The post-apocalyptic girl Ye Qiong traveled through time and became the princess of Zhaoyang. She was bound to an amnesia system and kept getting into trouble in order to earn a living. She bought a brothel, rescued runaway slaves, and quarreled with the prince. After being appointed as the inspector of Kyoto by the emperor, she became even more out of control. Ye Qiong takes the "prodigal father" Duan Wang and a group of partners to outsmart the British duke, rescue the Marquis of Dingyuan, open a theater, reorganize the capital, and repeatedly solve strange cases amidst laughter and crisis. Ye Qiong relies on modern thinking and system plug-ins to clean up the court, protect family ties while laughing and scolding, and live a free and unrestrained life as a princess.
