In the Tianxuan Immortal Realm, young Liu Xu was involved in the drama within the Immortal Sect due to an accidental collision. From then on, he started a series of absurd and bizarre spiritual journeys. Sometimes he becomes a 'savior', sometimes he is regarded as a 'heretic', he joins forces with various unreliable characters in the world to fight against authority, and experiences various absurd encounters such as broken vows, love-hate entanglements, friendship misunderstandings, and identity confusion. Every time he touches the boundaries between immortality and good and evil in the world, he gradually reveals the illusion of "immortality" with sharp complaints and helpless humor. In the end, through self-salvation, reconciliation with the world, and self-harmony with the world, he realized that true "immortality" is not endless life, but self-consistency and peace of mind.
