Lu Xuan picked up the two objects and silently pondered their uses.
He knew that the Ten Headed Fierce Yang Serpent in Slaughter City would leave behind an Inner Core after its death. Likewise, powerful dragons could condense a Dragon Core when they passed away.
The round bead before him bore quite a resemblance to both in form and aura. It was very likely the legendary Inner Core of a demonic beast.
As for the object shaped like a brain, there was a very strong chance it was an External Soul Bone.
External Soul Bones came in all manner of bizarre forms, unconstrained by the shapes of flesh or bone. Their variety was astonishing!
They could be Eight Spider Lances, wings, tails, palms, or eyes. What was wrong with one being a brain?
With a rough conclusion in mind, Lu Xuan could not help feeling lighter at heart.
He fed a strand of soul power into the brain-shaped object. A moment later, he confirmed it beyond doubt: this was indeed an External Soul Bone.
More remarkable still, it possessed both spiritual and spatial attributes!
Worth it!
This single External Soul Bone was enough to make up for all his experiments over the past several days. None of the Soul Bones he had consumed earlier had gone to waste.
"Lingling." Only now did Lu Xuan find the time to seek out Ye Lingling, his voice carrying a note of delight. "My research paid off. I finally cracked the Azure Jade Bird's secret."
"Congratulations, Brother Lu Xuan!" Ye Lingling's eyes curved into crescents, genuinely happy for him. She smiled and said, "Now you can become even stronger!"
"Yes, I'm going to grow stronger again. Then I'll be even better able to protect you." Lu Xuan picked up the peculiar External Soul Bone
