Because the Soul Seed had shown resistance previously, the Blood Demon had already prepared to use certain methods to forcibly suppress the Soul Seed during the fusion process, in order to complete the fusion and obtain its strength and gains.
However, to his surprise, the process of fusing the Soul Seed went very smoothly without any resistance. The only thing that puzzled him was why the Soul Seed seemed to be taking root in the Divine Soul?
It gave him the impression that although the Soul Seed had merged, it had not dissipated; instead, it coexisted with the main soul in some way.
Vaguely, the Blood Demon felt something was amiss, but he could not discern the reason for his unease.
As the Soul Seed fused, those mysterious runes also entered into the Divine Soul. The great techniques cultivated by the Soul Seed were not manifested as expected.
