Rein is an enchanter who strengthens equipment with his magic, working as a valued support mage within one of the realm's major guilds. His sudden expulsion comes as a complete shock, justified by the absurd reasoning that every piece of gear in the guild has already been enhanced to its limit, rendering his services unnecessary. Outraged by this dismissive treatment, Rein decides to take back the enormous amount of mana he had poured into the guild's weapons and armor over the years. He channels all that reclaimed power into a seemingly worthless copper sword, which is miraculously transformed into a cheat-level weapon boasting ten thousand enhancement points. Possessing no combat experience but armed with magic that can turn any ordinary object into overpowered gear, Rein sets off to forge a new and carefree life as an adventurer. His journey unfolds in a world where magic and science intertwine, and he soon encounters new allies, including the beautiful and famous knight Lily and the noble daughter Martina, who recognize his extraordinary abilities. The narrative follows Rein as he grows from a discarded support mage into a great adventurer, all while exploring the deeper secret of his enchantment magic that allows it to evolve even further. The story balances wild humor with layered character drama as the protagonist learns to enjoy a second life free from the constraints of his former guild.
