The Divine Realm, as the upper limit of the Immortal Realm was unlocked and strength enhanced, gave some Martial Artists the confidence, naturally leading to the sprouting of certain ideas.
In a Netherworld Cave within the Divine Realm, the Netherworld Blood Children and Blood Disciples that originally occupied the Heavenly Grotto had all disappeared, not having exited the Grotto to return to the Netherworld, but were refined through Blood Refining!
At the central location within the Heavenly Grotto, there remained a dried-up Blood Pool, pervading with the blood qi of the Netherworld.
The Martial Artists who witnessed this scene, who considered themselves as powerful beings of the Netherworld, were not particularly concerned about the slaughter of their subordinates to enhance their strength through Blood Refining.
