In an absurd world of immortals, all the immortal sects have their own agendas, and the boundaries between good and evil are obscured by layers of 'formulas', 'oaths' and 'rules' that seem reasonable but are actually bizarre. Lu Youan entered Taoism ignorantly, and encountered absurd experiences, battles, friendships, betrayals, redemption and love along the way. He was forced to constantly break common sense. In the absurd interactions with partners with distinctive personalities such as Miao Fulu, Cang Shisan, Xuan Yulan, and Gu Youyou, he gradually realized that the so-called standards of good and evil, and the immortality of immortality, are ultimately just a journey of self-consistency and peace. In the end, Lu Youan gave up on the so-called 'Formula of Immortality' and chose to be content with his true nature. The protagonists also followed their own independent paths to immortality, leaving behind countless absurd jokes and memorable spiritual warnings.
