Zhu Yan looked at Zhu Di's back and snorted softly.

"Brother, my talent is not lost to the third and fourth brothers, and I have defeated them in the main hall, why don't you let me lead the army? I also went to Jinxian to improve the technology of iron smelting for my brother. ”

"The Yuan people are more savage and cruel than the Han people, they will cut off the heads of the enemy and hang them under the horses as trophies, you are still young, even if your father asks you to go, I don't approve of it."

This is Zhu Yuanzhang's judgment on the ability of the vassal king for more than ten years, and it cannot be changed overnight.

The reason why Zhu Rong cares about it is because it is related to the distribution of military power.

The Qin Dynasty adopted a centralized system, and the Han Dynasty adopted a feudal system, and the father thought that they both had drawbacks, so he simply came up with one dynasty and two systems.

It was allocated to the army of the vassal king, and the feudal court was autonomous, and the imperial court controlled the highest decision-making power.

It was stipulated that the guards of the vassal kings could not exceed 19,000 people, except for two vassal kings, one was Zhu Di, the king of Yan, and the other was Zhu Quan, the king of Ning.

They commanded an army of more than 100,000 people, more than ten times more than the average vassal king.

And these are all things they have accumulated and obtained.

Zhu Yuanzhang will not favor a certain heir, in the matter of power, depending on the ability of each vassal king, just like his determination to fight corruption, no one can change.

"I hope Jiangxi Jinxian can come to the good news soon."

………………

"Your Royal Highness the Prince, the furnace has ruined ......"

In the Chunhe Palace, the deputy envoy who was ordered to modify the furnace looked frightened, and after half a month came to report the news.

"What's going on?" Zhu Biaoxin pinched up suddenly.

"According to the method said by King Qi, the minister built a layer in the furnace, but the molten iron solidified in the middle of the furnace, and the furnace temperature was not enough, so it couldn't come down, and it couldn't be boiled, so he had to smash the furnace."

The deputy envoy looked up at Zhu Biao and said worriedly.

A furnace that looks like it's all salt clay, as if it's not worth much, but it takes a month of hard labor to build.

It's worth a lot.

Zhu Biao's face showed a solemn expression, "Please come over, seventh brother." ”

Zhu Yu came to Chunhe Palace, and saw the frightened look at him, half a moon was gone, the whole person lost a lot of weight, and white hair grew on his temples.

"Made?"

"King Qi ......"

The envoy spoke again.

According to his description, Zhu Yan analyzed the reason, and the Shang and Zhou dynasties were able to refine bronze, indicating that the furnace temperature of coal burning could reach at least 1,000 degrees.

Can't get rid of it?

It is because a thick layer of salt sludge is added to the furnace, which causes the temperature to not go up.

Zhu Yu quickly analyzed the reason.

The striking feature of the blast furnace is that there are many layers of compartments in the furnace body, but the temperature can be burned in later generations, so there is no solidification.

How do I change it?

"It must be the cinder that is blocked inside, the wind can't get in, it can't burn, the molten iron cools and forms lumps, and it is doped with ignition ink."

Grass ash acts as a laxative and prevents condensation.

Zhu Yan thought about it carefully, and then looked at the envoy solemnly.

"His Royal Highness the Prince, the ministers don't dare to change it now, if it is not changed well, a furnace will be scrapped if it is changed, and the work will be wasted before the one-month construction period, and the court will urge the delivery of ......"

The envoy looked at Zhu Biao.

Zhu Yu's eyes were firm: "Brother, believe me again!" ”

Zhu Biao sighed lightly, and after a moment in his heart, he looked at the envoy: "Go back and tell Ambassador Zhao, according to what my seventh brother said, my father will blame you, and I will intercede for you, and I will not implicate you." ”

"I'm willing to try again......"

That pair lit up his eyes and breathed a sigh of relief.

At this time in the Fengtian Palace, Zhu Yuanzhang was looking at a painting in his hand, the servants were working up and down, and as soon as the deputy envoy entered the palace, Zhu Yuanzhang heard the report.

Hearing that Zhu Rong was refining the waste furnace, Zhu Yuanzhang stared at his eyes, whether he was angry or not depended on Zhu Rong's reaction: "What did King Qi say?" ”

"King Qi asked people to continue refining."

Zhu Yuanzhang put down the drawings in his hand, and his anger subsided a little, "Let King Qi come to Fengtian Temple." ”

Zhu Yuanzhang is the person who interprets the accounts of the autumn queen to the extreme, and the corrupt officials in the early years, even if Zhishi lived in seclusion for five years or ten years, he was also arrested and questioned.

Zhu Yu came to Fengtian Palace, and when he entered the door, he saw Zhu Yuanzhang pacing beside the imperial case, hanging his head, thinking about something.

"Father, are you looking for me?"

Zhu Yuanzhang stopped, looked at this son, and said with a straight face: "We heard that the deputy envoy of Jiangxi Jinxian Iron Smelting Institute has entered the palace?" ”

Father must have gotten the news.

"If you have wasted an iron-making furnace, will my father punish me?"

"Remember, let's teach you how to be a vassal king?"

"Remember, Ming, Ren, Diligent, and Judgmental, to punish the vassal, but also to wait for him to finish this matter, so that he will not cover up his merits because of wrong judgment, and will not reduce his punishment because the crime is too light......"

In a word, either don't do it, or do it if you want to do it.

That's what Zhu Yuanzhang taught them, Zhu Yuxin said that his father was not conniving at him, but planning to settle accounts after the autumn, Zhu Rong looked up and found that the Hongwu Emperor looked cold and didn't say a word.

"Even if my father wants to punish him, I want to make it, I heard that the Ming Dynasty and the Northern Yuan are about to fight, and they must replace their armor and weapons, and they are opening up wasteland everywhere in the world, how can they open up wasteland without farm tools, I said it, my father will punish it!"

"Get out!"

Zhu Yu turned around and walked out of the Fengtian Hall very angrily.

Zhu Yuanzhang didn't speak for a long time, and he didn't come back to his senses until Zhu Yu walked out of Fengtian Hall for a long time.

"Go to Jiangxi Jinxian to spread our will, let them continue to change!"

"Yes!"

Zhu Yu sent Liu Jiu to Chunhe Palace from time to time to inquire about the news of Jiangxi Jinxian, but there was news back, but it was all cruel news that made him realize the reality, and he changed and abolished four stoves in more than three months.

Big brother, believe me again, he can't say this kind of thing.

He was a little panicked, so he planned to go out of the palace to see Liu Ji.

However, before leaving, I remembered another person.

In the small courtyard of the Liu family, a slender shadow, squatting by the well, holding the stick in her thin hands, standing on a high place and looking down, the shape of the body is like a white swan.

Zhu Yu decided to call her Little White Goose in the future.

Liu Yun saw a reflection from the well, the reflection was looking at her, and when she saw it clearly, "Why is the big liar in the well?" ”

Realizing that something was wrong, he turned around sharply.

"You dare to insult Gu, Nine, what crime should you be punished?"

"Ah, His Royal Highness is the son of His Majesty, at least he must engrave words on his face, and then send him to Yunnan to fill the army, right?" Liu Jiu said with a smile.

Liu Yun took a step back, her hand in the position where she felt safe, "I'...... I didn't scold you. ”

Mother Yang had already told her that His Royal Highness the King of Qi wanted to give you a robe, and she was afraid that you would not accept it before she said such a thing, she was going to apologize to Zhu Rong, but when she saw Zhu Rong bullying her, she didn't want to say it.

"Lone said last time that he wanted to take you to see Mr., and this time I came to fulfill my promise, but you change into that dress first."

"I don't want it."

"Do you want to see Mr. anymore?"

Liu Yun pursed her lips, mist gradually gushed out from her eyes, and when she appeared in front of Zhu Yu again, she had already changed into that cyan robe, and her appearance had improved by a few grades.
