Female forensic doctor Qin Xuanxuan, using the scalpel as a pen and the autopsy report as evidence, listened to the last silent testimony of the deceased in front of the cold autopsy table. She firmly believes that corpses never lie, and all carefully disguised crimes will be invisible in the face of science and details. Corpses burned on rainy nights, bones in the park, floating corpses on the lake, frozen corpses in cold storage, serial murders of models, massacres in old houses... Ten horrifying crimes and one hundred interlocking chapters on the path to pursue the murderer. Every corpse hides the hidden truth; every autopsy is a head-on confrontation with evil. Faced with layers of puzzles such as perfect alibi, secret room tricks, body dumping after death, and imitated crimes, Qin Xuanxuan relies on her excellent forensic expertise to identify the overlooked fatal clues from the charred remains, old bones, tiny pinholes, trace fibers, and hidden poisons. She not only restores the death process, but also understands human nature through the corpse. Under the lies and disguises, she unearths the greed, jealousy, resentment and paranoia in the murderer's heart. From business grievances and emotional entanglements to the collapse of family relationships and obsession with revenge, behind every case is a complicated and twisted human heart. She solves mysterious cases with her professionalism, examines human nature with her heart, and uses science to uncover the truth, giving voice to the silent dead and making injustice clear. When the scalpel falls, there is no way to hide the evil. She uses corpses as her language and evidence as her sword, adhering to her final respect for life and her eternal obsession with justice.
