Spiritual qi has returned to Blue Star, and national-destiny rule-based horror games have arrived. Selected participants around the world draw lots to determine their fate, with talents ranging from F to SSS rank.
Su Bai's talent is a foregone conclusion: F-minus rank (Blue Star's assessment: mental contamination, completely useless).
But no one knows that this boy, fresh out of a mental hospital, has three "selves" locked inside him.
The first personality is a calm, rational detective who can spot loopholes in any eerie rule.
The second is a bloodthirsty, violent demon slayer who tears ancient gods apart with his bare hands as easily as chopping vegetables.
The third is an upright exorcist priest whose talismans drive away every evil spirit.
A good-for-nothing in the eyes of Blue Star's people, he is the nightmare of the uncanny world.
Legend has it that even the uncanny give him a wide berth, honoring him as the "reincarnated Lord of Slaughter."
Years later, as uncanny disasters rage, the survivors of Dragon Nation on Blue Star are driven to the brink.
The trembling broadcast from the authorities announces: "Hurry! Take shelter in that Seventh District Mental Hospital! It's the only way to survive!"
Su Bai sits on his throne, looking at his frightened countrymen outside the door. A faint smile touches his lips. "Long time no see, folks."
"This time, I'll guard the human world."
