Notes Written by a Female Widow from Bianjing

Gu Banxia, ​​the daughter of a widower from Bianjing, has not turned over the car in ten years of post-mortem examination, but her father's prescription "Aconitum Three Coins" has been turned over for twenty years. Yun Luo died in front of the dressing table, with two strangulation marks on his neck; his grandmother was tied up in exchange for half a yellowing pulse record; the man in gray clothes was hidden in the old archives of the Imperial Medical Bureau, with a medium build and a scar on his left eyebrow bone. She thought she was investigating a medical accident that occurred twenty years ago, but she found out at the end—— The man her father saved with his life back then was a prince who should not be alive in the palace. And the man in gray has been looking for him for nineteen years.
