Chapter 263 Steel


"The iron is out.

"Bring the mold."

Just when Su Lie was entangled in the problem of Li Muyun's attention, the steelmaking mill not far away, no, or the steelmaking room was more suitable, there was a shouting sound from inside, and then he saw a worker rushing out from inside, grabbing the mold made of clay on the ground and running back in a hurry.

Wang Jie was called by that voice, and he didn't care about talking to Li Muyun, so he left him and Su Lie and rushed in.

The habit of workers is called iron, but Wang Jie and they all know that what is smelted there is steel, and what is burned is many times stronger than iron.

After all, an ordinary iron knife is only sold for less than 100 yuan, but a steel knife is sold for about two or five times, which is not a tenfold gap, but a twenty or thirty times gap.

The mold that Li Muyun had made in advance was lifted out of it, steaming hot.

"This is what you said about the armor-piercing arrow" Su Lie glanced at it from a distance, he knew that this thing was very hot now, so he didn't lean over, just stretched out his foot and pointed with his toes.

"Yes, you can take it out and use it after it cools down for a while."

Li Muyun said with a smile.

"Aren't you too expensive, this thing is too expensive, if you really use this thing to fight, I'm afraid that within a few years, Datang will already be poor."

Su Lie looked at the mold on the ground that was waiting to cool, and decided to have a good talk with Li Muyun.

"Isn't fighting a war just about making money, besides, armor-piercing arrows are only used when the enemy has armor, if for some grassland herdsmen, just get some of these arrows and insert wooden poles."

Feeling Su Lie's formality, Li Muyun was finally a little more normal.

"Why do you have to use this kind of arrow, isn't it good before" Su Lie frowned, still feeling that Li Muyun was a little unreasonable.

"The previous arrow was good, but the destructive power was too small, and it would be fine to pull it out and sew it up after the arrow, but now we have a three-edged barb, and the arrow can only be taken out from the other end after the arrow, and the wound is much more difficult to treat than the wound caused by the flat-headed arrow."

Li Muyun raised the military thorn in his hand and explained to Su Lie the practicality of the triangular arrow, from theory to practice.

Su Lie listened attentively, surprised that his brother-in-law had studied murder so well, and asked a little puzzled: "You said so much, does it make sense to use these green onions under your hand?"

"Who said I wanted to use it myself, I kept it for the money I sold, and I paid two pennies for a stick."

"Then you better keep it for yourself, at your price, ten arrows are enough for the court to buy a bundle normally."

Su Lie scoffed at Li Muyun's offer, and said with disdain: "I think you are crazy about money, and you don't think about the actual situation." ” "The actual situation is that I take this thing to the account, and I will pay one million yuan in five years, and no one stipulates that I must take real money."

Li Muyun returned the color to Su Lie, looking at him with a look like he was looking at a turtle, the angry old Su blew his beard and glared: "Don't forget, you borrowed money from His Majesty's private treasury." ” "That's only 200,000 yuan" Li Muyun pointed in the direction of the cottage in the distance: "Also, I didn't say that I would definitely pay back Your Majesty's money, Your Majesty may also take things to pay the account, after all, it costs me money to rebuild the Taiji Palace, and I can't let me do it in vain." ” "Then according to your meaning, you don't plan to pay back this money" Su Lie's face was a little heavy.

If Li Muyun really didn't plan to repay the money, in case Li Shimin was held accountable, it would be a big crime of bullying the king, and Su Lie would never let such a thing happen.

But Li Muyun obviously had other plans, shook his head and said: "Paying back the money and returning things are actually the same thing, as long as Your Majesty is satisfied, I don't care what way to repay the money."

And, big brother, this matter is very deep, so don't ask too much. ” Li Muyun originally wanted to tell Su Lie about the whole thing, but after thinking about it, he still forgot it, after all, Li Shimin got money from the treasury to his own private treasury, and it was not good for anyone if it was passed on.

Su Lie was a little hesitant by what Li Muyun said, but in the end he didn't say anything more, just looked at him deeply and persuaded: "It's good that you know it in your heart, don't forget, you are not a person now, you have to think more about it." ” "Don't worry, big brother, I know it in my heart."

Li Muyun smiled, then looked at the mold on the ground and said, "It's almost time, this thing should be cold, let's open it and take a look."

With that, Li Muyun beckoned to a few workers not far away.

Armor-piercing arrows are actually nothing special, and they look not much different from the thin steel bars of later generations.

It's just that the triangular pyramid-style arrow makes people feel chills when they look at it, and after a little polishing, the cold light is shining, and they don't need to test Su Lie to know that this thing is a weapon to kill.

"How about this thing, isn't it" Li Muyun fiddled with the more than ten all-steel triangular arrows in his hand, and squeezed his eyes at Su Lie.

"Hmph" Su Lie snorted and took one from his hand: "The thing is a good thing, but the cost is too high and not practical." ” Yes, this thing is indeed impractical, and Datang is not rich enough to use all-steel crossbows at the moment, which means that this thing is useless after it is made.

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

No matter how powerful this thing is, it is just a matter of killing a person, and ordinary crossbow arrows can do the same, so that a crossbow made of all-steel will become an ornament.

However, Li Muyun obviously has his own plans, the all-steel crossbow arrow is not available, so build an arrow, the destructive power of the triangular pyramid is definitely not comparable to ordinary arrows, even if Li Shimin comes, he has to admit it.

At this moment, Wang Jie also ran over in a hurry, holding two fist-sized steel ingots in his arms, and shouted as he ran: "Mu Yun, this is really steel, it really is." ” 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, which contains a large amount of carbon.

However, the open-hearth furnace is different, in the open-hearth, the pig iron is not in contact with the fuel at all, it is only melted at the high temperature of the flame, and after the neutralization of some source materials, the carbon component is eliminated in large quantities, so steel is formed.

It's a pity that no one in Datang understands this, although there are some practices in this era that are the same as carbonization and decarbonization, but everyone only knows what it is, and ignorant and indiscriminate refining, and the things that are refined in the end are sometimes good and sometimes bad, and there is no certain standard at all
