Kougei Shokunin (Craftsman) wa Second Life wo Ouka suru

In both his past and present lives, the reincarnated Wilm was forced to work for exploitative companies. One day, he is suddenly fired for an unreasonable reason, but this prompts him to decide to start a new life free from all constraints. He plans to live a carefree life in the remote mountains, creating things he loves—or so he thought... However, eccentric and influential clients, including a high-ranking nobleman, an S-rank adventurer, and a legendary blacksmith, who admire Wilm, begin to flock to him, and soon the situation escalates into a turmoil that involves the entire country!?
