The blood moon rises, and the supernatural descends.
My roommate's head is bitten off by a mouth that appears out of nowhere right before my eyes, but in my moment of desperation, I unlock the 【Slaughter System】.
Ding! Kill a common supernatural creature and gain 50 Slaughter Points!
Ding! Kill an elite supernatural creature and unlock the skill 【Eye of Slaughter】!
Ding! Trigger a hundred-kill streak and earn the S-rank skill 【Slaughter Domain】!
While everyone else struggles to survive the apocalypse, I carve a path through every haunted domain.
The hospital in the mirror, the blood moon school, the midnight bus: every haunted domain is my hunting ground.
Then I meet a woman named Su Muxue. She tells me my System isn't a cheat, but a key.
Behind the supernatural invasion lies a conspiracy on a dimensional scale.
And my existence was designed from the very beginning.
