The lowly maid A Chou was buried alive as a human sacrifice. As she suffocated inside the coffin, memories of her past life awakened: she had been Shen Wangyou, a top forensic pathologist from the 21st century. Digging her fingertips bloody and using a jade hairpin to pry open the coffin, she clawed her way out through darkness and the stench of corpses, bringing modern forensic expertise and reason into a benighted ancient dynasty.
The horrifying birthmark on her face was both a curse and a brand. Pursued by the Shen family, confronted by rumors of the Northern Defender Prince's cruelty, and drawn into a string of bizarre cases in the capital, she was thrust into the heart of a power struggle. She wielded injury analysis like a blade and bloodstain analysis like a stratagem, finding the truth among the dead and laying plans among the living.
The cold-faced, fearsome Northern Defender Prince Xiao Jin, afflicted with a strange poison and widowed by the deaths of three wives, became both her refuge in dire straits and a dangerous ally. An old palace case from fifteen years ago, the secret of the imperial bloodline, and a conspiracy to overthrow the dynasty were gradually laid bare beneath her scalpel.
From a sacrificial offering awaiting slaughter to a powerhouse who controlled the fate of the realm, Shen Wangyou used knowledge to break through traps and justice to define her path. When a forensic eye exposed the dynasty's darkest secrets, she and Xiao Jin would stake their lives on each other, ultimately rewriting their fates and the dynasty's destiny.
