Lin Xiuzhu, the Heavenly Emperor of the Human World, sacrificed himself to defy the unjust Heavenly Dao, falling into a deep slumber. Ten thousand years later, after countless reincarnations, he awakens without his memories. Born with poor talent, he is humiliated by his senior brother Wang Zian and betrayed by his fiancée. Worse, his mother is gravely injured while protecting him. In his grief, Lin Xiuzhu suddenly regains his ten thousand years of memories, marking the triumphant return of the Heavenly Emperor. He soon discovers the true mastermind—the Heavenly Dao itself, which has been draining the vitality of all realms. However, faced with Lin Xiuzhu, who now wields the combined power of the human race, the Heavenly Dao is ultimately defeated. At last, Lin Xiuzhu ascends as the Supreme Overlord of All Realms.
