She was originally a modern forensic doctor and a doctor of traditional Chinese medicine. Once she traveled through time, she became Xuanqing, an amnesiac Taoist nun from the Sanqing Temple of the Great Zhou Dynasty.
His memory is sealed and his life experience is a mystery. Only the skills of Taoist medicine are engraved in his bones. She uses "watching qi" to judge life and death, uses "talisman needles" to drive away evil spirits, and "refines elixirs" to resolve strange poisons - every time she solves a case, she awakens a layer of green power and recovers a piece of the forgotten past.
Eight major cases, eight sad people who couldn't love each other.
The cry of the baby in the coffin hides the life-and-death promise between the maid and the concubine across the family line; the seventeen marks of strangulation in the case of the headless corpse in the Ministry of Punishment are engraved with the desperate decision of the palace maid and the guards to kill for protection; the Jiangnan watercraft disappeared out of thin air, obliterating the ten-year wait for the governor's daughter The deep love; the night when the ghost in the Gongyuan knocked on the door, the old Confucian scholar spent his life to atone for the one he missed; the soldier who defrauded the corpse at the border guarded a dilemma of love in troubled times; when the plague spread in the capital, the humblest little eunuch paid back the only warmth with his life...
She has gone through all the joys and sorrows in the world, but she doesn't know that the greatest tragedy is right next to her.
The master who had raised her for twenty years was an accomplice in killing her whole family. The person who loved her the most was also the person who hurt her the most.
When the eight cases were brought back to the family and her memories were revived, she stood at the center of the whirlpool of the court's struggle for heirs, facing the truth and betrayal, family, country and personal relationships - hatred or forgiveness? Let it go or settle it?
