Jiang Zhao, who has a doctorate in modern archeology and medicine, was transformed into the legitimate daughter of the Duke of Zhaohua Town. Under the prosperity of rituals and music, aristocratic families were in power, medicine was monopolized by the nobles, and no one cared about the sufferings of the people. She hides her clumsiness in a boudoir, but she actually possesses the power of "sympathy between life and death" - when she touches an injured person, she will see the afterimage of their memory. Poison was hidden in the pottery figurines buried with him, his grandmother was mysteriously poisoned, and the family tried to hide it. Jiang Zhao used sympathy to reveal the truth, but was suppressed and silenced. His mother sent a secret message asking for help, and he was urgently summoned to the Imperial Hospital by imperial edict. The gears of his fate suddenly turned.
When he first met the regent Xiao Jingheng, he looked at him coldly; when he rescued General Xie Yunci again, his armor was stained with blood. She established herself with medical skills, broke through with her supernatural powers, and was involved in the turbulent undercurrents of the court.
The three of them investigate the murder case together, and each step is shocking. Is she a pawn of the imperial power or the world's doctor? Sweet with a knife, cruel but not a dog, a legend about freedom and mountains and rivers has begun.
