Further into the study area, we will arrive at the last major functional area of the floating city, the central control area.

The central control area, as the name suggests, is for the control personnel of the floating city, such a complex city, even with the assistance of Taling, it is unlikely that Xia Duo will be controlled by one person, and secondary authority must be issued to the corresponding staff.

As a sphere, unless the height of the floor is deliberately increased, the space will always be smaller the further inside, and this central control area is like this, if you look at it from a farther perspective, it is like a "melon peel" that only fits in the main energy center.

It seems insignificant in the entire floating city, but in reality, it is the brain of the floating city.

Of course, it is precisely because of the various systems related to the floating city that Xia Duo did not actually make realistic renderings, and only replaced it with a scene similar to a rocket launch command center.

But obviously, after coming to the site in person, Niya easily found that the scene shown in the renderings did not match the reality, and the proportion of the center control area in the renderings was obviously smaller.

The proportions of the previous major districts relative to the entire floating city are not much different from the renderings.

"Xia Duo, isn't this the central control area? Why is it so much different from the renderings? Nia asked.

"I have only completed the design of the flight control system and the repair and maintenance system, and the central control area may be greatly changed in the future, and the renderings are not accurate."

"What about the renderings of the previous partitions? Don't tell me that's not allowed! ”

"That's not it, the renderings of the previous partitions are almost what they will look like when they are finally completed, at most there are some differences in details, and the basic functions will not change."

"That's good."

Nia stroked her chest, as if relieved, and asked, "When will this place be fully built?" ”

"You don't have to worry too much about that, it can be all built in two years at most, but that's not the point, the point is that we don't have enough people to fill the city."

Through the same azure walls inside the central control layer, Xia Duo's vision seemed to penetrate the walls, extending all the way to the end of the floating city, even such a small city that can only be regarded as a pocket on the earth, it needs a lot of people!

"The maximum design capacity of this city is about 2 million, and the combined population of our two territories is less than 100,000!" Xia Duo couldn't help but sigh.

If the natural population growth rate is 2%, it will take him at least 150 years to fill this new city, and the time may be shortened when considering the magic of life extension and midwifery.

But I'm afraid it will take a hundred years to calculate.

There is no doubt that in this case, the introduction of foreign population is the main driving force of population growth, and Xia Duo thinks so and does so.

It was only last year that he introduced tens of thousands of Greyhawk tribes from the Plains of Langas, and the assimilation effect was good.

However, considering the proportion of different ethnic groups in the territory, it is impossible for Xia Duo to introduce the Langas all the time, and it is also necessary to use the Color-resistant people to reconcile and strengthen the assimilation effect.

It's just that the Langas are easy to introduce, but it's not easy to resist color.

Even if there was occasional overpopulation in various places, it was impossible for the local lord to let him take people away again and again, even though Nessera had not paid much attention to the population issue at this time.

But restricting the outflow of the population is still an instinct that has precipitated in the bloodline of the Color-resistant Lord.

Whether it is the wealth of the people or the sheltered under his command, it is better to be in your own hands than to be in someone else's.

Unless it's those territories that treat the population as a burden, but even so, there is no reason to give it away in vain, and the freedmen are counted, after all, there are not many of them, and the official territories have to scrape a layer of skin.

Therefore, Xia Duo's current plan to bring in the Nayse people is still mainly based on the purchase of slaves, supplemented by fooling the freemen, and as for the annexation of territories, he has never thought of it.

That's unrealistic.

"Nia, is there anything you can do to increase the population of our realm rapidly?"

"Langas?" Nia tentatively said a solution.

But Xia Duo shook his head, "There are enough Langas in the south, and I'm worried that they won't be able to fit in if they are brought in, is there a way for the Color-resistant people?" ”

"I want to think about it—"

Nia was really thinking about it seriously, and Xia Duo didn't urge when she saw this, but urged the water around the two of them to slowly move towards the rest of the floating city.

The visit just now was just a rough visit, and there were still many places that Xia Duo had not seen, not to mention that he had to actually test the geological data of various important inspection points.

Although the current floating city is almost in a state of weightlessness, after it is completely completed, it is a state of weightlessness and gravity.

Specifically, the floating city itself is suspended, but it is surrounded by a layer of gradient gravity field with a spherical center, which can make the residents living in the floating city feel as if they are living on the ground.

This requires that the floating city itself also has a certain support capacity, not to mention anything else, at least it can't be crushed by its own gravity.

Xia Duo's choice of transformation stone had considered the material itself, but some solidity was sacrificed for the sake of that unique azure color.

And now he is going to check the whole body, and if there is a problem, it is a big deal to rebuild one, so as not to find problems again when everything is completed in the future, and the cost of rebuilding is not one or two points.

……

Near the core energy channel in the research area, Nia was suddenly startled and excitedly told Xia Duo: "I thought of it!" ”

"What comes to mind?" Xia Duo asked as he tested.

"I've figured out how to bring in the population so quickly!"

"What's the solution?"

"It's very simple, let the great-ancestor go to the Sevington Council to apply for a development order, and then gather the people, but he didn't really open up, but sent the people to us, as long as the development continues, our people will have a continuous source of energy."

Nia said excitedly, as if she had seen the scene of countless people pouring into the southern realm and into the floating city.

In this regard, Xia Duo was quite speechless.

It is true that the Grand Arcanist can summon new lords to join him through the Council of Severton, and most ordinary people are happy to respond to the Grand Arcanist's call, and even the lords from all over the world will offer to provide manpower in order to show goodwill.

But the problem is that Savile had applied for a development order decades ago, and he had already done so.

If you want to reapply, you can only change your identity, but it is obvious that this kind of little trick is unlikely to hide from the Seven Towers, think about it, but it is a lot of trouble to really implement.

The most important thing is Saville's identity, as a student of Iolem, he blatantly defrauded the Severton Council of subsidies, and Iolum is expected to have a hard time doing it.

As for Xia Duo himself, he can be regarded as having completed the development now, but there are still some conditions that have not been completed, he is following the special process of the princess period, and now he can no longer reapply for the development order as a grand arcanist.

Of course, you can also apply for it, after all, the princess has become the "god of development and protection", and pioneering is politically correct, but there is no subsidy, and it doesn't make much sense to apply, but it is an extra burden.

However, although Nia's idea could not be implemented, it also gave Shado an inspiration, which was to negotiate with the Grand Arcanist who had already applied for the Pioneer Order to introduce the population.

Broad is a great candidate!

Even, he can train a Grand Arcanist on his own, and then apply for a pioneer in the name of the other party, and the subsidized population will be directly incorporated into the Great Xia system.
