Building an Empire in the Apocalypse

If they cannot be reinforced in time, the further down they go, the less support points these floors built by Lu Feng will have.

So he built several heavy pillars in the middle of this floor. Most of these weight-bearing pillars are made of reinforced concrete, but they have been processed by Lu Feng in the system, so the weight and strength of these pillars are extraordinary.

Lu Feng even used some missiles from the missile base and conducted a small blasting experiment on the square above the missile base before starting construction.

Because these pillars are to be buried heavily underground, Lu Feng is also very careful about the strength of these pillars. Before these pillars were seen, each one was about 10 centimeters thick.

Lu Feng used anti-tank missile mortar shells and even more than 10 grenades, and concentrated blasting with these firepower, but they could not cause any damage to the pillars he built.

Even some minor scratches did not appear, and Lu Feng was quite satisfied with the solidity, because his 10-centimeter column was not a load-bearing column but a part of a load-bearing column.

The load-bearing column that Lu Feng wanted to build was 30 of these 10-centimeter columns tied together, which was the load-bearing column that Lu Feng needed.

And just under a Qingshan base, Lu Feng had already used 15 load-bearing columns.

The diameter of each column can basically reach about 1.5 meters. With this quality of load-bearing column, it can be said that Lu Feng has not found anything that can destroy this column so far.

Take the mutant python for example, Xiao Qing's strength is quite strong, and the heavy armored vehicle can be deformed by just one of his tails.

However, even with such attack strength and such force, Xiao Qing could not break one of Lu Feng's load-bearing columns.

It is conceivable how tenacious Lu Feng's road to success is. Lu Feng actually built 15 of these pillars at one time, and the length was also built according to the depth of Lu Feng's excavation. Lu Feng first excavated a height of 40 meters, which can build at least five to six layers of tall underground fortifications.

After these five to six underground floors were built by Lu Feng, they were intended to be used as underground bunkers, so each area basically replicated the structural pattern above the Qingshan base.

Not only does it need to be comfortable and large, but other facilities must also be available. When building, Lu Feng first considered ventilation equipment and escape exits.

Lu Feng built six escape exits alone, and the remaining passages connecting the other two bases are basically set up on each floor.

In this way, not only the smooth passage between each base is greatly connected, but also Lu Feng can reach another base through any route in the fastest time.

Although it will be difficult to manage, it will not be a problem for Lu Feng, because Lu Feng has set up important checkpoints on each floor.

If it is formed in the later stage, these checkpoints will be very important safe exits. Another point is that these passages and exits can quickly run the materials and personnel between each base.

After a passage was blocked by an attack, the two bases could not communicate with each other underground. Lu Feng has a deep understanding of this.

Since he has the current idea, Lu Feng will never let the bases fail to communicate with each other in time due to poor communication.

Mutual support is also a great help, and even if a crisis occurs, the passage with problems can be closed in time, and then pass through other passages.

There are also the power laying and ventilation facilities, vents and power laying on the underground floors one to five under the Qingshan base, as well as the laying of water pipes and communication facilities. These ventilation are all taken into consideration.

It took Lu Feng a long time just to think about these drawings, and someone else was needed to help her complete this work together.

Because this work is indeed a bit difficult for Lu Feng, Lu Feng can build these facilities and install them quickly, but as for how to install the elderly and the weak delicately, he still needs someone to help him.

Of course, the system can also be built directly, but in order to achieve a better humanized construction layout, Lu Feng still has to listen to the suggestions of others, such as Zhou Li and Zheng Xue, as well as Lao He who just joined him, Gu Jiajia, and even Lao Bai. Lu Feng must adopt the suggestions of these people.

Because they will almost live here in the future, if they build according to the layout of these people, it will save a lot of things, even if Lu Feng renovates it later, it will be relatively simple.

And no matter what, women have more ideas about construction, after all, they are much more precise than men's crude ideas.

After all, they are very thoughtful about some details of housekeeping, unlike other people and Lu Feng, whose ideas are very simple.

In short, the underground company under the Qingshan base was built in an orderly manner. However, the excavated stone materials, various soil blocks, and even some rare metal ore materials were completely collected by Lu Feng.

As for the ordinary cement blocks, earth blocks and stones, these materials were all used by Lu Feng to build the fence. Only one side of the fence was almost completely built.

That is the direction facing the center of W, which is the direction that Lu Feng is most concerned about at the moment. However, until Lu Feng completed the construction of this wall, he still did not find any zombie attacks from the center of W.

At this time, Lu Feng also began to become confused, because there was always a steady stream of zombies coming outside his base in that direction.

But since the rainstorm ended, those wildly growing plants appeared, and the zombies in that direction have not appeared again. Lu Feng suspected that the zombies in W city center had not left W city center since the second rainstorm.

So he no longer had the worries he had before, but at this time he began to worry about another direction, because that direction had been ignored by Lu Feng.
