"Cultivation is the process of becoming terminally ill." In this world, the spiritual energy of heaven and earth is an active parasite called "Xuan Zhi". Cultivation of immortality is no longer about absorbing pure energy, but actively letting "mysterious evil" parasitize one's body, and guiding its "disease" in an orderly manner through cultivation methods, thereby gaining extraordinary power. Every breakthrough in realm is a more dangerous "exacerbation of the disease." Ascension is regarded as an "ultimate, irreversible and perfect diseased form".
