There is a special group of immortal cultivators hidden deep in Qingzhang Mountain. They eat grains, do ordinary work, practice silently but have the world in mind. Disciple Zhang Mu and his lively and mischievous junior sister Su Ya went down the mountain to exorcise evil spirits and pierce the yin and yang. From the disaster of resentful souls in Jiangcheng to resisting the crisis of annihilation, this group of hermits always quietly took action, using fairy magic to protect the peace of the world, guarding the righteousness of heaven and earth in the mortal world, and performing unknown guardian legends.
