The Legend of Nuwa: Spirit Pearl 2

After the war between humans and demons, Shi Youming was eliminated, and the Vermilion Bird Divine Lord purged the demonic nature within himself and returned to the Celestial Realm. Bai Xi's spirit tablet returned to the Ninth Heaven, but the Goddess Nuwa erased all her memories of the mortal world.

Just as spiritual energy was being born, the miasma carried it into a rift between the Three Realms. Bai Xi saw an infant formed from the spiritual energy, wrapped in darkness and merging with the foul miasma. The spiritual energy was inherently good and pure; if it could not merge with the miasma, the two would become opposing extremes.
