"I think this is some giant monster that came here from somewhere else, settled down, and accidentally blocked the river. I've seen similar things before," Amy said with a serious expression, withdrawing her hand from the light greenish meat wall.
"All right, then what about the fog and the strange behaviour of nearby animals and monsters, who crazily attack anyone who enters the fog?" Myne found Amy's explanation reasonable, but it deepened some of his doubts. After all, most giant monsters are solitary creatures and don't like other creatures in their territory, especially right under their noses, let alone using them to attack others.
