Having bypassed the dense sea-fog that concealed the Sea People Manaklavi from afar, both Gu Shanhai and Black Horse actually breathed a sigh of relief.
Black Horse had considered running away on the road, but remembering the hunting mark that Gu Shanhai had placed on him and knowing that the other could strike from afar—even a single punch had left him flattened and had broken several of his teeth—the horse didn't want to gamble with his own life.
The boat could still sail without him; but without his life, he was nothing.
Lying on the boat, Gu Shanhai detected the creature's inner conflicts and hesitations. Unfortunately, his ability to probe thoughts was mere second level, not the fifth level that would allow deeper insight, so he could only grasp surface thoughts.
He was only able to understand so clearly thanks to his multitude of transcendent magic skills, which made his thought detection far exceed the capabilities of the second level.
