A few months ago, Liu Bei submitted a letter to return to China. Before leaving, His Majesty gave him the "Four-Written Wuzhu Copper Module" and granted the right to mint new coins.

Liu Bei had no time to take care of him. Now, all the bandits retreated, and the Yellow Turban rebellion was rebelling again, and the traffic between the north and the south was getting increasingly severed. So he wanted to mint money and spare it.

The minting of coins in counties and countries is not the first to be created by Your Majesty.

During the Former Han Dynasty, counties and states had the right to mint coins.

In the fifth year of Yuanshou in Emperor Wu, he ordered the counties and states to cast Wuzhu coins. It was called "County and State Wuzhu", or "Yuanshou Wuzhu". Because its materials were changed to copper, it was also known as "cyanoshu coins".

However, due to the different technical levels of each country and the copper ore compositions, the Wuzhu coins they cast vary greatly. Moreover, the corners were cut, most of them were less than Wuzhu, and the more they were cast, the lighter they became, the more coarse they became. Emperor Wu then took back the rights of coins from various counties and countries in the second year of Yuanding. The imperial court minted them and issued them uniformly to prevent the flood of evil coins.

The Zhongguan Wuzhu, which was cast in the early second year of Yuanding, is mostly made of red copper and red (the copper content is more than 70% and the lead content is about 20%). It is used as the five elements and is known as "Chinji Wuzhu".

"The red coins are made of red copper as their own, and the coins are blue."

The red leap Wuzhu is made of red copper, and after fine grinding, the edge of the Guo is red. "Red leap (side)" means to file the outer wall flat, which also means the origin of the name of the Red leap (side) coins. The red leap Wuzhu is deep and round, and the grinding and filtering is exquisite, the diameter is square, and the craftsmanship is fine. The copper color is bright and pure, the color is black and lacquer, and the face of the money is free of scars and flaws.

Liu Bei used red copper to mint coins this time.

However, the price of copper ore is high. Even though Liu Bei held the right to mint coins, the amount of copper ore sold from copper officials in various places was far more valuable than the value of Wuzhu coins. The gain was not worth the loss.

Liu Bei thought of mining copper mines himself in order to reduce costs as much as possible. Only after asking, did he realize that the mining industry is now very developed.

"Now the Han family minted coins and all the iron officials all set up officials and soldiers to attack the mountains to get copper and iron. One year, the 100,000 people have already made it..."

Every year, more than 100,000 people went to "attack the mountains and get copper and iron", and the mine shafts dug were "hundreds of feet". During the reign of Emperor Wu, there were 49 iron officials in the country, and the location of salt and iron officials was an important steel smelting base. The fifty-four famous mining sites were widely distributed in thirty-one counties and countries. The types of ore mined also increased. Take copper as an example. The copper ore mined before the Han Dynasty was mainly malachite, natural copper, red copper ore and azur copper ore. In the former Han Dynasty, copper sulfide was added. In the mines, the tools for transporting ore also made significant progress, and iron wheel ore trucks similar to those used in handmade coal mines in later generations appeared.

The nearest copper mine is located in Junmi County, Youbeiping County, at the foot of Yanshan Mountain. It is about 600 miles south of Linxiang. During the former Han Dynasty, the mining industry is prosperous here. At the intersection of the Han Dynasty, the Xianbei was prosperous and the Wuhuan moved inward. It has now been abandoned. It is the natural pasture of Wuhuan on Youbeiping. Wuyan, the Wuhuan master of Youbeiping, was called Khan Lu King and was granted the title of Shanyu. He has a good family relationship with Liu Bei.

God really helped me.

Liu Bei then wrote to his elder brother-in-law and said that he wanted to send craftsmen to Yanshan to start a mine and asked Wu Yan to send troops to protect him. Wu Yan agreed readily, but that's right.

The craftsmen soon found the Qianhan Mining Area buried among the weeds at the foot of Yanshan Mountain. After careful inspection, they reported to Liu Bei and needed a little repair to re-harvest.
