Zhang Yi had to wait for a few hours while the two of them finished asking all the witnesses, Li Tang was used to doing that and so did her job faster.
But Du Chen did his job more slowly and unwillingly because he realized that Zhang Yi wasn't doing the same job as them and was just standing near the two dead warriors, what Du Chen was seeing was that Zhang Yi was leaving all the work to them and doing nothing.
Zhang Yi could not imagine that Du Chen thought this of him and just waited patiently for the two to finish chasing the killers, in a while, the two came to report on the witnesses.
"Did you get anything, Mr. Du?"
"No, by my side nobody seemed to know anything, it seems that whoever killed these two did it fast."
"And you miss Li?"
