I Brought A Guard In Ancient Times

The next morning, the two men comb through the corpse, looking for signs of injury. They find that the wound on the left hand of the dead man is probably caused by the poison that yunjiangli poured on him that day. They also find that he was wearing an awkward left hand on the day of the attack. The two men decide to open the coffin and examine the wound. They notice that the wrist on the corpse is scarred. They conclude that the only person who could poison the body was yunpaizhi. They decide to look at the wound again, and see if the wound is still there. They discover that the scar is on the wrist of the man who was killed by yunphizhi, and they decide to examine it again.
