A doomsday epic about betrayal and rebirth On the ground: the death zone completely swallowed by the "city-eating vine" Plants evolve at a far supernormal speed, and steel and concrete become their nutrients If humans survive on the surface for no more than 72 hours, they will gradually "vegetate" But here is the last sunshine, starry sky and freedom of the old world Underground: The "Ant Nest" Society of Human Survivors Strict hierarchy, allocating oxygen and space according to contribution Adhering to absolute pragmatism, emotions are regarded as a "waste of oxygen" Supreme Law Article: "Anyone who brings plants underground shall be punished for treason against humanity."
