Nascent Soul Realm.

Under Blaze and Zier's astonished stares and thumping hearts, they witnessed Raven's Spiritual Essence spiking to exceptional levels.

Seeing this occur before them, they couldn't focus on their cultivation. 

It was unprecedented to see someone in the second stage of the Core Formation Realm advancing to the next stage in mere minutes!

Unfortunately, Ozul had to stop as he noticed the increasing unrest in Raven's body. 

He hadn't considered the fact that humans had different bodies than he did. 

While he only felt better as his strength increased, the humans struggled because their muscles began to strain. It would take some time for them to adjust to the sudden changes that had occurred within them.

Sighing silently, Ozul told Raven to stop. The latter, albeit reluctantly, followed his orders. As she stopped feeding her Core streams of Spiritual Essence, Ozul retracted the Purity from inside her body.
