Easygoing Territory Defense By the Optimistic Lord: Production Magic Turns a Nameless Village Into the Strongest Fortified City (Light Novel) Vol. 1

In this fantasy isekai tale, a reincarnated nobleman with a "useless" skill transforms a village into a prosperous city! And don't miss the manga adaptation, also from Seven Seas-or the anime! Van, fourth son of a marquis, is just a toddler when he realizes he's been reincarnated. Thanks to his literal lifetime of knowledge, he's raised as a child prodigy-until his production magic manifests, and it's the last thing his snooty mage family wants to see! His disappointed father banishes him to a podunk town on the verge of collapse, yet Van can only see the place's potential. Can our hero's bastion of battlements build a better life than battle magic ever could?!
