Datang romantic little landlord

The Zhanma Dao in the Song Dynasty originated from the Tang Dao, but the straight blade became curved.In this way, it is possible to avoid damage to the blade when chopping, and to maximize the power of the blade.

This applies to both the Arabian scimitar and the Japanese samurai sword.

"Liben, take a look at the shape of the sword as a teacher. Is it possible to make it like this?"

Yan Liben carefully looked at the drawing of the sword that Li Wangyou drew for a long time, but he was a little unclear, so: "Master, it can be made, but why is the blade curved? What's the benefit?"

It's hard for Li Wangyou to explain his question, so why should he teach Yan Liben a physics lesson?He also has to understand.

Li Wangyou knew that the curved blade was good for slashing and protecting the blade, but he couldn't tell the truth if he wanted to say one, two, three, four.

Regarding Yan Liben's question, Li Wangyou just put on a fake smile: "The Master said, 'Do what you say first, and then follow it.', Liben, go and forge this saber first, after testing it, you will definitely gain something. "

"Yes, the disciple has been taught." Yan Liben didn't know Li Wangyou's flamboyance, and thought that his teacher was teaching him, so he quickly bowed to salute.

After fooling Yan Liben, Li Wangyou didn't dare to talk about knives anymore, for fear of being timid, he could only drag him to talk about romantic things to pass the time.

After waiting for almost two hours, the tea was changed several times, and finally a galloping horse came from the Yellow Valley, and Li Wangyou knew that it was Niu Wu who had returned.

Coming with Niu Wu, of course, was Li Er, and the brigade of imperial guards behind him.

"Ziyou, I heard that your family's trilogy is here to report, and the coin has been minted?"

"Reporting to Uncle, that's exactly the case." Li Wangyou smiled and handed Li Er a freshly minted copper coin: "Please look at it, Uncle, this is the newly minted coin."

Li Er took the coin and looked at it carefully: "Hey, why are the handwriting and patterns on this coin so clear? This is what you said, a coin cast by water power? Tsk tsk, this coin is amazing, the workmanship It is so fine, compared with the official money minted before the court, it looks like private money. Come on, take me to see how this coin was minted."

Seeing Li Er's impatience, Li Wangyou smiled, and Yan Liben invited him into the Mint for a visit...

513 Another Business

For Li Er, the "earth turtle", using water power to push the twenty-stone hammer head to beat continuously by itself is extremely miraculous.

Witnessing copper coins being minted one after another with his own eyes, Li Er couldn't help being delighted.Even disregarding the dissuasion of Li Wangyou and others, he personally put the copper bar into the punching machine, and punched out a shiny Kaiyuan Tongbao by himself.

"Mi Tuo, take this Kaiyuan Tongbao carefully for me, haha, this is a coin that I forged with my own hands." Li Er proudly picked up the copper coin and threw it to Mi Tuo beside him.

Mi Tuo laughed so hard that he could hardly see his eyes. Holding the extremely ordinary Kaiyuan Tongbao in both hands, he bowed and said, "No! This Kaiyuan Tongbao cast by everyone is my Great Tang treasure and should be sent to Taimiao Zi The Extreme Palace accepts incense and offerings from the world."

"Sycophant!" Li Wangyou cursed inwardly.

This Mi Tuo really deserves to be the Minister of Internal Affairs, what he said made Li Er laugh out loud, and he nodded in agreement immediately.

The Taimiao mentioned by Mi Tuo refers to the Ziji Palace ten miles to the east of Luyi County, which is said to be the birthplace of Lao Tzu.

After Li Yuan recognized Lao Tzu as the ancestor of their old Li family, this Lao Tzu temple naturally became the Taimiao, and built palaces and palaces on this basis.

Mi Tuo, a bitch, actually urged Li Er to send this Kaiyuan Tongbao to the Taimiao Temple, which naturally made Li Er very satisfied.

Li Wangyou couldn't help but glared at Mi Tuo bitterly, secretly hating himself for not thinking of such a good idea.

The guy rolled his eyes, reached out his hand from the money bag on his waist, and took out a gold ingot weighing five taels, and handed it to Li Er.

"Uncle, why not try using this gold coin."

Li Er was stunned when he heard the words, but he didn't object. He reached out and took the gold ingot, and put it on the coin-making mold of the stamping machine.

Gold coins have actually existed in China since ancient times, but they are very rare.During the Warring States Period, Chu State had love gold, and the Western Han Dynasty had gold five baht.

Naturally, real gold coins are not directly made of pure gold, but need to be mixed with other metals to increase the hardness of gold coins.

However, Li Wangyou didn't intend to mint gold coins for circulation, so naturally he didn't care about that many.

This punching machine can even cast copper coins, not to mention relatively soft gold.The heavy hammer fell, the mold hit the gold ingot, and a golden Kaiyuan Tongbao was squeezed out immediately.

Gold-pressed Kaiyuan Tongbao is naturally much heavier than copper coins.

Five taels of gold ingots were cast into a two-coin Kaiyuan Tongbao, and the remaining four taels of gold, Li Wangyou didn't even look at it, and reached out to pick up the coin.

"Uncle, my nephew thinks that this gold Kaiyuan Tongbao should be enshrined in the Taimiao. Money can better represent uncle's supreme dignity and imperial power."

This time it was Mi Tuo's turn to scold his mother in his heart. Unexpectedly, this Uncle Hu County is also such a master, and he actually met his opponent!

Li Wangyou and Mi Tuo's "competition" stunned Yan Liben, who was stunned. His teacher was such a teacher... Yan Liben almost wanted to get out a small notebook to record the teacher's words and deeds, and study hard.

Yan Liben didn't think it was shameful to please a sage. The strength of character also depends on the person.

As the saying goes, it has been this principle since ancient times to learn literary and martial arts, and to be a good at the emperor's family.

Li Er was naturally quite satisfied by Li Wangyou's actions, that bright smile, and even his beard and beard couldn't help trembling.

"Haha, Ziyou is right! Mi Tuo, send these two Kaiyuan Tongbao to the Taimiao."

"promise!"

Li Er had seen this hydraulic forging machine, and was extremely satisfied, even the ping-pong-pong noise in the workshop was very satisfying.

Li Wangyou couldn't stand the noise attack, so he invited Li Er to serve tea by the river.After Li Er nodded in agreement, Li Wangyou picked up the rest of the gold ingot and threw it to the craftsman who operated the forging machine before: "Good job, this gold is rewarded to you."

The craftsman, who had been kneeling beside him with his head bowed, quickly kowtowed heavily to Li Wangyou: "Thank you for your reward."

These craftsmen are all Ding slaves of the government, and their status is extremely low.

Craftsmen with official status are "not allowed to enter other colors", which means that the occupation is hereditary and cannot be changed, and the descendants are all craftsmen.

Li Er also once said: "Businessmen of all kinds...you can only give generously to property, but you must not exceed the rank of the official, stand shoulder to shoulder with the virtuous gentleman, sit and eat together."

The humble status of businessmen and miscellaneous craftsmen can be seen from this.

Of course Li Wangyou didn't agree with Datang's craftsman system, but he had no choice but to shake his head and leave with Li Er and the others.

On the bank of the Qi River, Li Wangyou brewed a pot of tea, and everyone sat down again.

"Ziyou, it's really good to use this water power to cast copper coins. How many copper coins can you cast in a day? How much is the waste?" Li Er asked impatiently.

He couldn't help but not be in a hurry, the large amount of gold and copper coins in the Tai Chi Palace are now replaced by a mountain of private money.If he couldn't recast it into official money, he would suffer heavy losses.

"Uncle, this mint workshop is newly established. Only ten hydraulic forging machines have been made, and the daily output of copper coins is more than [-]. However, Liben is letting the craftsmen try their best to build other hydraulic forging machines. As more forging machines are completed, copper coins The output can continue to increase. As for the waste, Liben has checked and calculated, and the loss is only [-]%, mainly due to the charcoal fire and fire consumption for smelting private money."

Li Wangyou's words made Li Er rub his hands excitedly.

The loss of [-]% of the coinage is completely insignificant in his opinion.

We must know that the government casts copper coins, starting with mining copper ore and lead-tin mines to obtain raw materials, and then investing a lot of labor, charcoal fire, model casting, and the cost of raw materials and copper coin transportation, which is huge.

According to records during the Kaiyuan period, the most prosperous period of the Tang Dynasty, a money supervisor minted 22 guan coins a year, costing [-] jin of copper, [-] jin of lead, [-] jin of tin, and nearly [-]% of the fire consumption.

Calculated, for every consistent coin minted, 750 coins will be spent on the coin casting cost.
