Magnus was reincarnated in a magic world. He led a simple life on Earth and that was something he liked rather than being dragged into conflicts or into adventures to save the world or something like that. He never cared to be the MC but hoped that he would have a pleasant life, much better than his previous life. Whether he could or not, read the tales to see. ---
During the monster tide, there would be a lot of damage to the place where it happened. It is not something that can be changed unless someone can stop the monster tide before it happens.
No one has such power.
Even though there are powerhouses who can stop smaller monster tides, it would be underneath them to even think about those small monster tides.
In the kingdom, there would be a lot of monster tides happening from time to time. Most of them are considered small monster tides. This was not because they are actually small but the highest monster would not cross Tier-3 in those tides.
Sometimes there would be a Tier-4 mixed in that but unless there is more than one Tier-4 monster, it would be classified as a small monster tide.
