Through the translucent skin of the little monkey, one could see a colorless irregular pebble slowly rising and sinking within its golden half.
"Nascent Soul... Sarira..."
Wang Ba looked at this scene and slowly exhaled a breath of relief.
It was never a certainty that a Class IV Spirit Beast would form a Nascent Soul.
Some Spirit Beasts required an ample supply of Spiritual Energy to strengthen their physical bodies and thus would not form a Nascent Soul at Class IV. Instead, they would continue to nurture their Inner Core until reaching Class V, at which point they would transform their Inner Core directly into a Primordial Spirit.
Due to the Wu Monkey King's strong physical body and the practice of "Monkey God Nine Changes" and Xituo Continent's "Empty Element Nothingness" cultivation methods, it underwent the additional process of transforming the Inner Core into a Nascent Soul.
Essentially, there wasn't much of a difference.
