True Meaning of Heart of Killing

Duncan crashed through the walls and rolled a little bit before coming to a halt.

Duncan groaned in pain as he stood up and wiped some blood that leaked out of his mouth. The young man he was facing currently was really strong. Duncan was no match for him regardless of how he tried.

After clashing countless times with the young man, it became clear to Duncan that he wasn't going to injure the young man any further. That single drop of blood that spilled was the only thing Duncan was able to obtain until now. After that, it has continuously been his blood that was spilled.

The young man had wizened up to Duncan's strategy of aiming for the same location pretty quickly. Ever since then, every blow the young man had delivered was like a mountain smashing into him.
