Unfortunately, Tian was framed and lost miserably during the competition. His father died of excessive anger and vomited blood. Tian became the target of public criticism and became cowardly and pessimistic. In order to fulfill his father's wish, Tian opened a martial arts school to find a successor.

The two later developed a delicate triangle relationship with Tian's sister Tan Xue (Wu Wenxin). Fei has always been wary of Tian. When he learned that he had a successor, he ordered his good friend Ping to assassinate Tian.

Nan breaks up with her father for Fei and helps him assassinate his enemies in the court. Unfortunately, she is caught and Fei is captured. In order to protect himself, Fei kills her...
