"Swish!"
Ning Daoran raised his hand and extracted the Demon Core, which was also the Dragon Ball, from Old Dragon's skull.
After taking the Dragon Ball, it emitted a warmth. Upon closer observation, he noticed the surface texture was extremely exquisite, resembling warm jade. It contained an immensely terrifying essence qi - half of Old Dragon's life's essence was probably contained within this Dragon Ball.
"It truly is a Divinity Transformation Stage Dragon Ball..."
Ning Daoran frowned slightly, feeling pity that there was a minor flaw in the Dragon Ball, having a slightly cloudy appearance. It was a manifestation of the Old Dragon's fall from Divinity Transformation Stage to Nascent Soul Stage.
Thus, this Dragon Ball could only be considered a subpar one.
Nevertheless, it was still quite impressive and worth keeping for potential future use.
