The second batch of development teams sent to the seaside port are ready to set off. Su Lun specially recalled the boulder from Hongfeng city and asked him to lead the development team to the east coast.

Last night, Su Lun gave Hathaway a hard education and asked her to beg for mercy under her lightning gun.

When Su Lun woke up the next day, there was a noise outside. He carefully took away several warm fragrant nephrites on his side. Su Lun simply washed and walked out.

When he came outside, Su Lun saw the boulder coming back. He came back with the caravan in the north of the town. He sent a batch of shipbuilders recruited in the kingdom of Florence.

Boulder brought back a lot of people this time. The construction of Hongfeng city is still going on, and there is not much manpower to be transferred. On the contrary, the caravan brought back a lot of slaves from the kingdom of Florence. These slaves are locked in groups of ten people. They are thin and have a lot of black skin. They look shorter than the people in the north of the town.

"Where did these slaves buy them? It doesn't look like northerners?" Suellen said, looking at the people in front of him.

The steward of the caravan leaned over slightly and said, "Your Majesty, we received your message and needed to recruit shipbuilders, so we went to look for them immediately. With your blessing, we found these slaves in the slave market. They were slave shippers sold by a commercial firm in the southern coastal countries, and we bought them all!"

"These slave boatmans were originally owned by an aristocrat, but the aristocrat went bankrupt because of poor management and could only pay off these debts."

Su Lun nodded slightly and said, "how many boatmans are there?"

The caravan steward thought a little and then said, "there are 117 boatmans. In addition to these people, there are about 600 ordinary slaves, all of whom are strong labor. In addition, there are 30 boxes of tea and 30 boxes of porcelain, which have been put in the warehouse in the city."

"Well done." Su Lun nodded with satisfaction.

Such a caravan can bring an income of about 30000 jinnars to Zhenbei city every time. Now, the caravan in Zhenbei city has expanded to more than a dozen, trading to the southern countries, desert kingdom and lorenza kingdom.

"Boulder, give these slaves to you and send them all to deep water city." Su Lun said directly.

"Yes, your majesty!" the boulder bowed.

Sulun named the port under construction in the East as deep water city. The sea water at the port is eight meters, which is a good port. After these people are sent over, the construction of deepwater city will accelerate. After dealing with things, he went back to his study and did it.

Taking out a map of the southern port city from the bookshelf and the topographic map around Shenshui City, Su Lun began to compare it. This kind of port city sulun is also the first time to see, so when designing the deep-water City, we need to gain some experience from those port cities in the south.

As a powerful professional, he can easily control the muscles on his arm. When drawing the design drawing, even without using any tools, the straight line drawn is almost the same as using tools. Ten minutes later, a drawing was completed.

Sulun designed the drawings according to the layout of the southern port city and combined with the topographic characteristics of the east coast, which painted the simple structure of the whole city and the main layout, including roads, residences, trade areas, warehouses, city walls, towers, military barracks, etc.

There are also the most important ports and shipyards. The most important thing in port cities is trade, and port terminals and warehouses are the top priority. A large number of warehouses need to be built near the wharf to facilitate the storage of goods. The port must be large and pay attention to wind and waves. In fact, sulun is considering whether to build a breakwater.

Some things in this world are stronger than those in previous lives, such as transforming nature and moving mountains to reclaim the sea. It is not too difficult for a wizard. Even if the hydrological conditions here are bad, he can create a deep-water harbor.

Deep water city is located in the southeast coast with plenty of rain. The roads and sewers in the city need to be specially marked, especially the sewers. If it is easy to cause ponding according to the standards of Zhenbei City, attention should also be paid to the distribution of toilets and sanitation.

The problem of drainage ditches is very simple. As long as the layout is reasonable and the excavation is deeper, it is mainly due to the hardening of roads. There is plenty of rain in port cities, which often rains. If the roads are not hardened, the result is muddy, which has a great impact on the transportation of goods. Therefore, the roads in deepwater city need stone slabs or the magic of turning mud into stone.

Port cities have a large flow of people because of trade problems. Caravans from all over the world will come here to trade, which is a great pressure on the city's health. At the same time, there is also a willingness to be infectious diseases.

Infectious diseases in this world are frequent, such as plague, cholera, plague and so on. Once these infectious diseases break out, they will spread rapidly. The soldiers in the town of North Town are good, strong and strong, and strong immunity, but ordinary people can not. If outbreak of infectious diseases, it will be a disaster.

Although there are wizards in this world, wizards have no way to treat a large-scale plague and can only be isolated. Su Lun clearly remembered that a plague that broke out in the southern kingdom of Genoa in the decades before, spread to the mainland of the western port of Genoa and spread to the kingdom of Campbell in a mere two months, swept across the greater part of the continent in just a few months.

It is said that some small cities have directly become ghost towns.

After designing the road, sulun began to design other areas in the city. In addition to the urban road, it is also necessary to design a road directly to the port. This road should be parallel with at least eight carriages to facilitate the transportation of goods. At the same time, the port area needs to level the land and design warehouses and berths for ships.

Port, cargo warehouse and ship berth sulun are designed according to the southern port city. After all, people have been a port city for hundreds of years, and the design of port and berth has been very perfect.

After completing the design, I began to consider the Wizards sent to deepwater city this time. Deepwater City, a commercial city, would not be safe without wizards. Su Lun plans to let Andre go to the town and send some wizard apprentices. Andre is the blood of a water demon, and his combat effectiveness in the sea will also be strengthened.

Of course, Su Lun also needs to arrange a laboratory for him. Don't think about the wizard tower, or you can build him a small wizard tower, about 30 meters high, without tower spirit, which is equivalent to a high-level laboratory.
