After dinner, Master Qian asked Lu Jiaxin what she wanted him to do. Gu Wenfeng had told him that Lu Jiaxin needed help with something, but didn't specify what it was. Mainly because Gu Wenfeng himself wasn't clear, so naturally, he couldn't tell him.
"Come in with me."
Once they were in the study, Lu Jiaxin asked, "Do you know anyone in the Forty-nine City?"
"I know quite a few people. What kind of help are you looking for?"
Lu Jiaxin didn't hide it from him and said, "I need to investigate Ding Jing and her family. Ding Jing is the woman my dad married later, and also my best friend from high school, Kang Tongtong, and her family."
Gu Wenfeng had informed Master Qian about Lu Jiaxin's family situation. Investigating a stepmother and her family was understandable, but looking into a high school friend was out of the ordinary: "What did your classmate do to tick you off?"
