The protagonist Yun Xiao is the last Taoist priest at Zhongnan Mountain's "Qingyun Temple". He was adopted by his master since he was a child, but he has no interest in cultivating immortals or observing the rules and regulations. He only yearns for the "worldly life" at the bottom of the mountain - eating hot pot, playing with mobile phones, falling in love, and being an ordinary person. However, the master left a will before his death: if Yun Xiao dares to go down the mountain and return to secular life, the "Qiankun Mirror", the magical instrument of Qingyun Temple, will break into pieces on its own, causing the spiritual veins of Zhongnan Mountain to be disordered, and the villages under the mountain to suffer natural disasters. What's even more troublesome is that the master secretly bound him to the "Three Purities System". The system tasks are all "promoting Taoism", "repairing spiritual veins" and "accepting apprentices and teaching skills". Failure to complete them will trigger punishments such as "single to old age" and "zero wealth luck". Yun Xiao was forced to stay in the Taoist temple and embarked on the absurd path of spiritual practice of "while trying to return to secular life while being forced by the system to become a 'top Taoist priest'".
