But all of this Grey did not seem to be aware of as he wholly concentrated on reading the Shadow sect secret art.
Actually to be able to learn this art, one must have great perception and control over the corrosive substance within their body. Everyone knew that was impossible since the corrosive substance left behind by God was invasive and hard to deal with, but they were some special people who had a certain amount of control over their shadows.
The first step in learning this art was guiding the corrosive substance from one's body into their shadow.
'This art seems to be tailor made for me already! All the corrosive substance within my body is already fully absorbed by my shadow, so it means I can go on to the next stage.'
The second stage involved filling the outline of ones Shadow with spirit energy. Once you've done that, you can begin to mold your Shadow into any shape with the spirit energy acting as the flesh and the corrosive substance acting as blood.
