"!!!" The dog and the chimera widened their eyes in shock. Strength was leaving their bodies. The sharp pain felt like they were being stabbed by numerous blades. Their souls were torn apart.
They were confused as to how they even got all this pain for a second before they remembered Theo was in front of them.
In that instant, they realized the pain actually came from Theo's power. And everything was just an illusion, so they had to release their own power to stop the influence.
But the moment they did it, Theo appeared in front of them. He was still using the Embodiment with his Death Avatar.
Just like Rea, who managed to gain the strength of the mythical creatures, Theo also could use the Death Avatar's power aside from the four authorities. Though, it was more like Theo's original ability he came up with.
