Nan Qiao asked Houzi to investigate, and sure enough, it turned out to be Lu Zhengyang.
Nan Qiao explained everything about Lu Zhengyang to Grandpa Bai and Granny Bai, including Lu Zhengyang being involved with Chen Man.
Chi Chang and Chen Hesong came to Jing City solely because of Chen Man.
Grandpa Bai and Granny Bai did not meddle in Chen Xinwan's family matters and were unaware of this situation.
Nan Qiao said, "Lu Zhengyang is a man of dubious character, and Grandpa Lu doesn't even acknowledge his identity. I suspect that Grandpa Lu ended up this way because of Lu Zhengyang and his mother's doings."
Following Nan Qiao's analysis, Grandpa Bai and Granny Bai also began to suspect Grandpa Lu and Ren Yongshi.
"Grandpa and Grandma, I'll hire someone to investigate this matter. If it indeed turns out to be Lu Zhengyang and Ren Yongshi's doing, we'll definitely hand them over to the police."
As for Lu Tianlei, he's no good either.
