A higher-level five-fold Cultivation Realm nearby has been destroyed.
The destroyed five-fold Cultivation Realm is filled with Netherworld's Qi, with creatures from the Netherworld, and these Netherworld presences will seep outward.
When they seep here, this world's environment will start to gradually deteriorate.
The era of True Spirit extinction means that the cultivators in this world can no longer cultivate more powerful Profound Arts.
Now, with the seeping of Netherworld's Qi, the era of Heavenly Disaster is about to erupt.
The era of Heavenly Disaster is the world's backlash against the Netherworld's Qi, also the hell for ordinary people, the nightmare for cultivators...
As for the Celestial Demon, because it is soul-less, merely a result of Cause and Evil Thought, can it flow from one Cultivation Realm to another through the Sea of Suffering?
If so, the Sea of Suffering... doesn't exist only in one world.
