Necromancer Vs. Gatling Bald Ass

Help! A bunch of bald donkeys are going to hunt me down! They were driving armored vehicles, mumbling nonsense such as six pure depleted uranium bullets, great mercy to save the world, and poor monks to save their donors. My soul traveled to another world, and I found myself becoming the Archmage of the Undead, sitting in the Balzac Necropolis. You have a succubus maid and a demon butler in your hand. I thought I could summon a bone dragon to show off its power, but the bald donkey had a Gundam! Facing the natural disaster of the undead, the opponent actually launched a nuclear bomb! The cemetery is in danger! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
