Lin Fan and Loli finally got a clue from Zheng Yang, a clue that is likely related to An Jincheng's disappearance.
Unfortunately, Zheng Yang did not know about the friend that An Jincheng mentioned to him years ago.
Lin Fan was worried that Zheng Yang might have missed something, so he asked again carefully, only to finally confirm that there was nothing useful to be found from Zheng Yang.
"Teacher Zheng, thank you so much for your cooperation." Lin Fan said with a smile.
Zheng Yang sighed and said, "Jin City has been missing for so many years, I often think of it and feel it's a pity. I hope you can find him."
Lin Fan said, "We will do our best."
Loli still felt a bit upset with Zheng Yang because years ago Zheng Yang concealed such an important clue. Although Zheng Yang claimed it was to avoid trouble and not affect his elderly father who had no one to care for him, she, as a police officer, found it hard to accept such a situation.
