Chen Fan is an ordinary bookstore owner. After his parents died in a car accident, they left behind 200,000 yuan in debt. His gold-digging girlfriend ran off with a wealthy property developer, and his bookstore was about to be repossessed. Just when he had nowhere left to turn, he discovered that every night at midnight, his bookstore could connect to ancient times! Even more astonishingly, his first visitor was Zhu Yuanzhang. Chen Fan casually offered him a few suggestions, which actually helped Zhu Yuanzhang rebuild Yangzhou City. In return, Chen Fan received a collection of antiques worth a fortune. From then on, emperors from different dynasties began visiting one after another. Chen Fan became the secret weapon helping ancient emperors solve their problems while turning the antiques they gave him into money, gradually expanding his bookstore into a thriving business.
