As he does your daughter, now bored with the demoness, turns back and runs over to you and jumping up into your arms. “This 'Rimuru', as I've heard named, seems to be conquering kingdom after kingdom, through military force and through diplomacy both. With the goal of conquering the entire continent, turning it into a monster-exclusive domain for him to rule over.”
“You've heard? Through rumors?” you ask, Ainz somehow, despite being only bone, gives you a wry look. “Ah, I see. Demiurge?”
“Yes, along with Solution, Sebas, and Shalltear. He is taking the lead, Sebas, Shalltear, and Solution going undercover as a foreign noble and her butlers.” Ainz confirms, yet his tone isn't confident. “They've yet to travel inland enough to make contact with this “Great Jura Alliance” or the “Demon Lord Rimuru” themselves yet, however Demiurge has uncovered some interesting information already.”
“Oh?” you ask, knowing it has to be good for the Overlord Ainz to get that glowing look in his eye “Did you find a weakness?”
“Mayhaps. Demiurge has discovered that this rising Demon Lord is actually a slime.” he says, grinning like he's already won the fight. But he sees your blank expression, his own smile fading a bit. “Ah, I forgot. Despite your power and knowledge, you are still young. Slimes aren't common here in this environment, your not encountering them is not that surprising. While more commonly known as a common, low-level threats in most settings, they are dangerous foes to most people. Slimes can dissolve anything that enters their malleable, gelatinous body, devouring it and absorbing it to the cell. Some can even gain the abilities of those they eat, gaining their powers and special skills.”
“Wait, they devour things by just absorbing them?” you ask, shocked as the skeleton nods solemnly and remembering what Towa'd shown you of Majin Buu after nearly being absorbed by that Time Patroller yourself. “That's horrifying. Is there any way to counter it?”
“Poison resistances are always a start, along with some manner of Frost Armor as the slime race have a damage vulnerability to Cold.” Ainz replies instantly. “However, that is for normal slimes. I haven't heard of a Demon Lord falling to a slime before, but for it to take one it must not only be powerful but extremely intelligent. A Demon Lord is, usually, a being on an ascended plane of magical or physical power.”
