Unrivaled Necromancer Manhwa

The tower. An unknown place with many rapid changes. Ten years later, I reincarnated into the body of a boy who lives on Earth in South Korea. “The guy who backstabbed me and the one above him… I’m going to rip into them.” The person who reached the top as a necromancer and achieved the class above that, Spirit Master Cha Jinhyuk. With the title of “Unrivaled,” he will take his revenge by climbing the tower as a necromancer (spirit master).
