Four-and-a-half-year-old cutie Pao Pao falls from the sky, crashing into the Abyss Dragon Palace, and immediately calls the ruthless Black Dragon Emperor Ao Yuan 'Father'. Carrying a small conch bag on her back and a mini ink-spraying octopus on her head, she tames a fierce beast with a bowl of sweet porridge, and a pinky-swear instantly melts the Emperor's frozen heart. Yet during the blood-recognition test for kinship, the awakening dragon crystal shows no reaction at all—whose child is she really? And why does she carry the dual bloodlines of both the Heavenly Realm and the Abyss?
