During the Zhenyuan period, the goddess Bai Ze, who was in charge of the human and demon worlds, died unexpectedly and Bai Ze Ling disappeared. Demons and beasts roamed freely in the human world, committing many evil deeds, and more and more bloody murders occurred. At this time, the leader of the hundred demons, Zhu Yan, who has transformed into a human form, changed his name to Zhao Yuanzhou and took the initiative to "surrender", proposing to assist the court in setting up the Demon Hunting Division to hunt down demons and quell the rebellion. Wen Xiao joined the Demon Hunting Division with his childhood sweetheart Zhuo Yichen, the Consul of the Demon Hunting Division, who is proficient in investigation and swordsmanship; Pei Sijing, a cold archer who used to be a demon hunter in Chongwu Camp; Bai Jiu, a prodigy doctor who is proficient in medicine, kind and timid, formed a demon hunting team of the Demon Hunting Division. The demon beasts recorded in the "Classic of Mountains and Seas" appeared in front of everyone one by one. In the process of solving the case, everyone gradually discovered the cruel truth behind the demon beasts' evil deeds. On one side is the great responsibility of the world, and on the other side is the return of the lover to dust. Can the indestructible friendship of the demon hunting team and the love of the top demon beasts in the wilderness and the goddess break this dilemma?
