The qi that Ryu breathed into his body was incredibly pure. If it wasn't already enough that the Immortal Path was innately blemishless, even if it wasn't, his Ice Jade Crystal Bone structure wouldn't allow impurities to last very long. Due to this, Ryu didn't have to spend much time, if any at all, cleansing the energy he inhaled.
If one could see the inside of Ryu's meridians, they'd be absolute shocked. They'd assume he was an individual who had completed at least two Revolutions already, when the reality was that he had yet to complete even one. This was the difference between those with talent and those without.
Ryu worked quickly, after converting all of his Qi Fumes into a sort of primer energy for Mortal Qi, he begun circulating [Revolutions Amplifier] in earnest. The route was incredibly complex, even Ryu felt like his head was spinning, so he took the first cycle incredibly slowly, etching the pattern into his mind.
