I Have the Power to Exorcise Inner Demons

"Your ancestor is an immortal? Isn't he the kid in front of me who begged me to get rid of his inner demons? He traded all his protagonist's auras to me!" "What? You get 500 years of life for removing a demon from your heart? No! The price is too low!" "What? Are you going to join the demon-pulling sect? Have an innate demon body? Well, it's a little short of that. I'll give you some benefits and I'll let you become an outer disciple!" This novel and its characters are purely fictitious.
