When Jing Wen heard about this silver coin, he might have various problems and immediately had a headache. Now, not only does the coin cost, but also what currency quality is not up to standard, and other factors will cause the silver coin proposed by Jing Wen to fail to achieve the ideal result. If the silver coin plan cannot be opened, then Jing Wen's goal of controlling the Tang Dynasty's economy by minting currency will not work. Therefore, Jing Wen is thinking about how to make this currency well and save the cost of minting and let himself live in the so-called coin tax. The coin tax is a huge benefit, and the ordinary government cannot see it at all. Now that he has the opportunity to issue coins, he naturally has to make a big profit, so that he can be worthy of his right to mint!

"If there could be something that could push out coins! But how could a person's power be able to push silver coins well?" Cui Ying said.

Cui Ying's words immediately made Jing Wen's inspiration. That is, you can use stamping to mint coins without melting silver water and then minting coins! If you use stamping, you only need to make the silver into a small ball, put it in the middle of the mold, and then press the mold hard. After pressing, the silver coins can be taken out. This can be said to be a low-cost and efficient method. Moreover, the coins cast out have a delicate appearance and clear texture, because they are pressed at one time, not the kind of artificial pouring silver water and then cast again. This method is very difficult to control the weight of the silver coins, causing too much error. But stamping doesn't matter. Stamping only needs to be cast into a small ball of the same weight at one time, so that it can be pressed at one time. This is not only convenient, but also saves costs.

"Yes! We will use this pressure manufacturing method!" Jing Wen said.

But Cui Ying said: "But we, even the strongman, cannot suppress everyone the same!"

Cui Ying didn't know what pressure was, because even if you are a person, you can't suppress all kinds of silver coins with great strength! Moreover, manpower is limited, so it is naturally impossible to suppress silver coins with force for a long time.

Jing Wen smiled but said nothing. He obviously had a solution, because manpower was not good, so he could use mechanical ones! Only mechanical ones could make the same style of silver coins.

A few days later, Jing Wen came to the bank's mint and looked at a huge iron pillar hanging in the air. Then there was a box below, which was empty and carved with various patterns. Then a man who looked strong opened the box and put a few small silver balls in it. Then he left immediately and pulled a thick rope.

"Gra——" The iron pillar was pulled up.

Of course, this iron pillar is very thick and even a strong man cannot pull it. However, this iron pillar is made of a pulley set, so he can pull it up. When the pulley set reaches a certain height, the strong man suddenly let go.

"Dong--" With a loud bang, the iron pillar fell down along the gravity of the earth, and then arrived at the alloy box made of mixed metals.

The alloy box was pressed down hard. Then the small silver ball inside was deformed and finally became a round sheet-shaped thing.

Jing Wen asked the strong man to pull up the iron pillar again and then took off the box. Jing Wen took out a piece of stuffed with a circle from the box and looked at it.

"Successful. The stamping machine successfully minted coins!" Jing Wen said excitedly.

Jing Wen started drawing the design drawings of the stamping machine he designed a few days ago, and in the past few days, he asked senior craftsmen to make various parts of the stamping machine, and then tied various machines with ropes, thus forming an original human press.

Jing Wen knew that he had completed another invention, namely a stamping machine. Of course, this stamping machine is a very primitive human press. It is not an advanced thing. If it were later, it would probably not be too practical. In the end, it would be to use manpower and then pull the iron column to a high place. Then, it would use the weight of the iron column itself to smash it down and become the result of a stamping. This is the most basic reason for the stamping machine, but later it became more and more advanced and the accuracy became higher and higher, but the principle did not change at all. This kind of stamping machine can only make things that do not require very high precision.

Jing Wen successfully used this stamping machine to mint this silver coin, using the weight of steel to stamp the silver coin mold, and as a result, the silver coin was directly pressed into silver coins. Now the silver coin can be stamped out in this way. The cost of the stamped silver coins is much lower than that of the silver coins made of melted molds, and it also saves costs. Moreover, because the stamping machine is cold and is not as high as melted silver water, the service life of this mold is higher, and it has a longer service life than those hot silver water.

"Jing Wen, can this stamping machine be used to make copper coins in the future? Many things can even be used to make them." Cui Ying asked.

"Of course, this stamper has more uses. It can not only be used to make silver coins, but also copper coins can be used to make them. Moreover, many weapons can be forged in the future, especially those blunt objects. Also, gold foil is already made, so it is much easier. There is no need for so many people to smash it with hammers. As long as the stamper is smashed down, a large pile of gold foil can be made. So, this stamper is a huge invention, and this is the world's first machine tool, and the historical significance is different!" Jing Wen said.

Jing Wen was very happy because the world's first machine tool was born like this. Although this machine tool is the press machine with the lowest technical content, that is, a stamper, the historical significance is different! The first person in anything is enough to remember it in history books and is very well-written. Although this stamper still uses manpower, it means that the processing of various parts has entered a new era. From now on, from industry to military, China will become stronger and stronger.
