I Have an Omniscient Book

The Heavenly Dao of the Kaiyuan Realm collapsed, and demons from beyond the realm invaded. Humans, demons, the Demon Path, and the extraterrestrial demons formed a four-way balance of power. Chen Mo, carrying half a scroll of a blank Heavenly Book, transmigrated from Earth. He knew everything about the evolution of the Heavenly Dao. With this half-scroll of omniscience, Chen Mo embarked on a unique path of slaying demons and monsters. ... Many years later, having reached the pinnacle of the Dao, Chen Mo looked at the scroll in his hand and softly asked, "Book of the Heavenly Dao, in this world, who is the strongest?" Lines of golden inscriptions emerged from the Heavenly Book: "The omniscient and omnipotent one, Chen Mo."
