Barely Winning

Liu Feng looked intently at the result of the spell. This was a last ditch desperate attempt that he made because he didn't want to give up. He raised sword and stood on guard. He slowly stepped forward, covering the massive gap that was created between them. He was too depleted mentally to even fight anymore, but he had to make sure that the demon was dead, or it would literally be the death of him. 

After a slow, and painful advance, he finally approached an arm's distance from the demon. All around him, the mana was corrupted by the demon. He saw that the demon was laying on the floor. However, there was clearly a difference from before the fight and now. The mana did not roll on the body of the demon anymore. It was just present, that was all. The demon was immobile, but Liu Feng did not want to take any risks. He raised his sword and down it came. Liu Feng decapitated the demon. Only then did Liu Feng rest.
