With Jiang An's prompt, Zhang Yean's originally furrowed brows instantly relaxed.
She suddenly slapped her forehead, then smiled.
Then, Zhang Yean bent down, reached into the toolbox, carefully searched through a pile of tools, and quickly pulled out a pair of latex gloves, deftly putting them on.
As someone who has long worked in scene investigation, she naturally knew that for this important piece of evidence, it must be protected from contamination, avoiding her own skin cells and fingerprints from remaining on it.
Soon, Zhang Yean quickly walked over to Jiang An, taking the wooden stick from his hand.
Everyone's eyes quickly shifted like spotlights.
At this moment, the originally dark yard was brightly illuminated by lights, all lights precisely focusing on one spot, much like a spotlight on a stage.
Under the strong light, Zhang Yean slightly squinted her eyes, her gaze like a torch focused on one end of the wooden stick.
