Eight Hills in the Eastern Jin Dynasty

.

At night, Guangling City, Beifu Bingshuai Mansion.

Inside the compound, there were non-stop ordering sergeants hurriedly, and people such as documents, holding a lump of official documents, or holding bamboo slips and silk cloth, quickly walked away, a team of patrol sergeants, Perseverance, three steps and one whistle, five steps and one post, the atmosphere is not generally serious.

Inside a box room, Liu Muzhi was gorging on a bowl of shredded chicken with chopsticks. He took the last bite, licked up the remaining residue on the bowl, closed his eyes, and breathed a sigh of relief. , Seems to be aftertaste the beauty on the tip of the tongue just now.

Liu Yu sat next to him and ticked his mouth: "Dead fat man, you have eaten my one month's military pay for this meal. Okay, I should say it."

Liu Muzhi opened his eyes and sighed in a sense: "It would be nice if I had this soup with soup every day."

Liu Yu smiled and said, "If you have made merits in battle, promoted your rank, and won the prince, you are still afraid that if you don't eat, sometimes you will be smart, but sometimes you will feel stupid than you think."

Liu Muzhi shook his head: "I'm not a small army. There are two or three hundred of my rank here in the Chinese army. It's not like a Chinese soldier like Wang Yi joined the army. I'm afraid of giving advice and turning. Come to me. "

Liu Yu frowned: "Why, Xuan Shuai called you up to prevent you from suggesting something"

Liu Muzhi sighed: "There is no war now, what good policy can be offered since our army was suddenly dispatched five days ago, and the Qin army withdrew from the army for fifty miles, and after solving the three siege, General Tian's headquarters followed the southern withdrawal Even the soldiers and civilians of Pengcheng have been evacuated. Now the Qin army has occupied the entire Huaibei, and the war has entered a phase of stalemate. No one dares to act rashly. What else can I offer. "

Liu Yu smiled slightly: "Isn't this the way you and I discussed that day? Since Xuanshuai used this, he will use our future strategies."

Liu Muzhi wiped his mouth and said in a straight voice: "Junior, this advice is based on the timing. The last time our army was defeated, Xuanshuai needed to open his mouth and listen to many opinions, and those other families also did not. Dare to contain it at this time. But this time the crisis was temporarily alleviated, and families like the King Kuaiji and the Wang family began to slap their hands again. Those with higher official positions are mostly children of the family. Eight tongues, to show your role, you and I imagine that it would be difficult to make such a speech last time. "

Liu Yu sneered: "Even if you can't speak, you can see a real chapter on the battlefield. The next thing is to train for a few months. After fighting out the elite soldiers, the Qin army is wiped out. Today, I am doing this. Here comes, well, not much, let's talk about how to build this sword. "

Liu Muzhi put away his smile and said straightly: "Slave, I can't really help you with this matter. The nails can be mass-produced by casting money, but the weapons are not. This is not a method. The problem is the problem of resources. "

Liu Yu frowned: "Is it enough that there are not enough steel and Bai Steel"?

Liu Muzhi nodded: "Yeah, you want to use a knife, not a spear, this knife is made in one piece, unlike the spear, you just need to change the tip, and Kong Jing said well, even if The overall construction, the blade is too hard, and it is easy to break. Therefore, the treasure knife is always extremely expensive. Even if it is Gongsun Wanghou, there are only one or two. It ’s not that I do n’t want to help you, but I ca n’t help. ”

Liu Yu was speechless for a while. Today he came full of hope and wanted to get an answer from Liu Muzhi, but he didn't expect it would be the result. He sighed: "If you don't know that fat man, you'll be hurting me. so much."

Liu Muzhi laughed: "Don't you have paid for these foods before you came to me? Don't you give me your own food? Anyway, you don't have any requirements for food. It's better for me . "

Liu Yu gritted his teeth: "It doesn't matter if you give it to you, but this can't be done. It really makes me unable to explain. I only created fine armor, but no sharp edge. I can't sweep the thousand troops on the battlefield. I am always unwilling. where."

Speaking of which, he ticked the corner of his mouth: "If the wrought iron is very soft, can you think of a way, only use 100% steel in the blade layer, but the back of the blade is wrought iron?"

Liu Muzhi sighed: "Someone has thought about this method for a long time. No one can make it for hundreds of years because the wrought iron is too soft. Although it has just been easily broken, it is as soft as wrought iron, but it is not. practical."

Liu Yu nodded thoughtfully: "Since steel is formed by continuously adding carbon powder in wrought iron, can we also add carbon powder in wrought iron to make it harder?"

Liu Muzhi said with a smile: "This idea is pretty good, but it's just a mistake, but if you want to pour 100 steelmaking on the wrought iron, when you add charcoal powder to the wrought iron, it is also the same If you add it to Bai Steel, it will soften the hard steel. After all, the various additives in www.ltnovel.com ~ cannot be changed casually, just change it. It's a pig iron. "

Liu Yuchang sighed: "Unexpectedly, this matter is so troublesome, even you have nothing to do!"

Liu Muzhi nodded: "But you can try this idea. Although the wrought iron is soft, there are a lot of carbon powder in the steelmaking. Maybe if it is well controlled, you can put some carbon in the steelmaking. Powder, slowly infiltrated into the wrought iron. "

Liu Yu's eyes lit up and quickly said: "I seeped into the wrought iron, you mean, do you mix two kinds of steel juice together?"

Liu Muzhi shook his head: "No, you can't simply mix them together. What you need is a blade of steel, and the back of the blade is wrought iron with carbon powder, not a whole mix of steel. It's like a wrought iron knife. This kind of knife is not hard, soft or soft. It's no different from ordinary pig iron. It's definitely not what you want. So, this requires you to master the timing of quenching. It is not soft, and when the wrought iron has just been infiltrated and the carbon powder is hardened, it is quenched at once. Only then can you get the knife you want. "

Liu Yu gritted his teeth: "So, only I kept trying."

Liu Muzhi stretched a lazy waist and hiccuped: "Slave, all things in this world, there must be one to do between thinking and getting. The knife you want is for thousands of years. The skilled craftsmen all want to make it, but it is always so poor, you are not a professional blacksmith, but only a few days of ironing, you can think of so much, maybe, God will really favor you and let you invent What about this kind of sword that cuts iron like mud. "

Liu Yu stood up, turned and walked away: "Then trust you, I will do it now."

Liu Muzhi's voice suddenly sounded in the back: "Wait a minute, there is something else."
