Elena was pulled out of the cube because Mykel was awake after she blasted him with her life energy. The life energy that lingered around Mykel's body slowly being repelled by the abyss that made him immune to it.
It didn't take a few seconds until Mykel recovered as if nothing had happened to him. That made everyone nervous, and when Luciel used the [Fracture] skill to weaken him, the inside of the cube started to crack. It was supposed to make Mykel weak because the space inside the cube had been cracked and ripped into pieces.
They were fooled and he made them believe that his power could only devour and not the other way around. He could turn the abyss and make it impenetrable by anything, not only that, it could repel anything that tried to get in.
"Playtime is over," Mykel said as he spread his wings and shattered the cube and the space around him.
