Amid the ruins of the apocalypse, the obsessive orphan Shen Mo awakens a bloodline limit that lets him copy architectural blueprints and turn them into real supplies. But an enemy nation's princess forcibly binds him to a System, turning him into a pawn in the “Death Game Space.” In secret, he builds an Eden and traps the princess in a maze of his own design. Each level she clears unlocks another lethal piece of advanced technology. As fragments of his memory return, he discovers that he and the princess are twin experimental subjects, and that the “Pluto Project” conceals a shocking conspiracy. In the end, Shen Mo devours the cores of two civilizations, becomes the Bloodline Hades, and takes control of his own fate and the shape of the post-apocalyptic world.
