The man who came in was unremarkable in appearance, but his steps were slightly hurried. He walked up to the man coming down from the stairs and said, "Sir, we've found out about Mu Weijun's disappearance. His wife was shot dead, and their daughter is also missing.",It's unclear whether Mu Weijun is dead or alive. Mu Weijun is an orphan and we couldn't get a DNA test, but unexpectedly, they have a daughter.,So, if we find the little girl, we might be able to find the key。
