[Not AI-written, an overpowered System, distinct roles, brutal and invincible]
Before the Apocalypse arrives, Zheng Yi obtains a Hatred Points System. The more others hate and envy him, the more unexpected bonus gifts he receives, and the larger his pocket dimension grows. His combat strength rises too.
When the Apocalypse hits, all Zheng Yi has to do is recruit one top-tier beauty to unlock a new superpower. With that advantage, he's unstoppable.
Leading this group, he holds out against bitter cold, zombies, wild beasts, and birds of prey, finally escaping their desperate situation.
Zheng Yi carefully scrapes by, resists, and fights in the Apocalypse, growing stronger all the while until he saves the world.
