Just with this Primordial Yin swimming in his body, Ryu felt that he was able to strip himself of all impurities. No part of his body was capable of escaping this, not his soul, not his Meridians, not even his Spiritual Foundation.
Just by virtue of cultivating, Ryu would be able to constantly allow this Primordial Yin to swallow up any impurities that he gathered into the future.
This shouldn't be underestimated. That was because also by virtue of cultivating, he would be gathering impurities onto his body.
He had thought that just by using Spiritual Herbs and 100% Pure Pills he could avoid this, but he realized after his interaction with Wobbling Fairy that his concept of Impurities was far too lax and incomplete.
The reality was that there were impurities even in the air he breathed. Every time he gathered qi from his Meridians, there would be more that swarmed in from the Chaos Plane. Every time he improved his soul, there would be more.
