After transmigrating to the Xuanhuang Continent, Xiao Chen became the disgraced Seventh Prince, banished to Canglan City by the Great Yan Dynasty. When he awoke, he was poisoned by Su Mochen, the Chancellor's son, while his beloved consort, Lin Qingwan, was forced to kill herself to preserve her honor. At the brink of life and death, the Invincible Emperor System activated automatically, bestowing upon him the highest cultivation art in all the heavens, the Heaven Emperor's Art. With countless Experience Pills, he broke through his limits in a single step and reached the second level of Qi Refining.
With the unwavering support of his three old subordinates, Wei Cang, Mu Wenyuan, and Shi Meng, Xiao Chen used the Heaven Emperor's Daoist heart to recruit peerless generals from throughout history, forge innate divine weapons, refine Nine-Turn Divine Pills, and steadily gather the fortune of the dynasty, using Canglan City as his base. He purged the Su family's traitors from the city, faced the invading army of the Beishuo Kingdom head-on, and gradually swallowed up the surrounding powers and small nations. From a castoff on the fringes of the Great Yan royal family, he broke through ten great realms of martial cultivation, ascended to the supreme Emperor Realm, swept across the myriad races and nations of the Xuanhuang Continent, overthrew the decaying old dynasty, and established an eternal central heavenly court of his own, becoming the one and only Heaven Emperor of Xuanhuang, who ruled over all creation.
