[ Fusion Successful ] [ Water Toad + Sky Dragonfly + Nightmare Moth + Bluefang Hyena = Nightmare Hydra ] ---- Yuki Igarashi spent his final days as a terminally ill boy trapped in a hospital ward, yearning silently for strength and liberation before death claimed him. His desperate wish becomes reality when he awakens in a wondrous realm, reborn not as human but as a newborn Frost Dragon with his consciousness intact. A peculiar system manifests—the Dragon God System—binding itself to him despite recognizing he is not its original intended host, yet unable to sever the connection. Though physically fragile in his juvenile form, Yuki unlocks an extraordinary ability: the Dragon God Codex grants him access to extract bloodlines and abilities from creatures around him, combining them within the mystical Fusion Lab. A critical system flaw becomes his greatest advantage—fusing bloodlines generates no cost, allowing infinite combinations and unprecedented power scaling. As Yuki evolves beyond his draconic origins, he attracts the attention of powerful females drawn to his limitless potential, each seeking to claim a place beside the rising Dragon God.
