"You will die today!" The middle one barked out as he rushed toward Don with a red sword billowing outward with life energy.
A dangerous glare could be seen in Don's eyes while he circulated as much as battle energy he could and this struggle against the dark energy had already damaged his various organs. Using the battle energy, the black Sword instantly became a black strip of light and shot toward the fourth middle one's head with a sonic boom like sound.
It was as if the sword had broken the sound barrier. Flying through the air and leaving behind after images of itself, nearly no one could see it clearly due to its speed and the dark and gloominess of the storm.
