Just after Chang An transmigrates into the body of a noble's illegitimate son, his family kicks him out and sends him to take up a post at Ashen Ridge, a wasteland abandoned for ten years. His brothers are already waiting to see him die in the wild and become goblin food.
No one knows he's awakened a Divine Pact System, signed contracts with witches, and kicked off a building boom!
No heating facilities? The Crimsonflame Witch marches with the troops, burning the enemy to ashes in wartime and firing bricks, melting snow, and clearing land in peacetime. She's a mobile heater and a human bulwark.
Not enough guards? A wolf-eared girl cuts a path with her blade, beheading enemy generals and capturing their banners before battle, then scouting the mountains, opening roads, and taming beasts in her spare time. She's worth an entire order of knights.
To everyone else, Ashen Ridge is a wasteland. To Chang An, it's a treasure trove.
While the surrounding lords are still mocking Chang An for biting off more than he can chew, his witch legion has already opened trade routes, built fortified cities, and cultivated fertile fields, quietly taking the empire by the throat.
