Apocalyptic Garbage Sorting System

"I'm going! Is this still a city wall?"

After seeing the drawings of the city wall, Guo Jinbao was the first to marvel that he also knew some 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 shooting holes and defensive crevices of the normal city wall, but also has two traffic trenches in the middle for the freedom of the soldiers. move Place.

In the lower half of the city wall, there is also a traffic trench with a width of six meters and a height of six meters. The traffic trenches on the half and the lower half of the city wall are interconnected, and the soldiers inside can switch freely.

As for the small door mentioned earlier, it was also designed at the bottom of the city wall, quite secretive, and only found on the inner side of the triangle 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 the 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 objections:

"The design of this city wall is really good, the space is large enough, if there is a war, the soldiers inside can switch quite flexibly, but I think this seems to be sacrificing part of the defense force in exchange for internal activity space. ?"

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

As for other materials? Is there any stone harder than diamond rock in this world? And... all diamond rocks are used for such a long wall? Brother, this is a city wall tens of kilometers long, not a few square meters or more than ten square meters of floor tiles!

Guo Jinbao felt that even before the end of the world, if he wanted to build such a long wall made of diamond rock, he would have to use global power to make it possible. Now?

"Defensive power?"

Li Qingfeng is not a businessman. How can he understand Guo Jinbao's meaning? Seeing him questioning his design, he couldn't help shook his head and said:

"I only care about the function. As for the defense of the built city wall, it is a matter of materials, Xiao Yi is in charge! It is not my responsibility!"

"Okay! If everyone has no opinion, then we'll settle it down like this?"

Li Yichen hurriedly asked at this time, and at the same time looked at Guo Jinbao a little strangely, what's the situation of this old man, why has he been so nervous these past two days?

"If this kind of city wall can really withstand the attacks of thermal weapons or even airborne missiles, then it will be fine!"

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

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

Li Yichen nodded and said, then looked at the others.

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

This is definitely the most expensive city wall ever built by Li Yichen. Although the materials of Yunzhong City are the same, the scope of Yunzhong City is small! It looks like this city wall, nearly seventy kilometers long!

It now seems that among all the buildings, the materials in the middle of the **** capital are the cheapest, followed by the five major forces, and then the best is the cloud city and the outskirts to be built!

But thinking about it, this place will become the main battlefield. It doesn't matter if it costs a little bit. Moreover, among the building materials, the carapace of insects also accounts for a large proportion. Wool...No, the wall is on the insects, and it is not a loss!

Moreover, after this defense zone is completed, they will have a large enough battlefield, especially the insects, which can spread the insects to the walls on both sides of the castle, so that more fighters can participate in the battle. Not only will the accumulation of materials accelerate a lot, more people can get real exercise.

During this period of time, after Wanshan and the others had slightly changed the news of the alien invasion, they announced it directly, so everyone in the capital of **** also got the news.

In fact, I can’t hide this. After all, almost everyone can see that the five major forces move in and out of the central base. In addition, the construction of the joint base requires ordinary survivors to dig foundations and do some clean-up work, even if you don’t say it. , Those people will have their own guesses.

If this is the case, it is better to be announced by the government, and the province will pass it through, otherwise, it will not necessarily be heard! No matter when, the spread of rumors is always the most terrible.

Knowing the information about the alien invasion, many ordinary survivors now also want to learn about combat experience, but now there are no zombies around the Death Army Valley, this opportunity...not easy to find!

If this defense area is completed, just throw a few bugs or zombies, and let them practice fighting.

Seeing everyone expressing no objection to the defense zone, Li Yichen patted Wanshan on the shoulder:

"Old Wan, there is also a silly big one, the early stage of this project is left to you!"

"No! Wait a while!"

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

"Other places are okay, but here is the castle, but on the path of the insect wave, there is also a wall connecting the two castles. There is also a short section of it in this position. Without the help of military forces, I can't figure it out!"

"What's wrong with the military power? I only said that I was in charge of the military, but I didn't mean that you can't control it. Which of Chang Guchuan would dare not listen to you? Call them a lone wolf!"

Li Yichen stared.

"I didn't mean that!"

Wan Shan waved his hand:

"This...is it to be a whole? Can it be divided into two parts, first to complete the other parts, and finally to complete the worm wave section?"

Hearing this, Li Yichen smiled. If there is no system for this problem, it is really difficult to handle, but with the help of the system, let alone divide it into two, twenty times will not affect the overall solidity of the city wall!

Randomly waved his hand, Li Yichen said:

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

"Okay! Then I will post the task immediately!"

Wan Shan nodded, then raised his wrist and began to operate on the terminal.

With Wisdom Brain, the work efficiency of the Hell Capital has been improved by a hundredfold. For things like this kind of gathering of workers, Wanshan only needs to post a task to inform the assembly point, the content of the task and the reward points, and those who are willing to perform this task People will go to the assembly point soon.

It was the same this time. The mission assembly point announced by Wanshan was set up on the joint base. Just over half an hour later, the joint base was flooded with crowds, and... this time there seemed to be a lot of people coming... …
