Zhou Ning glanced at the photo, and indeed, after enlarging it, he could examine it more carefully.
Overall, the wound resembled the shape of a wrench head, Zhou Ning looked again at the position of the victim's temple. If it were a wrench, then the linear damage at this position was clearly the arc-shaped trace of the wrench's side.
