Decisive Killing
Duncan felt clarity return to him as he watched the head of the Nine Yin Sect disciple roll on the ground.
The red haze that had enveloped his sight and mind seemed to recede back slowly as Duncan stared at the head. He could once more hear his surroundings clearly and feel the breeze on his face.
On his way back, Duncan fell into a strange state where his only thought was to kill the man who had fatally wounded him. Nothing else mattered to him at that moment. A sort of murderous rage enveloped his mind and he stayed in that state until the deed was done.
In that strange state, all his senses were very acute. They were heightened to levels he hadn't imagined before. He could see, hear, and feel far better than he was ever able to.
