Female Torturer on the Run

The most prominent family in the Tianyao Dynasty was the one that had been in charge of punishment for six hundred years.

She changed from an unattainable female torturer of Famen to a self-destructive person, which caused her father, the torturer of Famen, a headache. After another confrontation between father and daughter, the eldest lady escaped from the law and stepped into a bloody world where there is no justice and only the strong and the weak. How can the powerless young lady establish fair laws in the world, and how can she dismantle the Qianjimen, the largest sect in the world that uses violence to fight violence?
