The two sides are in a fierce battle, enemies are endless.
The darkness and black threads seem to embody immortality, no matter how much the Two Camps try to supply, its existence, even if annihilated, would quickly resurrect from the darkness.
Simultaneously, in Lu Yuanming's Absolute Vision, he can see individual intelligent lives struggling and wailing within the threads, every second is unimaginable torture for them. Endless negativity emerges from these intelligent lives, then absorbed by the darkness... this darkness is consuming these negatives and using them as the foundation to sustain these lives' existence!
This is no longer a simple mutation; this is the great horror Lu Yuanming has never heard of!
He has experienced an eternal second, so naturally knows how terrifying it is for life to mutate due to negativity.
Mutation also has layers.
