Reincarnated as a Vampire Count: Forging an Empire of Blood and Steel

They threw me away because their system was rigged. So I decided to build my own. On Earth, I was just a university student whose life was ruined by corrupt professors and a family that turned their backs on me. One fatal step on a dark road, and it was over. But instead of the afterlife, I woke up with a splitting headache, a thirst for blood, and the title of a Vampire Count in the frozen north of the Demonic Lands. My inheritance? A crumbling castle, a bankrupt treasury, grumbling dwarves, and starving beastmen. Oh, and a greedy neighboring baron who sends werewolf assassins to steal my iron mines. They think I’m just an impulsive, mad boy-lord. They don't know that my blood magic can forge deadly steel spikes directly inside my enemies' veins. Or that my Earth knowledge is about to turn this backwater into a brutal industrial powerhouse. Aided by my fiercely loyal banshee-boy advisor—whose screams now power my new blast furnaces—I will forge an empire of blood and iron. The world is torn by a holy war between the Goddess of Order and the Demonic Brotherhood, and the summoned "Heroes" are playing their comfortable games. Let them. I don't care about their holy wars. I will never be discarded again.
