Blood-Bone Knife

Han Sen looked in the direction that Son of Fate's gaze had stiffened, and noticed it was Zero who he had seen. She had emerged from the Tree King and was now approaching them.

Zero had already returned to her human form, but her hands held a red knife.

The knife was around a foot long, and it was completely red. It had skeletal characteristics, and its color made it look like a bone that had been soaked in blood.

Han Sen frowned, unsure why Son of Fate would be so scared upon seeing Zero.

"Impossible! Impossible!" Son of Fate was screaming like a madman, and he looked horrified.

Han Sen looked at him, ready to tell him to shut up, but before he could, a red flash cut across his vision. When his eyes steadied their focus, he saw the blood-bone knife lodge itself in Son of Fate's heart.
