And with the current strength of his tribe, there is no way to confront the large army of orcs head-on, so the most effective way to protect the security of the territory is to build a city in the narrowest part of this mountain pass, build a city wall, and dig a trench, which is the most effective way to protect the security of the territory at present.

But these natives can't even build a house, so let them build a city wall, Xiao Feng feels that this is difficult for a strong man, but this city wall can't be repaired.

The first few times I came into contact with the orcs, the team of the half-orcs was not large, and he also killed them all, and he didn't let go of one, so the half-orcs nest should not know that there is a human tribe here.

But now that it has entered spring, it is about to enter summer, Xiao Feng doesn't know how far the war between the orcs and several other human empires is going, if the orc army has already destroyed those human countries and comes back to consolidate the territory and expand the scope of inspection, it is very likely that the existence of their tribe will be discovered.

When the time comes, there will be no need for many people, as long as a team of 1,000 people is sent over, his tribe may disappear and will not be able to hold on.

Therefore, the city wall must be built, but how to build it, how high it is, and how many people to use, he does not have a score, after all, the knowledge of civil engineering is not something he can find a few books to read, or simply learn on the Internet.

There are too many knowledge about the number of workers, quality, building materials, construction methods, etc., and in the modern world, maybe a few rural construction teams can complete the work, and it is definitely a big project to get it to this world.

Xiao Feng sat on a big stone at the pass, looking at the pass in front of him that was more than 100 meters wide, this is just the narrowest place where the mountain extends, and the terrain is relatively flat, as long as a wall is built here, the southern peninsula can be locked, but how should this wall be built?

"You want to build walls here?"

The low voice startled Xiao Feng, he was thinking too much before, he really didn't notice that there was another person around him, and when he turned his head, it was Knight Kyle.

This guy is tall, blonde, and should have been a handsome guy when he was young, but after the baptism of the years, he is now full of vicissitudes, and the scar on his face did not make him hideous, but a little more mature and steady.

A winter of recuperation, so that his mental state looks good, although it is spring, there is no war, but he is still wearing armor, the damage on the armor, has been repaired, and it has been carefully maintained, it can be seen that although he has been under house arrest for a winter, he has always reminded him to remember his identity, a very proud guy.

Although it is under house arrest, as long as he doesn't make trouble and doesn't run around, Xiao Feng doesn't let people imprison his personal freedom, so it's not unusual for him to appear here.

"Aren't you with the Duchess?"

This Knight Kyle has always been by the duchess's side before, but this time he is alone, Xiao Feng is quite strange.

"She was with Birodis, and the ladies were talking about topics that I couldn't get involved in. ”

Xiao Feng nodded, thinking that this guy was a professional soldier, so he would definitely be able to see the danger here, after all, he was more experienced than himself, so he might as well ask him.

"That's right, I want to build a wall here. ”

"It's a good idea, it's a treacherous terrain, it's easy to defend and it's hard to attack, and the terrain is low in the north and high in the south, as long as we build a wall here, if the orcs come, we can block them to the north, and there is a big river next to it, as far as I know, they are not good at shipbuilding, and they are not proficient in water warfare. Once the walls are built here, your tribe can grow in peace and security in the south. ”

is worthy of being a veteran oilman, Xiao Feng's strategy, he can see through it at a glance, Xiao Feng nodded.

"But how do you build the city wall? My tribe is full of natives, their civilization is very low, and they can't even repair their houses, so I really don't know how to teach them how to build the city wall, and building the city wall is a big project, just mining stones, it takes a lot of manpower, and there are only a few people in my tribe, and they can't keep busy at all. ”

Xiao Feng didn't think about using the reinforced concrete of the modern world to build the city wall, the process is simple, and there is no need to mine stones, which greatly reduces the cost and the speed is fast, but the process is simple It is for modern construction workers, for these natives, it is simply a fantasy.

Even if Xiao Feng brought reinforced concrete, would they roll the steel bars? Will they mix and pour concrete?

If there were no steel bars, how many meters would the city wall be built with concrete?

If you teach the natives to burn bricks, it is difficult to kill these stupid people who don't even know how to make billets and verticals, not to mention the technology of controlling the temperature of the brick kiln, for modern human beings, these jobs seem to be very simple, but they are all generations of human ancestors, after thousands of years of accumulation and exploration of experience, it is these experiences that have created modern human civilization.

And the natives here have just taken the first step from the trees to the ground, as for any civilization, let alone mention.

So after thinking about it, Xiao Feng can only think of the earthen method of building cities in ancient Europe, using stones, and the cost of mining stones is high.

Headache, how to build a city wall to get out?

After listening to Xiao Feng's question, Knight Kyle felt that it was not difficult: "Actually, if we don't use stone, we can use wood." ”

"Build walls out of wood?"

"Yes, you see that this mountain is full of tall trees, cut down some logs, dig a pit in the ground and bury the logs side by side, and at a distance behind them, also bury a row of these logs, and then fill in the earth between the two rows of logs, and tamp it down, so that the city wall will not be?"

Kyle's words made Xiao Feng's eyes light up, why didn't he think of it? This is indeed a method, just like the concept of modern pouring concrete walls, using logs on both sides is equivalent to pouring the formwork before, and then filling in the middle and tamping, it is equivalent to pouring concrete in the middle of the formwork, the only difference is that after the concrete is poured and knotted, the formwork must be removed, and these logs do not need to be dismantled.

The wall built in this way will save a lot of manpower and material costs, and the only disadvantage is that the city wall is not too forbidden to burn, and if the other party uses fire attack, it will be very troublesome.

But now I can't take care of it so much, let's put up the city wall first, after the city wall is repaired, it can also play a very effective role in suggesting to the people of his tribe, at least the sense of security will be greatly improved.

With a sense of security, these people can work harder.

"You're a very good idea, have you ever had any experience building a wall like this before?"
