"According to Master," said the God of the Underworld, "not only can the Bloodfiend dissolve, absorb, and assimilate any living being, but it can also absorb that being's strength, cultivation, memories, genes, Dao, supernatural powers, and special abilities—everything."
"However, as we and Master trained the Bloodfiend to its full potential, Master discovered a fatal flaw: once the Bloodfiend dissolved and assimilated a living being, it could not inherit their Dao, supernatural powers, or special abilities."
"Ever since discovering this inherent flaw, Master tried countless times to fix it, but every attempt failed. In his fury, Master killed the Bloodfiend."
