The story takes place in the world of immortality where the dual dimensions of dreams and knowledge are intertwined. The protagonist, Lu Fazhao, is a fifty-year-old middle-aged man who was judged to be a useless person for cultivating immortals due to his "aura allergy". He works as an ancient book restorer in the "Guixu Wasteland", a place of extraordinary spirituality on the edge of the "awakening world". In an accident, he repaired the fragments of the "Chenghuang Sutra of Immortality" and found that although he was unable to absorb spiritual energy, his physical body was extremely strong in the unique spiritual environment, and accidentally touched the seal of the "Taichu Yuan Magnetic Wheel". From this, he embarked on a path of physical cultivation that was very different from ordinary people's "taking one's own body as the world, and not seeking externally". In the process of exploring the "Forgotten Library" and "Light Sleep", he met Yun Shigna, an enlightened monk who believed in "momentary eternity", and Gong Shuqiao, a master of weapon repair who tried to use "technology" to analyze dreams. As his cultivation level increases, Lu Fa is gradually involved in the dispute between four major ideals: the ancient powerful "Immortal Lord" wants to devour the "Dream Homeland" to achieve eternity, and his behavior will cause the dreams of all living beings to dry up; and the ideological dispute between the Artifact Cultivation Alliance and the ancient cultivation sect has also intensified. Lufa relies on his unique advantages in the spiritual land and his deep understanding of "cause and effect" to deal with all parties. In the end, at the boundary between the "origin of knowledge" and "eternal sleep", based on the "inner heaven and earth" he created, combined with the "immortal confinement of the stars in the sky", he stopped the Immortal Lord's plan to destroy the world, and found his own destiny - to protect the flow balance of dreams and knowledge, and become a bridge connecting "moment" and "eternity", "tradition" and "innovation".
