Reborn As A Ghost: Time To Build My Undead Army! - Chapter 84

You are a master, can you give birth to dragons and tigers?
You are a superman, can you call the wind thunder?
Excuse me, I am not targeting anyone, everyone in my eyes, it is rubbish!

Kaius just wanted to unlock his class - instead, he restarted the apocalypse. After years of training, Kaius has barely acquired the first two of his family’s legacy skills. Powerful and vanishingly rare, the method of creating them is a secret people would kill for. Now they might be the only thing that keeps him alive. Narrowly surviving a bandit ambush, he gets trapped in the Great Depths- a world spanning dungeon.
