I don't know since when, Cheng Yan found that everything around him became different. The silhouettes outside the window on the 22nd floor, the endless corridors, the blood flowing on the walls... Even myself in the mirror will turn into a clock head. Relying on his unique ability to see the past, Cheng Yan repeatedly solves strange cases. Cheng Yan gradually came to know who he was and what the world looked like.
