"Is that so? Then I will assign you a task, but this task requires your utmost attention. Once you discover anything, report to me immediately, and remember, never touch any potential clues."
Seeing Zhang Xiaobei about to assign him a task, the police officer immediately perked up.
"Alright, Mr. Zhang, just tell me what I should do?"
"Do you see these weeds on the ground?" Zhang Xiaobei pointed at the weeds on the ground and said.
"I see them. What's with these weeds? Could we possibly find the killer through these weeds?" the police officer asked.
"No, how could we possibly find the killer through these weeds? If it were that simple, we wouldn't have failed to solve the case for so long. What I mean is for you to pay attention to your feet, whether it's weeds, rocks, or even the soil, to see if there is any trace of blood on them?"
