Detailed ending:
Cheng Xiuhua (Zhang Jingchu) lets Sun Hao go to save him (Jason Wu), but Sun Hao bears a grudge because he didn't catch Zhang Dachu (Zou Zhaolong) last time. At the same time, he solves another mutant, a female mutant, who thinks he is not very powerful and insists on making Zhang Dachu look good and refuses to leave.
Xiuhua stayed there to deal with another mutant, who was seriously injured and died. Then Sun Hao listened to Xiuhua's last words and decided not to retaliate against Zhang Dachu. He trained Sonny (Aaron Kwok) to practice flying knife skills in the wild, and returned to Zhang Dachu after his success. At this time, Zhang Dachu has been pestering Chen Aner (Shu Qi) and wants Chen Aner to follow her.
Later, Chen Aner cooperated with the police to arrest Zhang Dachu, and Sonny came to save Chen Aner from a decisive battle with Zhang Dachu. On the other hand, in order to deal with another mutant, Sun Hao ignited a gas explosion in the hotel and died together. At the same time, Chen Aner blocked Zhang Dachu from saving Sonny for him, and he fainted. Sonny killed Zhang Dachu angrily.

Sun Hao (Jason Wu) and Cheng Xiuhua (Zhang Jingchu), mainland experts with peerless martial arts, were invited by the police to assist in the investigation. Four ordinary people living at the bottom of society, led by Zhang Dachu (Zou Zhaolong), accidentally inhaled the biochemical gas left by the Japanese army during World War II, and their bodies changed, becoming invincible mutant criminals.
Sonny (Aaron Kwok), a little fellow, was born in an ordinary family and engaged in drama. He got the biochemical power by mistake, which became the biggest key to clean up the mutant criminals. The mutated Sunny attracts the attention of the police and the charming but frustrated beauty anchor Angel (Shu Qi).
Angel, an opportunist, took advantage of Sang Ni's affection for her to revive her career in crisis, and successfully shaped the image of Sang Ni as an urban hero who stood up for the brave and helped the weak. Sunny, a hero's dream, was finally ambushed by Da Chu and others. Xiuhua unfortunately left because of Sun Hao's carelessness and underestimation.
