In her past life, Sheng Qingluan, the sixth princess of Great Dajing, was murdered by the step-empress and her younger sister, dying with bitter resentment. Reborn with grievance, she tears off her disguise and proceeds step by step: protecting her elder brother, slaying enemies, and breaking puzzles. The hypocritical step-empress, the vicious eleventh sister, and the dowager and noble imperial concubine each harboring their own schemes—she accepts them all with a smile and settles accounts one by one. Pei Yan, the Secretariat Director wielding power over the court, and Lu Shizheng, the youthful general, both become the knives and blades in her hands. In this lifetime, she will personally send everyone to hell.
