Song Qian of Taohua Village has been foolish since he was a child. He devoted himself to protecting his widowed sister-in-law Xu Taohua, but was thrown into the devil's cave by the bully King Mazi. In the cave, he received the inheritance from the Lotus Immortal Emperor, learned superb medical skills and exercises, and regained his sanity. After returning to his hometown, he punished evildoers and rescued people with skill, and met Liu Muyun, a woman from Jiangcheng who was seeking medical treatment. He successively exposed Xu Junhao and Xu Zhenhai's father and son's plot to poison and frame the Song family. Following the clues of the jade pendant, Song Qian and Liu Muyun went to the Lotus Mountain in Jiangcheng to find their long-lost father. They collected the fragments of the spiritual lotus and started a new journey of healing the disease, finding the lotus, and reuniting the family.
