Banished To Deadland, He Built and UNDEAD ARMY So Strong Even Kings Trembled

After getting kicked out of his noble family for becoming a NECROMANCER — the fantasy equivalent of majoring in unemployment — this former archaeology nerd heads into the world's most dangerous wasteland expecting hardship, monsters, and survival. Instead, he accidentally discovers that his necromancy is completely broken. While normal necromancers raise one sad skeleton at a time, this guy treats ancient battlefields like archaeological loot boxes. The older the bones, the stronger the undead. Suddenly every ruin is a treasure chest, every graveyard is a recruitment center, and every skeleton is a potential employee. Meanwhile, his runaway ex-fiancée decides exile sounds more fun than her actual family, so she follows him into the wilderness, spends most of her time flirting unsuccessfully, and watches in horror as his undead construction company grows faster than a startup with unlimited funding. Soon he has skeleton farmers, skeleton hunters, skeleton warriors, brick factories, warehouses, houses, and enough undead labor to start building an entire kingdom. Everyone else sees a cursed wasteland. He sees PRIME REAL ESTATE. Turns out the world's worst necromancer is actually the world's first undead city planner.
