When natives of the Divine Path World slew false gods, because no outsiders were involved, Guan Ling lacked an anchor through which to permeate her power. Thus, she had no way to reclaim the immortal corpse fragments that appeared after a false god perished!
These immortal corpse fragments would then fall into the hands of other false gods, making their power ever stronger.
For example, Ear Wisdom God had originally been nothing more than an ear bone from the corpse of the Nine Heavens Mysterious Maiden. Over tens of thousands of years, its followers had continuously hunted false gods like Long-Eared God, those related to hearing and ear consciousness, gradually piecing together the entire left ear. This had brought its "divinity" and authority to the very pinnacle; its strength even surpassed that of Martial Might God, whom Shen Mo had fought bitterly for a long time before finally killing.
For Guan Ling, this had both advantages and disadvantages.
The advantage was that the slaughter and annexation among false gods could gather a great many tiny immortal corpse fragments in one place.
At the beginning, a single left ear of the Nine Heavens Mysterious Maiden might have spawned tens of thousands of false gods, large and small. Killing a weak false god like Long-Eared God would at most reclaim a piece of flesh the size of an earlobe; some would yield only a drop of blood or a shred of skin. But now, Ear Wisdom God had nearly assembled the entire left ear. As long as this false god was killed, a large immortal corpse fragment could be reclaimed.
Guan Ling might not even need to intervene. After the Divine Path World developed for a million, or several million, years, it was entirely possible that a sole false god would emerge.
