Duncan never stayed in one place. He moved from one place to another. One moment, he would be in front of the cannibal attacking its thigh, the next moment he would disappear and reappear behind it and slash its back. Duncan's relentless assault made the cannibal unable to mount any comeback. It tried desperately to protect its vitals with its remaining arm.
However all its efforts were moot, as once Duncan incapacitated its other arm, he truly went in for the kill without pausing to even give the cannibal a breather. Duncan appeared behind the cannibal and swung his sword in a savage manner, not holding back even an ounce of his strength, aiming for the back of its neck.
The cannibal's instincts screamed at him to duck and move, but it was too late. The cannibal had already lost a lot of blood from the several wounds Duncan had inflicted upon it. Its both arms were incapacitated and its entire body was in a world of pain.
