Fang Mu felt there really was a possibility!
After all, the Blood Race was a kind of creature too.
But controlling the Blood Race through just a Destiny Guardian Beast was different from what Yisi had described as the Saint Heir of the Blood Race.
If one must make a direct comparison, one could say that the Blood of Abundance was the Saint Heir of the Blood Race!
But Fang Mu was not.
However, to verify this, he needed a drop of Covenant Blood Essence.
The fresh Covenant Blood Essence from the Blood of Abundance had just been used by Fang Mu on the Vicious Illusion Sparrow.
Fang Mu didn't have any Covenant Blood Essence ready to test on Yisi's Blood Emblem.
This made Fang Mu change tack, no longer limiting the topic to the Saint Heir of the Blood Race, but instead, he asked Yisi,
"I already have some understanding of the Blood Race's situation."
"What I need now is to understand the internal situation of the Blood Race more precisely through you."
