"Oh? Does it need to be done with multiple barriers? What about a barrier that can't be destroyed unless the caster runs out of mana?" I could not do this, or I would be outing myself to be someone with infinity mana, but this did not mean I could not ask the question. I was generally interested in what Sei would say to such a question.
"It's not that it can not be done but who in their right mind would put themselves at risk?" Sei countered with her own question. I could only give a dry laugh. I mean, I couldn't run out of mana, but that did not mean others couldn't.
"Okay, anyway, how does this inscription work anyway?" I decided to change the subject.
