Maoshan disciples Ao Tianlong (played by Lam Ching-ying) and Da Huang (played by Kent Cheng) both fell in love with their master's daughter Meng Meng. Before his death, the master set up a test to see who was more sincere between the two. Da Huang won the master's trust with a trick. Although Meng Meng was in love with Tianlong, she had no choice but to obey her father's orders, so Tianlong left in anger. Eighteen years have passed. Da Huang and Meng Meng's son Lian Gao (played by Jin Shaolong) has grown into a handsome boy, and Tianlong's daughter Ning Hong (played by Gigi Lai) has also grown up. Tianlong and his daughter returned to their hometown to visit relatives that day. On the way, they encountered a red-robed fire ghost causing trouble in the world. Tianlong took great pains to subdue it and locked it in a ghost cage. After returning to their hometown, Da Huang and Tianlong still had a gap in their hearts and were hostile to each other. Lian Gao accidentally released the fire ghost, and the fire ghost's magic power increased greatly at this time. Tianlong and Da Huang could no longer deal with it alone. In order to deal with the fire ghost, the two finally put aside their prejudices and cooperated again.
