Zarek's expression was graver than ever before.
He knew he didn't have many options left.
Alexander's strength was no longer something he could handle with his physical body alone.
He had to undergo spirit transformation!
Only after spirit transformation could he hope to match Alexander's strength with his enhanced body and find an opportunity to kill him with magic!
However, he was well aware of the side effects of spirit transformation.
Once he chose to transform, the spirit beast essence within his body would be rapidly consumed, which meant his lifespan would be shortened.
It was precisely because of this side effect that no Devourer was willing to undergo spirit transformation unless it was a matter of life and death.
But now, Zarek had no choice.
He raised his left hand, placed his wrist near his mouth, and bit down hard.
Blood spurted from the artery in his wrist.
