Mutation Failed?
Although the Black Turtle bloodline had the ability to balance his blood, it also meant that it had increased the strength of his bloodline multiple times over.
While this was, indeed, a very beneficial thing when considering the final outcome, it might also cause a higher chance of failure, if Hei Gou could not handle the sheer amount of energy that it infused into the mutation.
Hei Gou was not born with the sovereign bloodline. To him, this was a foreign treasure that could rouse his own bloodline's potential and cause it to mutate which would bring him to a higher state, however, it was, after all, a foreign treasure.
Unlike Xue Wei, who was the owner of this energy, Hei Gou was not, and he would not gain any help from his body or bloodline, so he would have to face this potent energy on his own.
The area had descended into silence. Xue Wei and the others kept their eyes on Hei Gou, worried that they might miss something important, but the black dog did not react.
