"The first value of a slave is always his talent."

"For example, people who can make suggestions. These slaves do well and can often become regular workers."

Cao Wushuang frowned and said, "Become a full-time employee?"

Yang Gan smiled and said, "It means becoming a retainer."

"Also, for example, if some male slaves are skilled in carpentry, cooking, etc., then the price will naturally be high."

"If a female slave has skills such as serving people, growing vegetation, and making wine, the price will be very high."

"The second is ordinary people with no talents, so naturally male slaves are more valuable. After all, they can work."

"Female slaves will be relatively cheap, unless they are very good-looking, then the price will be higher."

"The cheapest slaves are the elderly and children. One cannot work, the other cannot work, and they have to be fed. Naturally, the price is the lowest. For no special reason, it is generally difficult to sell them."

Cao Wushuang nodded, but he didn't expect that there was such a saying in the market.

"How much can 1,500 prairie people be sold for?"

Yang Gan raised his eyebrows and shrugged, "Slaves from the Xiongnu, Jie, and Yue clans cannot be sold for money."

Cao Wushuang was surprised and asked, "Why is this?"

Yang Gan explained, "Prairie people are relatively expensive based on their skills. Most of my slaves are soldiers, young and middle-aged people, and the most important thing is."

"They all raise horses, cattle and sheep, so the prices are naturally not low, and even four or five items per unit are normal."

"It's a pity that the prairie people are wild and untamable. Who dares to buy them? What if they get violent and kill people?"

"And we have laws in Yuntong. Defeated slaves are not allowed to trade, for fear of slave rebellion. However, some Xiongnu women will be assigned to the Guizhou leader in Zhuangzi as wives after being educated."

Cao Wushuang smiled and said, "Speaking of this, I remembered that a prince in Shang State bought a slave before, and later the slave became a high official. How much do you think the slave was bought for?"

"It shouldn't be very expensive?"

"Five sheepskins."

Yang Gan smiled and said, "I'm making a lot of money now."

After the two chatted for a while, Yang Gan began to ask Xiao Yu to count all his money, slaves and money, including one penny and one bucket of grain.

Meetings are necessary. Such a huge project must be carefully planned.

Once you decide, you naturally need to calculate your assets before investing.

The same goes for slaves. Some are building canals, some are building roads, some are building docks, and there are also many slaves who are reclaiming wasteland.

But there are still many slaves digging for minerals. You must know that there are hundreds of thousands of slaves. In order to save food expenses, Yang Gan also lets them fish.

After all, after catching fish, it doesn’t take much effort and you can eat less.

But once you engage in heavy physical work, your food consumption will skyrocket instantly.

I want the horse not to eat grass, but I also want the horse to run fast. Just think about it, but it will never happen in reality.

In a large camp, dozens of masters began to get busy.

The master who knew water conservancy wrote down on a piece of paper what the specific money spent on the entire water conservancy project was.

For example, materials, wood, stone, and even copper and iron are needed in some places.

For example, in order to raise the water level, a dam needs to be built, and money is spent on such places.

Next is the relief of accounting costs, at which time the Mohist family needs to take action.

Some of the mechanical techniques they do have a very sensitive sense of the prices of materials in the world.

If you buy a piece of wood, for example, it costs 1,000 yuan. If you buy it in such a large area, you can negotiate with the county magistrate's office and it may only cost 500 yuan per piece.

Of course, there is no need to negotiate, Yang Gan himself is the county governor.

There were also food rations for slaves and fodder for cattle and horses.

All this money is money. Just move it and you will get a lot of money.

The children of the Mohist family who can stay in Xinhuo Academy are more or less enthusiastic about Yang Qian's ideas.

Their role is not only to calculate costs, but also to build machinery to assist in the construction of the canal.

The construction time of a treasure ship-class fortune ship often takes 4 to 5 years, which is recorded in the classics of the Ming Dynasty.

If a piece of wood is slightly chipped, it will be useless.

When the table saw appeared, its speed doubled exponentially, and with the addition of a crane, it was easy to finish a job that had taken ten or twenty days in the past in half a day.

That's why we were able to produce five Fuzhou ships in less than a year.

The calculation is time-consuming and labor-intensive, and it is difficult to come up with it all at once. You have to communicate with Shuihu and Shi Huacai to check.ъìＱυＧΕtＶ.℃ǒΜ

After the calculation is made, it needs to be proofread several times.

As for Yang Gan's property and grain and grass, they have been calculated, and they are about the same, so there is no big problem.

After all, it doesn't matter how much the slave eats, as long as he can eat it, he doesn't have to care about the taste.

Eating meat? It doesn’t exist. Unless there is no market for offal, I will get some.

However, the business of braised and cooked food in the county is now good, and it is enough to digest the entire county's animal offal in a short period of time.

Xiao Yu said while holding the notebook.

"Sir, our main sources of slaves are soldiers from the three tribes, people from the Shan Yu Royal Court, and nobles from the Jie and Yue clans."

Total: 865,000 people.

Mining of various mineral veins: 290,500 people.

Canal construction: 60,000 people.

Build straight, two tracks: 250,000 people.

Build docks and build warships: 50,000 people.

Build the road connecting Yuntong County to Wanghai County: 50,000 people.

Xiao Yu let out a long sigh, "Master, we only have 164,500 slaves at our disposal."

Yang Gan frowned. There were only a hundred thousand people. What a waste. Not to mention digging canals and digging latrines was too few.

"Trouble."

Seeing Yang Gan's headache, Xiao Yu pursed his lips and said carefully, "Among these 160,000 people, there are also women and children."

"Aren't there any old people?" Yang Qian asked in surprise.

Xiao Yu looked strange and said, "According to Shi Yuanji's report, old people generally like to fish in the mines, so among the 160,000 slaves, there are almost no old people."

"Oh, even a 160,000-year-old man is useless." Yang Qian scratched his head with a headache.

Xiao Yu suggested, "We have also rescued many slaves from our country, as well as soldiers from Shang and Liao. Let's see if these people can be used."

Xiao Yu made the final calculation, starting from the attack on the Xiongnu, and rescued the slaves of Xia, Shang and Liao.

There are also some criminals purchased from the two countries, as well as slaves purchased from the human market.

There are tens of thousands of people in various places.

Yang Gan flatly refused.

"That won't work. We Central Plains people have always been good at farming. Wouldn't it be nice to keep the land for farming? And there are only tens of thousands of people, which is not enough to fill the gap between our teeth."

Yang Gan tapped the table with his fingers and looked at the west corner of the map involuntarily from the corner of his eyes.

"Goguryeo, hum."

A few days flew by in the blink of an eye.

Under Zhang Yumeng's persuasion, Yang Qian finally relaxed his mind and did things he liked, such as archery, running and stretching.

If you have something, you have it, and if you don’t have it, you don’t have it. Even if you have a way to have it, it still takes time.

Don't look at Yang Qian who looks like he's convinced of Goguryeo. No one has ever touched it, so no one knows what the outcome will be.

The family can have 700,000 registered households. The specific population is also calculated according to the calculation formula of Xia State, and the specific army is calculated in the same way.

Exactly what the details are, still requires the hard work of the secret workers, and the Tianshou Division also has specialized logistics personnel.

The pieces of information about the dark men need to be compiled into a book.

"Swish swish~~~!"

The feathered arrows turned into afterimages under the power of the bow and arrow, and were accurately nailed to a big tree.

I saw that the big tree, as thick as a strong man's waist, had been riddled with holes, probably because the power of the bow and arrow was relatively average.

It's just riddled with holes, not shot in half.

Yang Gan showed a bright expression.

"Hey, the hexagonal warrior is finally taking shape."

Cao Wushuang crossed his arms, shook his head and sighed.
