Cao Wei said. sharp."

"My minister obeys the order!" Yan Zhen answered with his hands bowed.

"Okay, step back, go back and rest." Zhu Yuanzhang covered his mouth and yawned big.

People really refuse to accept old age!

Thinking about how energetic he was back then, now he yawns all the time at night.

"I have to retire. Your Majesty should take care of your dragon body and rest early."

Yan Zhenzhi exited the imperial study, and Zhu Yuanzhang looked at an edict in front of his case.

This was planned by Zhu Yuanzhang before Cao Ying had contacted him. The above content was to establish Zhu Yunwen as the crown prince.

Originally, Zhu Yuanzhang wanted to wait for the prince to be buried in August and announce the edict in September.

But now... as time goes by, Zhu Yuanzhang seems to be shaken by this idea.

sit for a while,

After Zhu Yuanzhang yawned for the second time, he put away the edict.

Subsequently,

Under the service of the chief eunuch, he left the imperial study and went to sleep in the Qianqing Palace.

How about...wait a little longer?

Zhu Yuanzhang thought so in his heart.

The next day.

[Countdown to return: 326 days, 14 hours, 16 minutes and 27 seconds]

Cao Wei and Cao Ying got up early to practice boxing. After eating, they sat in the main room and waited for Yan Zhenzhi's arrival.

"Knock knock knock!"

Suddenly there was a knock on the door, and the father and son who were chatting stopped, and Cao Ying went to open the door.

Standing outside the door was Yan Zhenzhi, holding a set of gears and pulleys in his hands.

And beside him, there was Zhu Yuanzhang who had already disguised himself, looking like an octogenarian.

"Grandpa Zhu, Uncle Yan." Cao Ying greeted the two very politely.

Cao Wei also came over at this time.

"Old Zhu, why are you here?"

After not seeing him for nearly half a month, Zhu Yuanzhang was happily looking up and down at his eldest grandson, and glanced at him impatiently.

"What? Our old man can't come?"

"That's not true, it's just that I didn't know in advance that you were coming." Looking at Zhu Shiliu and Cao Ying who were enjoying themselves happily, Cao Weiyan said insincerely.

Cao Wei has always been suspicious of Zhu Shiliu. He suspected that the old man wanted to kidnap his eldest son.
