If this boy has no core and no sign of proper mana control, then that means... The barrier's detection system perceived him as a threat! His uncontrolled energy interacted with the barrier's coding, creating an outward flux of positive and negative energy.
Bourne carefully pieced together what had happened.
Not only did the boy use his own energy to counteract the barrier's output, but his control was flawless. He had managed to stop the destruction of his surroundings, something that seemed impossible considering the immense power involved.
If even a single particle had slipped through his control, it would have resulted in devastating consequences.
Examining the destroyed entrance with his mana vision, Bourne was amazed by the perfect symmetry outlining the gates.
