"I can't. The sea monsters around here are mostly high-ranking monsters, while I can only confuse the middle-ranking sea monsters." 

In other words, they couldn't use the sea monsters to attack the island…

The marshal furrowed his eyebrows as he commented. 

"Really? I thought the monsters here were mostly middle-ranking. The one's attacking us are all middle-ranking sea monsters."

"Marshal, sea monsters are more intelligent than the land or the flying-type monsters. Maybe because the miasma concentration isn't that bad in the ocean." 

The woman paused before continuing. 

"These sea monsters won't blindly attack humans unless they're attacked first. The sea beasts are also like that." 

The woman recalled what she read in a book about sea monsters and beasts. She couldn't help but gulp nervously.
