Eventually, he accepted the request, and took a year and a half to annihilate the demons. However, when they finally returned for their reward... "Please rethink this, Your Majesty !!!"

Eventually, it was pushed through by the power of numbers, and the territory was reduced to one-third. This is a story that begins from here. Make full use of "modern knowledge" and "cheat skills" to revive the territory and aim to make it the richest territory in the kingdom. And to regain the stolen territory.
