Meilan, Mashiyuan, Old Dog, and Red Ghost were swimming through a natural sewer in the underground level.
Old Dog could swim underwater with Meilan and Mashiyuan for a long time with just one breath. Red Ghost's body and appearance had changed somewhat; fish scales had grown over his body and face, allowing him to breathe underwater. He swam much faster than the other three.

"No. And I'm not fighting
