Bizarre and violent deaths of seal officials occurred one after another in Bianjing City. The circumstances of death were different, and no traces were left at the scene. Only a strange "ink mark" on the body of the deceased mocked the incompetence of Dali Temple like a ghost.
Just when everyone thought these were just a few ordinary accidental deaths, a woman named Ling Chuyun, holding a scalpel, knocked on the door of Dali Temple.
In her eyes, the corpse is a silent witness. Every scar and every inch of corpse hides a secret code leading to the truth.
Pei Yan, the young minister of Dali Temple, valued rules the most in his life, and hated strange powers and chaos the most. He looked at this deviant woman in front of him, cutting open the corpse of an official, speaking freely, and he felt that the entire dynasty was shaken by her.
He wanted to throw her into prison, but found that where her blade was pointing was an abyss that he could not reach with the legal provisions.
When the undercurrent of the court surges, when the shadow of the old and new party strife shrouds the whole city, when the serial murders point to a shocking conspiracy called "Mogui"...
He is a defender of rules.
She is a rule breaker.
They had to make a contract, use the blade and the law as swords, and pursue the only light together in this foggy Bianjing city.
"Pei Shaoqing, are your rules still enough?"
"... Miss Ling, I will lend you my sword for a while."
Purpose: Taking the scenery of the Song Dynasty as a scroll, it depicts an independent picture of how a group of women with special skills relied on their own wisdom and expertise to solve strange cases, protect morality, and finally define and realize their own self-worth amidst the constraints of the times and the scrutiny of men.
