Li Qingchen transmigrates into a fantasy cultivation world and uses his Cleanliness System to gain one overpowered advantage after another. From the moment he is born, he unlocks the Supreme Chaos Physique and secures his position as the Divine Son of the ancient Li Family. Thinking he can simply enjoy an easy life, he never expects to transmigrate again, this time to 100,000 years in the past. There, he becomes the Divine Son of the Divine Dao Sect, dominates the ages, and gathers prodigies from every corner as his loyal followers. By the time he falls and returns to his original era, his cultivation has become unfathomably powerful, leaving even the greatest geniuses of his generation unable to catch a glimpse of his back. And the most outrageous part? When the ancient emperors awaken in the world, every single one of them bows respectfully and calls him Big Brother.
