Jiang Xing was born into a world of immortal cultivation and spent eighteen years waiting for a cultivation simulation system to arrive, only to discover that he had no spiritual roots and was nearing the end of his lifespan. An unexpected stroke of fortune granted him dual water and wood spiritual roots through the accumulated virtue of his fellow villagers, setting him on the path to immortality. Using simulations to scout the way and choose rewards, he struggles to survive amid absurdity and danger. In Guangwu City, he rescues his long-lost younger sister, Jiang Ranqiu, counters the Crown Prince's schemes, and joins the Longevity Garden of the Dao Sect. During an assignment outside the sect, he discovers the Hehuan Sect's atrocities against ordinary people. Using a simulation token, he infiltrates the demonic sect and navigates its dangers by exploiting theatrical costume-making, becoming entangled in a love-hate relationship with the Holy Maiden, Ji Qinxin. After returning from the destruction of a sect, he remains a Foundation Establishment cultivator investigating a corpse-disappearance case and demonic conspiracies, employing flexible tactics while steadfastly holding to his principles.
