Chapter 278: Underground world

After several months of construction under Marin Town, almost all of Marin Town was hollowed out.
A hundred meters underground, a huge world is gradually improving.
On the top, the top layer of super alloy, fixed this huge underground space.
On both sides, there are also reinforcement devices of super alloy structure, even if it is the main gun of the tank, it is difficult to leave an obvious pothole.
According to the data provided by the base, there is a special cement layer up to fifty meters thick on the top of the alloy with a thickness of five meters. Between the cement layer and the superalloy, there are also several radiation-proof interlayers.
Cai Ruichen, who entered the underground world for the first time, just naively thought that the underground construction mode of the red police unit was to build an underground space to house the building units.
However, when he understood these structures, he understood why the minimum depth of 100 meters from the ground is required.
That's because the underground space created by the base not only has an extremely strong load-bearing capacity, but also has a special cement layer to avoid any detection equipment, and a radiation-proof isolation layer to resist various radiation.
Such a structure has exceeded the standard for building a nuclear bomb silo.
The fixed nuclear bomb silo, due to its fixed location and unable to move, can easily become the first wave of attack targets when a nuclear war breaks out.
In order to ensure that the silo can withstand nuclear strikes, each nuclear bomb silo is not only built to be extremely strong, but even all can withstand the harm of nuclear radiation to the people below.
Therefore, the construction of nuclear bomb silos is actually very complicated, and the cost of construction is also very expensive.
And the underground construction mode of the base construction, its defensive ability also exceeds the construction target of nuclear bomb silos.
Using the defense data given by the base, even if it is an aerospace kinetic energy weapon, it may not necessarily penetrate this layer of defense.
Of course, such an uncertain expression is because the mass of aerospace kinetic energy weapons determines the destructive power.
If you encounter more than a ton of tungsten rods, let alone such a defense. Even add a level of defense. It is also difficult to resist.
The energy destroyed by its kinetic energy has reached the level of a medium-sized meteorite.
Therefore, if you really encounter a space-based weapon like the Battle of God, then this layer of defense will simply not be able to resist it.
but. If it resists conventional weapons on the ground, or just small kinetic energy weapons in low earth orbit. There is still a certain degree of defense.
In addition, even any penetration bomb in the world cannot threaten it.
Currently. The underground world built on the base is already the size of Marin Town. And the scope is constantly expanding.
The first underground world in the future will cover an area of ​​more than 100 square kilometers, a veritable underground super industrial city.
This is only the first stage. The second stage will continue down, from 100 meters underground to 500 meters underground. At that time, all will be used and divided into layers of underground space.
Cai Ruichen's plan is that in the next fifteen years. This will become a super underground kingdom that can accommodate at least 50 million people.
However, it is hard to say whether such a place will be opened. It is not a delusion to complete such crazy construction work.
Coming to this underground space again, it has expanded to a world almost twenty square kilometers in size.
The augmented reality technology is completely adopted above the head, plus the light rays that mimic the sun's ultraviolet rays, so there is not much difference between here and outside.
The town of Marin, not far from Lake Celsar, has good groundwater resources below.
Good groundwater resources can be used very well. Two simulated rivers are under construction in the underground space and will come to the next level, and there will be simulated waterfalls.
After the construction is completed, it is expected to be connected to the underground space built by the No. 1 technology expansion station far in the Arabian desert.
Under Qiu Mingxu's design, this huge underground world will no longer be a purely underground industrial kingdom in the future.
At present, flowers and trees have been planted in this space, with central air conditioning and integrated air purification systems, the comfort of the underground world will reach a level that is very suitable for human living.
It will even be better than the ground, which has been heavily polluted, and a complete ecological cycle system will be reconstructed in the underground world.
Moreover, everything here is completely enclosed from the outside, and when necessary in the future, people who come in can also be strictly controlled.
Although this underground world is not even a rudimentary form, Cai Ruichen often comes in to take a look.
At present, the largest number in the underground world is the industrial cluster, a set of various production lines, neatly arranged in the underground space.
Around him, various machine butlers are cleaning the underground space that has expanded today.
Cai Ruichen, who entered the underground space, walked straight to the nearest row of 3D printers.
Although these 3D printers are exactly the same as the 3D molding equipment in the tank factory, these are not equipment of the tank factory's production line, but are all equipment factories.
The tank factory produces red police weapons, and the equipment factory produces those civilian or dual-use engineering vehicles or other vehicles. There is also a junior arsenal on the side, which is used to produce weapons and ammunition.
These three production lines are now the main body of this underground world and the backing for all the development of the Red Police Corps.
Among the equipment factories, all kinds of trucks are currently being produced at full speed, with the largest number of heavy trucks.
The various truck parts formed by 3D laser plastic molding were all sent to the assembly factory on the ground as soon as possible, which is the factory image interviewed by the outside world.
Separating the production line from the core 3D laser plastic molding is naturally for confidentiality.
Cai Ruichen intends to open some factory production lines, just for the necessary publicity, to tell the world that the advanced robot production line owned by the future technology group ~ EbookFREE.me ~ Of course, it is not to show everything.
At least the reporters saw only those parts that were assembled into trucks on the production line.
The true core technology cannot be opened to the outside world.
Therefore, many people are now speculating about where the industrial raw materials of the future technology group are obtained.
After all, the production of any product is closely related to raw materials.
However, none of the raw material suppliers in the world have any cooperation with Future Technology Group.
If the Future Technology Group has its own raw material processing system, what about the elements used to produce materials?
These can't be changed out of thin air.
It's just for such external curiosity, it is impossible for Future Technology Group to give an explanation.
Maybe one day, when the ore refinery is not a secret, the answer will really appear. (To be continued.) Enable new URL
