In the twenty-second year of Hongwu, the protagonist transmigrates into Li Jinglong, Duke of Cao. Hoping to coast through life and eat for free, he runs into problems: the household is short on money, and Ming paper currency is losing value. Thinking outside the box, he sets up a street stall in Yingtian Prefecture, trading paper money for rare treasures. His scheme sets the whole city abuzz and catches Zhu Yuanzhang’s attention. He complains about not wanting to work even as his genuine abilities revive the Ming dynasty’s finances, carving out a feel-good path all his own between slacking off and making a name for himself.
