When the game descends upon reality, dungeon monsters run rampant across the globe, and everyone awakens a class! Su Ren, who has traveled from another world, is regarded as a completely useless nobody during the awakening ceremony, with every attribute on his status panel stuck at 1. But no one knows that he has unlocked the world's one and only hidden class: Concept God! By tirelessly honing his proficiency, he masters the draw-slash technique, cutting through everything with a single stroke. Armed with the Thousand-Blade Demon Sword, he ignores all defenses and shields. From a useless boy mocked by the entire city to someone who kills regional bosses with one slash, tames the ancient divine beast Phoenix, and shocks the entire nation during the highly anticipated national examination, Su Ren forges his own legendary path as the Concept God with the long blade in his hand, facing conspiracies from jealous rivals and bounties placed on his head by foreign forces.
