A Carefree Life in Another World

A story about a protagonist who has lived a fairly happy life being reincarnated into another world. Born as the third son of a poor farming family, he quickly cuts ties with relatives who would hold him back, and avoids troublesome matters with all his might. While aiming to travel through dungeons, ancient ruins, secret lands, and magical realms, he builds a secret base and becomes a shut-in. He rises to success while selfishly enjoying the other world. Updates are irregular. I'm writing this as a pastime. Please read it casually as if it were just killing time.
