Dressed as an orphan from the M Dynasty, Jiang Nuo was picked up as a "cousin" by a gambling scholar. After enduring the humiliation for a year, she fled into the rivers and lakes until she was "picked up" by a black carriage on a snowy night.
The man in the car gave her a name and trained her to be a blade. She is his knife, learning the art of autopsy during the day, and enjoying the pleasure of sleeping on the mat at night. She doesn't ask about the origin, and he doesn't care about the past.
Until the news of the "Infinite Cliff" came - that was the starting point of her journey. At this moment, he was taking her to a mysterious case in Lu County: the county magistrate died suddenly in a secret room, with a terrifying smile on his face, and a strange red color in the secret part of his spine.
When modern forensic consciousness collides with ancient mysteries, when the boundary between "tool" and "master" blurs at night, when the alien beast from the star abyss in my arms issues a "scaled man" warning...
Jiang Nuo knew that the first bloody truth in the autopsy record would be revealed by her own hands.
