[Insight into the human heart is more terrifying than ghosts; in the game of the world, I am the only one with a Taoist heart]
He was once a genius rarely seen in Maoshan for a century, but due to the jealousy of his classmates and the injustice of his master, he was deprived of his cultivation and expelled from the mountain. Living in the city, he saw evil that was deeper than ghosts - the greed, betrayal and indifference of people's hearts.
From then on, he put on sunglasses to isolate himself from the ugliness of the world; wore an old shirt and blended into the rolling world of mortals. In a corner of the city, he opened a small paper shop.
Clearly mark the price, pay for the goods first, and do not involve cause and effect—this is his rule.
Tie paper to attract souls, reduce obsessions, and make transactions clear—this is his method.
With the addition of the only clerk "Fat Man" Wang Tiezhu, policewoman Lin Yao's transition from doubt to cooperation, the involvement of wealthy siblings Chen Jingwei and Chen Zixuan... A seemingly inconspicuous paper-making shop has become the core of insight into the weirdness of the city and the ghosts of the human heart.
Water tank ghosts, ghost calls, Internet celebrity sacrifices, crying dolls... Behind every supernatural incident is the evil of the human heart. And in the shadow of all this, his former senior brother Xuan Ming is practicing the paranoid concept of "human nature is inherently evil", intending to strip away the ugly human nature and establish a pure kingdom of ghosts.
Faced with the ultimate challenge from his old enemy and the darkest malice in the world, how will Zhang Qingxuan use the world of mortals as his dojo? After witnessing the deepest hell, how will he still choose to protect the preciousness of this human spark?
