The current currency of the Han Empire is gold, silver and copper, of which the copper coin is also the copper coin, the copper coin is mainly cast from the alloy of copper and tin, lead and zinc, the casting of the copper coin is completely in the hands of the imperial court, the local government and the powerful are not qualified to mint copper coins, and the local minting of copper coins is a felony, except for a few people who are willing to take the risk of losing their heads to do this kind of thing, few people will do this kind of thing.

But gold ingots and silver ingots are not the same, these two precious metals, if the local government and wealthy families have enough gold and silver in their hands, they can smelt and cast gold ingots and silver ingots for storage and circulation, and the imperial court is not restricted, which has caused a lot of chaos, many black-hearted people, in order to make huge profits, they mix tin, lead and other metals in the smelted silver, shoddy, deliberately adulterated, causing a lot of chaos.

In the actual use process, the natural gold ingots and silver bullion as currency circulation also have a lot of drawbacks, very unfavorable to the development of commerce, take any merchant in Pingxi City, those merchants in the receipt of the gold seal, first of all, the boss waist has enough eyesight and eyesight, through the feel, weight, color to identify whether the gold and silver they received is adulterated, if the confirmation of the received gold and silver fineness is sufficient, the second step will be the received gold and silver on the scale to weigh it, determine the weight, the third step, if the received is silver to change, many times, the owner of the store will use steel scissors, painstakingly, cut the silver to find change, so behind those business counters, the scales that weigh silver and the steel scissors that cut silver are almost all necessary things for merchants, Yan Liqiang saw in film and television dramas in his previous life The kind of situation where everyone buys things and eats casually and throws away a piece of silver, although it can't be said that there is no, but it is far from the reality and the lives of many ordinary people......

If the silver is not in good condition, when the shopkeepers and bosses see it, they either do not accept it, and even if they receive it, they will have to discount the price, which will cause many disputes, and at the same time, because of the accuracy of the scale of the silver, for the weight of one or two grams of silver, the situation of merchants and customers arguing and fighting is also everywhere.

The imperial court was powerless to deal with these situations, so it could only let them go.

There are also a small number of scarce silver coins and gold coins in circulation, but those gold and silver coins in circulation, in fact, are not gold and silver coins in the real sense, they are just some wealthy families in the smelting of the gold and silver deliberately made the gold and silver of the big ingots into a similar copper coin, such gold and silver coins are made very rough, the standard weight is not uniform, the second is that the number is also very small, there is no large-scale circulation, those gold and silver coins, most of them are engraved with what longevity words and what is the joy of Tian Ding and the like, those things are a small number of wealthy families in order to show off, in some important family celebrations to get out and give to the next person, so these gold and silver coins are essentially small pieces of precious metal that have been divided......

Those wealthy families of the Han Empire did not understand the meaning of minting gold and silver coins, but for Yan Liqiang, turning the circulating gold and silver into circulating gold and silver coins contained a great opportunity - the right to mint coins!

Once the gold and silver coins issued by the Qiyun Governor's Mansion circulated in the market and became the circulating currency that everyone was willing to accept, creating a fait accompli, once this credit was established, it would be impossible in the future.

It is a pity that no one in the Han Empire has yet been able to see the significance of this, perhaps some people have thought of casting gold and silver coins to facilitate circulation, but there is no technical means to achieve it, because it is not an easy thing for those people to cast gold and silver into currency, and it is too expensive to make gold and silver coins according to the current technical means, which is too great and unacceptable.

For Yan Liqiang, all this is not a problem at all, because to mint gold and silver coins, only one minting machine is needed, and the most reliable and stable minting machine - The structure of the elbow press coinage machine is not complicated for Yan Liqiang at all, he has ready-made drawings in his head, the structure of this machine is even simpler than the steam engine, there is no complicated structure and parts, and it is very durable, and the efficiency of coinage is also high, the coinage machine he saw in the museum in his previous life, some of them can be used for nearly a hundred years and can continue to be used.

Yan Liqiang has even thought about the appearance of gold and silver coins to be issued, all gold and silver coins, originally based on one penny as the basic weight, one or two silver coins is ten silver coins, and one or two gold coins are ten gold coins, which is easy to calculate and easy to use......

It was only a few days before he gave the drawings to the manufacturing bureau, and the craftsmen of the manufacturing bureau are estimated to be still exploring and studying the mystery of the elbow-operated press mint in the past few days, and they have not yet understood it thoroughly, but Yan Liqiang believes that in a few days, the manufacturing bureau will be able to put the first mint in front of him.

......

As the sun set, the four-wheeled carriage in which Yan Liqiang was riding finally stopped.

The car door opened, Qian Su and Lu Wenbin got out of the car first, and then Yan Liqiang tidied up his clothes and then got out of the carriage.

Outside the carriage, it is already in front of the gate of the county government of Yingwei County, the accompanying guards stand on both sides of the county office, surrounding the street, many people in the county are probing their brains around, wearing a county official uniform, wearing a black gauze hat on his head, Fu Changde took a cadre of officials from Yingwei County, standing at the gate of the county government in a proper manner, seeing Yan Liqiang coming down, Fu Changde took all the officials and officials in Yingwei County to the ground, "Changlu, the county commander of Yingwei County, has seen the superintendent......

In order not to let people guess his origin, and in order to let the Shatu Seven Department relax their hostility towards the newly established Qiyun Governor's Mansion, Fu Changde has been using a pseudonym instead of his real name until now, except for Yan Liqiang, even the people around Yan Liqiang don't know his true life.

Yan Liqiang glanced at Fu Changde, then looked at many familiar faces among the officials in Yingwei County, and smiled, "Lord Chang, are you still used to wearing this official uniform?"

"Today, I know that the Governor is coming, so I put on this official uniform to greet me, so as not to be rude, on weekdays, I feel that this official uniform is a little cumbersome, and I feel that there is no sheepskin jacket to wear...... "Fu Changde grinned and smiled at Yan Liqiang, that smile, with a bit of cunning and hidden sharpness, is impressive, among the people Yan Liqiang knows, only Fu Changde can have such a smile on his face.

"Okay, you don't like to wear this official uniform, I will allow you not to wear it when you see me in the future, and it is not your crime of being rude!"

"Thank you, Lord Protector!"

Yanqiang raised his head and looked at the somewhat mottled county gate in Yingwei County, Yan Liqiang touched his stomach, "Okay, let's go inside and talk, Lord Qian and Lord Lu and I have been running on the road for a day, and our stomachs are already hungry, so let......'s have dinner first."

"Dinner is ready, a few adults, please!" Chang Lu said, bowed over, and walked into the county office with Yan Liqiang, Qian Su and others.

Chang Lu also knew Yan Liqiang's temper, and knew that Yan Liqiang didn't like to talk about pomp and circumstance on such occasions, so the dinner prepared to welcome Yan Liqiang was only sumptuous, with meat and vegetables, and it was made exquisitely, which was not a luxury.

After dinner, Yan Liqiang had just rested for a while in the official office where he was staying behind the county office, and Fu Changde and Situ Feixing, who was wearing an ordinary errand uniform, walked into Yan Liqiang's room together......

After letting the two sit down, Yan Liqiang asked Situ Feixing directly straight to the point, "How is the connection with the Black Monsters?"

Situ Feixing licked his lips and glanced at Yan Liqiang with some admiration, "The young master is like a god, the black people have already taken the bait, and after tasting a little sweetness, the appetite of those black people is getting bigger and bigger......"
