Kou Jin, a useless soldier who was despised by the entire army, could detonate starship nuclear weapons with his own body, but was regarded as a walking disaster. The imperial tactician Li Zhao secretly planned to make him into the ultimate weapon against the alien swarm; the rebel leader Heruk wanted to use him to detonate nuclear explosions throughout the universe to reshape order; the AI personality Isa longed to devour his fear to become a god. When the mercenary Thorne who was saved by him discovered the truth of the massacre, the ten-year-old orphan Xiao Ling sacrificed his body for him - a nuclear chain reaction that no one dared to start was exploding from the humblest dust to the top of the stars.
