After Dijiang put away that drop of Ancestor Witch essence blood, he bowed to Zhang Qing and said, "Many thanks, Daoist Friend. There is just one thing I do not understand, and I hope Daoist Friend will enlighten me."
Zhang Qing raised a hand, gesturing for Dijiang to speak. "Why did Houtu abandon her identity as an Ancestor Witch and transform into the Netherworld Underworld? Is there some reason behind this?"
With a blank expression, Zhang Qing said, "Earlier, the Ancestor Witch Hall was closed, ignoring the calamities befalling the Primordial World Human Clan, and many Wu Clan members even perished tragically. Their surviving souls flew into the Sea of Blood, wailing all day long. Ancestor Witch Houtu found them pitiful and thus transformed into the Netherworld Underworld, giving those pitiful souls a place to rely upon and enter Samsara."
