I recommend the following novels to you. They are all similar to taking Ninth Uncle as your master: - "Master Exorcist" was also a story about master and exorcism. It was very interesting. - "Zombie World: Sacrifice to the Corpse King at the Beginning" was also a story about zombies. Uncle Nine also appeared. - Zombie: Rejecting Uncle Nine at the Beginning was also a story about the zombie world, but the protagonist did not acknowledge Uncle Nine as his master. I hope you like my recommendation. Muah ~
