I’ve read the light novel, but I can’t recall how Kazuma’s party gets through the barrier on the demon king’s castle, and the wiki isn’t updated that far into the series.
I know Wiz maintains the barrier, but I can’t remember if Megumin brought it down with explosion or if they told Wiz to bring it down.
Thank you. I remember the mana crystals, but I couldn’t remember if that was just to destroy the armies or also to take down the barrier.
