Doomsday: My Shelter Can Be Upgraded Indefinitely

Volcano eruption, earthquake, hurricane, hail, tsunami, meteorite fall, violent storm snow, and plummeting temperature.
There were all kinds of bad weather here as you could imagine.
How could a shabby house survive in the apocalypse?
First, there was a generator, then a distiller.
The airplane, armored car, steel armor, I had everything here.
The level of the shelter and the defensive ability was improved level by level.
What? Were you still eating soil? I had already eaten big fish and meat.
Did you still live in a dilapidated house with leaks on all sides? I had already lived in the big villa!
Was it difficult to survive in the apocalypse? Why didn't I feel it?
