After the Demon King's War ended, Haruto Kamiya, who really supported the logistics of the Brave Team, rejected the title and bounty and came to the most remote Gray Birch Village on the mainland with only an old toolbox. What he possesses is not a combat skill that can destroy a city in one blow, but a [universal workshop] that can string together basic skills such as reconnaissance, repair, alchemy, construction, cooking, and farming into a complete process. Haruto just wants to build a house that won't leak, plant a few vegetable plots, fish and take a nap. But dried up canals, refugees after the war, abandoned orcs, former teammates who lacked common sense, and front and rear logistics generals who even the Demon King's army found troublesome came to the village one after another. As mills, bathhouses, clinics, markets and disaster prevention fortifications were built, this small village that should have disappeared from the map gradually became a place where the strong were willing to lay down their weapons and ordinary people dared to live again. But when the royal capital prepares to transform Gray Birch Village into a new border fortress, Harukai discovers that maintaining a "peaceful life" sometimes requires more skill than defeating the Demon King.
