"I'll go! Is this still a city wall?"

After seeing the drawings of the city wall, Guo Jinbao was the first to exclaim, he also knows something about architectural design!

The height of the city wall is not very high, only about ten meters, which is quite satisfactory, but the width is also ten meters. The top of the city wall not only has the normal shooting holes and defensive crenels of the city wall, but there are also two traffic trenches in the middle for the soldiers to move freely. move Place.

On the lower half of the city wall, there is also a communication trench that is six meters wide and six meters high. The communication trenches on the upper and lower parts of the city wall are interconnected, and the soldiers inside can switch freely.

As for the small door mentioned before, it was also designed at the bottom of the city wall. It was quite secretive and only existed on the inside facing the triangular area.

Moreover, there is a hidden mechanism every two hundred meters in the city wall. Once closed, a section of the city wall will be completely isolated from other walls. In this way, even if one section of the city wall is captured, it will not affect the other walls.

Others were also amazed, but soon, Guo Jinbao raised another objection:

"The design of this city wall is indeed good, and the space is large enough. If a war really breaks out, the warriors inside can switch quite flexibly, but I feel that this seems to be sacrificing part of the defense in exchange for internal space for activities. ?”

As the president of the Xinyuan Chamber of Commerce, Guo Jinbao certainly knows a lot about building materials. According to this drawing, what is the actual thickness of the wall? Fifty centimeters? Such a wall, even if it is a pure diamond rock structure, is not enough to withstand missile attacks.

As for other materials? Is there any stone in the world that is harder than diamond rock? And...such a long city wall is entirely made of diamond rock? Brother, this is a city wall that is dozens of kilometers long, not a few square meters or dozens of square meters of floor tiles!

Guo Jinbao feels that even before the end of the world, if you want to build such a long city wall made entirely of diamond rock, you will have to mobilize the power of the world. Now?

"Defense?"

Li Qingfeng was not a businessman, so how could he understand what Guo Jinbao meant. Seeing him questioning his design, he couldn't help but shake his head and said:

"I only care about the function. As for the defensive power of the built city wall, that is a matter of materials. Xiaoyi is responsible for it! It is not my responsibility!"

"Okay! If everyone has no objections, then we'll just settle on this?"

Li Yichen quickly asked at this time, and at the same time looked at Guo Jinbao strangely, what's going on with this old man? Why has he been so nervous these past two days?

"If this kind of city wall can really withstand attacks from thermal weapons or even airborne missiles, then of course there will be no problem!"

Of course Chen Tianyu heard what Guo Jinbao meant, so he answered.

"Don't worry about this! I know it well!"

Li Yichen nodded and then looked at the others.

The others looked at each other and shook their heads, indicating that they had no objections. In fact, Li Yichen didn't need to ask their opinions on this project, because whether it was a castle or a city wall, the capital of hell would be responsible for it, and Li Yichen had no plans. Jointly funded by the five major forces!

This is definitely the most expensive city wall built by Li Yichen in history. Although the materials of Yunzhong City are the same, the scope of Yunzhong City is small! Nothing like this city wall, which is nearly seventy kilometers long!

Now it seems that among all the buildings, the materials in the central part of Hell City are the cheapest, followed by those from the five major forces, and the best is Yunzhong City and the peripheral defense area to be built!

But considering that this place will become the main battlefield, it doesn't matter if it costs a little. Besides, insect carapace also accounts for a large proportion of the building materials, and wool... No, the city wall is made of insects, so it's not a loss!

Moreover, after the defense zone is built, they will have a large enough battlefield, especially on the insect side. They can disperse the insect tide to the walls on both sides of the castle, and more warriors can participate in the battle. In this way, Not only will the accumulation of materials be much faster, but more people will be able to get real exercise.

During this time, Wanshan and the others had slightly changed the news about the alien invasion and announced it directly, so everyone in the Capital of Hell also got the news.

In fact, this cannot be hidden. After all, almost everyone can see the five major forces moving materials in and out of the central base. In addition, the construction of the joint base also requires ordinary survivors to dig foundations and do some cleaning work. Even if you don't say it, , those people will also have their own guesses.

Rather than this, it would be better to make an official announcement to save them from spreading nonsense, otherwise, nothing may be spread! No matter what time it is, the spread of rumors is always the scariest thing.

Because they know the information about the alien invasion, many ordinary survivors now also want to learn some combat experience. However, there are no lone zombies around the Valley of the Dead now. This opportunity... is not easy to find!

If this defense zone is built, it would be okay to just throw in a few bugs or zombies and let them practice fighting!

Seeing that everyone had no objection to the defensive zone, Li Yichen patted Wan Shan on the shoulder:

"Lao Wan, and you stupid guy, I'll leave the early stages of this project to you!"

"No! Just wait!"

Wan Shan quickly pulled Li Yichen's arm, as if he was afraid that he would run away again:

"It's no problem in other places, but this castle here is on the path of the insect tide. There is also a small section of the city wall connecting the two castles in this position. I can't handle it without the help of military power!"

"What's wrong with military strength? I only said that I'm in charge of the military. I'm not saying that you can't control it here. Who dares to disobey you, Chang Guchuan? Find a lone wolf to greet them!"

Li Yichen glared.

"That's not what I meant!"

Wan Shan waved his hand and said:

"Is this... supposed to be a whole? Can it be divided into two parts, and the other parts are completed first, and then the insect tide section is completed?"

Hearing this, Li Yichen smiled. Without a system, this problem would be really difficult to solve, but with the help of the system, not to mention dividing it into two, it would not affect the overall solidity of the city wall!

Waving his hand casually, Li Yichen said:

"Don't worry! No problem! Do the early stage first, and do whatever you can. I will cooperate with you later!"

"Okay! Then I'll issue the mission right away!"

Wan Shan nodded, then raised his wrist and started operating on the terminal.

With the help of Intelligent Brain, the work efficiency of Hell City has been improved a hundred times. For things like calling workers, Wanshan only needs to publish a task and inform the meeting point, as well as the content of the task and the points reward. Anyone who is willing to carry out this task People will be gathering at the meeting point soon.

It was the same this time. The mission assembly point announced by Wanshan was located at the joint base. Just over half an hour later, the joint base was overwhelmed by the crowd, and... there seemed to be a lot of people coming this time... …
