Li Xiaoyao, the son of a butcher, accidentally rescued a chicken, and was involved in a dispute between immortals and heroes: the chicken is the descendant of the ancient mythical beast, and they share spiritual veins in order to repay their kindness. Li Xiaoyao has a "bad luck constitution", but he has repeatedly counterattacked in all kinds of strange disasters, and relied on humor and wit to conquer countless monks. Together with Tang Miaomiao, Bai Wuyou, and Luo Qingyi, they formed the "Three Unreliable Heavenly Groups" and experienced multiple crises along the way such as seizing treasures in secret realms, defeating monsters by breaking bricks, accidentally breaking into the mortal world, and fighting against demon sects. While harvesting friendship, love and growth, you also uncover the secrets of the catastrophe between immortals and demons. In the end, in the epiphany that "life is just a smile to ask for immortality", Li Xiaoyao and his companions solved the catastrophe of immortals and demons with wit and unity, and fulfilled their wish for immortality. The story ended with laughter and tears.
