I believe that the "Piercing Technique" (also translatable as "Wave Explosion") is a class of techniques that are defined as the 'techniques that bypass the opponents defences'. This particular effect has been associated with the unique nature of the technique Jinsung taught to Baam, which is an effect attributed to combining the Flow Control with the Reverse Flow Control in order to deal damage to the target.

It's never easy to determine which technique is the precursor; assuming any of the known techniques is actually a precursor for the others. It's possible that each of these techniques is simply a different twist on the "Piercing Technique" / "Wave Explosion", and there is no other relation.

Show/Hide Spoiler That said, the technique Baam uses in 219, is almost definitely based on the Floral Butterfly Piercing Technique given its visualisation and even its name. Moreover, given the grand effect of this variation, we can probably assume it's an advanced variation of the FBPT.
