At the beginning of the founding of New China, Taoism signed a "hundred-year covenant" with the demon world, stipulating that demons would not appear in the world. Now that the spiritual energy of heaven and earth has revived, the agreement is about to expire. There is a vague force controlling some demons and spirits, and incidents of demons causing trouble and harming people begin to appear in various places.
The new generation of Taoist monks confront the demonic forces trying to break the balance, while uncovering the truth behind the agreement a hundred years ago.
As the leader of the new generation of Celestial Masters, Zhang Yuanqing, the successor of the 65th generation of Celestial Masters in Longhu Mountain, was sent down the mountain by his master to investigate the frequent supernatural incidents in various places because his parents were killed by demons and he possesses the special physique of the Xuanyin body, which makes him terrifying in combat. This led to a series of incidents.
