"DON'T DO IT!" Horus shouted in rage and hatred as he flashed toward the dark temple, terror emerging in his heart as he contemplated Cain's next move.
The Scarlet King only smiled as he glanced at the mutated body of the Void King, now an artifact of the Depravita Race. He couldn't care less about the suffering of the Dark King, and his eyes glowed with desire and killing intent as he flashed forward and stretched his hand toward the Ancient Key.
As soon as Cain got near the Ancient Key, it emanated a monstrous psychic force and energy barrier, but he burned what little was left of his life force and pierced all of them, finally placing his hand over the mutated body.
No dimensional storage in Aether could hold an Ancient Key for more than a few seconds, but Cain had one in his soul that had already proved worthy of the challenge. The next second, the Void King vanished, appearing inside the [Grand Demonic Devourer Dimension], next to the Blood God.
