In the Divine Realm, as the upper limit of the Immortal Realm was breached and strength improved, it gave some martial artists confidence and naturally produced some thoughts.
In a certain Netherworld Cave within the Divine Realm, the original Netherworld Blood Children and Blood Disciples had all inexplicably vanished. They hadn't left the cave to return to the Netherworld; instead, they had been subject to Blood Refining!
At the center of the cave, there remained a dried-up blood pool, permeated with the Netherworld's bloody aura.
The martial artists who witnessed this scene thought themselves as Netherworld experts and didn't care too much about refining their subordinates' blood to enhance their strength.
One by one, the Netherworld Caves were subjected to Blood Refining. Although it drew the attention of some martial artists, they were merely cautious about the possibility of even stronger beings from the Netherworld descending, nothing more.
