Huangfu Jianchen nodded, "Because the C5 pistol is used for illegal purposes, it's hard to find on the market unless you go to the black market exchange."
"That's great, let's head to the black market exchange now. Although it happened two years ago, they should have a record of every transaction. We can start by finding out who bought the pistol and then trace our way back to the hidden murderer."
"Mi Yao, the black market exchange is a mixed bag, even if they know something, they won't tell you because there's a rule against disclosing buyer information."
"What should we do then?"
"I have a little brother who hangs out there. Just wait, and I'll have some information for you in three days."
"Third Prince, thank you in advance."
"It's no trouble at all."
The two searched the room for a while longer but found nothing further, so they decided to leave.
"Mi Yao, where are you headed now?"
Mi Yao thought for a moment, "I want to go… to the Divine Doctor Hua."
"What for?"
