While it might seem as though Antonio was dealing with less attack on his side, to protect Sebastian, he had to release the protective barrier around him and focus only on Sebastian.
Sebastian shut his eyes closed for a few seconds and when he opened them, his former black eyes turned full white, leaving no space in it.
"Don't worry brother," Sebastian mumbled, he let go of the black mirror he was holding on to and grabbed the two-blue glasses which was hovering in the air, behind him. And without having any second thought, he threw one of the balls at the black mirror.
Immediately as the blue ball came in touch with the mirror, a loud explosive sound rang out in the surrounding, followed by the black mirror shooting out a beam of black light.
Though the black beam of light shot out fast, if one was able to take a good look at it, one would be able to see thousands of thunder and lightning particles coiling around it.
