I Took Away the Body of the King of the Undead

My name is Luo Xiu. I traveled to a world of swords and magic, and captured the body of the undead king who had been sealed for thousands of years. I am the deepest nightmare and demon king of this continent. I am proficient in undead magic and am immune to all magic. I also have succubi, undead knights, immortal lichs, and vampires under my command. I originally thought I could be a salty fish, but I found that all races are eager to kill me... Fortunately, I still have a golden finger, the Immortal King System. As long as I keep spending money, I can gradually regain my peak strength, and I can also summon undead knights, lichs, succubi, and skeleton armies... The humans of the empire, the orcs of the north, the elves of the forest, the goblins of the crypt, the dragons of the mountains, the demons of hell? Everyone begins to tremble. Sorry, the former Lich King, the true emperor of the Holy Continent, is back! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
