The zombie was dead before it could move much.
There was no trace of joy on his face as he retrieved his blade from the head of the zombie and the wall. Flipping it, he cleaned the blood off and then scrutinized the edges of the blades.
The blade had chipped softly at a few parts of the knife. It was still very much usable but to Draziel, they were the same as imperfections that could hinder his combat ability.
He had meticulously calibrated his body to the size, shape and sharpness of the blade. If there were a few things changed, it would hinder his combat ability.
Although he was now a lot stronger than previously, which would render the calibrations he had made useless and unless he performed another calibration, his combat ability will never reach its full potential.
Which was why he had purposely repressed a bit of his strength during combat.
