Chaos: I Am the Heavenly Dao

Pangu created heaven and earth and all things, and the Heavenly Dao first came into being.

The protagonist, Wu Dao, accidentally transmigrates and becomes the Heavenly Dao. He thinks he can rule the world in peace, but discovers flaws in the universe. So he plots against Pangu, making him transform into heaven and earth, with his remnant soul becoming the Three Pure Ones and giving rise to the Pangu Clan.

From then on, Wu Dao uses his power for personal gain and protects his rule, becoming a villainous Heavenly Dao.
