Kapitel 1871: "Carpenter Guy" 

Even if the lake didn't look big at first sight, the depth could not be explored at the moment, so if the lake did have an unreachable depth, it would make sense to have various behemoths hiding inside. 

Everyone had exchanged the information they had in their hands and now, the group brainstormed to complete their missions which actually overlapped with each other. 

The carpenter guy and the sonic attack guy, who were not as active as the cheetah man and the gentle glasses man, finally spoke up some of their own ideas. 

The first to raise his hand was the sonic attack guy. 

"My ability is some kind of sound wave. It's different from the usual sound wave, so maybe we can try to probe the depth of the lake with my sonic attack?" 

Ainsley's 3D map ability also relied on her sound wave, but that sound wave could not be classified as an offensive attack.
