Kong Jing's eyes lit up, and he hurriedly stepped forward: "What, mold?" What do you mean? ”

Liu Yu smiled slightly: "Master Kong, have you ever known how this money is made?" ”

Kong Jing muttered, "Minting money? I really don't know, I can only forge armor and build weapons, and I really don't know how to get this money. ”

Liu Yu nodded: "That friend of mine, proficient in all kinds of mechanical techniques, coin making methods, he said, since ancient times, coins have been minted through the mother money, to make money fan, and then pour copper juice into these money fan, that is, you can get coins." Otherwise, those five-baht coins, Kaiyuan Tongbao, can the words on them be carved out one by one? ”

Feng Qian suddenly realized and nodded: "Yes, with so much money, it is impossible to type out like a piece of armor." So, how is the money made? ”

Liu Yu Zhengse said: "The coinage is to melt the copper ore to form copper juice, and then cast it into the money fan made of the mother money, these money fans are some soil casting molds, smeared on the mother money with wet mud, and then dried, after drying, take out the mother money, then the words printed on the mother money, the engraved things, become the formula, stay on this dry soil money model. Later, you only need to pour the copper juice into these coins, and after the copper juice is condensed, take out these copper pieces, and it is a coin. ”

Kong Jing's eyes widened: "It turns out that the money is cast like this!" No wonder money is minted so quickly. But how long will this money fan last? And how to cover it? ”

Liu Yu smiled slightly, and took out a copper coin from his arms: "The copper coin has two sides, one is the yin side, the other is the yang side, when the money is minted, the clay is first covered to half the thickness of the money, completely glued to the yin side, and then take out the copper coin, and then do this to make the yang side of the money fan, you can leave the gap a little bigger, so that the copper juice can be poured into the copper juice, so that after the two-sided mold is done, you only need to pour the copper juice into one side until it overflows, and then close the other side, after the copper juice on both sides solidifies, it is a copper coin." ”

Speaking of this, Liu Yuzheng said: "In the land of Yizhou, there is more iron and less copper, and the Shu Road is difficult, and very few copper ores can be transported in, so in Yizhou, they are all cast iron money, not copper money." Mao Zhengzheng and Sergeant Feng are both from Yizhou, so they should know this. ”

Maoqiu laughed: "Exactly, our Yizhou, as well as Liangzhou in the Hanzhong area in the north, all use iron money, not copper money, which is different from other places." It should also be the method of minting money that you said! ”

Liu Yu said with a smile: "So, as long as we come up with a mold, Qian Fan, we can use a similar method to create a nail piece, and there is no need to engrave on these nail pieces, then it is easier to do it, and directly cast it into a similar nail leaf fan, you can mass produce these stainless steel nail leaves." Master Kong, you don't need to use that kind of harsh punishment to force people to work anymore.

”

Kong Jing said with a smile: "If you can save effort, of course use the labor-saving method." But where did this clay come from? ”

Liu Yu hooked the corners of his mouth: "The fat man who used to join the army in the baggage camp Liu Muzhi is good at this, I listened to what he said, or we called him here and let him be in charge of this matter, he will definitely get twice the result with half the effort!" ”

Kong Jing laughed so that the wrinkles at the corners of his eyes were trembling: "I said that Liu Fat Man is good at this matter, okay, I'll go find him now!" ”

Liu Yu shook his head: "No, let's go, this dead fat man is the most familiar with me, if I speak, he will definitely not refuse." By the way, Master Kong, what are your good dishes in the land of Minyue? ”

Two hours later, it was noon, Liu Muzhi, who was dressed in a scribe's robe, shook a pu fan in his hand, shook his head with a wry smile on a small barren hill outside the blacksmith camp, and said to Liu Yu standing beside him: "I said that I am a slave, fat man, I finally escaped from this big furnace, why did you pull me back again?" ”

Liu Yu said angrily: "You kid is not kind, you obviously know this kind of money model, the method of minting coins, but you don't teach Kong Jing to use it, what is this?" ”

Liu Muzhi hooked the corners of his mouth disdainfully: "This kid is very arrogant, he doesn't have the attitude of a humble corporal at all, relying on his family's ancestral blacksmith skills, he is coaxing, and he wants me to make iron for him, hmph, I am a scholar, how can I do this kind of rough work?" Besides, if he really taught him this, he still had to circle me around those iron stoves every day and let me give him a fan. ”

Liu Yu sighed: "You don't always have to eat idle meals in the army, you always have to play your role." You can make armor in a faster way, but you don't, why is that? ”

Liu Muzhi said with a smile: "My talent should be to strategize and win thousands of miles, this small blacksmith shop is too condescending for me." If I help him out of the nail leaf here, they will find a way for me to get another hundred refining knives and other things, endlessly, annoying and annoying, and hot to death. ”

Speaking of this, he paused: "Besides, the food here is so poor, you see how thin I have become." Recently, after being transferred to the Marshal's Mansion of the Chinese Army, I was finally able to eat well. ”

When Liu Muyi talked about eating, his eyebrows immediately fluttered, and even his index finger began to move.

Liu Yu shook his head angrily: "Eat, eat, eat, know how to eat." I'm really convinced. As he spoke, he took out a lotus leaf wrapped in something from behind him as if he were juggling, and said with a smile: "What do you think this is?" ”

Liu Muzhi's nose twitched, and he said to himself: "I seem to smell the fragrance of chicken." ”

He grabbed the lotus leaf bag, and hurriedly opened it, only to see a whole puff pastry roast chicken, which suddenly caught his eyes.

The fat on Liu Muzhi's face was beating, and he tore off a chicken thigh with one hand, and laughed: "It's actually roast chicken, oops, it's great." He was about to put this roast chicken in his mouth, but he frowned, licked the skin on the chicken legs, and wondered: "What kind of taste is this, why have I never eaten it?" ”

Liu Yu said with a smile: "This is the unique method of cooking chicken in Minyue, it is said that the spices smeared on the chicken, but from the land of the South Seas, what is it called, what is the ambergris in the sea, a total of hundreds of precious spices, made of this Baiwei chicken." Kong Jing himself couldn't bear it. ”

Liu Muzhi laughed, took a bite, closed his eyes and savored it, while nodding his head and saying, "Good chicken, good chicken, it's really delicious." That's it, for the sake of this chicken's face, and for the sake of your brother Jinu to get out of this blacksmith shop as soon as possible and return to the combat unit, I will teach you this method of molding. ”

Speaking of this, the corners of Liu Muzhi's mouth hooked strangely, and he said mysteriously: "Tell you about my latest research results, Qian Fan is outdated, and it will be the world of sand turning in the future!" ”
