Chu Huaijin, the eldest princess of the Ministry of Industry of the Yong Dynasty, once traveled through time and became Chu Xiaojin, a cleaning girl who was in huge debts and allowed to be bullied in the modern city. Faced with the humiliation of "unruly people" and sky-high debts, she applied the wisdom of the palace to the modern business world - formulating ancient detergents, creating healthy tea drinks, developing national fashion cosmetics, and creating cultural IP. She accidentally stepped on every trend of the times and established a huge business empire. In the process, she and the shady investor Lu Beichen went from "monarchs" who tested each other to partners fighting side by side. Finally, after revealing their background and defeating powerful enemies, she was crowned the richest woman and gained a love that spanned a thousand years.
