While sulun was busy opening up a new channel, the development of Zhenbei city did not stop. Several towns were built successively from the distance from Zhenbei city to deepwater port.

The area of these towns is small, and the number of people is only about 1000. All towns are located along the Hongsha river. The original purpose of these towns is to serve as supply stations for incoming and outgoing ships. Seeing that these strongholds are developing well, the ruling office directly divided the immigrants who came in recent months into these strongholds along the river.

Since the construction of the deep-water City, the material supply here has not been interrupted. It can be said that the channel of Hongsha river has become extremely prosperous. More than a dozen ships go in and out every day, and these towns along the way are developing very rapidly.

Deep water city also sent a fleet to the southern waters. This time, their purpose is to the southern waters. The wealth of the southern countries is famous among the surrounding countries. Every year, there are caravans and fleets from all over the world for trade. The nobles of these countries can be said to make a lot of money.

The aristocrats in these countries are more extravagant than the aristocratic life in Florence, such as white sugar, honey, high-grade wine, perfume and paper, which are totally in short supply. All kinds of luxury goods produced in Zhenbei city can be sold at high prices here.

From the very beginning, the goods traded in marine trade were luxury goods. The risk of marine trade was much higher than that of caravans on the road. As long as there were endless pirates, powerful sea monsters and those terrible storms, they would suffer heavy losses. If the value of the transported goods was low, even the wages of sailors could not be paid.

The southern sea area is also the most prosperous area of the slave trade. Different from the north of the mainland, the southern region is fully developed, and the land has also been largely developed. For example, large tracts of wasteland between cities in the North rarely appear in the south.

The mild climate, abundant rainy season and fertile land make the grain output of the South far higher than that of the north. Sufficient food feeds a large number of people. Although the nobles here are more greedy by the nobles in the north, the population of the South still far exceeds that of the northern countries.

Like spice port, the largest port of Tudor Kingdom, the permanent population here exceeds 400000, and the capital population of Tudor Kingdom has reached an amazing 500000, plus the floating population, the number has even reached 800000.

A large number of people are trading here. Sulun plans to immigrate directly from here, transport a large number of goods from the north city of the town to the South Sea, and then buy slaves from here to the deep water city, which is much faster than immigrating from the kingdom of Florence.

One ship can easily transport hundreds of immigrants. One trip can transport at least 3000 immigrants. Compared with the immigrants of Florence, it took much less money and time.

The number of merchant ships in deepwater city continues to expand. With the increasing scale of the fleet, the number of immigrants will also increase. Zhenbei city will develop rapidly again soon.

At present, the first problem restricting the rapid development of Beifeng principality is the scarcity of population. The total population of the whole Beifeng principality is only more than 300000, which can't even compare with the population of a city. The northern population of the kingdom of Florence was originally insufficient, and the cost of immigration from the South was too high. Now using the fleet for immigration will undoubtedly greatly reduce the cost and increase the number of people.

The waterway development of deepwater city is very smooth. Various commodities from Zhenbei city are also sought after here, and the immigration work of Zhenbei city has also become very smooth. The arrival of a large population also makes the deep-water port more prosperous.

In the laboratory, with an aura flashing, Hathaway flashed a happy look in her eyes, and then excitedly picked up the freshly baked star robe on the alchemy platform. This is a wizard robe she specially made for herself. The main material is white dragon skin. At the same time, it is also a legendary wizard robe. After sulun had an artifact, Hathaway couldn't help but take out the Dragon skin to make a legendary wizard robe.

As a legendary wizard, Hathaway's equipment can be said to be rudimentary. Before, it was because of the lack of materials. She always used the fourth-order extraordinary wizard robe and staff. Last time, sulun brought back a large number of dragon skins in the legendary stage, and finally had enough materials.

Hathaway directly changed the wizard robe. The appearance of the starry sky robe looks very beautiful. The wizard robe is blue and white, and there are silver white decorative patterns on it. The spiritual light on the patterns flickers like starlight, which is very beautiful. It's dignified and magnificent to wear. Because it's made of dragon skin, the defense of this wizard robe itself is also very high. It can be said that with this wizard robe, Hathaway's strength has been improved by at least three layers.

With a teleportation aura emerging, Alex's figure appeared on the astrological platform. As soon as the teleportation array appeared, Alex saw Hathaway and was attracted by the wizard's robe on her.

"Sister Hathaway, have you finished making?" Alex was surprised to see the wizard robe on Hathaway.

"It's done. I just tested it, which has exceeded our previous estimate," said Hathaway excitedly.

"Really, my wizard robe is also made according to this template!" Alex decided directly.

"There are diagrams in the library. You can replace the spells on them by yourself. Su Lun brought back a lot of materials and can make several star robes," Hathaway waved her hand.

"Then you're welcome!" Alex said excitedly.

"By the way, how's your research?" asked Hathaway suddenly.

"It's much worse. The information Suellen brought back last time is very sufficient. I've verified it and there's no problem at all," Alex said.

"Look!"

Alex waved gently, and a silver metal ring appeared in her hand. The metal ring was very small, only slightly larger than the palm of her hand. It was engraved with countless arcane runes. The material of the whole metal ring was silver white, and a strong force flowed on it.

"It looks good!" Hathaway nodded.

"This floating ring has only undergone simple tests, and further tests need a lot of data for analysis."

The floating ring made by Alex is not for the wizard tower, but for the floating city. Of course, the floating ring is just a model.

The floating ring of the floating city needs more powerful power, and these power products need to be distributed to all positions of the floating city. So that the floating city will not be broken by its own gravity.

"Test it first!"

Alex nodded, then Hathaway and Alex surrendered their eyes and stood next to several steel statues. Hathaway gently waved her arm, and then several steel demons flew up directly. The coverage of this floating ring is very large, ten times that of the previous floating ring. All the steel demons in this area float at the same height.

After some transformation, the floating ring evenly distributes the buoyancy around and is specially made for the floating city. In the future, more than one group of floating rings will be installed in the floating city. In order to prevent the failure of one group of floating rings, at least three to four groups of floating rings will be installed in a floating city. Once the running floating rings have problems, stop working, A spare float ring will restart immediately. Prevent floating city from falling from high altitude.

Two legendary wizards started to test the floating ring together. With the continuous injection of magic, the floating ring flickered with a faint aura. Several steel magic statues moved around, up and down, and shifted left and right under their control.

The two soon became comfortable with the operation of the floating ring and recorded while operating the floating ring.

"The experiment was successful!"

"Sort out and archive the data on this part of the floating ring."

With the end of the test, Hathaway's aura flashed, the floating ring closed slowly, and several steel demons also landed slowly from mid air.

"According to this ratio, a floating city weighing tens of thousands or even hundreds of thousands of tons needs a floating ring hundreds of times larger," Alex said slowly.

"According to this ratio, the materials we need are not enough!"

The manufacturing process of the floating ring is very difficult, and the materials needed are also very precious. After all, it has to support the city of hundreds of thousands of tons, and there can be no mistakes and omissions,

Some of the metals used in the floating ring are secret silver. In addition, many alloys need to be used. This alloy is a special metal developed during the arcane empire. Its main function is to make the floating city.

The two cores of the floating city, the energy system and the floating ring system, are very important. Only sufficient energy can maintain the floating ring. After solving the problem of the floating ring, the next is the element fusion furnace.

The theory of element fusion furnace has long been perfect, and even element fission furnace has been officially applied, but it is not a simple thing to really make element fusion furnace.

In fact, in the period of the arcane Empire, the element fusion furnace has been widely used. Compared with the strong radiation and pollution of the element fission furnace, the element fusion has almost no radiation, and the energy output power is hundreds or even thousands of times higher.

The element fission furnace can also be used as the energy core of the floating city, but it needs to form an energy matrix of the element fission furnace and rely on several element fission furnaces to supply enough energy, but the element fuel consumed by this method will be several times higher and the endurance capacity will be greatly reduced.

"Sister Hathaway, how's the research on the element fusion furnace?" Alex asked, putting away the floating ring.

Hathaway shook her head. "There are still some problems. The energy produced by the element fusion furnace is too large for the general materials, but I have some ideas."
