Aldrian unleashed a slash that covered the entire battlefield—a strike he named Slash of the Vanguard, as it would pave the way for his own series of sword techniques. After developing a few techniques, he realized he needed to arrange them in a specific order. The Slash of the Vanguard would serve as the opening strike in his yet-unnamed series of sword movements, and ending with The Slash of the End—just as he envisioned.
However, at this moment, the Slash of the Vanguard proved to be devastating for the devil army, as this single attack alone could bring about their end. Once Aldrian completed his slash, the arc of energy stretched across his entire line of sight, traveling at more than three times the speed of sound. The swing of his blade sliced through the air itself, cutting it before reaching the charging devils army who attempted to advance toward him.
