Apocalypse: On the Island Nation, I Kill and Kill and Kill

[Multiple heroines] + [no goody-two-shoes protagonist] + [decisive and ruthless] + [Apocalypse] + [System] + [scheming]

Stranded on an island nation, Qi Bai faces the collapse of civilization as the apocalypse arrives.

At this critical moment, he activates the God of Slaughter System. Every life he takes earns him Kill Points and makes him stronger.

In a world where weakness is a sin and the strong rule, strength is everything.

Qi Bai slaughters monsters, zombies, and all manner of beings until he becomes the strongest and sole ruler of this land.

[People of the island nation, it's time to pay for the sins you've committed.]

[Those who follow me will prosper; those who oppose me will perish!]
