During the prosperous Tang Dynasty and Wu Zhou Dynasty, the Emperor Ziwei, the reincarnated Emperor, granted amnesty to the people. However, when the yin and yang reverse, the evil spirits lurking in the world are waiting for the opportunity to move. The remnant demon god from ancient times is trying to make a comeback in the human world. In the prosperous age, humans, demons, and devils are mixed together. The Empress of China entrusted Prime Minister Di Renjie with the important task of secretly establishing the "Demon Suppression Division" to suppress evil spirits. At this point, although humans, monsters and demons coexist, there are still undercurrents surging above the temples and in the rivers and lakes. The dormant demon is ready to move, trying to overthrow the rule of the prosperous age. Demons are everywhere, and the right path has been raised one after another to save the Zhongyuan world from water and fire. Su Baizhi, a disciple of Kunlun, was ordered by his master to go down the mountain to help Wu Zhou kill the demon. On the way, he happened to meet Hehuan, a young witch from Miao territory, and they met and went to Beijing together. Then, at the invitation of Duke Di, the Japanese witch, the traveler from the Western Regions, the Indian girl, the Qingqiu spirit fox... Everyone formed the "Mulan" team to solve the weird and strange things that happened in Chang'an. Yin soldiers took advantage of the situation, fox monsters brought disaster to the world, and Dunhuang ancient tombs... Behind each case revealed the unknown darkness in the prosperous age. However, as everyone gets closer and closer to the truth, who is the real "devil"?
