Of Course There Is a Problem

In the end, no one was able to produce any results with the "branding".

Y'zaks' demonic bloodline rejected the lifeblood; none of the inoculations were possible. Vivian's Blood Clan lineage meant that she was immune to all foreign bloods. Nangong Wuyue and Ayesha, who were elemental species among the sirens also rejected the lifeblood. The substance only stayed a little while in their bodies. The others, like Lily showed neither acceptance nor rejection towards the lifeblood.

But, none of them could directly make the lifeblood vanish from their body like Hao Ren did.

"Looks like there must be devout faith and long-term spiritual training in order to make contact with the goddess." Big Beardy looked at Lily and shook his head. Then he turned to look at Hao Ren. "As far as you are concerned, I have no explanation for it. Maybe your God can give you the answer."
