Attack From Below

"We should be getting close, I remember this place!" Ellis said excitedly as they got close to a swamp. 

"Yeah, according to the map, if we continue heading in this direction, we would get there in about thirty minutes or so," Grey replied after looking at the map. 

He took a look at the swamp in front of them before shaking his head. 

"Unfortunately, we'll be going around it," Grey added. 

"Huh? Why? Going around would take at least another two hours," Ellis asked, confused.

"Did you go through here the last time?" Grey asked. 

"Yes, senior Zeke," Ellis nodded. 

"Hmm, it's because they didn't perceive you as a threat. Although I can't be sure they'll be able to sense me, I don't like taking unnecessary risks," Grey mumbled. 

"Who's they?" Ellis asked nervously. 

"Oh, there are two Overlord Plane beasts in this swamp. It's weird since they shouldn't be in this region," Grey replied nonchalantly.
