Chapter 463

Li Er is so excited because what Li forgets to worry about is too incredible.

Dozens of craftsmen can make thousands of copper coins in one day. This efficiency is really amazing.

You know, the Ministry of household and the craftsmen who will be the prison for casting copper coins have nearly 10000. If more craftsmen were arranged to cast money according to this proportion, wouldn't the Tang Dynasty be able to solve the problem of money shortage?

"How much does it cost?" Li Er's voice trembled. Whether he could have enough copper money is naturally very important to Datang.

"The consumption is very low, mainly the consumption of molten copper and the salary of craftsmen," Li said with certainty.

"Seriously? Tell me exactly how you did it?"

Li forgot to worry and smiled. He first asked Li Er, "uncle, do you remember the waterwheel I built in Dingzhou village?"

"Naturally, I remember that the waterwheel is even magical. Without manpower, it can lift the water to a high place for irrigation."

"Hehe, uncle, don't you think the waterwheel has other uses?"

Li Er was puzzled and didn't understand what he meant.

Li Qieyou took out a drawing drawn in advance and presented it to Li Er: "uncle, please see, if the bamboo tube for taking water from the waterwheel is removed and replaced with a baffle, the waterwheel will still rotate under the push of the water flow."

"Yes, it is."

"So, you can use the power of water to do many things. Uncle, please look here."

Li Qieyou pointed to a device drawn on the drawing and said, "my nephew designed a hydraulic forging hammer stamping machine, which uses the water flow to drive the waterwheel to rotate. While the central axis of the waterwheel rotates, it can constantly lift and fall the forging hammer. My nephew calls it a hydraulic forging hammer."

Li Er still didn't know why. He looked at Li QIAOYOU blankly.

Li Wangyou can only make complaints about this in his mind, Nima, this technology is illiterate! There is no sense of science!

Without beating around the Bush, he directly explained: "uncle, all the copper coins in the Tang Dynasty are forged, which takes time and effort. The hydraulic forging hammer designed by my nephew can directly punch and knock copper plates into coins!"

"How is it possible to knock copper plates into coins?" Li Er still couldn't believe it.

Li forgot his worries and was speechless. It was too painful to explain science and technology with his hand on his forehead and "illiterate"!

China has been casting coins since ancient times, even in the Qing Dynasty. The West began to use stamping coinage in the Greek and Roman period.

Stamping coinage not only has clear and distinct patterns, but also because of technical advantages, it is difficult for people to copy, and has a good anti-counterfeiting function.

Of course, more importantly, the cost of stamping and coinage is much lower than that of casting coins, and the speed is fast. Coins are formed at one time without time-consuming and laborious follow-up processing.

Li forgot his worries and spent nine cattle and two tigers to compete with each other and draw pictures. Only then did Li Er finally understand the meaning of the drawing in front of him.

"Wonderful! It's really wonderful! If we forge and punch coins according to Ziyou's water conservancy, we can solve the shortage of money in the Tang Dynasty!" Li ERLE narrowed his eyes, as if he had seen the Treasury full of yellow copper money.

However, he quickly reacted and looked at Li forgetful: "Ziyou, what does it have to do with you collecting so much private money?"

Li forgot to worry and couldn't resist the impulse to roll his eyes. He could only explain patiently.

"Uncle, hehe, coins need copper."

When he said this, Li Er immediately realized it. Datang's copper coins not only need copper, but also contain other metal components. The materials used in Kaiyuan of the early Tang Dynasty were bronze, white copper and some other metals.

Although the casting technology of those private money is not as good as that of official money, the materials are very particular, which is almost the same as that of official money.

If there is a new coinage method, these private money can be remelted and minted into official money.

According to the method of stamping and coining coins, Li Qieyou can recast the 3 million jin private money he received from the Wang family in Taiyuan into an official money.

That's six hundred thousand!

Even if there are losses and costs in the coinage process, at least 500000 copper coins can be forged!

At the beginning, the copper money lost by the Wang family in Taiyuan to Li Qieyou was only 300000 yuan. This will nearly double the profit.

To understand the key, Li Er's breathing was fast.

"Ziyou, you can't joke about this! Are you sure?"

Li forgot to worry and nodded: "as long as my uncle asks the craftsman who will be the supervisor and the Ministry of work to cooperate with me, I will soon get the mint out. At that time, my uncle will know as soon as he tries. If my nephew has a little falsehood and there are three million kilograms of private money in the palace, my nephew is willing to accompany my uncle."

Naturally, he was so sure that he dared to say such a thing.

Before Li's rebirth, a friend made "counterfeit money".

In fact, it is not counterfeit money, but forged antique copper money with a stamping machine and sold as handicrafts.

So he knew how to punch coins very well. At least in this era, it definitely belongs to the "brick family" level.

Li forgot to worry about such a determined answer, but let Li Er meditate and keep pacing back and forth in the hall.

After a long time, Li Ercai reached out and called Mituo into the hall.

"Mito, I give you a task."

Mito was so frightened that he knelt down: "Your Majesty, but driven, slaves and maidservants dare not die."

"Well, it's not a terrible thing. I'm going to let you use the copper and gold in the palace to exchange them into private money."

What? Mito thought he had something wrong with his ears. Is this auditory hallucination?

Li Er asked him to exchange gold and copper money for private money?

I'm afraid it's not crazy?

Private money what's that? They are all copper coins forged by aristocratic families without permission. The workmanship is rough. When they are taken out for use, they are two or three pieces, which can be used as an official coin.

Even aristocratic families are reluctant to use these private money.

And now your majesty let himself exchange the gold and private money in the palace for private money?

"Remember, don't make a public announcement about it. Let the Baiqi company do it and exchange all the gold and copper coins in the palace into private money and bring them into the palace, okay?" Li Er ordered again.

Mito finally understood this time and confirmed that he had no auditory hallucinations. He turned to look at Li forgetful, hoping to get an explanation from him.

Li Er's request really goes against common sense.

Li forgot to worry, but he was shocked by Li Er's great pen. This goods is darker than him!

He remembered that last time Li Er wanted to go to the aristocratic family gambling house and asked Mituo. He knew that there were more than 80000 liang of gold in the palace.

All of this needs to be converted into private money, and then all of it will be melted and cast into copper money. Once it comes and goes, the profit will be astronomical.

However, Li forget worry will not stop Li Er. Anyway, almost all private money is forged by the aristocratic family. Li Er is sucking the marrow from the aristocratic family. He is naturally happy to see its success.

Even Li forgot to give Li Er some advice: "uncle, you can let Baiqi take the gold and copper money to the States and counties for exchange. My nephew heard that the more remote the States and counties are, the higher the proportion of official money for private money."

Mito was really going to cry when he said so.

He wanted to break his head, but he couldn't understand what the uncle and nephew were doing
