Liu Yu said with a smile: "If the Baili Steel Knife really becomes soft around the fingers, wouldn't it have the toughness of Baili Steel and the softness of wrought iron, which can be soft or hard, making it invincible in the world?"
Kong Jing smiled slightly, and an intriguing light flashed in his eyes: "This is the lifelong pursuit of every swordsmith. Maybe, we can make such a magical weapon!"
Liu Yu nodded: "Then this piece of armor doesn't need to be made with hundreds of steel."
Kong Jing said: "Yes, although it is an exaggeration to make a hundred steels, it still needs to be hammered repeatedly for at least sixty or seventy times until the weight does not decrease. It is extremely expensive both in terms of material consumption and labor. Five Ten kilograms of iron ore, iron fine powder, and charcoal powder can produce about one kilogram of steel. If even the armor plates of ordinary soldiers need to be made of steel, then the country can only support a few thousand troops."
Liu Yu laughed: "So, we can only get a few of these to equip the generals. The other sergeants can only wear ordinary armor?"
Kong Jing shook his head: "For ordinary armies, it's good to wear leather armor. According to the military system of the Jin Dynasty, only 60% of combat sergeants wear leather armor. Elephant archers can only wear cloth armor, or even no armor." , only wearing coarse cloth. The Beifu Army is already equipped with sharp armor, so we will ensure that all front-line combat troops have armor to wear, while the Tiger Troops must be equipped with fine steel armor."
Liu Yu frowned: "Stainless Steel Armor? How do you define this fine steel?"
Kong Jing walked to the side of a red basket and looked at a particularly eye-catching small basket. There were densely packed armor blades in the basket. He took out one from it and handed it to Liu Yu: "Look, this armor leaf , how is it different from what you just saw?"
Liu Yu took the piece of nail and carefully rubbed it in his hand while observing. He felt that the tentacles of this piece of nail were smooth, not like the one just now. It felt a little rough, and the weight was heavier than before. The armor pieces, which cost about half a penny, were slightly lighter, only about eight baht. (One tael and twenty-four baht, each plant weighs ten wheat grains, which is about 0.65 grams)
Liu Yu weighed the piece of nail and said: "It seems that this piece of nail is lighter and smoother than before, and it is also..." He said, using two fingers to bend it, The piece of armor, the piece of armor just now, he used three points of force on his hand like this. After folding, he could bend the piece of armor at once, but this piece of armor, he used the force just now, but it didn't move at all. It wasn't until he increased his hand strength to 50% for the second time that the piece of armor began to bend slightly.
Liu Yu smiled and said: "It's much harder than the previous one. It seems that it can not only prevent arrows, but also the swords and stabs of ordinary soldiers at close range. Is this fine steel?"
Kong Jing nodded, took the piece of armor leaf, threw it back into the red basket, and said: "Yes, this is fine steel. It is the final product after forging it for fifteen times. Although it is not as good as It takes hundreds of years to make steel, but it is also an extremely excellent steel. The armor and combat equipment produced are generally equipped for the elites of the Chinese army, or for the nephews of generals, especially for the cavalry, which is the assault force of the entire army."
Murong Nan's appearance suddenly appeared in Liu Yu's mind, and he asked: "The Xianbei people in the north are equipped with armor and cavalry. Are these armored horses wearing these fine steel armors?"
Kong Jing frowned: "The Murong family has been in Liaodong for a long time, and their iron smelting skills are very high. The armor-making methods they use are not exactly the same as ours. I don't know how to define the things they create, but in my opinion Come on, its strength is even higher than that of Baidu Steel!"
Liu Yu opened his eyes wide: "Is it so powerful?"
Kong Jing sighed: "The Murong family's armored war horses are invincible. It's not a boast. Of course, only their own tribe has the secret method to build fine armor, while the servant tribe has no right to equip fine armor and can only equip ordinary iron armor. It can be said that the Murong clan has one hundred thousand cavalry, but the only one who is truly powerful is the three thousand armored cavalrymen of the headquarters."
Liu Yu nodded: "But if these three thousand cavalry are invulnerable and wear armor that is more powerful than a hundred steelmaking, it will be troublesome. We really have to think of a way to deal with it."
Kong Jing smiled slightly: "If you know how Murong's armor is made, you may have a chance to crack it. However, now we still think about how to make fine steel armor for our troops. Liu Yu, these steels were made by slaves Let us prepare it, you are strong, all you have to do is forge the armor pieces."
Liu Yu frowned: "Forged armor? What do you mean?"
The fur ball on one side said: "The armor pieces are made of cold forged steel blocks, which are different from those that need to be red-hot, deformed, and then re-forged into the shape we want. So, it is completely necessary. Rely on strength to hit these already formed iron blocks and turn them into pieces of armor."
As he spoke, he pointed to a large basket next to him, which was full of small pieces of fine steel, and said: "These are the original pieces of armor. What you have to do is to This raw block is beaten into the kind of fine steel armor you just saw."
Liu Yu nodded: "I understand. I see that the surfaces of these armor plates are very smooth. This cannot be done by just hitting them with a hammer. They need to be polished, right?"
Kong Jing said sternly: "Yes, these small pieces of fine steel were poured out bit by bit by the craftsmen when they were in the state of molten steel. They come in various shapes and require strong men to smash them with a hammer. After smashing it to look like a piece of armor, then a special person will handle the surface, polish it, drill holes, etc. Liu Duizheng, you only need to hammer it."
As he spoke, he picked up a large hammer that weighed thirty or forty kilograms and handed it to Liu Yu: "Liu Captain, it's up to you."
Liu Yu nodded, suddenly thought of something, and said: "I see that when these armor pieces are made, they all need to be slightly curved, and they are not completely flat. So, do you need a special anvil to make them?"
Kong Jing was stunned for a moment, then smiled and said: "No, that one was hammered slowly with a small hammer. Of course, you don't need to do it. It's still for the polishing and drilling craftsmen. You only need to knock the steel Just smash it into a roughly rectangular shape. This is a laborious task."
Liu Yu suddenly shook his head: "Master Kong, maybe we have a better way to form the armor directly!"
Kong Jing asked curiously: "What's a better way? Do you have any ancestral secret skills?"
Liu Yu smiled "hehe": "I know a fat man. He has read many books. When it comes to blacksmithing, he once said that instead of cold forging, it is better to let the iron be formed when it is in a molten state. As long as it is good enough, Mold, you can do it!" chapter;
