Taohua Village in Dajing suffered from a once-in-a-century drought. The villagers had no harvest and were about to starve to death. Su Tao, a little beggar who was picked up by the village, accidentally activated the parallel world communication ability of the ancestral jade pendant - he could exchange materials with himself in another "Prosperous Tang World" with abundant products. She exchanged old porcelain in the village for life-saving food to help the villagers survive the drought; she exchanged wild vegetables for locust-killing powder to solve the locust plague; she exchanged herbal medicine for plague vaccines to save the whole village. In the process, she was regarded as a "little lucky star" by the villagers (for example, her grandma secretly stuffed her with eggs, her uncle took the initiative to help her guard the jade pendant, and the children gathered around to hear stories about parallel worlds). She also met Gu Zhao, a down-and-out strategist. Together, they dealt with personnel troubles such as corrupt officials robbing food, bandits robbing property, and neighboring villages were jealous. Every natural and man-made disaster ends with Su Tao slapping the villain in the face with a golden finger, and the villagers unite to protect her. In the end, she becomes the "living Bodhisattva" of Taohua Village!
