Lin Yan, a modern social animal, died suddenly and unexpectedly. His soul traveled to the barren Qingwu Village in the world of immortality and became a boy of the same name. He has been struggling in this world of jungle for three hundred years, working his way up from a casual cultivator who brought Qi into his body to a master of overcoming tribulations. However, when he ascended, he encountered space turbulence and unexpectedly returned to the modern world that he had long been unfamiliar with. At this time, only three years had passed since his "sudden death", and his only sister Lin Xi was in deep depression and trouble. The shadow of her parents' premature death and the weight of life had made this once lively girl taciturn. With three hundred years of memories of cultivating immortals and a master of heavenly cultivation, Lin Yan is determined to make up for the regrets of his previous life, and uses the resources and methods of the world of cultivating immortals to pave a path to immortality for his sister that is far away from suffering. While hiding his identity and integrating into modern times, he secretly cleansed his sister's marrow, cut her veins, and introduced Qi into her body. At the same time, Su Qingyuan, a female doctor who studies paleontology and abnormal energy, interacted with Lin Yan's brother and sister because of a strange archaeological discovery. She was keenly aware of Lin Yan's extraordinary aura, and was attracted by Lin Xi's transformation. The three of them intertwined a story of warmth and adventure on the boundary between modernity and immortality. The emotions are as delicate as silk, including the protection between brothers and sisters across life and death, the deep love between the male and female protagonists from temptation to trust, and the struggle and growth of mortals when they come into contact with immortality.
