After arousing everyone's curiosity, Chen Jian pointed to the lane in the distance: "Do you think this thing can make some money?"

Everyone hesitated for a while, and finally someone said, "Not necessarily. We can use a lot of cities, but we may not use that much in other cities. Ordinary civilians cannot afford it. This thing must be used with plowshares, and there must be cattle and horses."

"There are more slaves... I shouldn't buy them. This thing is expensive, and if the slave smashes it, it will be very distressing."

"Besides, there are so many fertile land near the city, and slaves can already cultivate it. But with this thing, there are not many slaves. What are the extra slaves doing? The extra slaves have to eat for free? If you leave the city and go to cultivate a distance, you will have to worry about the slaves running away."

Chen Jian clapped his hands and said, "It's well said, so I've come up with a solution. You can do it first. After the carts in our cities are popularized, you can concentrate the money you have in your hands to build some small workshops, farms, etc. You pay for money and technology, they pay for slaves that they don't need, you hire slaves and give money to the slave owners. The money given is more than each slave produces on the land every year. How will they choose?"

Everyone thought for a while and said, "Then we can only do it in places like Echeng Acropolis. Our money is only known to several cities near Caohe."

Chen Jian laughed for a while and said, "I won't know anymore."

A handful of copper coins and a gold coin cast from the cloth bag and threw it to everyone. Everyone was immediately attracted by the round currency. This thing looked very good, and what was even more magical was that each looked exactly the same.

The copper coins were molten and cast. Chen Jian asked them to carve sixteen handmade coins with tin. Using the sand turning method, they placed the tin coins in fine sand turning. Half of the thickness was in one side of sand turning, and the back was in the sand turning on the other side. After the upper and lower parts were separated, the tin coins were taken out.

There are eight rows of sixteen tin coins in a row, a total of two rows, and a wooden stick is clamped in the middle. After removing the wooden stick, the gap in the sand is like a tree. The money is a leaf, the stick mark is a tree trunk, and the gap is to pour copper juice into it. After filling the copper juice, pick the copper coins from the tree and grind it, throw the copper trunk into it and return to the furnace. The sand can be used to turn it over.

The technical conditions for melting and casting copper coins have been ripe. Now the smelting furnace can reach a high temperature of more than 1,400 degrees, and the melting point of pure copper and pure gold is only a little over 1,000 degrees. After reaching 1,400 degrees, it will melt perfectly.

The biggest requirement for melt-casting things is the fluidity of the metal solution, because there will be bubbles inside it, just like blowing your nose. There are often bubbles in the snot, and there are even sayings that it is beautiful to make the snot bubbles. But if it is a pool of water, there will definitely not be so many bubbles because they are not sticky.

The copper juice melts perfectly, and it is not a big problem for casting money. Of course, the problem for casting other things is not a big problem. For example, the shell of some objects that need to bear huge pressure periodically, the melting point of pig iron is too high, and the fluidity is not good, and there are bubbles. In fact, the inside is also an uneven frozen body of graphite, iron carbide, and iron. The bronze is like a cup of salt water, while pig iron is more like a mixture of water and oil.

If you want to promote currency, you must break the custom of bartering and rely on the development of the natural economy to break this habit. You can't think of it for two hundred years, so Chen Jian still wants to treat currency as a token and bind it to workshop supplies.

In addition to lending a batch of currency to cities that want to buy iron tools, the use of the people will be completed by these small groups not owned by the whole people or owned by individuals.

In Xiacheng, those with more land can work alone, and those with less land can join forces with more than a dozen or twenty companies. The planning and statistics department is led by the public property, and the civil forces of the other cities serve as pillars to radiate to the surrounding cities by establishing farms and low-level product workshops.

At that time, the goods of the Yucheng workshop group will only be charged copper coins, or they will be cheaper than physical goods. The workshop group in nearby cities will exchange copper coins for labor, or use copper coins to purchase raw materials.

Tao Bei is easy to imitate, and now people have accepted the simple concept of currency within cities, so Tao Bei has fulfilled his mission and it is time to step back and serve as a witness to history.

Copper coins are more formal than pottery, and their copper content gives them certain use value and are more easily accepted.

The old Chinese people who were rubbing copper coins obviously liked this thing very much, and they also guessed that this thing was a new currency. They were thinking about whether Tao Bei would be replaced with this kind of copper coins? This thing seemed much more reliable than Tao Bei.

After Chen Jian made everyone happy for a while, he waved his hand and called all the Chinese people who were still trying to get tired of trying to get a car and surrounded the ground.

"Now there are plowshares and iron trunks, and some rules are about to change. For example, your fiefdom must pay a lot of grain every year, which is based on the quota. It cannot be less. After completing these quotas, you will farm if you are willing to farm, and if you are willing to do something else, but the quota of grain is the bottom line. If you cannot complete it, you will recover the fiefdom. No matter how much money you can't eat, can you understand? We must first ensure that we can eat enough."

Everyone nodded. This is easy to understand. I haven't been hungry for a few years. There is no need to say anything more about this principle.

"Originally, you might have to work on the land to pay so much food. Now you don't need so many people anymore. It may be that the fief of 600 people only needs 200 people to farm to complete the quota. What should you do if the remaining 400 people are? Of course, farming is also OK. The question is that now there is enough food. If the grain earned by one person's farming is done, will it be more profitable?"

"For example, raising horses, raising cattle, raising sheep, logging, making wine, making wood, and making iron. Our control may be put on the place next year. You still cannot do salt, iron, copper ore, but other things may not be managed by the public property. You all think about what your fiefdom is suitable for. I thought about it and asked the people from the Planning and Statistics Department to see if your ideas can be implemented."

"Another, the grain paid by your fiefdom every year may change. If I want wheat this year, you must free up some of the land to plant the wheat I want; if I want beans next year, I will take out beans for me. You said beans are more expensive than wheat, so I want to plant beans... Don't even think about it before the quota is completed; if the quota is completed, you are willing to plant as many species. Don't blame me for not explaining clearly. If the quota is not completed by then, it will be hard to say whether the fief is yours."

For these people sitting on the land, this was a huge news, and even shocked them.

From the beginning of Xiacheng's construction, everything was controlled by the public industry, from grain to pottery to bronze. Now, this means that part of the control should be relaxed, leaving only the things that must survive will still be controlled by the public industry.

A few people thought of some ways to make money almost in a moment. They thought about it before but couldn't do it and didn't dare to do it, but now they have the intention.

He pointed to the plowshare lanes with quick heads: "So the key to the problem is these things? Only by using these things can we free up people, and each person will produce more money every year."

Chen Jian praised a few words and said, "So I asked you to come here. First, there are many things you need to learn. You can learn by yourself, or send a letter to ask a few people to learn from your fiefdom. Some things can't be learned by your eyes and you have to work with your own hands. You can know how much acre of land can produce and plan future things. You won't be unhappy to let you work here until autumn, right?"

Everyone laughed, and one person said, "What's wrong with me? I used my hand to dig the ground with a stone in my hand a few years ago, but now I'm just holding a plowshare. What's wrong with me? Sometimes I can't figure out that the child Manyuan has just been full for a few days, so I feel unhappy when I ask him to come to the farm, as if he is torture him by working."

After joking for a while, Chen Jian stood up and said, "Okay, I'll set a piece of land for you. You can use plowshare carts to cultivate yourself, and send a letter to ask the fief to learn a few people, otherwise you won't know how to use plowshare carts for you."

"I agreed that this thing cannot be given to you for nothing. The workshop in Yucheng belongs to everyone in Xiacheng. You have to spend money. I can't afford so much money, but I can give it to you first. You can give it to me in real things within a few years. Horses, wools, carts, woods, and grains are all fine."

Everyone was fine and nodded, "We can distinguish between public and private. If you don't have money, give it to us. Those who don't have a fiefdom in Xiacheng should be unhappy, and this doesn't make sense."

"Just understand. While the weather is warm, you will build a few houses for yourself. This is for yourself. You can only blame yourself for being lazy when you leak wind and rain. You will have to leave some people here in the future. If I have any new ways, I will first promote it in this farm. You must send people to watch it here, so that we can change it every two years to avoid using horse-drawn plowshares. You are still grinding stones."

The people received the tools and went to build their own hut together while chatting and laughing. A few people would come together in groups, and while working, they discussed with each other what they could do in their fiefdom.

In fact, there are many things that can be done, many things, and there is no technical bottleneck, just a little twist of your head.

Take the agriculture of the two cities in Xiacheng and Yucheng for example. There are countless things that can be done according to local conditions. This place is similar to the Central Plains in the previous life. There are no paddy fields or rice, so there is no need for buffaloes. Cows and horses will rot their hooves in paddy fields, and they will be like fish in water in dry fields.

The horse pulls the plow faster, three times faster than the cattle, but the cattle can plow deeper and requires less care from people, and each has its own strengths.

Take the cow and horse for example. There are many thinking that has no technical bottleneck but is hugely progressive.

The horse harness in my previous life took a fork in the road. At first, it was tied around my neck like a cow. However, the cattle and horse look different, and the consequences can be imagined. It was not until a long time later that the horse harness was moved from the neck to the chest and back to make the horse a useful field animal. There was no technical bottleneck, and it was completed without detours when I was in Xiacheng.

The feed of cattle and horses will make cattle and horses grow better after being stored and fermented, and there is no technical bottleneck.

The meadow near Onozawa is dug in late autumn to let the water pour in. This can not only ensure that the grass will not freeze to death because of the cold weather, but also make a large amount of silt to ensure that the grass will be more plump next year.

When the remaining soybean cakes are processed, you can feed cattle and horses as high-quality fat-licking feed; cows and horse manures are fermented and fat fields can increase crop yields; legumes and grass plants can rotate crops, which can use the nitrogen fixation effect of legumes to increase the yield of staple foods, and in turn, a large number of beans can increase the number of cattle and horses.
