The first time I heard about the Annual Monster Wave it sounded like an apocalyptic event, but now after hearing from Ivan I'm sure this is an apocalyptic event.
The people of this world treat the wave of monsters the same way the people of my old world treated tornadoes or tsunamis, a force of nature that will happen whether you like it or not.
These people have been through this so many times that they have methods of defending themselves from it, now I understand how the master of the Adventurer's Guild Carlos, from the city of Valen which is in the Trigan Kingdom, was able to defend himself so quickly to the wave of monsters, he must have used plans he had already saved and people already knew what they had to do, this explains how he got so many potions so fast.
I look at Ivan before turning to Sapphire who has listened to this quietly.
