floating cities and islands in fiction

Humans of Earth were transported to the Divine Sky Realm, a world brimming with fortune and danger. In this celestial domain, humanity now dwells upon floating islands, ascending as rulers. When else will you get the chance to be a king and vie for supremacy? The system bestowed powers upon chosen individuals, granting limitless luck. Lein, an ordinary office worker, received the SSS-rank talent - Infinity Duplicate. There was nothing in this world that he couldn't duplicate, not even god-tier materials. The path to becoming the strongest lay before him. Yet, Lein knew all too well that it required a process. Even the gods needed a process to create the universe. The Divine Sky Realm offered a fantastical life that Earth's humans had always dreamed of. Soaring through the skies, shattering mountains, rising to the pinnacle in all endeavors. But humans remain humans, wherever they are, driven by their innate nature: greedy and unaware of their limits. Humans believed they were the sole inhabitants of the universe, thinking only they received the system's fortune. But reality proved otherwise. Other races in the universe were granted the same blessings, without distinction. In fact, the human physique was considered low-tier. Races like the Wood Elves, Dwarves, Goblins, Dragons, and countless others possessed bodies that defied the heavens from the outset. Could humans survive in the Divine Sky Realm? We can only hope for the best. The humans found themselves in a realm where dreams and nightmares walked hand in hand, a place where every desire and fear took form. Floating islands became their new kingdoms, a testament to their newfound power and ambition. Lein, an unremarkable man back on Earth, now wielded the power of Infinity Duplicate, a gift that could make him invincible.
