It tells the story of Tang Shouzhen, who was regarded as a crazy scholar by the world during the drought-ridden Longyou in the 17th year of the Apocalypse. Holding a fire stick picked up from the stove of his ancestral home, he claimed to be the successor of the Three Pure Paths and made a vow to kill demons and revive the righteous path. He has always been trapped between the pale fantasy of the mental hospital and the reality of slaying demons in the wasteland, repeatedly struggling between the identities of a "sane madman" and a "righteous monk".
The gangster Sang Mancang caught a glimpse of the power of his innate mind, and wanted to take advantage of him, but he became his only protector along the way. Tang Shouzhen's sincerity and faith became the most perfect sacrifice in the eyes of Zuo Wangdao. The other party weaved the beautiful illusion of Qingxu Sect for him, and lifted his Taoist heart into the clouds before crushing it. After the collapse of faith, worldly misunderstandings, and heavy blows from scams, Tang Shouzhen finally uncovered the illusion and realized the true meaning of "the right path does not lie in the mountain's classics, but in the heart and perseverance." Together with Sang Mancang, he picked up the fire stick and embarked on the lonely road of slaying the devil knowing that it was impossible to do.
