Seyi made history as the youngest girl ever appointed as a court alchemist, dedicating her days to relentless and exhausting labor. Her grueling routine came to an abrupt halt when a massive horde of monsters launched a sudden assault on the royal city. Amidst the chaos, she lost consciousness, only to open her eyes five hundred years later. The once-grand city had long since crumbled into ruin, leaving behind a world entirely transformed by the passage of time. Freed at last from the crushing weight of her royal duties, Seyi resolves to explore this unfamiliar era at her own pace. She sets out on what is meant to be a quiet, leisurely journey through a completely changed landscape. However, her plans for a peaceful life are quickly derailed when her unparalleled potion-making abilities catch the attention of the locals. Word of her extraordinary craftsmanship spreads rapidly, turning the former court genius into the talk of every town she visits. Instead of traveling unnoticed, she finds herself revered almost like a holy figure wherever she goes. Thus begins the unhurried yet unexpectedly eventful adventure of a brilliant alchemist who simply wanted to enjoy the world in peace.
