So for most of the past six months, Yu Xiaotian has been spending money to buy slaves and transport them back to the island, and the young women are rewarded as a benefit to those who have no families on the island.

Boys or girls stay in some of the island's workshops to apprentice the craftsmen and let them learn various trades, while the girls mostly stay in the garment workshops to work, and if some of them are willing to go on the ship, they can also be sent to the ship as trainee sailors, so that they can learn the art of navigation.

As for the young and strong men, they were put into various workshops or boats to serve as workers.

Yu Xiaotian is not very resistant to this kind of human trafficking, although such a thing is regarded as a violation of human rights by later generations, but in this era, this kind of slave trade is a normal thing.

For these slaves who were bought with money, their status was different from that of ordinary immigrants, they had no personal freedom, and their wages were not high, and they also had their own consciousness, knowing their identity, although they were not necessarily willing, but they were also honest and resigned to their fate.

Many of the slaves were bought without knowing that they would be transported here to become slaves of the pirates, and it was not until they were loaded into ships and sent out to sea that they knew where their future was.

Some people are reluctant, but they can only accept their fate, and very few of them will resist, and can only pray to God, hoping that they will not be too miserable when they reach the den of thieves.

But after arriving at Nanri Island, they found that things were not as bad as they thought, although they had to go through the so-called quarantine for the first half month, take away their clothes and burn them, shave their hair (except for women, Yu Xiaotian was not interested in seeing nun-like women appear on the island), give them a decoction to fight insects, and scrub them from head to toe, these practices made them both puzzled and afraid.

But once the quarantine was lifted, they found that these vicious pirates were not as bad as they thought, and they even had to call them good.

After they were released from quarantine, in addition to giving them new clothes, they were also given a clean and tidy place to live, and each of them also had a set of toiletries that could be changed regularly.

In terms of eating, although it is also a big pot of rice, but the quality of the rice is beyond their expectations, three meals a day, thin in the morning and evening, dry at noon, there are porridge and vegetables, although it is mostly some sea vegetables, but it is much better than what they ate before they sold themselves, and even every three or five days, they also gave meat to eat.

When this was on land, the slaves did not dare to think about it, and the house slaves rarely ate meat, even if it was a little fishy, it was also some offal of animal offal, and the amount was very small.

However, the meat served here is a large piece of good meat, mainly fish, and occasionally whale meat, which is said to be eaten only by the rich.

They only need to work for five hours a day, get up early in the morning, work for two and a half hours at noon, and work for another two and a half hours after eating in the afternoon, and then return to their lodgings to rest by hand, and they can arrange their own time in the evening.

The sea wolf also provided them with something called playing cards, taught them to play with it, gave them some wages every month, and gave the leader a day to rest and wander around the island's shops and buy some personal supplies.

This was unimaginable for those of them who were slaves, so the slaves who came here earlier gradually stayed with peace of mind.

What's more, the sea wolves gave them an appointment, as long as they worked for the sea wolves for five years, they could leave their citizenship and become commoners, no longer slaves, and they could choose to be farmers in the future, or they could continue to work in the workshop, and if they stayed in the workshop, they could get the same remuneration as other craftsmen.

With this hope, the slaves naturally felt more motivated, so most of them were more at ease on the island and did not make any trouble.

Now Yu Xiaotian wants to build a large number of buildings in Jilong Bay, and he needs manpower, so the first batch of personnel still chose these slaves who had no freedom, selected a group from among them, plus a newly purchased batch of slaves, and shipped them to Jilong Bay.

There were also a lot of construction tools and a large amount of supplies to Jilong Bay, which could meet the needs of the personnel stationed in Jilong Bay for a month, and there were also six construction craftsmen on board, and after they arrived, they had to take these people to start building the Jilong Bay village and two forts.

Originally, Yu Xiaotian wanted to go with the boat again, but considering that the first batch of people was relatively small, it was not enough to meet the needs of building a village, and he also had a plan to clean up Chen Jiu, an old rival, and seize the territory of Funing, so he decided not to go for the time being, and ordered these people to build the fort on Heping Island first.

Yu Xiaotian also took the time to meet with a few archers and drew a sketch of the fort, and asked them to design and build the fort on Heping Island according to this sketch.

Yu Xiaotian knew that Heping Island was the gateway to Jilong Bay, and the solidity of this fort directly affected the safety of Jilong Bay, so he decided not to build it, and if it was built, this fort must be built very strong.

He didn't study architecture, but he knew the benefits of the fortress, which was a new type of fortification that gradually appeared in the West after the appearance of artillery, and was a very strong fortress that could effectively resist the invasion of artillery fire, and at the same time had a very strong defensive power.

Therefore, if it was to be built, Yu Xiaotian did not plan to build a wooden village as before, and he decided to use a hollow fortress to build the Heping Island Fort, which was the most important fortification in Jilong Bay.

He did not know how to architect, so he could only draw a rough sketch of what kind of fort he wanted to build, which was polygonal, with protruding and recessed positions, with firing holes in the walls of the fort wall, and gun emplacements built on top to mount heavy cannons.

At first, these craftsmen didn't quite understand why Yu Xiaotian wanted to build this fort into such a strange shape, and even Wang Hong and others couldn't figure out what to do with such a strange shape of the fort with so much effort.

So Yu Xiaotian took a ruler and compared these craftsmen on the sketch, and at the same time explained to Wang Hong and others.

After Xiaotian finished speaking, everyone knew the power of this fortress, the polygonal city wall, it seems not to be very thick, but from any angle, the city wall is inclined, so the thickness of the straight line of the city wall has increased a lot, and it has become very thick.

This is not nothing, the key is this strange-shaped fort, the perforations opened everywhere, it seems that they are not facing the sea, but are opened in an inclined state, and the guards in the perforation may not be able to shoot at distant targets, but if someone wants to attack this fort, they must go ashore and approach the fort.

At this time, according to Yu Xiaotian's explanation, everyone discovered the cruelty of this kind of fortress, no matter what direction the attacker attacked this fort, it just happened to enter an area covered by the crossfire of the defenders of the fort, and the attacker could not directly shoot the position of these holes with artillery, so he could only stand below and wait to be beaten.

Even if they were close to the fort, they could throw fire pots from the emplacement's perforations, burning the enemies gathered below, or even throwing stones down, which the attacking enemy could not resist.

If they wanted to climb the ladder, the guards in the fort, in addition to shooting the unsuspecting backs of the attackers from the other direction, could also poke out their forks from the half-mid-waist holes and push the ladder down.

Therefore, once this strange-shaped fort is established, if you want to capture it, it will become a nightmare for the attacking side, don't look at the number of guards of the fort, it will not exceed a hundred, if the attacking side wants to take this place, at least not invest more than ten times the troops, and don't want to take this fort at all.

Moreover, Yu Xiaotian sketched the room of the garrison, the passage of the battle, the underground ammunition depot and the grain reserve warehouse, and the passage for the movement of the guards, etc., but these are only a rough sketch, and how to arrange it depends on these craftsmen to exert their ingenuity.

So several archers understood what kind of fort Yu Xiaotian wanted to build, and nodded again and again to show that they understood, so Yu Xiaotian sent them on the ship and sent them to Jilong Bay, so that they could first build the fort on Heping Island as soon as possible, and the construction materials should be shortened as much as possible, and the building materials should be used locally, and the stones on the island should be mined as materials, leaving the time and cost of transporting other building materials.
