Qin Xuan, the successor of the Xuan Medicine Sect, went down the mountain on the orders of his junior sister Mo Rushuang. He was charged with the dual tasks of treating young Chen Yan's strange disease and recovering the nine mysterious wooden boxes that were his master's relics. During the execution of his mission, Qin Xuan defeated the provocation of the rich second generation and became involved in the power dispute in Yuncheng. In the end, Jiangdong's underground forces competed for the top spot in Jiangdong, and Qin Xuan became the king of the underground.
