The mountains of Nanman are where Garuda Fort was chosen.

Next to the river, a small dock for docking boats has been built, and more than ten boats are carrying supplies back and forth.

At the foot of the hillside, the pottery bricks and stones needed to build the fortress have already been piled into square hills. The amount is definitely more than enough to build a city wall, not to mention a fortress.

However, Beishan Amu did not instruct her tribesmen to start building the fortress because they did not know how to build it yet.

There are quite a few fortresses and cities built by the Haotian tribe, and there are all kinds of them.

For example, Salt Rock City and Haotian Castle were built around a mountain.

Another example is the defensive facilities built in Netherworld Valley.

Also, the new city built by Garuda Camp on the bank of Haotian River.

It can be said that Beishan Amu knows how to build a fortress on flat land, in a valley, or around a mountain, but she cannot yet build a fortress on a hillside.

This hillside is sloping. How to build a fortress?

In fact, without Zhao Hao, they would not be able to build any fortresses or cities, because humans in ancient times have not yet developed to the level of building cities and fortresses, including the Taihua tribe. The reason why they built cities and fortresses is that

It is not developed to that level, but the result of the so-called divine teachings.

Zhao Hao has naturally seen the fortresses built on this hillside, and he has seen many types.

The reason why he did not rush to order people to start construction was because he wanted to design a typical example so that the generals of the Eighth Battalion could imitate it.

After all, there are not just one or two fortresses that need to be built in the southern barbarian mountains in the future, and it is impossible for him to guide them one by one on site. Therefore, he must make typical examples of fortresses built in various terrains, so that

, the generals of the Eighth Battalion can imitate the buildings based on these examples.

Now, there are good examples of forts built around a hill and in a valley. There are even examples of small forts built on top of mountains, but not on hillsides.

So? What kind of structure should be chosen for a fortress built on a hillside?

Zhao Hao thought hard for a long time, but decided to use a ladder structure? That is, like a ladder, he climbed up one step at a time.

Of course? This ladder is not a standard ladder with equal spacing. The so-called ladder structure must determine the length of a ladder according to the terrain.

To put it simply, if it is a severely sloping place, then build it step by step according to the span of the feet? If it is a relatively gentle place? Then dig it into a platform as long as you can.

.

This structure is quite complicated and must be explained carefully. After the personnel and materials were almost ready, Zhao Hao recruited Beishan Amu, Ji Rushuang and others into the large tent of the temporary camp and began to explain.

This time? Due to limited transportation capacity, we cannot store too many supplies. The other side is not a wild jungle, but the same southern barbarian mountains. We cannot transport more supplies by land, so Zhao Hao did not organize too many manpower.

? Roughly speaking? That is, there are 400 elites in the Garuda camp and 200 guards in the Guards camp, a total of about 600 people.

In the big tent, there were not many people who could come to listen to his explanation, namely Beishan Amu and her two captains, as well as Ji Rushuang and two captains from the personal guard battalion.

After everyone arrived, Zhao Hao picked up a brush and began to draw on a sheepskin that had been fixed vertically behind him.

The reason why he used sheepskin to draw sketches was because there was no way around it, because there was no such thing as paper at the moment. Of course, the sheepskin would not be wasted. It could still be used after being washed with water, but the inside would be a little dark.

That's all.

What he drew was not complicated, just a rough diagram of a hillside and a few steps.

After finishing the painting, he pointed to the schematic diagram of the hillside and introduced: "This is the hillside where the fortress is to be built outside. As we all know, this hillside is sloping, so how to build a fortress on it? It's very simple, we will use this

This kind of step structure is used in the city walls on both sides. There is this kind of step structure in the Netherworld Valley. You may still remember it. However, this time we not only repair the steps, but also repair the walls on both sides and the bottom.

We need to build the base of the city wall."

When he said this, everyone roughly understood.

Everyone has naturally seen the steps in the Netherworld Valley. Of course, the steps there are paved with stones and ceramic tiles along the hillside, and are not built to look like a city wall.

However, this was enough for them to understand the shape of the stepped city wall.

Immediately afterwards, Zhao Hao continued to explain: "You also need to dig a foundation under this stepped city wall. However, the digging of the foundation and the filling of the city wall are similar to those of ordinary city walls. You can just dig and fill them directly. It's just that the city wall

The top of it needs to be built into the shape of steps. Also, the steps do not have to be built so evenly all the way up. In places where the hillsides are relatively gentle, we can also build some platforms to build arrow towers or stand people."

As he spoke, he drew a long, flat line on top of the original steps, and then added a few more steps on top of the line.

After he explained this, everyone basically understood how to build the city wall on the hillside.

Immediately afterwards, he continued to explain: "As for the barracks, it also depends on the terrain of the hillside. This hillside is not very steep, and many places are relatively gentle. In those gentle places, we can dig out piece after piece.

The flat land is used to build barracks, which is similar to Salt Rock City and Haotian Castle."

At this point, the explanation of how to build a fortress on a hillside has been roughly explained, and everyone's faces also showed a look of surprise.

Zhao Hao saw this, nodded slightly, and then asked: "Do you have any questions?"

Unexpectedly, someone actually has a problem.

As soon as he finished speaking, Zhao Yi asked carefully: "What if we dig out the Sky-Mending Divine Stone?"

this!

Zhao Hao has indeed not considered this issue, because his purpose this time is to build a fortress to protect the sacred tree, not to dig up the sacred stone.

Speaking of which, this is really possible, because there are many God-Mending Stones around the sacred tree, and there is no pattern in the depth of the God-Mending Stones. It is really possible to dig out the God-Mending Gods when digging the foundations of city walls and barracks.

Stone comes.

Zhao Hao thought for a while and then said decisively: "Bury it wherever you dug it out, just bury it deeper. This time, we are not digging to repair the God Stone, but to preserve the God Tree, so we are digging

Don’t take out the Heaven-Mending Divine Stone when you arrive, just bury it back.”

Next, everyone had no problem. Zhao Hao took everyone to the hillside outside and explained on the spot according to the terrain. Where steps need to be built, where platforms need to be dug, and where the barracks need to be built, he has done it all.

Detailed explanation.

After everyone roughly figured it out, Garuda Fort officially started construction. Although there were not as many people building the fort this time as there were in Netherworld Valley, the construction speed was still quite fast, because this time there was no such thing as Netherworld Valley.

The city wall is astonishingly high. Except for the step-shaped city wall, which is a little more troublesome, the rest is basically the same as building a fortress on flat ground.

About a month later, a majestic fortress appeared on the hillside where the sacred tree was located, and Zhao Hao took Ji Rushuang, brother and sister, and began to plan the road to Haotian Castle while clearing away the strange beasts and beings close to the sacred beasts along the way.
