The apocalypse arrives, and I bind myself to a Doomsday Survival System. Growing stronger is the only rule!
While others struggle to survive in the jaws of zombies, I see the zombie hordes as mobile experience packs.
While they crack each other's skulls over a single biscuit, I wield divine weapons and treat mutated zombie kings as prey in the palm of my hand.
The campus beauty and senior who once treated me like an insect?
Now she's my exclusive “supply.” She hates me to the bone, but can only tremble and beg for her life in my arms. Watching humiliation and fear fill her proud eyes is more fun than crushing a hundred zombies!
Order has collapsed, and humanity is gone? Perfect! This is the paradise I've been longing for!
I'll walk across mountains of corpses and seas of blood, and personally place the most dazzling collars on my goddesses... Then I'll build an apocalyptic empire of my own!
