“It’s out.”

"Get the mold."

Just as Su Lie was struggling with Li Muyun's attention, the steel mill not far away, or the steelmaking room was more suitable. A shout came from the inside, and then he saw a worker rushing out of the inside, grabbing the mold made of clay on the ground and running back in a hurry.

When Wang Jie was shouted by that voice, he didn't bother with Li Muyun, so he left him and Su Lie and rushed in.

The workers' habits are called iron, but Wang Jie and the others know that the steel is made there, and the things burned are countless times stronger than iron.

After all, an ordinary iron knife only sells for less than a hundred cents, while a steel knife costs about two or five cents. This is no longer a ten-fold gap, but a twenty or thirty-fold gap.

...

‘Bang’ The mold that Li Muyun made in advance was lifted out of it, radiating heat.

"Is this what you mean by armor-breaking arrow?" Su Lie took a look from afar. He knew that this thing was very hot now, so he didn't lean over, but just stretched out his feet and pointed it with his toes.

"Yes, you can take it out and use it after it cools down a little later." Li Muyun said with a smile.

"Are you too expensive? If you really use this thing to fight, I'm afraid the Tang Dynasty will be poor in just a few years." Su Lie looked at the mold waiting to cool on the ground and decided to have a good talk with Li Muyun.

"Isn't war just about making money? Besides, the armor-breaking arrows are only used when the enemy has armor. If you are against some grassland herders, just use some of these arrows and insert them into the wooden pole." Feeling Su Lie's formality, Li Muyun finally became a little normal.

"Why do you have to use this kind of arrow? Is it bad before?" Su Lie frowned, still feeling that Li Muyun was a little unreasonable.

"The arrows used to be good, but the destructive power is too small. It will be fine if you pull them out and sew them after being shot. But now we have a three-edged barb. After being shot, we can only take them out from the other end, and the wounds are much more difficult to deal with than the wounds caused by flat arrows." Li Muyun raised the military sting in his hand and explained to Su Lie the practicality of the triangle arrow, from theory to practice.

Su Lie listened attentively, surprised that his brother-in-law was so researching about murder, and asked with some confusion: "Is it meaningful that you said so much? Is it worth the few onions under your hands? Is this something that only you can use?"

"Who said I wanted to use it myself? I kept it for sale, one or two cents."

"Then you should keep it yourself. Just your price, ten arrows are enough to buy a bundle in the court." Su Lie sneered at Li Muyun's offer and said disdainfully: "I think you are crazy about money, and don't consider the actual situation."

"The actual situation? The actual situation is that I use this thing to pay the bill. I will pay one million yuan in five years. No one has stipulated that I must get real money and silver." Li Muyun retaliated against Su Lie, and looked at him as if he was looking at a local bully. Old Su was so angry that he blew his beard and said with a glaring look: "Don't forget, you borrowed money from His Majesty's private treasury."

"That's only 200,000 yuan!" Li Muyun pointed to the direction of the mountain village in the distance: "Also, I didn't say that I would definitely pay His Majesty the money. His Majesty might also take things to cover the tent. After all, it would cost money for me to rebuild the Tai Chi Palace, so I can't let me do it in vain."

"Then according to your wishes, you don't plan to pay back the money?" Su Lie's face was a little heavy.

If Li Muyun really didn't plan to pay back the money, if Li Shimin pursued it, it would be a serious crime of deceiving the emperor, and Su Lie would never let such a thing happen.

But Li Muyun obviously had other plans, shook his head and said, "Repaying money and returning things are actually the same thing. As long as your Majesty is satisfied, I don't care about how to repay the money. Moreover, brother, this matter is very deep, so don't ask too much."

Li Muyun originally wanted to tell Su Lie the whole thing, but then he thought about it and let it go. After all, it was a bad thing for Li Shimin to get money from the treasury to his own private treasury, and it would not be good for anyone if it was spread.

Su Lie was hesitant about Li Muyun's words, but in the end he didn't say anything more. He just looked at him deeply and advised: "It's good that you know it. Don't forget that you are no longer alone now, so you have to think more about it."

"Don't worry, brother, I know what's going on." Li Muyun smiled, then looked at the mold on the ground and said, "It's almost time, it's time to get cold, let's open it and take a look." After that, Li Muyun waved to several workers not far away.

...

The armor-breaking arrow is actually not special, it looks not much different from the fine steel bars of later generations.

However, the triangular arrow looks chilling. After polishing it a little, the cold light shines. Without having to test Su Lie, you will know that this thing is a weapon for killing people.

"How is it? Is this thing good?" Li Muyun fiddled with the more than ten branches of all steel on his hand and squeezed his eyes at Su Lie.

"Hmph!" Su Lie snorted and took one from his hand: "Things are good things, but they are too expensive and are not practical."

Yes, this thing is indeed not practical. The Tang Dynasty is not rich enough to use crossbow arrows made of all steel, which means that this thing is of no use after it is made.

After all, this thing is not an atomic bomb, and one can kill a large number of people if thrown out.

No matter how powerful this thing is, it is just killing one person. Ordinary crossbow arrows can also be used. In this way, crossbow arrows made of all steel become decorations.

However, Li Muyun obviously has his own plans. If the all-steel crossbow arrow is not available, then create an arrow. The destructive power of the triangular pyramid is definitely not comparable to that of ordinary arrows. Even if Li Shimin comes, he has to admit this.

At this moment, Wang Jie also ran over excitedly, holding two fist-sized steel ingots in his arms, and shouted while running: "Mu Yun, this is really steel, really yes."

Yes, of course this is steel, Li Muyun glanced at Wang Jie speechlessly.

The blast furnace produces pig iron because the iron ore is neutralized with coke in the blast furnace and contains a lot of charcoal.

But open furnaces are different. In the open furnace, the pig iron does not come into contact with the fuel at all. It just melts at the high temperature of the flame. After the neutralization of some source materials, the carbon component is largely eliminated, so steel is formed.
