The primordial era began with the mythological age.

Reborn into the Five-Colored Human Race at the end of the Human Emperor's era, they witnessed the glory of the God-Demon Age and the Human Emperor's transformation into a Daoist being. Inheriting the ambitions of the Three Sovereigns, they rose to prominence in the dark age of God-Demon turmoil, witnessing the three races establish their Dao and vie for supremacy, the birth of immortals and demons, creating myths and legends, opening a new chapter in the human way, building an unparalleled Heavenly Court, witnessing the struggle between the Witch and the Demon, Nuwa mending the sky, and composing an immortal myth.
This is the story of a humble human race that rises step by step on the fierce and desolate land, fighting against heaven and earth, slaying gods, demons, and immortals, establishing, practicing, and pioneering the Dao, traversing chaos, suppressing countless eras, and standing at the end of the Great Dao.
P.S.: This is an atypical prehistoric story with a prehistoric fantasy genre as its main framework, incorporating many myths and legends. If you don't like this genre, please proceed with caution.
