Survival for the whole people: build mechas at the beginning, open Gundam

After the upgrade of the black technology castle is completed,

Information reminders also appeared in Tang Xiaofan's mind at the right time...

[Congratulations, Lord of the Castle! Your black technology castle has been upgraded to an intermediate main city, the territory directly under the castle has expanded to [-] kilometers, and the castle's sphere of influence has increased to [-] kilometers!]

[The defense value of the castle heart is increased by ten times! 】

[Your black technology castle has greatly increased its influence and reputation in the Gods and Demons Continent! 】

[Special Reminder 1: The Kingdom of Forest Giants' hatred for your black technology castle has greatly increased]

[Special Reminder 2: Dragon Nest's hatred for your black technology castle has been greatly increased]

"The territory directly under the castle with a diameter of [-] kilometers!"

Tang Xiaofan took a deep breath,

The range is really huge!
With his eyesight, he couldn't see the end, nor could he see the city wall, because the distance was too far.

What is the territory directly under the castle?
It is the area surrounded by the walls of the black technology castle,
In this area, Tang Xiaofan can build a large number of castle buildings at will.

And the area within a thousand kilometers in diameter outside the castle wall belongs to the sphere of influence of his castle, and invading this area is tantamount to making an enemy of his castle power.

"Such a large direct territory!"

"It's not so easy to defend!"

With the size of Tang Xiaofan's current castle army, it is very difficult to defend the city wall with a diameter of [-] kilometers.

After all, the circumference of the city wall is more than 800 kilometers.

The number of troops under his command is only more than [-] if only counting the troops in the castle.

Even if it's all spread out on the city wall,
It is equivalent to arranging more than 100 people per kilometer.
More than 100 people guard the one-kilometer city wall.

This is very exaggerated!
For a castle territory as big as Tang Xiaofan's, at least one hundred thousand troops and one million castle citizens are required to be considered normal.

Unfortunately, Tang Xiaofan's development speed is too fast,

The population growth rate of the castle cannot keep up with the upgrade rate of the castle.

This also caused his castle territory to be exaggeratedly large, but the population of the castle was pitifully small.

Although compared to other castle masters, his castle has a very large number of troops, but it would appear sparsely staffed in such a large territory.

Not just sparsely populated.

There are also very few buildings in the castle.

Seeing that there are some buildings around the main castle,
A few kilometers away, and extending to the city wall hundreds of miles away, there is a vast expanse of white space in this area. It can be said that there is nothing but floor tiles.

It's definitely not going to work,
How could such a castle look like a main city?
It's more like a tribe.

Tang Xiaofan turned his head to look at Olivia, the spirit of the elf mother tree beside him,

Tell her about the castle,

After listening to Olivia, she thought for a while and said, "My lord, why don't we move all the elves from our tribe and the goblins from the underground world here?"

In the elf tribe located more than 100 kilometers away,
There are also about three or four thousand natural elves, all of whom were bred by Olivia herself, and belong to the aborigines of the Gods and Demons Continent.

As for the underground world,

A goblin kingdom, plus a large goblin tribe,

In total, there are nearly [-] goblins.

If all the elves and goblins are moved here, the population of Tang Xiaofan's castle will exceed 13.

In addition, a group of dwarves can be migrated from the dwarf kingdom to the black technology castle.

In this way, the population of the Black Technology Castle can reach about 14.

In this way, the huge black technology castle will not look so empty,
And the defense will be stronger.

Tang Xiaofan shook his head and did not agree.

After thinking for a while, he said: "I have issued an order before that non-farmers are not allowed to live in the inner city."

"My family of farmers will continue to expand in the future, at least tens of millions of people."

"The current urban area is not enough for future development. So there is no rush."

"As for the elves, let's develop in their own territory. In the future, it will also be an important city for our black technology dynasty, so we can't give up easily."

Hearing Tang Xiaofan's words,
A sweet smile suddenly appeared on Olivia's cheeks
It's a pity that I can't live in the core area of ​​the black technology castle.

But Tang Xiaofan's arrangement for the elf tribe shows that their elves have a high status in Tang Xiaofan's heart.

Although not as good as the farmers, but far stronger than other races,
that's enough.

Tang Xiaofan did what he could think of, recruited Nong Yi, and continued to expand the residential area and entertainment area.

Because now the entire black technology castle is a military-based city,

Moreover, all people's livelihood is automatically transformed through the factory,

There is no need for too many industrial workers at all,

So the main life needs are to sleep, eat and play,
Therefore, the whole city is divided into different sections according to the living gathering areas, and each section includes a series of functions such as eating, drinking, playing, living and so on.

It is the large-scale stadium currently under construction, which will become the coordinate building of the city.
Such as large basketball stadiums, rugby stadiums, and various movie theaters, etc.

It is relatively simple to plan,
Moreover, in terms of transportation, unmanned trams and rail transit have conveniently solved the problem of travel.

So a city of 10 people, although busy, is not chaotic at all.

Everyone is working step by step and in an orderly manner.

Then, Tang Xiaofan took out the drawings obtained after the castle army captured the dwarf kingdom.

He wanted to see if there were drawings of the city walls.

If not, go to the trading channel to buy a few. Anyway, he has an incredible amount of resources now, and buying a few blueprints of architecture is nothing at all.

He counted,
It was found that there are more than 70 blueprints harvested in total.
All are unidentified drawings.

He did not hesitate to identify it immediately, and at the same time, he checked the upgraded information of the Black Technology Castle...

【Black Technology Castle】

[Current level, intermediate main city]

[Special Buildings: Farmer's Factory, Elven Mother Tree, Space Teleportation Magic Array, Bright Monastery]

[Upgrade requirements: 700 million units of wood, 500 million units of stone, and 200 million units of refined iron. 】

[Next level: Advanced Main City]

【Current status: invincible】

"The next level, the castle is upgraded to a high-level main city!"

"What I'm short of now is wood and stone. The wood is short of more than 600 million units, and the stone is still short of more than 200 million units. As for refined iron, I have more than 430 million units. The upgrade requirements have been met!"

"That is to say,"

"As long as the wood and stone meet the upgrade requirements,"

"My black technology castle can be upgraded again!"

Tang Xiaofan grinned,
Then turn off the message frame of the castle,

Then he took another look at his existing reserve of soul stones.

1292185 soul stones,
"Get rid of the soul stone I stored before."

"This time I captured the Dwarf Kingdom, and I harvested a total of about 14 soul stones! This harvest is far more than when I captured the Goblin Kingdom."

"Sure enough, the dwarf kingdom is much richer than the goblin kingdom!"

"And, I can upgrade the farmer's factory to level ten!"

Originally, Tang Xiaofan didn't plan to upgrade the farmer's factory before the arrival of the alliance army.

Because he was worried about not having enough soul stones,
It is impossible to let the city of the sky fire to its heart's content.

But now he has nearly [-] million soul stones in reserve.

Even if he upgrades a million soul stones, he still has 30 soul stones left.

and he believed,
The sky city that has been transformed should not be used to the point where he consumes soul stones, and he can get more soul stones in the future.

That is,

At that time, even if he consumes a lot of soul stones to upgrade the farmer's factory, it doesn't matter, and it won't affect the war against the castle alliance army.

"Not urgent!"

"There is still time to continue to store soul stones."

"After saving some more soul stones, then consider whether to upgrade the farmer's factory."
