Modern-day overworked corporate drone Wang Ning transmigrates into the carefree young heir of the Duke of Zhenguo's household. Determined to slack off from then on and live the life of a dissolute young lord, indulging in every pleasure with a harem of wives and concubines, he ends up benefiting his country and its people through his extravagant, debauched lifestyle. He becomes famous across the land and a national treasure that every country fights to claim!
Duke of Zhenguo: The disinfectant my eldest grandson invented turned out to be peerless liquor. The Duke of Zhenguo's household is making a fortune!
Princess Royal: The seasoning my husband used to improve our meals turned out to be premium fine salt. East Chu is making a fortune!
Crown Prince: I went to the brothels with my brother-in-law, and he helped me open a foot spa. I am making a fortune!
Emperor Chu: Good son-in-law, how about I marry all my daughters to you?
The other nations: We will do whatever it takes to bring Wang Ning to our countries so he can enjoy a dissolute young lord's life of luxury and pleasure.
