Lin Wan, the chief medical examiner of the modern era, opened her eyes and transformed into a cannon-fodder concubine in an ancient house fight. She was forced to marry Xie Jingxing, the eldest son of the Marquis of Jing'an Mansion, who was rumored to be sick and dying in her eldest sister's stead.
On her wedding night, she was caught in a poisoning crisis, and unexpectedly discovered that the frail prince was actually a powerful official secretly in charge of the prison and investigating old cases. In order to survive, Lin Wan used her modern forensic skills as a bargaining chip to reach a cooperation with Xie Jingxing: she relied on corpse language to find the truth, and he used his authority to protect her.
From an alliance of interests that test each other, to a soul mate who depends on each other for life and death. The two work together to investigate a series of strange cases, uncover secrets in the house, stir up the chaos in the court, and gradually uncover the massacre of the family seventeen years ago and the shocking conspiracy of the royal family.
Meeting in the endless darkness, they are each other's only light. She healed him of his years of pain with professionalism, and he protected her with affection and fearlessness throughout his life.
Purpose: Revenge and redemption coexist, personal growth and protection of family and country are sublimated.
