Xiao Wujiu carefully examined it several times and found that it was nothing more than an utterly ordinary Spirit Bone. He could only shake his head helplessly.
"The conditions for an External Soul Bone to form should not simply be that it is not one of the six major body Spirit Bones. There should be other reasons I do not know about."
"I was biased from the start. I assumed that any wings produced would definitely be an External Soul Bone. Or perhaps these 'External Soul Bones' beyond the six major body Spirit Bones are merely another kind of Spirit Bone."
After putting the Spirit Bone back into his Storage Ring, he planned to find a few more soul beasts and try the same method, to see whether the resulting Spirit Bones would remain the same. That would let him roughly determine whether it was a matter of probability or bloodline purity.
Afterward, from Amethyst Crystal Bears to Man Faced Demon Spiders, from Fierce Eagles to Ghost Tigers, none of the External Soul Bones they produced possessed that kind of "growth potential." Even after absorption, they could only be treated as ordinary Spirit Bones.
