A few moments right when the walls of dark flames and darkness barrier had just been erected, Blake materialized the new ball of darkness that he just got, the one from Cyra's evolved bloodline ability, and sent it backward.
Moving it slowly and covertly along with the dark flame walls, masking it with the huge presence of the dark flame walls.
The muscular humanoid demon, the one that Blake tried to keep inside by erecting those two barriers, was currently trying to hit Cyra's head with his fist, something that he wasn't able to achieve since Cyra could simply phase through the wall of dark flame and hide behind it.
And for someone who had a taste of how vicious those flames were, there was no other better deterrence for the muscular humanoid demon other than a towering wall of dark flames, one that was even taller than himself.
