Vassal
Jason was really interested to find out if it was possible for him to cultivate with multiple energies too.
For now, this was impossible because his very first attempt to absorb primordial energy had almost damaged his cultivation vein.
But now that the seals on his Celestia bloodline were trembling violently, seemingly trying to unleash something that was locked from him, Jason realised that it was not unlikely for his secondary or tertiary bloodline awakening to transform his cultivation vein too.
This was not something he could be sure about, but it wouldn't make sense for humans to be able to cultivate in several paths at once, only for him, the descendant of a Celestia, to be unable to do the same.
However, there was also the possibility that the Celestia race were simply beings unparalleled in the field of Maest and control over mana!
