Thirty seconds, a mere instant to kill a robust man, shows that the killer is a professional assassin, or at least a habitual offender.
"If it's not the cause of death, then what was he doing holding the victim's neck?" Ran Yan murmured to herself.
Following that, she reached out to touch the corpse's head, switched her scalpel for a larger one, and deftly shaved off a piece of hair from the center of the scalp.
With the hair no longer obstructing the view, the weakest spot on the body was exposed, revealing a mung bean-sized blood spot, distinctly visible. Ran Yan felt a surge of excitement. She used the tip of her knife to pry open the congealed blood clot and cut a small piece of skin attached to the skull, finally discovering traces of metal.
"Inspector Liu, please look, this is the cause of death," Ran Yan said as she used the scalpel to clear the surrounding obstructions, presenting the faintly revealed metal to the two of them.
