The Necromancer's Flying Fortress

Aiden York is transported to the world of Highway Survival, but starts with only an immobile windmill. Facing a crisis of punishment, he calmly develops his base, upgrading the windmill into a flying fortress. He builds an army of undead and mechs, crushing players from all nations, Demon Kings, and god-level bosses. In the end, he merges with a Godspark, ascends to become the God of the Undead, seizes control over life and death, and becomes the supreme ruler of the world!
