The Prisoner of the Cage

Lin Mu discovers an ancient secret: rest isn't just relaxation—it's power. By consuming metallic essence, he can refine his body beyond human limits. But what is the cage that binds him? Is it physical walls, societal constraints, or something far more sinister? As he grows stronger, Lin Mu realizes the true prison might be his own dissatisfaction with reality itself. In a world where cultivation hides beneath modern city life, one young man must break free—or be consumed by his own transformation.
