Possibly the Greatest Alchemist of All Time

A salaryman is unexpectedly summoned to another world by mistake, with no way to return home. He’s given a new identity-Takumi Iruma-a younger body, magical abilities, and a chance to start over in this strange land. Wanting a peaceful life, Takumi settles in a small village and takes up work as an alchemist, where he can craft nearly anything he imagines. He spends his days experimenting with his powers and even ends up adopting an unusual pet. Eventually, Takumi leaves for a bustling city, hoping to refine his alchemy and expand his business. As he hones his skills and builds relationships, he might just have what it takes to become the world’s greatest alchemist.
