Abel's sword was extremely precise. Although he had only used 2 light swords, he had unleashed a great deal of damage to those 2 head commanders.
The light sword plunged into the open mouths of those head commanders and penetrated their bones, chopped off their airway and archeries. With a little pick, the blade then entered the skull of those head commanders.
Abel did not want to expose his combat qi, so he just added a strand of power of the will to his sword. After the sword stabbed into their brains, Abel's power of the will gave it a quick scan.
Abel had 240 points of power of the will, and this head Commander had 24 points, which was quite good already. With this difference, this little scan had directly melted their brains into mush,
Life faded from their gaze as Abel retracted his light sword. Their body jiggled and fell off their horse.
