"If Pure Yangzi could devour his own kind to raise his realm, then given a Heavenly Demon's nature, he would probably have long since eaten all the countless billions of Heavenly Demons!"
"In that case, even if he could not enter the Eighth Dao Realm, he could at least advance to the peak of the seventh rank, comparable to a Heavenly Immortal. If the Heavenly Immortals guarding the gates of heaven and earth did not return, who in the Immortal Realm could oppose him? Earth Immortals like us might perhaps still escape with our lives, but all other living beings beneath the heavens—even Human Immortals—would be swallowed in a single bite."
"Once he had consumed every living being in the universe, his cultivation and strength would likely rise to an unimaginable level. He might even become stronger than the progenitor of the Heavenly Demons! By then, not only Earth Immortals like us—even Heavenly Immortals would be eaten one by one..."
"The subsequent course of events also confirmed our suspicions. Pure Yangzi swallowed only part of the ocean of demonic source and three seventh-rank Heavenly Demons, yet his power already showed signs of losing control. He could no longer swallow a fourth Great Heavenly Demon!"
When Fairy Yuquan and the other five Earth Immortals saw the Great Heavenly Demon Pure Yangzi absorb the origin of demonic baleful intent and devour seventh-rank Heavenly Demons, causing his strength and realm to surge without cease, they had initially been greatly alarmed as well.
Later, they discovered that Pure Yangzi had ultimately failed to advance into the late seventh rank. Moreover, as time passed, his wildly increased cultivation was gradually draining away. They concluded that he had cultivated some secret Heavenly Demon art, allowing him to forcibly contain the origin power of other Heavenly Demons.
