Gently stroking the remaining part of the lock, Wu Mian was a military weapons enthusiast. He had a fairly deep knowledge of weapons from ancient to modern times, so Xiao Lin felt he had found the right person. Despite searching for information on this kind of lock, due to its historical age or its insignificance, the descriptions in the materials were pitifully scarce.
"Xiao Lin, does this hold any significant meaning for you?" The two sat on a jutting rock by the North Palace, overlooking a corner of the central lake. Meanwhile, Wu Mian's subordinates were conducting a thorough, suffocating search of the North Palace, and a fire expert had also entered to assist in the work.
"To be honest with Director Wu, this lock might be related to a case I'm currently investigating."
"Aren't you and Qing Yi investigating Yao Zheng? Is there another case as well?"
"Yao Zheng is just the first move. I'm looking for the hand behind him."
