Lin Yan was scammed out of 188,000 by Zhao Yu, failed to sell ultra-long egg tarts on a desolate mountain, and accidentally entered a cave, time-traveling to Peach Blossom Village in the late Daliang dynasty. He saves A Heng, exchanges instant noodles and ham sausages for antiques, sells a broken bowl for 200,000, and starts the path of reselling modern supplies. Bandits arrive following the aroma, and villagers turn from hostility to following him. Lin Yan builds high walls, takes in refugees, resists the government, and turns Peach Blossom Village into a stronghold in troubled times. But when he can return to modern times at any time, how should he choose?
