Humanity awakens in the Divine Sky Realm, a cosmos of floating islands where power and peril intertwine. The system grants exceptional individuals extraordinary abilities, and Lein—a former office worker—inherits the SSS-rank talent Infinity Duplicate, capable of replicating anything from mundane objects to god-tier materials. Mastery demands patience. Even creation itself requires process, and Lein understands that ascending to supremacy cannot be rushed. The Divine Sky Realm promises the transcendence Earth's masses fantasized about: soaring freely, leveling mountains, conquering every frontier. Yet human nature persists—ambition without restraint, blind to consequence. Humans presumed themselves the universe's chosen, unaware that other races received identical blessings. Wood Elves, Dwarves, Dragons, Goblins, and countless species emerged with inherent advantages that render human biology primitive by comparison. Survival in this realm demands more than luck; it demands cunning, sacrifice, and relentless growth. Lein's duplication ability opens infinite possibilities, yet infinite potential breeds infinite danger. Floating islands now serve as kingdoms for the ambitious, battlegrounds for the strong, and tombs for the careless. In a realm where dreams materialize alongside nightmares, where desires and terrors become tangible forces, humanity must adapt or perish. The SSS-rank talent offers one man a path to supremacy—but can ordinary humans endure the cost?
