Xuan Qing, a Taoist priest who grew up in Qingfengguan and was half-experienced in Taoism but passionate about Taoism, was ordered by his master to go down the mountain to practice. However, when he first entered Wangyue Town, he unexpectedly met Wang Dali, a simple and brave man. One has a simple dream of "killing demons and becoming famous" and carries a "half-baked magic weapon" given by his master; the other relies on brute strength and sincerity, often carrying a butcher's knife as a weapon. The two became connected due to a bizarre "thief possessed by evil" incident, and they embarked on a journey to slay demons together.
