Lin Xuan was originally a handyman in the outer sect of the Qingyun Sect in the Cangxuan Continent. Because he had a secret Taoist body, he was jealous of his fiancée Liu Ruyan and the sect's genius Zhao Wuji. He was abandoned in his cultivation, his meridians were cut off, and he was abandoned at the bottom of the Immortal Burial Cliff. When he was on the verge of death, he awakened the [Emperor of All Realms Devouring System] and gained the ability to devour all things to strengthen himself. After devouring the thousand-year-old poisonous dragon and the remains of ancient monks at the bottom of the cliff, his injuries healed, and his cultivation soared to the golden elixir stage. After returning to the sect, Lin Xuan beheaded Zhao Wuji and devoured his luck in cultivation. When he rescued the sect's saint Su Qingyue, he triggered the [Emperor's Harem Tiandao Lock], making her the first imperial concubine to give up her life. He relied on his devouring ability to sweep through the Qingyun Sect, devouring enemies and seizing the treasure trove to establish himself as the sect leader. In the early stage, his harem absorbed descendants of Yaoxian Valley, girls from the Nine-tailed Fox Clan, etc., And began to take shape. As his strength increased, the scope of Lin Xuan's conquest expanded to the Cangxuan Continent and all the worlds, devouring the blood of powerful enemies such as the ancient gods, abyss demon commanders, and ancient dragons, condensing the body of the Chaos Emperor of Ten Thousand Paths, activating the [Ten Thousand Paths Summoning] function of the system, and mythological figures such as Chang'e and Jiutian Xuannv came to pledge their allegiance. The harem grew into an army of top women from all races of immortals, demons, gods, and monsters. However, the overbearing devouring caused the most powerful people in the world (the ancient emperor, the demon god of chaos, the lord of darkness) to encircle and suppress him, treating him as an anomaly. The final battle broke out at the top of the world. Lin Xuan devoured thousands of avenues to smelt the origin of heaven, suppressed all opponents and ascended to the position of [Ten Thousand Ways Emperor], established an eternal divine dynasty to rule the three thousand worlds, and three thousand emperors and concubines divided the heavenly palace to share eternal power with them.
