A mysterious military organization transforms ordinary people into biological weapons with far superior physical strength, reaction and speed by changing their genes, and sells them to gangs. Qiangfeng (played by Andy On) is one of them. However, he is kind-hearted and unwilling to help the evil. Instead, he chooses to escape the control of the organization and transform himself into a "black man" who punishes evil and promotes good, promoting justice around the world. Zeus, the leader of the military organization, learned about Qiangfeng's escape and sent the cold-blooded and cruel killer Liang to bring Qiangfeng to justice. At the same time, a crazy scientist attempted to combine the genes of humans and animals to create a new species. As you can imagine, he got a group of half-human, half-beast monsters. The scientist learned that Qiangfeng's blood could help him get out of the research dilemma, so he also started to hunt down Qiangfeng.
