The merman, a humanoid creature with a large fish tail, wide pelvic fins, black scales covering his waist and abdomen, and ear fins instead of human ears. His wrists are pierced by iron chains fastened to iron rings on the ground. He has been brutally tortured with whip marks from abdomen to tail. He can speak but his voice is hoarse and rough after being silent for a long time. He is weak, emaciated, and has lost hope of living, secretly pleading for death. He bit Zhang Jingzhu's wrist in self-defense out of fear.
