Su Nuo, a concubine-born daughter of the Marquis's household, has the mind of a seven-year-old, but possesses the fierce instincts of an agent, etched into her very bones. At the Peach Blossom Banquet, she clings to Xiao Jinyuan, the Regent who holds power over the court, and the whole city mocks her as a lovesick fool. Xiao Jinyuan has suffered for seven years from the deadly Cold Bone Ash poison. At first, he is full of contempt for her, yet time and again, the innocent Su Nuo unconsciously neutralizes its lethal effects.
Rumors sweep through the court, and one conspiracy after another unfolds. Her legitimate elder sister and corrupt officials repeatedly lay traps to harm them both. During an ambush in a mountain valley, Su Nuo is gravely wounded while saving Xiao Jinyuan. The chains binding her mind shatter, and the memories and brilliance of a top agent awaken completely.
The once foolish girl becomes a formidable force, while Xiao Jinyuan, already consumed by love, casts aside his aloof bearing and turns around to pursue her. Together, they clear away the layers of intrigue at court, settle old poison plots and foreign threats, and break through the constraints of convention, surviving death's door to build a flourishing life together.
It feels pretty good. The heroine in the end must be an all-around talent. I hope she won't be a sadist.
