Unlimited Upgrades for Apocalyptic Rvs

A cosmic storm kicks off the end of the world. At first, people believed that zombies were mortal bodies after all, and that they could survive under a hail of bullets. Until weird things happened frequently, and physical transcendence became meaningless. Initially, people believed that vaccines for viruses and bacteria would eventually be developed and that strict prevention and control would isolate the pathogens and defeat the plague until the germs passed through the barriers and infected humans regardless of protection. Initially, people thought that the continuous heavy rain was just another Carnian flood event, and that the never-setting sun and eternal night were just manifestations of the earth being locked by the sun's gravity until the earth was submerged and the sky star map disappeared. In the face of emerging disasters, human civilization falls apart, and the glorious past is buried in the black mud... ...
