[Alchemy Manual: Fluoroantimonic Acid]
I have watched a video before when I was a human in Japan, about this acid.
That acid was the strongest acid in the world. And yet, he managed to invent it. Then, he gave me a box as he said,
"This is the crafted result of this acid. Good thing that it was containable in the plastic ammo."
Plastic ammo? Well... It sounds like a toy gun. But let me try it.
"Stay there, Reili. You're pregnant. Go with me, Albedo."
"I have to follow you, Kuso," Reili remarked strongly which, it had made me choose the stern word to her.
"This is the dangerous experiment. Single blunder could backfire and kills anyone nearby."
"But that... It was the magic right?" Reili looked at me in a worried look as she asked me that. Thus, I explained to her.
