The Fourth Form of Saber Truth: Destiny Blade was altogether different from the three preceding forms that were equipped with both offensive and defensive flows; it was impeccably flawless with a menacing edge. This two-styled form was a technique that was purely intended to execute the ultimate kill!
It was definitely a world-ranked assassin's ultimate attack - with unlimited possibilities and ways to deal death.
Wind Beyond The Sky was the paramount technique of an executioner, crafted from scratch; this particular move was aimed towards single opponents, for it was full of unexpected surprises - it would be almost impossible to defend against.
Nonetheless, this was not an entirely flawless technique. To activate this move, one had to concentrate the mystical energy in his entire being, then discharge it in a quick burst. This was the drawback; after executing the move, a lot of mystical Qi would be expended, regardless of whether the target was hit or not.
