History is not a one-way train, but a crime scene buried in layers. Under every page of "normal" narrative, there may be hidden grievances that have never been redressed, heresies that have been deliberately obliterated, and the painful struggle of civilization at a fork in the road.
Detective Chen Jian died in a mission and woke up in a "time shuttle" that transcended time. He was told that his new mission was to dive into the long river of history and uncover those "abnormal points" obscured by the dust of time - those strange mysteries that are not recorded in official history and are tabooed in unofficial history.
From the craftsmen of the Qin Dynasty who were sealed alive into figurines, to the everlasting will-o'-the-wisps under the water during the Battle of Red Cliff; from the hundreds of people who disappeared in "Along the River During the Qingming Festival", to the shadow caves that predict the future in Dunhuang murals... Chen Jian uses the sharp edge of modern criminal investigation to cut through the skin of history. He has seen the unyieldingness of little people, witnessed the helplessness of falling in love and killing each other, and even touched the cold and huge weight of systems and times when they run over individuals.
However, when the truth peeled off like layers of bronze rust, Chen Jian was shocked to discover that all the cases pointed to a deeper mystery. The origin of the shuttle, the truth about his own "resurrection", and the mysterious woman Mo Yu who has been silently observing him throughout the dynasties... The police badge in his hand is not rusty, but it reflects the reflection of himself in a closed loop of history.
