Easygoing Territory Defense by the Optimistic Lord: Production Magic Turns a Nameless Village into the Strongest Fortified City (Manga) Vol. 6

A FORMER CHILD PRODIGY’S “USELESS” MAGIC BRINGS HIM CLOSER TO HIS EASYGOING GOALS!
After giving the neighboring villagers haven from their tyrannical lord and undertaking the construction of new dungeon facilities, Van is finally starting to see the signs of the easygoing life he yearns for! Even better, thanks to his victory over the forest dragon, he now holds the title of baron, a position that allows him to reform his territory without interruption from his family. As Van continues to expand and improve his land, his accomplishments also spur Arte, who has spent her whole life looking down on her own magic, into action. What new adventures await Van and his ever-growing list of allies?!
Series Overview: Van, the fourth son of a powerful noble, is only two years old when he remembers his past life as a salaryman in Japan. With his adult brain in a young body, he’s considered a child prodigy…until he displays the “Production Magic” skill when he turns eight. In a family that favors offensive magic, this crafting skill is considered useless in battle, and Van is banished to oversee a tiny country town in disgrace. With only his personal maid, his father’s butler, a knight, a rescued slave, the memories of his past life, and his “worthless” magic, can Van improve the fortunes of this little village—and himself?
