If this attack was successful there would be nothing that could change the outcome. Olcan will die!.
First the demon energy surrounding the snake would act like corrosive and begin eating up his internal organs, secondly the poison would immediately spread throughout his chest and stop him from breathing and his heart from beating. Even if Elara appeared right on time to push out the demon energy from his body, He would die without a doubt from snake poisoning.
Unsurprisingly this was the expectations of the girl, most of her prey ten millenniums ago died like this so she expected nothing different with Olcan. Even Olcan had no different assumption.
He saw the snake launching at him with it's fangs ready to sink into his chest but he couldn't prevent it, it was too fast and too close. At the last second before the snake got to his chest everything turned to slow mode in his eyes, he could see his life flash before his eyes.
