Zhaoyang County Princess Ye Qiong is struck by a donkey, her soul time-travels, and she binds to a life-extension system. With only ten-odd days of mortal life left, she can only extend her life by completing missions. After losing her memory, her disposition changes drastically; imitating her profligate father Prince Duan, she barges into Chunfeng Tower and impersonates her father's name to save people, successively ruining Prince Duan's reputation. Father and daughter quarrel endlessly, stirring the imperial palace into chaos. The Emperor specially establishes the Capital City Patrol Office, ordering the two of them to serve as city patrol envoys. Taking office empty-handed, Ye Qiong guards against the Gu family's scheming and the reborn Gu Qingyu's conspiracy on one hand, while starting a business to make money on the other, engaging in a love-hate dynamic with her comical father. Relying on her eccentric and whimsical mind to defuse wave after wave of crisis, she seeks survival in a hilarious farce and reverses the destiny of herself and Prince Duan's estate.
