The three brothers of Chi Tu Long learned that their master was injured by a dragon demon that was about to transform into a flood dragon, so they volunteered to subdue the demon. The elder brother arrived at Shengping Town and encountered the He family snatching babies. He learned that the demon person who retrieved the baby from the skeletal spirit was Ke'er, the daughter of the 'Plum Blossom Deer Spirit' Su Su. Ke'er informed them that her mother was being controlled by the dragon demon in the Yin Wind Cave. Strange occurrences continued in Shengping Town, as the children of the Xu family were behaving abnormally. Wu You and Chang Le set a trap to capture the bat spirit; meanwhile, in a remote mansion, Chi Tu Long saved the young master Rong Hua. The dragon demon became aware of the formidable enemy nearby, and a fierce battle ensued. Because the dragon demon possessed powerful magic, Chi Tu Long was severely injured. He took out the silk bag given by the master, realized the true meaning, and entered the dragon demon's body to annihilate it. Su Su expelled the cultivated fairy pearl to save the barely breathing Chi Tu Long, returning to the deep mountains hoping to achieve immortality one day.
