The story unfolds in a primordial, chaotic continent, a barren land that eventually gave birth to the Heavenly Dao, creating the Hong Meng Myriad Worlds. This universe is divided into Upper, Middle, and Lower Planes. The Upper Plane is supreme, home to countless powerful beings who forge endless laws and govern myriad galaxies. From the dawn of time, two supreme forces emerged in the Upper Plane, rivaling the Heavenly Dao: the Hong Meng Immortal Realm and the Chaotic Demonic Realm. These eternal enemies have waged a death struggle for millions of eons, drenching galaxies in blood and causing immense suffering, yet neither has triumphed. The Demon Emperor Hua Mojian has a genius son, Hua Tianshang, born with the Nine Heavens Divine Dragon Physique, possessing unparalleled talent and destined for invincibility. He is the strongest among the Demon Emperor's five children. Despite his peak demonic power, Hua Tianshang lacks military leadership. His father sends him to the Human Realm's Tianwu Continent, where he must build his own power as a direct descendant of the Marquis of Sword Dynasty, with ninety percent of his demonic power sealed. It is then that a new sect, the Cangdi Sect, rises on the Tianwu Continent, shaking the world.
