When he woke up, Chen Mo, the all-powerful criminal police captain, turned out to be Chen Weiguo, an unknown technician at the steel plant in 1974. He wanted to survive in a low profile, but he was accidentally involved in the murder of a model worker's wife who died tragically in an air-raid shelter. An old blood-stained newspaper at the scene recorded the details of three unsolved cases - surprisingly consistent with the "Western Suburbs Serial Cases" that he failed to solve despite all his efforts in his previous life!
During the investigation, it was discovered that the model worker himself died in a mysterious "accident". Chen Mo pieced together a complete report from the dusty newspapers in the archives, but it was like falling into an ice cave: in the blank space of the report, six names were handwritten - the first five were the deceased in the unsolved case, and the sixth was "Chen Weiguo"! The date of death was just three days later.
72 Hours countdown to death! The murderer not only knew his identity, but also seemed like a ghost that spanned time and space, using imported candies as a symbol, approaching him step by step. The truth about time travel, the connection between serial murders, and the origin of the mysterious list... In the thick of fog, Chen Mo discovered that what he was tracking was not only a cold-blooded killer from the 1970s, but also a cold project called "The Seam of Time," a terrifying existence from the future that manipulated life and death and intended to completely "sew" him out of time and space.
From the blood in the air-raid shelter to the heartbeat of the boiler room; from the dust in the archives to the roar of the steel rolling workshop... Chen Weiguo must struggle to survive in the cracks of the times. Surrounded by the invisible "postman" and the deadly "tailor", he tears apart the camouflage of time and space and faces the sharp blade from the future hanging above his head.
In three days, can he reverse the death list and uncover the shocking truth that spans fifty years?
