Damn It, I've Really Become a Fairy's Inner Demon

Traveling to the world of immortality where desires are rampant and inner demons are raging, Jiang Lin becomes a rootless soul that can only cling to others. Fortunately, he possesses a mysterious heavenly book, which gives him the ability to form a predestined relationship. At first, Jiang Lin just wanted to regain his physical body, but he was always regarded as a demon that troubled people's hearts—— "Holy girl, this person seems to be evil at first glance. You should first ask how many people are in his family." "You are in the Demon Sect, and your heart is toward the light. As long as you start building your character from now on, there will be a place for you in both the righteous path and the demonic path." "What about a concubine? What if her spiritual veins are taken away? Thirty years to the west of the river, thirty years to the east of the river. Don't bully a young girl into poverty!" "Who said that people in Buddhism should be pure-hearted and have few desires? What kind of body is like hell? It hurts others and hurts itself. If I don't go to hell, who will!" He taught the saint of the Immortal Sect to deviate from the teachings, deceived the demon girl to change her ways, stimulated the kendo girl whose heart was stained by the sword to regain her sword, and caused the heartless Buddhist girl of the Tianzong to fall into the world of mortals again... Damn it, I seem to have become a demon?
