Lin Bei, a modern social animal, accidentally traveled to Zhaoyao Mountain in "The Classic of Mountains and Seas: Nanshan Yi Jing", bound to the "Ancient Pinduoduo" system, and was forced to open a shop selling Zhu Yucao, Migu flowers, unicorn meat jerky and Yupei pendants. He originally wanted to keep a low profile, but due to a series of strange customers and one-star negative reviews, he shocked the world. The Emperor of Heaven, the underworld, the demon clan, the mountain gods... All forces came to visit. Lin Bei had to upgrade from "a lousy shop owner" to "the number one e-commerce boss in the three worlds", and finally discovered the truth about the system - and the real reason for his time travel.
