To avoid ending up like Bikamo, being pursued by Reiger or the Demonic Void, he didn't hesitate to burn everything below his eyes, offering the remaining negligible flesh as a blood sacrifice, leaving only enough of his brain to barely survive, using the gained power to summon abyssal creatures to block Reiger and the Demonic Void.
It doesn't need to be long, just a brief moment.
At the speed of an Abyss Demon Lord, having abandoned most of the body, only the brain remains; this time is enough for him to pass through the Abyss Gate, returning to the other side of the abyss.
He doesn't believe that the opponent dares to follow him into the abyss.
If that truly happens, he could accept his death as it is.
After all, he's using his life to lure the target into the abyss.
Once in the abyss, with the opponent's power, attempting to return easily would be impossible.
By then, many in the abyss would be after the opponent's life, and the Kings could attack without restraint.
