Honghuang: The Beginning of the Mythic Era

Reborn as one of the Five-Colored Human tribespeople at the end of the Human Emperor era, he witnessed the glory of the Age of Gods and Demons and the Human Emperor's apotheosis. He later took up the Three Sovereigns' cause, rose amid the darkness of an age of turmoil among gods and demons, witnessed the birth of immortals and demons, forged myths and legends, opened a new chapter for humanity, built the supreme Heavenly Court, and saw the war between the Wu and the Yao and Nüwa mending the sky, composing an immortal myth.

This is the story of a lowly human who rises step by step across the savage primordial world, battling heaven and earth, slaying gods, demons, and immortals, establishing the Dao, walking its path, and forging new paths. He roams the primordial chaos, suppresses countless eras, and stands at the end of the Great Dao.

P.S. This is a nonstandard primordial-world story built around the broad framework of the primordial genre and incorporating numerous myths and legends. If that's not your thing, proceed with caution.
