Kong Jing's eyes lit up and he quickly stepped forward: "What, mold? What do you mean?"
Liu Yu smiled slightly: "Master Kong, do you ever know how this money was made?"
Kong Jing murmured: "Creating money? I really don't know. I can only cast armor and make weapons. I really don't know how I got this money."
Liu Yu nodded: "That friend of mine is proficient in various mechanical techniques and coin-making methods. He said that since ancient times, money has been minted through mother money, making money molds, and then pouring copper juice onto these coins.
Fan Li, that is, you can get coins. Otherwise, could the characters on those five-baht coins and Kaiyuan Tongbao be engraved one by one?"
Feng Qian suddenly realized and nodded: "Yes, it's impossible to make so much money one by one like armor pieces. So, how is the money made?"
Liu Yu said seriously: "To make money is to melt copper ore to form copper juice, and then cast it into money molds made of mother money. These money molds are clay molds, and they are smeared on the mother money with wet mud.
and then dry it. After drying, take out the mother coin. Then the printed words and engraved things on the mother coin will become a fixed form and remain on the dry earth coin model. Later, you only need to pour the copper juice into it.
These coin molds, after the copper liquid condenses, take out these copper blocks, and they will become a coin."
Kong Jing opened his eyes wide: "It turns out that this is how money is minted! No wonder the money is minted so fast. But how long can this coin mold be used? And how to cover it?"
Liu Yu smiled slightly and took out a copper coin from his arms: "A copper coin has two sides, one is the yin side and the other is the yang side. When casting the money, first cover the clay to half the thickness of the coin and completely stick to the yin side.
, then take out the copper coin, and then make the coin mold with the positive side in this way. You can leave the gap a little larger for pouring copper juice. In this way, after the molds on both sides are made, you only need to pour copper juice into one side until it overflows, and then
Close the other side, and after the copper juice on both sides solidifies, it becomes a copper coin."
Speaking of this, Liu Yu said seriously: "The land of Yizhou has more iron and less copper. In addition, the road to Shu is difficult, and very few copper ores can be transported in. Therefore, in Yizhou, all coins are made of cast iron, not copper coins. Mao
Both Duizheng and Sergeant Feng are from Yizhou, so they should know this."
Maoqiu laughed: "Exactly, we in Yizhou and Liangzhou in the Hanzhong area in the north use iron coins instead of copper coins, which is different from other places. They should also use the method of casting money you mentioned!
"
Liu Yu said with a smile: "So, as long as we get the mold, Qian Fan, we can use a similar method to make armor pieces. There is no need to engrave on these nail pieces, so it will be easier. We can directly cast them into similar armor leaf models."
, you can mass-produce these fine steel armor leaves. Master Kong, you no longer need to use that kind of harsh punishment to force people to work."
Kong Jing smiled and said: "If you can save labor, of course you should use labor-saving methods. But where do you get these clays?"
Liu Yu curled up his lips: "The fat man Liu Muzhi who used to be in the supply camp joined the army and was good at this. I listened to what he said. How about we call him here and let him take charge of this matter?"
Get twice the result with half the effort!”
Kong Jing smiled so hard that the wrinkles at the corners of his eyes trembled: "I told you that Fatty Liu was good at this matter, okay, I'll go find him now!"
Liu Yu shook his head: "No, let me go. This damn fat guy knows me best. If I ask, he will definitely not refuse. By the way, Master Kong, what are you good at in Fujian and Yue?
vegetable?"
Two hours later, it was already noon. Liu Muzhi, dressed in a scholar's gown, was shaking a cattail leaf fan in his hand. He shook his head with a wry smile and said to Liu Yu who was standing next to him on a small barren hill outside the blacksmith camp.
: "I said, slave, Fatty, I managed to escape from this big furnace with great difficulty, why did you bring me back again?"
Liu Yu said angrily: "You are not kind, you know this kind of money and the method of minting it, but you don't teach Kong Jing how to use it. What does this mean?"
Liu Muzhi curled his lips in disdain: "This boy is very arrogant, and has no humility at all. He relies on his family's ancestral blacksmith skills and is so arrogant that he wants me to blacksmith for him, huh, I
But how can a scholar do such a menial job? Besides, if I really taught him this, he still wouldn’t have to put me next to those iron stoves every day and ask me to give him a class."
Liu Yu sighed: "You are not just a freeloader in the army, right? You have to play your role. You can obviously make armor faster, but you don't use it. Why is that?"
Liu Muzhi smiled and said: "My talent should be strategizing and winning thousands of miles away. This small blacksmith shop is too unqualified for me. If I help him fight the Jiaye here, they will find a way
Let me continue to work on things like the Hundred Refinement Swords, it will be endless, it will be annoying to death, and it will be hot to death."
Having said this, he paused: "Besides, the food here is too bad. Look how thin I've become. It's only after I recently transferred to the Commander-in-Chief's Mansion that I can finally eat well."
When Liu Muzhi talked about food, his eyebrows immediately lit up and his index finger began to move.
Liu Yu shook his head angrily: "Eat, eat, eat, you know how to eat. I'm really convinced by you." He said, magically took out something wrapped in lotus leaves from behind, and said with a smile: "You
Look what is this?"
Liu Muzhi's nose twitched and he said to himself: "I seem to smell the aroma of chicken."
He grabbed the lotus leaf bag and hurriedly opened it, only to see a whole crispy roasted chicken suddenly caught his eye.
The fat on Liu Muzhi's face was pulsing. He tore off a chicken thigh in one go and laughed loudly: "It's actually roasted chicken. Oops, it's so good." He was about to put the roasted chicken in his mouth.
He frowned, licked the skin of the chicken leg, and asked, "What does this taste like? Why have I never tasted it before?"
Liu Yu said with a smile: "This is a unique method of cooking chicken in Fujian and Yue. It is said that the spices applied to the chicken are brought from Southeast Asia. What is it called cinnamon, and what ambergris from the sea?
A total of hundreds of precious spices were used to make this Baiwei-style chicken dish. Kong Jing himself couldn't bear to part with it."
Liu Muzhi laughed, took a bite, closed his eyes and thought about it, while nodding his head repeatedly: "Good chicken, good chicken, really delicious. For the sake of this chicken, I also send slaves for you."
If I can leave this blacksmith shop as soon as possible and return to the fighting force, I will teach you this mold making method."
At this point, the corner of Liu Muzhi's mouth quirked up in a strange way, and he said with a mysterious face: "Let me tell you my latest research results, Qian Fan is outdated, and the world will be turned over in the future!"
