Shen Mo is a survivor of the "Martial Arts Forbidden Zone" - ten years ago, the "Longhu Mountain" where his parents lived was exterminated due to the discovery that "the seal of the ancient evil creature was loose". He escaped by chance and was adopted by the killer organization and became a top assassin. Now he returns to the city. On the surface, he is a bar owner, but in fact, he is investigating the truth about the "revival of the restricted area". He discovered that the man behind the annihilation of the family was the "Tianshu Group", which transformed ordinary people into "orcs" through "genetic medicine" and tried to open the "door to the forbidden area" to release the evil creatures. Shen Mo teamed up with the "Police Superpower Team" and the "Orphan of the Guwu Family" to sneak into the Tianshu Group laboratory and discovered that his blood was actually the "sealing key". In the end, he used himself as a lock, recast the seal, and became the legend of the "forbidden zone hunter" in the city.
