Under the neon lights of the midnight city, one after another strange murders are swallowing up the truth like an abyss. My name is Lin Mo, a bailiff who hides secrets and is accustomed to using cold logic to cut through layers of fog. When "City Hunter" Lu Chenyuan broke into my detective world with his romance and mystery, this cat-and-mouse game with life as the bet was destined to be full of thorns.
Blood-stained nursery rhymes, disappearing evidence, the mask of a hypocrite... Behind the serial murders is a revenge chess game that spans ten years. We are both comrades fighting side by side and opponents testing each other. The game of dual identities is undercurrent at the stroke of every midnight. When I found the coin engraved with a special symbol at the crime scene, I finally realized that I had been involved in a whirlpool darker than the murder - and the man beside me, who always provided warmth in crisis situations, hid a secret that could subvert everything.
The abyss stares at us, and we must find the glimmer of hope for a comeback in the gap between truth and humanity.
