Lin Xiao, a modern detective, accidentally passed through the book and became the cannon fodder substitute Su Wan in the period novel who could not survive more than three months. Bound to the paranoid villain Lu Chenzhou, she disguised herself as Bai Yueguang's stand-in and used her criminal investigation skills to dig for survival chips. From hospital clues to night visits to abandoned clinics, from cemetery traps to contract games, she works step by step, not only to escape the death ending of the original work, but also to uncover the truth behind Bai Yueguang and Shen Yueru's disappearance. And the seemingly cold-hearted Lu Chenzhou is actually closely related to the dusty and unsolved case. In the fog of the times and the temptation of human nature, the two people went from being wary of each other to containing each other, and a strong pull between the substitute and the real murderer, investigation and survival began.
