In order to develop the land of Samhan and to conquer Wajima, Gongsun Kang ordered the construction of castles in Mahan and Benhan.

Along the winding coastline of the Yellow Sea, Gongsun Kang chose four locations to build near the sea, in Seoul in later generations, Taean in Chungcheongnam, Gwangju, and Jeju Island. From Hyunsu County to Jeju Island, a supply city was built by sea route.

Because the Samhan people had backward weapons and had no siege weapons at all, Gongsun Kang didn't want to waste manpower and material resources to build the city too strongly.

He chose to build an adobe city.

The construction method is like an adobe house in the countryside, only on a larger scale.

The walls were built like this. First erect two rows of wooden fences with a height of 2 zhang (about 4 meters 6 meters in modern times), and the distance between the two rows of wooden fences is 2 meters wide. Then fill the middle of the wooden fence with earth and straw, stir it with large wood, and use your feet to be sure. Layer by layer. The result is an earthen wall about 5 meters high.

Because of the simple structure, Gongsun Kang pulled 10,000 laborers and 5,000 troops to pass by water, and began to build the city a few miles away from the sea. Basically, a square earthen wall 20 miles long and 10 miles wide can be completed in a month. Yes, it's square, and this time there is no complicated diamond shape.

Towers, towers, gates, archery holes, and other buildings and functions that should be used in the city wall are all available. There are no omissions.

Whenever an empty quadrangular wall is built, 1,000 men are left to defend it. Then rush to the next location with the construction army.

Because the soldiers are very fast, and each location sends troops to touch it in advance, and all the aborigines of the sea are captured and used as labor. So until the city was built, no news came out.

By the fourth month, the army had completed the construction of Jeju Fortress on Jeju Island.

Gongson Kang decided to vigorously develop Jeju Island, which is evergreen all year round, with beautiful scenery and mild and comfortable weather. It is a typical volcanic island and a beautiful holiday destination.

Jeju Island, known as the gift of nature, is the southernmost island of Samhan, located in the southwest of the Samhan Peninsula, and is the largest island in Samhan, with an area of about 1,800 square kilometers and a population of 100,000 people.

Jeju's specialties include citrus and Jeju perfumes. Of course, perfumes are not produced yet, but Jeju Island has various raw materials for the production of perfumes. Specialties such as steamed sea bream, grilled sea bream, anchovy porridge and pheasant can be eaten.

Jeju Island is characterized by three more (many stones, many winds, and many women)

The "female majority" is due to the fact that Jeju men go fishing and have a high proportion of deaths, so there are more women than men in terms of numbers. But the main reason is that life is difficult, and women also have to work with men, so it makes women look more numerous.

Gongsun Kang left Zheng He, 2,000 soldiers and 10,000 slaves, and let Zheng He preside over the development and construction of Jeju Island. Because there are many women in Jeju Island, Gongsun Kang generously gave 2,000 soldiers and assigned 1 Samhan woman to each of them. The rest of the women and men, of course, were taken as captives and slaves, and they were left behind to build Jeju Island.

Of course, Gongsun Kang did not start to build a hedonic base until now, he asked Zheng He to build a military base. In the future, when you conquer Wajima, you will start from here. Jeju Island is an important springboard for the conquest of Wado.

After Gongsun Kang returned to Lelang County, he sent 3,000 soldiers, 10,000 displaced people, and some shipbuilders to each of the three cities of Seoul, Taean, and Gwangju (the name given by Gongsun Kang).

They were required to work mainly for shipbuilding, followed by logging, farming, fishing, and self-sufficiency.

Samhan people live on the basis of boundless forests. Along the coast, start logging. The first is to build houses, then to build boats and fish in shallow waters. The main trunks of the big trees are piled up in the shade, and they are kept to build big ships. Finally, the construction of deep-water docks and docks requires large ships that can stay more than 1,000 stones.

The open land created by logging, the roots of the trees are dug up, and the fields are cultivated for farming. One ring after another, steadily advancing inland.

In this process, the soldiers also worked together, they were recruited from the homeless people, they had not experienced the battlefield, and they could only be regarded as Tuntian soldiers at present.

In Liaodong County, there are more and more displaced people, and there are enough people. Gongsun Kang also ordered the construction of the city.

It was built in the later Dalian, Liaoning Province. The city wall Gongsun Kang asked to be built in the shape of a diamond. That is to say, the walls are not just four, but have dozens of sides. Each wall is spaced 100 to 200 meters apart. Climbing a ladder from any wall will result in a shot shot by a soldier from inside another nearby wall.

This is the inspiration that Gongsun Kang got from the European Lingbao, which is equivalent to the horse-faced wall of the Central Plains.

At that time, two large bed crossbows were placed on each wall. Build Dalian City into an impregnable wall.

Liu Yi was responsible for the construction of Dalian City. Gongsun Kang had already summoned craftsmen to draw the drawings, and after handing them to Liu Yi, he asked him to build them within two years. The city of Dalian is not in a hurry, because it is estimated that no one will attack it for several years.

At this time, the news of the failure of the 18th Route princes to jointly fight against Dong came, and Gongsun Kang was not in a hurry. He knew that before Dong Zhuo's death in the 3rd year of Chuping (192), no one would pay attention to Liaodong.

Moreover, in the 2nd year of the early peace of next year (191), the princes led by Sun Jian will discuss Dong for the second time. In those battles, Dong Zhuo was defeated, and the idea of moving the capital arose.

In the past six months, everyone has been very busy.

You Junda and Wang Bodang continued to attack, coercing the people, and turning more and more civilians into Yellow Turban Army or outcasts.

Zhang Liaoyangyi planted cotton in a large area in Donglai County, and it is expected that many people in Liaodong will be able to wear cotton clothes this winter. On the other hand, Zhang Liao recruited a large number of displaced people and sent them to Liaodong.

Tai Shi Ci is the busiest, 1, is to arrange boats to transport displaced people every day. The second is to settle displaced people on the six large islands of the Miaodao archipelago to reclaim land and dry coarse salt.

3. The goods of Liaodong and the grain and grass of the Zhen family are received and transported. 4. Establish town centers on 6 islands. Gongsun Kang later thought about it and decided that it was not necessary to build a city wall on the island. So only the creation of town centers is required.

Zhao Yun was not idle, he did not participate in the plundering of Goguryeo. However, the increasingly frequent and large-scale plundering of Goguryeo's resources and population by the army of Xuansu County caused large-scale retaliation by the Goguryeo army. In half a year, there were several acts of aggression against Xuansu County. On the largest scale, dozens of Goguryeo tribes united and sent 50,000 troops.

Zhao Yun took 30,000 newly recruited soldiers who had been recruited for less than half a year, relying on the city wall, to repel the attacks of the Goguryeo army. not only achieved victory, but also trained an iron army for Liaodong.

It should be particularly pointed out that the 800 soldiers of the Han Eight Banners left by Gongsun Kang fought particularly bravely, fought bravely, and fought bravely to be the first, and killed the Goguryeo soldiers without mercy. It can be seen how successful brainwashing is. They have come to regard themselves as great and invincible Han people.

At present, Han Baqi has expanded to 3,000 people, and there is a trend of continued expansion.

As for Xi Zhicai and Guo Jia, Guo Jia is better, as Zhao Yun's staff officer, Zhao Yun obeys his words and satisfies the self-esteem of a military advisor.

And Xi Zhicai followed Gongsun Kang, because there was no battle, he was sent by Gongsun Kang to help Xu Miao develop the mineral deposits of Lelang County in the past six months. Although it is overkill, Xi Zhicai does not care, he knows that the coming day is long, and when he attacks the Central Plains, it is the day when he can show his talents.

Gongsun Kang gave him chemotherapy once a month. With Xu Miao, the three of them ate and drank and became friends.
