A top-tier corporate workaholic and artist in modern times, Xun Zhen, transmigrates through souls into the Song dynasty harem, becoming an unranked and grade-less imperial attendant and imperial concubine reserve. To survive, she signs an agreement with the Bian Que medical system, guaranteeing her survival in the court for forty years. The system ensures she stays healthy and sober; the longer she lives, the more rewards she gets, and if she doesn't live long enough, everything is over. Bearing this mentally disabled system, she treats harem struggles like a workplace, and promotion as a career climb, advancing all the way from an imperial attendant and noble lady to a beauty, targeting the main seat directly. Facing the sarcastic remarks of Noble Lady Han and the arrogant and tyrannical behavior of Consort Qiao, she plays along obediently while remaining sober and pragmatic, unaware that the young emperor who casually summons her to attend his bed has long since kept her every move in his sights.
