wait, so magicians are able to still use mana even though theres no more giant? i re-read chapter 124 where mikel was talking to master about the source of where they got their mana from. so i thought he meant that they were looking for a replacement to continue using mana, otherwise they can't fight off the monster cause they have no more mana to use. but i'm wrong right? the tower only needed to replace the giant to continue the protective bubble that was placed around the empire but the magician themselves are still able to freely use mana on their own will. now that the protective bible is gone the only thing that changed is that demons are now more free to roam inside the empire more right? but the magicians can still fight the off. sorry, for my confusion x)
