The thoughts of the God above Gods are truly unfathomable, before, the so-called rules were merely conjectures made by the deities based on past events, Aeo never personally admitted what the standards for deification are.
Perhaps, this God above Gods really saw something special in Amberser and wanted to see him create miracles again.
End the Blood Battle?
Something that even all gods could not do, could he truly accomplish it?
The demons of the Endless Abyss are of the Chaotic Evil Faction, they cannot be influenced by "reason" or "benefit," unable to eradicate that destructive desire, the Blood Battle will never cease.
The God of Alchemy couldn't understand how Amberser planned to do it, but He was not in a hurry, after all, Amberser no longer had a lifespan problem, so why not take it slow. The Blood Battle has been fought for so many years, a thousand or so more wouldn't make much of a difference.
