Sebastian was trapped, trapped inside a cage that he created.
He was now blind, breathing was difficult inside the cage of rocks that he formed himself, and his face was a bloodily mangled mess.
Not only these, but his health points were also now 12 and were still decreasing slowly. His Megalodon bloodline was doing a good job in suppressing the effects of the Devouring Cobra's poison, but it could not be expelled completely.
The Devouring Cobra was also a creature of a high-ranked bloodline. Just as terrifying as the jaws of the Megalodon, so also was its poison.
Sebastian's bloodline suppressed the damaging effects of the poison to the barest minimum, but that was all that it could do, the poison was still spreading and slowly killing his life force.
With only 12 health points left, Sebastian was stranded. It only needed a matter of time before he was drained completely.
