Actually, Meng Sushan didn't learn much about things.
However, she had seen many familiar faces at those gatherings.
After she told Xia Xibei about these things, Xia Xibei used these people as clues and dug them down layer by layer.
Before that, although they wanted to find out the industry behind He Xuan, it was very difficult.
They could not find a breakthrough. The man who was caught before said a lot of things about He Xuan, but he didn't know much about the situation in Hua.
He Xuan also couldn't imagine that Meng Sushan would be an undercover agent sent by Xia Xibei. What was more unexpected was that those things that Fang Xinzhen showed off in front of Meng Sushan would become the key to a breakthrough!
After there was a breakthrough, things were much easier.
Qiao Yanjue found out after sending someone to follow these people that there were many things involved with them.
