Man of the clouds
The Doomsday War thousands of years ago destroyed human civilization and destroyed the surface ecology, and human beings could only live in shelters on the cliffs to continue the fire of civilization.
However, over the past thousand years, humans on the cliff have gradually developed a new way of living and social model, and people have gradually migrated to the sky using pre-apocalyptic technology, and installed their homes on highly toxic clouds full of radiation.
These people who sail on floats above the sea of clouds, they call themselves the people of the clouds.
