Eric kept in touch with Xu Cheng for a very simple reason; he wanted to know more about Ruan Zeyan and Ling Tianya.
However, after spending quite some time with Xu Cheng, he realized that the woman knew virtually nothing about what was happening in the Ruan Family, and she knew very little about Ruan Zeyan and Ling Tianya.
Xu Cheng had originally lived in City S, where she had no contact with the Ruan Family. She had only come to this city and settled down recently.
Since he couldn't get anything information about Ruan Zeyan out of this woman, Eric decided to stop wasting time on her. Xu Cheng wasn't a very beautiful woman. If she had the looks of Ling Tianya, he might have been willing to spend some more time with her.
Just like that, after a short period when Xu Cheng thought things were going well, she completely lost contact with Eric. She tried to contact him, but he never picked up the phone again.
