Shen Yan, once the calmest mechanic on the edge of the city, is now repairing the mechanical heart of an unknown corpse in an abandoned factory at midnight. His clumsy craftsmanship can regenerate steel, but he cannot piece together his fragmented past. The night was dark, strange whispers came from the depths of the factory, and the metal parts seemed to carry bloody memories. Shen Yan accidentally awakens a self-aware mechanical ghost. It interweaves temptation and threat with its soft voice, and proposes a deal that cannot be refused - using his love in exchange for the forgotten truth.
When death and machinery intertwined, Shen Yan walked step by step in the maze of love and fear. He longs to escape from the shadows of the past, but cannot resist the mysterious attraction of ghosts. The boundary between machinery and soul is blurred in the terrifying fog. Shen Yan must decide whether to become a craftsman who controls destiny, or a lover swallowed by darkness. Every loose screw is a precursor to the collapse of reality; every heartbeat may be the prelude to a nightmare. This is an adventure about redemption and destruction, as well as a chilling ode to love and death.
