Shang Qinghua can be subtle if he knows what's going on and is prepared for it, which is absolutely not the case here on the Normal Boat. And he's so highly strung he might as well be a marionette. "I, ah, Iudex Neuvillette said that some people were seeing ghosts? In the world this one is from, at least, sometimes the dead leave behind... echoes of themselves, and if their death was traumatic, sometimes they leave resentful spirits, which seek to harm the living. Most cultivators have some training in dealing with resentful spirits--it is not this one's specialty, but he has some supplies against such eventualities, and as said, some small training! If there are no other experts in the matter available, this one might humbly offer his meagre skills? Though this one did meet a man who was the son of a death god, and so he might know more of how the ghosts or spirits are, and who they are drawn to, and why! This one would hate to be unprepared if resentful spirits were to attack."
