There is a biological group in the Great Wilderness called pangolins. Pen, fun, pavilion www. biquge。 infoThis pangolin is not like a protected animal on earth, which can only burrow in the soil.

The pangolins of the Great Wilderness are comparable in size to elephants, each one looks like an awl, the whole body is covered with heavy armor, and the head has horns that are harder than steel. The main purpose of this collision angle is to match their huge size and knock the boulder out of the crack.

And in front of its body, there are four claws.

These claws can easily make marks more than an inch deep on the bluestone.

Once the clamming horns on their heads knock the stone out of the cracks, their claws are able to use the cracks to dig a hole in the stone.

If the walls of the Great Wilderness are still like the blue bricks on the outside and rammed earth on the inside, the pangolin only needs to gently knock away the outer layer of green bricks and then enter the city wall.

At that time, the fragile rammed earth really couldn't stop them from going wherever they wanted.

Therefore, if you want to defend against the sneak attack of pangolins, you can only thicken the city wall, and the entire city wall is not rammed with any earth, and all the walls are made of concrete and blue bricks.

If it weren't for the limited technology now, without vibrating rods and enough steel bars, Wang Hao would even have thought about making the entire Hwaseong into a reinforced concrete structure.

Without vibrators, there are too many air bubbles in the cement to be poured on a large scale, and the firmness is no stronger than a mix and match of concrete and brick.

As for steel bars, although with coal, Hwaseong can smelt iron ore and obtain metallic iron, but it is still impossible to produce steel bars in large quantities at present, so some steel bars can only be added in some important places.

The lower part of Hwaseong's castle wall has a width of 5 meters, so that whatever you have can be transported inside the castle wall.

As for the remaining twenty-five meters wide, they are all solid. Such a wide solid brick wall, let alone a pangolin, even if a giant holds a sledgehammer, it will have to be blasted day and night for several days to smash through.

After all, when the entire city wall is connected by concrete, although the force point is only a little after being attacked, the force will be dispersed over the entire city wall. As a result, once the walls of Hwaseong are built, it is basically impossible to be destroyed by brute force.

As for the distance of more than 20 meters of the city wall, except for the outer wall, which reaches a thickness of one meter, the rest of the internal space is empty.

That's right, the five meters above the city wall, the inside is empty.

And in those places, densely packed with countless firing ports.

Some of these firing ports are flat, some are diagonally facing downward, and some are facing the sky.

The system takes into account those giant birds that come from all directions in the air, so these firing ports can not only attack the enemy on the ground, but also basically achieve 360 degrees of defense without dead angles even in the air.

In this way, when the monsters attack the city, people can attack enemies in various places outside as long as they hide behind the brick wall bunkers that are up to one meter thick.

As for whether the creatures that can fly or climb walls will crawl in and attack people along these firing ports, there is no need to worry at all.

As people of the Great Wilderness, if they can't even deal with some creatures smaller than themselves, then they won't have the face to live in the Great Wilderness.

Different living environments create different civilizations.

The environment of the Great Wilderness forced Wang Hao to build such a fortress that could only be used for battle.

The total length of the solid city wall is as long as eight kilometers, and the amount of cement and brick consumed is simply astronomical.

If left on Earth, if nothing else, the materials it needs alone can plunge a small country with a population of millions into an economic crisis.

In the Great Wilderness, a place with low productivity and low level of science and technology, the manpower and material resources to be consumed will be even more desperate.

However, the Great Wilderness also has the advantages of the Great Wilderness.

First of all, in the Great Wilderness, the greatest pursuit of human beings is to be able to eat, clothe, and have a safe living environment.

This can be provided by Hwaseong.

In particular, after the first batch of wheat in the Grand Canyon matured and grew amazingly, Hwaseong had a say in food.

And the most important point is that the economy of Hwaseong is not regulated by the market, but by Hwaseong.

Today, Huacheng says that wheat is a pack of ten copper plates, then it is a pack of ten copper plates, which does not mean that the market demand for wheat will rise if the demand for wheat is large, and the price will fall if the demand is small.

The deformed system has created a deformed economy. However, with the help of this economy, as long as Wang Hao can provide food, theoretically speaking, he can gather the entire Great Wilderness and hundreds of millions of people to contribute to the construction of Huacheng.

Today's Hwaseong, although it has not yet taken shape, if you look at it from above, Hwaseong is like an ant nest, and countless wooden carts full of bricks are transported by carloads of red bricks through the asphalt road of Hwaseong.

And the bricks of this cart can be exchanged for dried meat provided by Hwaseong, or bags of wheat.

At present, the construction of Hwaseong Fortress does not require too many manpower, and some heavy manual labor can be done by savages and slaves.

What Hwaseong needed was a huge amount of materials.

The bricks that were stored last year had already piled up, but now in Wang Hao's opinion, the number of these red bricks can't even be built for one-tenth of the city wall.

On the side of Shishan, the number of vertical kilns has been expanded to more than 20, but despite this, the supply of cement fired every day is still in short supply.

However, more than 20 vertical kilns are already the limit of Hwaseong.

There is no way, coal is needed to burn cement, and the heat of ordinary wood after burning is not enough to burn cement.

But the excavation and transportation of coal mines also require manpower and time.

Those slaves from Jiulong Mountain, after being trained by Wang Ba, have adapted to life in Hwaseong.

After a period of training, they have become semi-skilled bricklayers.

The 500 slaves were promised that if they could build the walls of Hwaseong, they would be freed from slavery and become free again.

Therefore, every day before dawn, these slaves would consciously get up and start building the walls of Hwaseong.

Every day, when the sky was completely out of sight, they would stop the brick knives in their hands.
