So, when the light spell went off like crazy, he played dumb about it, probably to avoid drawing attention to himself. But now he shows up with a still-frozen bear he oneshot with ice magic?
Feel like he's pretty dumb if he's trying to not draw attention to himself. He shouldn't even really be thinking the typical dumb isekai MC "oh no, I thought this was normal!!" thing either, because he just had a conversation with god about how unreasonable his power is.
