Jingzhou, a city shrouded in thick fog from the Yangtze River. Lu Chenzhou, head of the Municipal Public Security Bureau’s Cold Case Reopening Unit, possesses a rare ability called “Final Moments Perception”: he can read the sensory memories of the dead’s last 60 seconds. But this ability is no gift. It is a curse born of the “Black Box Experiment” at a steel mill in 1998.
That secret experiment implanted the memories of the dead into the living, creating an unpayable “time debt.” Every debt must be passed down from generation to generation through the “Seventh Terminal.” When bodies begin appearing in cases that imitate the legend of the “Ferryman in the Fog,” Lu Chenzhou discovers that every victim is repaying the same chain of debt, and the person ultimately responsible is none other than himself.
Worse still, his deceased daughter, Wanxing, was one of the 1998 test subjects. The debt will never end; it will only be passed on. On July 23, 2024, the day Lu Chenzhou turns 35, he must choose: pass 28 memory debts on to his daughter, or let the city become a living black box.
