Ten minutes later, Director Hou, Chen Guan, Jiang An, and Qin Feng together delivered the trace evidence extracted from the ceiling panel to the evidence laboratory.
At this moment, the young officer Zhang, who was on duty in the evidence laboratory, was holding a pipette and wearing a mask.
He initially thought it was a routine submission for inspection.
Unexpectedly, when he opened the laboratory's glass door, he suddenly saw Mr. Chen and Director Hou among them.
He quickly removed his mask and said, "Mr. Chen, Director Hou."
"Are you here for an inspection?"
"I'll call our lab director over right away!"
"No, no, it's just normal evidence, no need to be so nervous."
Vice Director Chen waved his hand and said, "Zhang, it's just ordinary evidence, no need to bother the director. He's getting old, and it's quite tiring for him at night, let him rest."
"But with both of you leaders here, I think it would be more prudent to call him over."
