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

"A direct territory with a diameter of [-] kilometers!?"

Tang Xiaofan looked at the castle he had just upgraded, and couldn't help but take a deep breath.

This area is really too big!
There is only one city, with a diameter of five hundred kilometers.

Converted into an area, that is about 19 square kilometers.

For such a large city, it would not be a problem to live in hundreds of millions of people.

What's more, after the black technology castle was upgraded to a high-level main city, its sphere of influence has expanded to two thousand kilometers.

That is, with the castle as the center,
The area within a radius of [-] kilometers is the sphere of influence of the black technology castle.

This is horrible!
And Tang Xiaofan has reason to believe that,

When his castle was upgraded to a royal capital,

The forest with a diameter of thousands of kilometers will all be included in the sphere of influence of his castle.

"Before I thought,"

"With a population of more than [-], my castle finally has some popularity,"

"But now after upgrading to the high-level main city, the territory of the castle has become even more empty, and there are blank areas everywhere. It is not an exaggeration to say that there are thousands of miles of uninhabited people!"

Tang Xiaofan stands in the sky above the black technology castle,
Olivia was still by his side.

Both of them looked down at the black technology castle below,

The most eye-catching thing is naturally Tang Xiaofan's core main castle, which is 200 meters high, and the whole body is made of white jade, exuding a holy light.

Whether it is day or night, it is the brightest star in the forest.

Followed by the Farmer's Factory, Elven Mother Tree and Holy Light Monastery and other arms buildings.

They are located in the core area of ​​the castle,
The importance cannot be overstated.

The second most eye-catching are the four walls of the Black Technology Castle.
From the inside to the outside, the entire castle's territory is divided into four areas.

After Tang Xiaofan upgraded the black technology castle to a high-level main city, the four city walls also undergone tremendous changes, becoming taller, wider, and more majestic.

rough estimate,

They now reach a height of about 300 meters.

Like the walls of the city of God.

Gives a feeling of unattainable

And, they're not just taller and wider, they're also much more defensive.

Take the outermost main city wall as an example, there are a lot of special metals mixed in it, and all kinds of anti-magic runes are densely covered, making its defense very terrifying.

The city wall of the intermediate main city is difficult for a level [-] strongman to break through.

nowadays,
It evolved into the walls of the high-level main city.

Even if a level 21 powerhouse wants to destroy it, it is not an easy task.

It can be said that as long as Tang Xiaofan closes all the city gates, it will be difficult for the [-] million troops of those alliances to enter.

Flying units can rely on flying ability to enter his castle,
However, the troops on land may only rely on the tactics of the human wall to climb up.

The upgrade of the black technology castle has many benefits.

But the shortcomings are also obvious.
It's just that the territory directly under it has become too large.

With Tang Xiaofan's current castle population, it is completely impossible to fully defend a territory with a diameter of [-] kilometers.Even if those goblins and dwarves are trying their best to build various defensive buildings, it is still very difficult.

Olivia looked at the upgraded black technology castle,

After a long silence, he said:

"Only if your castle's population reaches at least one million can you defend the outermost city walls in all directions."

At this time, in Olivia's emerald green eyes,

Filled with the color of shock.

Compared with today's black technology castle,

Their previous elf tribe was really pitifully small.

Even their elven tribe's residence no longer exists after the black technology castle was upgraded to a high-level main city.

the reason is simple,
In the past, the elf tribe was about 180 kilometers away from the black technology castle.
And now,

The territory directly under the Black Technology Castle has a radius of 250 kilometers alone...

That is to say, the outermost wall of the castle has been pushed horizontally to the original residence of the elf tribe, and countless trees, rocks, lakes, and even mountains have disappeared directly along the way.

Everything within this range has become a flat ground paved with bluestone slabs.

The same is true for the original residence of the elf tribe.

has disappeared.

The area where it used to be has become part of the territory directly under the Black Technology Castle.

"Your castle,"

"A giant city comparable to the Elven Empire!"

Olivia said with emotion.

Of course, she was referring to the size of the black technology castle.

In terms of the prosperity of the city, the black technology castle is definitely not as good as horses.

The main reason is that the population is too small.

This is a problem that needs to be solved!
Originally, Tang Xiaofan thought that summoning [-] soldiers could temporarily make up for the low population of the Black Technology Castle.But now he realizes that he is still too naive. After upgrading the high-level main city and expanding its area dozens of times,
Not to mention a population of 10, even a population of hundreds of thousands or millions would not be able to fill the entire castle.

Tang Xiaofan knew very well,

The direct reason for this problem is that his upgrade speed is too fast.

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

If it were those castle masters who were slow to upgrade, they would have more time to recruit troops, conquer local forces, and conquer the population of local forces.

As for Tang Xiaofan,
The upgrade was too fast, causing him to lack the time to expand the population.

Tang Xiaofan said: "The population problem will be solved later, after all, there is no way to add hundreds of thousands of troops out of thin air. After the castle is upgraded to a king's capital, this situation will still happen again."

"Now the black technology castle's top priority."

"It is to eliminate the dragon's nest and establish a dynasty."

"After the black technology heaven is established, we will find a way to replenish the population of the castle."

There are various ways to replenish the population,
First, recruit arms.

Second, plunder native intelligent creatures
Third, natural breeding.

The third method, which is long-term family planning, will not see results in the short term.

Recruiting arms is the key point,
Predation of native intelligent life forms is also important.

Kill those who refuse to bow their heads and surrender,
Those who are obedient will be plundered into the castle and transformed into his believers, adding bricks and tiles to his path of faith.

Of course, Tang Xiaofan is not plundering all intelligent creatures,

He doesn't want intelligent beings that are in the dark, evil alignment.

Because this will cause confusion in the camp of the castle,
Not worth the candle.

Olivia thought for a while, and said to Tang Xiaofan, "My lord, there are tribes of elves in the Bolili Highland, and there are also nomadic grassland elves in the Karami Prairie."

"How about I go and see if I can bring them to your castle?"

"Being not!"

Tang Xiaofan shook his head and said: "The war is coming soon, you'd better stay in the castle."

"Besides, even if you go there in person, they might not necessarily listen to you."

"Even if you are an elf mother tree and a demigod!"

After pondering for a while, Tang Xiaofan said: "After I establish a black technology paradise and increase my influence and reputation in the Gods and Demons Continent, the chance of success will be greater!"

Tang Xiaofan believed,
A kingdom recognized by the laws of the world,
It must be able to increase the attractiveness to native intelligent creatures!
After the ceremony, kill some disobedient ones, and the rest will know what to do.

After hearing Tang Xiaofan's words,

Olivia also nodded:
He agrees with Tang Xiaofan's words very much.

time passed quickly,
In the blink of an eye, two days have passed.

Tang Xiaofan's armies have already swept across the area around the castle, thousands of kilometers away.

Killed nearly a million wild monsters,

There are more than 200 large and small local forces destroyed,
A total of more than 200 million units of food, more than 500 million kinds of monster materials, more than 300 soul stones and more than [-] various blueprints have been harvested.

In addition, there are wood, stone, and refined iron, totaling more than 600 million units.

These two days can be said to be hunting and carnival!
His castle army killed wild monsters and local forces within thousands of kilometers to almost despair.

At the same time, this also makes it difficult to see wild monsters and native intelligent creatures around the black technology castle.

The only way to deal with wild monsters is to kill them.

As for native intelligent creatures,

Tang Xiaofan didn't kill them all,
The ones who were killed were all diehards, and they belonged to the kind that even the angel of the heart, Tiga, could contend with the magic of faith.

The surviving native intelligent creatures were taken captive into the black technology castle and became the second batch of aborigines under Tang Xiaofan's command. At the same time, they were all transformed into believers.

two days passed,

The population of Tang Xiaofan's castle can reach 20:
The number of 20 is absolutely outrageous compared to those castle masters in the castle forces, and it is even larger than the population of the former dwarf kingdom and the forest giant kingdom.

As an ordinary dynasty-level force, it is enough.

However, Tang Xiaofan's black technology heaven is a dynasty that wants to rule the entire forest.

A population of 20 is naturally not enough.
One million is not too much for him.

However, Tang Xiaofan is not in a hurry,
This only wiped out the surrounding area within thousands of kilometers,

The entire forest has a diameter of five or six thousand kilometers, and there is still a very large area waiting for him to clear it.

Believe, after he has cleared the entire forest,
The population of his castle is also the number of his followers, at least hundreds of thousands.

Maybe there is hope to break through 100 million.
