The system was aware of the current situation of Ibro, so he didn't delay as he injected huge amounts of demon energy into his soul sea.
This energy had revived Ibro again as he felt his strength returning to him at a rapid rate.
Ibro didn't wait for his strength to fully restore, as without the huge energy supply coming from his soul sea, these 11 cores were about to explode.
Ibro didn't delay anymore as he grabbed the swords with his imaginary huge hand and waved it towards all his surrounding enemies.
He injected the 11 cores at once into his hand and watched in anticipation for the result. Once the cores entered his hand, they miraculously disappeared.
Ibro smiled faintly, his plan had finally succeeded. His sword strike had caused an earth-shattering wave of energy that engulfed every demon in the whole region.
