Chu Mu lifted his head; he could no longer see the higher ocean regions. The blue scales obscured the view above his head, and various kinds of poisonous green liquids poured down from above the water.

"Young Master, there is one deeper down, but if we go any deeper, I'm sure the route to escape will be completely blocked!" Master Li said.
Chu Mu glanced at the deep fissure indicated by Master Li and vaguely discerned the flow of seawater into it.
If seawater could flow through this deep-sea trench, it meant there was a cavern below that led to another place. With this unexpected surprise, Chu Mu dove into the trench without hesitation.
