The Rift Era: I Grow Stronger from a Tiny Recycling Center

[Apocalypse] [Relentless from start to finish] [High Martial Arts] [Survival] [Absorb Energy to Increase Cultivation]

Two hundred years after the apocalypse, humanity has been reduced to Hope City and five satellite cities in the Dragon Nation. Mutant beasts roam outside the walls, while life inside is harsh and desperate. Lin Yue arrives in the slums at the very bottom of Hope City...

He starts out a little weak and has to fight his way up from the bottom. A satisfying power-up story.
