Isekai Kenkokuki

Isekai Kenkokuki takes an unusual path for the genre. A man reborn in another world as an abandoned child is entrusted with other abandoned children, and he uses his knowledge of the old world to help them survive. The premise is practical from the start: first comes learning how to prepare and cultivate the land, and then the community slowly grows as more orphans gather. That methodical focus is the series' strength, with each step grounded in real problem-solving. The trade-off is pace. The series moves slowly, and readers who want big battles may find it too quiet. The logistical and political details can also be dry for some. Still, it's a satisfying read for anyone who enjoys watching a society grow from nothing. If you like isekai where planning matters more than power, this is worth a look.
