Chapter 796: Who Would You Protect

Xie Qiao thought it would take at least ten days to half a month for the people to investigate the case. That would be considered fast…

"This case is easy to investigate," Xie Pinggang said straightforwardly. "Fortunately, she used the silver ring powder. Otherwise, it would indeed take some time.

"The silver ring powder is not available locally. Only foreign merchants would bring this medicine or medicinal herbs to make it. Lingnan is far away, and there are not many merchants from there. You can find it by asking around. Moreover, this kind of thing is sold at the black market. If you manage to catch one person from there, you will be able to find the source of the goods. Yesterday, I spent the entire day and searched around. I found a tea merchant, but this kind of big merchant has a family behind them..." 

If they followed the clues, they would find even more relevant people.

With more people, the case would develop smoothly.
