I decided to try acting dumb, "I have no idea what you're talking about."
Fuckface smirked at me, "Do you think I will not recognise a summon when I see one? I've spent half my life researching them! I know them better than anyone else does!"
I blinked at him, "Wait… Do you mean those Shadow Devourers are Shadow Summons? But they drop Mana Crystals when you kill them?"
Wait… Oh… I think I can guess what he's doing…
"Ha ha! That is my crowning achievement!" He boasted proudly. "Look at you, you're only able to call out one Shadow Summon at a time, right? But I'm able to create an army of them on my own! That's what I have achieved that no other Umbramancers could!"
"Hmm… I see… Instead of just using your own magic to summon a Shadow Summon… You're making use of Liquid Mana and a corpse to anchor the summon physically by turning them into pseudo monsters, am I right?" I asked.
