Wang Hai carefully helped grandma to the sofa. After her mood had stabilized a bit, he continued, "The boss received this message this morning because it was from an unknown number, so he asked me to investigate the source." At this point, Wang Hai paused, looked at Xia Lian, and continued, "The boss has always valued our lady very much, so he doesn't take anything concerning her lightly. I traced this number to its original owner and found that the person had no connection to the lady and claimed they hadn't used the number in a long time. I then continued my investigation and ultimately traced it back to Miss Cheng."
Cheng Shishi tensed up and uneasily shrank behind Xia Lian. She hadn't expected to be found out so quickly; she thought she had been discreet. The phone was bought from the second-hand market, and the number was purchased from a card vendor. No information relating to her was left behind. How did they find out so quickly?
