"The murder weapon?" Xiao Yun lifted her head to the side, "What's wrong with the murder weapon didn't someone stole it?"
"It was a trap that I made. Instead of waiting for the traitor to show up, it was easier to lay them a trap. The murder weapon was in truth a fake one. After receiving the autopsy from the forensic of the corpses's wounds, I identify the weapon and design a knife similar to the one that was possibility use to kill. I gambled. If the traitor believes he didn't forget the murder weapon, the plan would fail but fortunately he thought the murder weapon was his and came to retrieve the weapon."
Xiao Yun was astonished by his plan, she smiled, "But how would you be able to find the traitor?"
"I placed a track to see where the murder weapon would appear to. At whose house or whose building."
"And is it Tang Guanyu?" asked Xiao Yun for her to see Wang Li Lei nod. "What will you do now?"
