Even if Yu Ming knew all the fish demons in his clan, it was not easy to find the one in Xue Mingyu's story. That was because almost all the demons in his clan had such characters, and that was why he couldn't immediately guess which demon had abandoned Xue Mingyu and his mother.
That was why Yu Ming gave no response and continued to frown at the younger demon. Maybe Xue Mingyu read that look as a sign of him continuing his story, but he didn't say anything either. It might not be easy to read what was in the King's mind, but the room was plunged into silence for a while as the two of them did not continue talking.
The silence was only broken when Yu Ming opened his mouth to ask, "After gathering more information about him, did you try to find him?"
