I was patrolling around the town, specifically the part to which I was assigned. I have to find out if any monsters broke through the defences using the underground as a way to enter the town.
It was a common method for monsters to use such a way.
Normally people see that monsters belong to three categories based on their living habitats. They are Land Monsters, Flying Monsters and Sea Monsters.
These three are how monsters are broadly classified but what most people forget about are the underground monsters. Many think that the Flying Monsters or the Sea Monsters are the most dangerous ones but that is wrong.
Underground monsters are the most dangerous of all.
The sea is home to a lot of monsters and in the deep sea, it was said that there are a lot of dangerous monsters. There was a rumor that in the deep sea, Tier-9 monsters are common as if you see commoners in a nation.
