Du Gu Wu, the formidable Duke Jiu Qiansui, finds himself bound in matrimony to Feng Bailin, a woman the empire deems unworthy—dismissed as plain, incompetent, and cursed by misfortune. Yet she alone shows no dread of his notorious reputation as a wife-killer and eunuch, brazenly accepting his hollow title while bearing his children without hesitation. The court erupts in scandal. Dismissing her as worthless and uninspiring, Du Gu Wu vows to end the marriage within a year. When that fateful moment arrives, he reserves the grandest establishment in all the land to celebrate their separation, only to discover the proprietor grants three complimentary days in honor of the occasion. As the renowned beauty who commands the attention of heroes across the realm takes her leave, she utters a cutting remark: "You assume I desired your flesh—I merely sought your throne's blessing." Following the divorce, Feng Bailin's true power emerges. When pestilence ravages the empire, a miraculous healer appears—none other than Feng Bailin herself. As famine consumes the provinces, the kingdom's wealthiest magnate mobilizes relief efforts, revealed to be Feng Bailin once more. When nine united dynasties lay siege to the walls and salvation seems impossible, ten thousand wild creatures rise to defend them, orchestrated by Feng Bailin. Across months of relentless pursuit through distant lands, Du Gu Wu desperately trails his estranged wife: "Ancestor, grant me another chance to wed you." Their two children respond in perfect harmony: "Father King, you must take your place at the back of the line!"
