It's easy to kill zombies. They are brainless. And everyone other than me are mages. So they can kill the zombies from distance without having to worry about getting bitten by the zombies.
Well, even I can fight from distance. So it was easy to kill the zombies.
Unfortunately, although zombies are weak against light magic to the point that light mages who turned into zombies can no longer use light magic, there's no way to restore the zombies back into humans. That is impossible.
Well, it's actually possible. It's just that one of the conditions for someone to be a zombie is death. So even if you turn a zombie back into a human, they will still die. So killing them is the easiest way to get rid of them.
Thanks to Angela and all the other earth mages in this place, this country is safe from zombies. Those zombies need to climb the wall so they can reach this place.
