The Detective's Mission: Unraveling the Mystery of Death tells the story of Zhou Can, a "consulting detective" drawn into a series of bizarre murders. A headless corpse at a clock factory, a locked-room death in a library, a poisoning at a theater... Bloody gears and cryptic notes are always left beside the victims, and the precise methods resemble a cruel game against time.
As his investigation deepens, Zhou Can discovers that all the victims were connected to the "Time Project" from three years ago, a deranged experiment centered on memory transplants and human modification. And he himself is not merely the investigator: he is also the experiment's "Vessel 013." His father's pocket watch, the identity of the mysterious woman "Xiao Ya," the secret of the violet-eyed gene... Layer upon layer of mystery binds him tightly to the past.
Amid the sound of turning gears lies an obsession with revenge, along with a glimmer of redemption. When memory and reality intertwine and the killer's blade turns toward him, Zhou Can finally understands: the most terrifying abyss is not the case itself, but the rust that human nature has etched into time.
This is a race against time, and a struggle against himself. In the gaps between meshing gears, he must recover his altered memories and uncover the ultimate truth behind all the deaths: a truth about love and sin.
