Thus, this technique was made based on that concept. In this technique the user creates an aura of Yin around their weapon. While concentrating a significant amount of Yin energy into a small area, which is the sharp part of the blade. The key is in the compression and concentration of Yin. When a great amount of Yin is concentrated and compressed like that, it would most likely have a "very" high Yang absorption rate. In other words, the blade would absorb the Yang of anything it touches instantly. Meaning that it could penetrate through everything and anything. It can even penetrate through substances that are deemed to be unbreakable as it eats the physical energy instantly.
