In a crisis-ridden city, scrap collector Lin Feng and his seriously ill sister Lin Xi depend on each other. The fall of a "Black Star" meteorite awakened Lin Xi's healing powers, but also attracted the pursuit of Deep Blue Technology's "Hound Squad", with the intention of using it to repair the genetic defects of the experimental subjects. In a desperate situation, Lin Feng was scratched by a meteorite fragment, awakened "entropy reduction control", disintegrated the team's weapons and escaped with his sister.
They were helped by Chen Jiu, the former "scavenger" of the Special Administration Bureau, and learned that those with superpowers would be physically annihilated if they were not promoted to S-level within three years, and Deep Blue Technology was arresting superpowers to extract "star core genes". In order to raise money for medicine, Lin Feng entered the black market and later formed "Scavengers" to fight against the pursuit. As the situation develops, he discovers that he is actually the clone of Lin Chen, the "dragon vein gene user" who disappeared ten years ago, and is also involved in the "Observer" conspiracy to harvest the earth's superpowers.
From fighting for the "Black Star" fragments, revealing the secrets of the ruins, to uniting all forces to build a global communication network for supernatural powers, Lin Feng led everyone to struggle in multiple sieges. In the end, in order to protect the earth's civilization, he faced the final battle of the "Observers" and wrote a legend of survival in the urban supernatural world with sacrifices and choices.
