Hilarious and Satisfying Story of Battling a Wicked Woman from Nine to Five

Su Yu Yan, a special agent from the twenty-sixth century, dies during a mission and transmigrates into the body of a woman who shares her name in the Dafeng Dynasty. The original host was the legitimate daughter of General Su Lin, switched at birth and raised in poverty for sixteen years before being brought back to the General's Manor six months prior. Upon her return, she faced immediate hostility from the fake heiress, Su Yao, who had lived as the cherished daughter of the household for over a decade. Su Yao, driven by possessive jealousy and fear of losing her status, orchestrated a scheme to ruin Su Yu Yan's reputation. During the Empress's birthday banquet at Qingyi Garden, Su Yao drugged Su Yu Yan with a potent love potion and arranged for a man to assault her in a secluded chamber. However, the original host's heart could not withstand the poison, and she died just as Su Yu Yan's soul entered her body.

Awakening in the side chamber, Su Yu Yan encounters the assigned attacker, a square-faced imperial guard. Displaying her combat skills, she incapacitates him with scissors and a stool, leaving him alive as a witness. She discovers she is also suffering from the love drug and realizes she must find a suitable partner to survive the night. Her search leads her to Prince Rui, the second prince and a renowned military commander known as the God of War. Prince Rui is also poisoned and near death. Su Yu Yan forcibly subdues him using a tendon-weakening powder and an aphrodisiac, compelling him to serve as her antidote in exchange for a cure he desperately needs. After the act, she provides him with the antidote to his poison and leaves gold jewelry as compensation, displaying a shameless and pragmatic attitude that infuriates the prince.

The situation escalates when the Crown Prince and a crowd of onlookers burst into the chamber, discovering Su Yu Yan with Prince Rui. Su Yao, feigning shock and moral outrage, attempts to publicly humiliate Su Yu Yan and destroy her remaining chances of marriage. Prince Rui, enraged by the humiliation and the loss of his dignity, coldly declares that he will not marry Su Yu Yan and that their engagement to the Crown Prince is void due to her actions. He reveals that the plot was a joint effort between Su Yao and the Crown Princess, who sought to ruin Su Yu Yan's virtue. Su Yu Yan, however, remains composed and manipulates the situation to her advantage. She feigns mental instability and plays the victim, convincing Prince Rui to help her punish Su Yao by framing her for the crimes.

Back at the General's Manor, Su Yu Yan continues her counterattacks. During the Old Madam's birthday banquet, she exposes Su Yao's theft of a treasured jade bracelet, which Su Yao had planted in Su Yu Yan's room to frame her previously. Su Yu Yan orchestrates a search that reveals the bracelet in Su Yao's quarters, along with evidence of her complicity. Simultaneously, the poison Su Yu Yan administered to Su Yao earlier begins to take effect, causing her to suffer from uncontrollable gluttony and vomiting during the banquet, further humiliating her in front of the family. Su Yu Yan aligns herself with her biological mother, Madam Du, and her eldest brother, Su Zhan, a cavalry general, while distancing herself from the second son, Su Zhe, who remains biased toward Su Yao. The story concludes with Su Yu Yan firmly establishing her position within the family and setting her sights on dismantling the influence of the fake heiress and her conspirators in the imperial court.
