Bai Xi, a top international agent, was betrayed by his partner and organization and died, and his soul passed through the Dayin Prime Minister's Mansion - the legitimate daughter Bai Xi was framed by her concubine Bai Rou'er and her ex-fiancé Xiao Jingyan for a "virtuous elopement", and eventually drowned in an "accident". At the moment of rebirth, the [Ultimate Counterattack System] was bound, and the fire of revenge was rekindled in her eyes: In this life, the perpetrators must pay for their sins!
Relying on the modern knowledge (toxicology, criminal investigation, management) and secret agent instincts exchanged by the system, she started by conditioning her body, tearing apart the slaves who were bullied in the house, and turned Bai Rouer's "well-intentioned temptation" into a sharp blade. She exposed the conspiracy with "toxicological analysis" at the banquet of the Hou Mansion, and she first showed her talents. He opened Xiguang Pavilion and secretly built an intelligence network under the cover of a "beauty store"; he used medical improvements to save lives and accumulate reputation; he also integrated agent stealth and anti-reconnaissance skills into ancient times, turning his opponents' plans into digging their own graves.
The reclusive King Mo Yechenyuan noticed her because of her "untimely" sharpness. This emperor's uncle, who wears a silver mask and holds a large number of troops, appears to be cold and aggressive on the surface, but in reality he has far-reaching plans. The two went from "mutual testing" to "interest cooperation": he helped her find out the truth about the original owner's drowning, and she trained a "special force" for him; in the court, they joined forces to overthrow Jamel Xiao's military power layout; in the rivers and lakes, they jointly strangled the remnants of the Blood Lotus Sect... In life and death, Ye Chenyuan's possessiveness and Bai Xi's trust grew at the same time, but they were pulled into each other by their respective secrets ((his life experience, her past life shadow)).
