"Air-raid shelter" and "Bunker" have existed since the beginning of human war.
Now it is not difficult to find those ruins or have been settled by the poor.
During World War II, all houses and apartments in Germany had basements to protect them from air raids.
Later, more and more underground buildings were built, such as subway stations, tunnels, underground shopping malls, etc., which can also be used as bomb shelters.
More renovated old bunkers called "Doomsday Bunker" were bid by the rich. It is said to be able to withstand earthquakes with a magnitude of 10 on the Richter scale, strong winds of 700 kilometers per hour, 36 meters of snow and 3,000 millimeters of rainfall. Even if it is soaked in floods for more than 500 hours, the ground will burn with a fire of 677 ℃, and nuclear explosions and solar flares will occur outside. When the outbreak occurs, everyone in the bunker will be safe.
There have been records in the past. As early as Hiroshima, Japan was bombed by an atomic bomb, an ordinary resident was in the central area of the bombing. He only survived the bombing by hiding in a basement only two meters above the ground.
The dove house I live in is 5 meters underground, which is considered a safer location than that of the Hiroshima resident.
In fact, it is a small, medium and high-rise unit in the residential complex of the bunker city.
My house also has a window view, but it is all concrete and steel bars.
If you want to see the beautiful scenery, you can only rely on smart projection to change the window scene.
All you see is what the earth once had in the past and what it now does not have.
The temperature in the bunker is a constant 25 degrees.
If you want to change your indoor temperature, you need to apply to the management office separately.
Although the electricity bill is paid by the user, the government will take precautions in order to save electricity.
Always, no one will know...
Most of the renewable energy we use now comes from that fiery sun that can no longer be faced directly...
Will it disappear one day...
