Chu Fan, the successor of the Taoist temple in the mountains, came down from the mountain with a token of his marriage contract after his master's sect suffered a sudden change, and went to Tianzhou to look for his fiancée Tang Yueling, who had been engaged since childhood. However, because of his simple clothes and unknown identity, the Tang family broke off the engagement in public and verbally humiliated her because of their family views. Chu Fan was disheartened and resolutely broke off the engagement and left alone. By chance, his medical skills and conduct were appreciated by Mr. Lin, the head of the famous Lin family in Tianzhou, and he was interested in recruiting him as his son-in-law. Chu Fan did not rush to agree, but relied on what he had learned to practice medicine in Tianzhou to help the world and relieve difficulties, and gradually won the respect and support of the Huo family, Zhaixin Pavilion, Fanyunfanyulou and other forces.
