Modern corporate slave Ye Qiong transmigrates to become Prince Duan's Mansion's Princess Zhaoyang. After binding with the "Villain System", she only has 15 days of lifespan left, and must rely on causing trouble and raising popularity to extend her life. She first wields a kitchen knife to chase and hack her prodigal old dad Prince Duan, seizing financial control, then buys a brothel and remakes it into the "Chunfeng Tower" theater to make money, and even extorts the official post of Kyoto Inspector from the emperor. The father and daughter are forcibly thrown into the Marquis of Dingyuan treason case, stumbling all the way—walking prisoners on the street, investigating the Ministry of Punishments at night, and surrounding the restaurant, unexpectedly unearthing the true culprit, the Third Prince. In the end, Ye Qiong clears her grievances, gains a hundred years of lifespan, and takes Prince Duan and the little imperial grandson to continue "making trouble" in the capital.
