Daming: Old Zhu, we agreed not to rush!

Chapter 229 Brick by Brick, Blessing the Common People!

Dahondo.

The end of the year is approaching, and the task of learning has also begun to tighten.

At the end of the year, Zhu Yuanzhang's school examination for his sons was a fixed subject.

This was already the case when he was King Wu.

So at this time, even Zhu Xi sat in front of his seat seriously and listened carefully to the teacher's lecture.

Of course, it is not up to Zhu Xi to decide whether he can learn it or not.

Anyway, what you learn is what you learn, and you have to have an attitude.

"The so-called heaven and earth refer to..."

On the stage, the teacher explained the lesson carefully.

In the audience, the princes had different expressions.

Zhu Xing's eyes were wide open, and he listened very hard, but he couldn't remember what went in from his left ear and out from his right ear.

Zhu Yan's face was indifferent, obviously he had learned these things by himself, and now it was just a review.

Although Zhu Di couldn't understand it very well, he was taking notes, and the teacher was speaking while he was memorizing.

As for the remaining six and seven, they followed along shaking their heads, not sure if they understood.

Soon it was recess, and as the teacher left, Zhu Xi immediately stretched himself.

"I really envy my fifth brother, who doesn't have to study like us."

Zhu Xi said with envy.

Unlike them, Zhu Huan has been doing his own research in the Agricultural College. Zhu Yuanzhang did not have any requirements from him in the Four Books and Five Classics.

"Second brother, it's not that fifth brother is not studying, it's just that what he studies is different from ours."

Zhu Xun said to Zhu Xun.

Zhu Xi immediately said: "That's better than us studying hard here. I heard that there are too many interesting things in the agricultural college now."

Zhu Xi is the standard, as long as what he is doing now is the most painful idea, anyway, he is unwilling to do a good job in the matter at hand.

Zhu Yan didn't say any more, he knew his second brother's character, so it would be useless to say more.

"Fourth brother, you've been serious about your studies recently."

Zhu Yan turned to look at Zhu Didao.

Now Zhu Di is really studying hard.

Even for these text-like things, it was painful for him to learn.

If you can't learn, then learn by death.

In terms of willpower, Zhu Di still showed an extraordinary side.

"Third brother, I have little knowledge. The previous time was wasted, and I may have to bother you a lot later."

Zhu Di looked at Zhu Bian with a serious look on his face.

"Okay, the fourth brother is so eager to learn, if the emperor knows, he will be very happy."

Zhu Yan said with a smile.

He did know a little bit about Zhu Di's thoughts, the reason why Zhu Di suddenly became so eager to learn was to ask Su Jing for advice.

Both Zhu Biao and Zhu Huan are very intelligent and studious people.

This is exactly Su Jing's criteria for selecting students.

Several of their princes had completed lifting the tripod together before, but they got a lecture from Su Jing after discussing with Zhu Yuanzhang.

Zhu Di was preparing for the next class.

You must use your own performance to win Su Jing's favor.

"Third brother has said it. I am too playful and have never studied hard. It is lucky that my father didn't scold me."

Zhu Di said modestly.

Zhu Yan was quite surprised, it was just Su Jing who made Zhu Di change so much.

"Fourth, you have changed a lot now."

At this time, Zhu Yuanzhang's voice suddenly sounded.

"My son-in-law pays respects to his father!"

……

A group of princes immediately saluted Zhu Yuanzhang, they were quite surprised because Zhu Yuanzhang hadn't come to see them in Dabentang for many days.

The reason is very simple, that is, the year-end inventory, all kinds of officials have to deal with it.

Zhu Yuanzhang has no time.

"Get up."

Zhu Yuanzhang waved his hand, then looked at Zhu Di, feeling a little better.

These ministers all have their own pets in private, and they are doing messy dirty things, which really makes Zhu Yuanzhang quite upset.

But my sons seem to be doing well.

"Fourth, why have you suddenly become so eager to learn recently?"

Zhu Yuanzhang walked to Zhu Di's seat, and his notes were spread out on the table. Although the writing wasn't pretty, at least it was neat.

Zhu Di immediately replied: "Father, my son just felt that too much time was wasted before, so now he wants to make up for it."

"Oh, you can still have such an understanding, not bad."

Zhu Yuanzhang nodded and said: "You are all princes, and the teachers I hired for you are all famous teachers. You should study hard. Thinking about your father, I didn't have the qualifications for you back then."

"So you can only make up for it by working hard now. You can realize this, which is very good!"

Although it sounds a bit boastful, Zhu Yuanzhang really did this.

Mudleg's background is just his past.

"My son, keep in mind the teachings of my father!"

Zhu Di replied seriously.

Zhu Yuanzhang turned his head to look at Zhu Xi, his expression changed slightly.

This second child smells like mud that can't support the wall.

"Second brother, how are you doing with your recent studies?"

Zhu Yuanzhang asked.

Zhu Xi immediately said: "Reporting to my father, my son has been studying hard all the time, and I dare not slack off in the slightest."

"Humph."

Zhu Yuanzhang snorted coldly and said, "Don't dare to slack off in the slightest, how about I test you now?"

As soon as he heard about the school exam, Zhu Xi's expression changed immediately, and he hurriedly said: "My father has been working hard recently, and I have heard about it a little bit. I think it is better for my father to rest more. Don't let my father get tired because of this." Annoyed by little things."

Whether you are serious about reading or not, Zhu Xi knows, and Zhu Yuanzhang also knows, so the later the better.

"You are very self-aware. You know that the school exam will annoy me."

Zhu Yuanzhang looked at Zhu Xi and said, "Then why can't you stop worrying me?"

Zhu Xi said helplessly: "Father, I don't want to, but my son is not made of this material. I am just a stone. If you want to carve me into jade, how is that possible?"

Zhu Xi is really quite self-aware about himself.

Unfortunately, Zhu Yuanzhang did not understand him.

"Second brother, even if you are a stone, you have to be turned into jade for me!"

Zhu Yuanzhang looked serious, and said to the princes: "You are all my sons, and the country of Ming Dynasty needs you to govern it. You say you are a stone. Do you want this country to be ruled by outsiders?"

The feudal dynasty, since its birth, has been the home of the world.

Zhu Yuanzhang is even more a person who has an extreme desire to control power. He simply cannot tolerate Daming's country falling into the hands of outsiders.

"My son knows."

Zhu Xi immediately turned against him, not daring to have the slightest objection.

Because he heard the seriousness in Zhu Yuanzhang's words.

This is not a joke, if you really want to talk back, you are asking for your own death.

"what about you?"

Zhu Yuanzhang looked at the other princes and said.

"My son understands!"

All the princes nodded immediately, and the atmosphere suddenly became serious.

Zhu Yuanzhang continued: "As soon as the New Year's Eve is over, I plan to enshrine you as feudal lords. At that time, you will be vassal kings. Pay attention to your image, and look a bit like vassal kings."

The current situation in Daming is quite chaotic.

He had already thought about the matter of the vassal king.

"Yes, Royal Father!" x5
The princes responded immediately, with different expressions.

"Okay, you guys continue to study hard, my son, you can't have idiots."

Zhu Yuanzhang didn't continue talking, but only mentioned the feudal feudal seal, but he didn't say what the feudal law is, which is really a bit tantalizing.

Following Zhu Yuanzhang's departure, Zhu Xi and the others had different expressions on their faces.

They probably knew something about the feudal feudal affairs.

But what I didn't expect was that it would be so fast.

"I don't know what vassal my father wants to make for me?"

Zhu Yu said to himself, with an excited look on his face, completely forgetting what Zhu Yuanzhang reprimanded just now.

As the second prince, he must be the first one to become the feudal lord, and it is understandable that he is a little impatient.

"Second brother, it's better not to discuss this matter yet. Father didn't tell us, so he must have his own ideas. We just need to be ourselves."

Zhu Xun persuaded Zhu Xun.

He really cares about his second brother, but don't get overwhelmed, he doesn't know what happened again.

Zhu Xi said indifferently: "Third brother, it doesn't matter if you talk about it, anyway, after the new year, we will all be feudal lords, feudal lords, do you understand what I mean!"

Don't look at them as princes at this meeting, they say they have a very noble status.

But in fact, they have many restrictions, and it can be said that they are not free at all.

But if it becomes a vassal king, it will be different.

A vassal king has a rank, and a prince is just a status.

"Second brother, don't think about it too much. Even if it is a feudal clan, we probably won't go to the feudal clan right away. At least five or six years later, we still have to study in Dahontang."

Zhu Di said to Zhu Xi, directly shattering his fantasy.

There is still a distance between sealing a feudal domain and becoming a feudal domain.

"No way, fourth brother, at most, after my coming-of-age ceremony, my father should let me go to the feudal clan."

Zhu Xi didn't quite believe it.

Next year when Zhu Biao becomes an adult, he will be one year younger than Zhu Biao, which means one year.

Zhu Xi felt that he could wait.

But if it was five or six years, Zhu Xi felt a little long.

"Fourth brother, why do you say that?"

Zhu Yan also asked curiously.

Zhu Di replied: "Father granted us feudal lords because he wanted us to lead the army to fight, not to entrust the land to enjoy the blessings. When did the father think that the second elder brother can lead the army, he will let the second elder brother go to the feudal vassal? Before that, I will definitely continue my studies in Daihondo.”

Although Zhu Di is not good at reading, he is very good at this aspect.

Zhu Yuanzhang's most real idea of ​​enfeoffing the vassal was that the military power of Ming Dynasty was in the hands of his own family.

It's just that Zhu Xi and the others are still too young.

"No, I have to study hard and learn to lead soldiers in combat. Five or six years is too long!"

Zhu Xing said immediately.

He didn't want to wait that long. It would be exciting to think about going to his fief.

It's just that Zhu Xi's words fell into the ears of his younger brothers, and went directly into the left ear and out of the right ear.

Zhu Xi's talk is too much!
As soon as Zhu Di finished speaking here, it reached Zhu Yuanzhang's ears there.

"This fourth child can be seen very clearly. He is indeed the son who most resembles me when I was young."

Zhu Yuanzhang smiled and said to himself.

……

Laizhou Prefecture.

It's already pretty cold here.

"Master Su, the student has done it."

Zhu Biao tested the firmness of the finished hollow bricks one by one, and then selected several with higher strength.

After that, the kilns were opened according to these types, and dozens of pieces were fired for each type.

Then use these fired hollow bricks to build simple small "houses".

It is said that it is a house, but it is more appropriate to call it a dog house.

Then put ice cubes next to the house, and then light a fire in each "house" to observe which house the ice cubes around melt the fastest.

The whole idea is Zhu Biao's own thought. Although there are some shortcomings, the general effect can still be seen.

In the end, the homework that Zhu Biao handed over to Su Jing was a square brick with many circular holes.

This is very similar to the hollow brick in Su Jing's memory.

"Yes, it seems that you have a good understanding of heat transfer."

Su Jing nodded.

Making bricks is second to none. The scientific experimental thinking shown by Zhu Biao in the experiment is what Su Jing values ​​most.

"Mr. Su, please explain, why can we find the warmest bricks in this way?"

Mu Ying asked Su Jing.

Su Jing smiled and said, "Niu Yi, please explain."

Zhu Biao nodded and said: "Brother Mu, keeping warm is actually to block the transmission of heat. When I light a fire in these small brick stoves, the heat of the fire continues to spread outward."

"The better the heat preservation effect of the bricks, the more heat is retained inside the furnace, while the poorer ones are dissipated, which leads to the accelerated melting of ice cubes."

After listening to Zhu Biao's explanation, Mu Ying nodded and said, "I see, I understand."

Then he said excitedly: "Just making it like this can make the house more warm. If it can be promoted, it will not be the people of Ming Dynasty getting rich."

Food and clothing are the ultimate pursuit of most people in the feudal dynasty.

And living warmly can also be counted as wearing warmly.

Survive the winter!

The reason why we use the word "over" is because winter is a difficult time, so we have to pass it!
Calorie acquisition and retention is the most basic way of life for human beings.

Mu Ying was keenly aware of the significance of this kind of brick.

He was very excited, looking at Su Jing with reverence in his eyes.

Su Jing smiled and said, "Then Niu Yi, you made bricks to keep warm, do you think this is enough?"

Su Jing held the brick that looked a little strange, and shook it lightly in his hand.

Zhu Biao thought for a while and said, "Master Su, the students think that the difficulty of mass production should also be taken into consideration, not just the pursuit of warmth."

Soap is also a good thing, but it is obviously not available to ordinary people.

If this kind of hollow brick is to be popularized, the difficulty of mass production must also be considered, that is, cost control.

"Yes, you are thinking more and more comprehensively."

Su Jing nodded and said: "I think in your previous experiment, there should have been an option to balance warmth retention and production difficulty."

"of course."

Zhu Biao understood, looked at Su Jing, and already understood Su Jing's intention.

The purpose of this experiment was to allow Zhu Biao to find hollow bricks that were both warm and cheap.

"Master Su Gaoyi, the students are deeply admired."

Zhu Biao bowed towards Su Jing and said: "Just this one thing can make countless people in Daming survive the cold winter!"

One brick at a time, blessing the common people!
