Exorcism

Lin Jun traveled to a Xia Dynasty where monsters were rampant. The good news is that he became a demon slayer, and although he is a third-rate one, at least he is less likely to die. The bad news is that this profession doesn't seem to be that popular. Everywhere you go, you will be kicked out immediately after the demon slaying. So, he planned to travel all over the mountains and find a place like Toussaint. No? Then build one yourself!
