CRACK! (1)
For Ryu, mastering the circulation patterns of the three Dao Charm techniques in his possession was easy, so easy, in fact, that Ryu felt that he was trying to learn Common Grade techniques all over again. But, the reality was that even Common Grade techniques he was familiar with had more complex circulation pathways than this.
Still, there was a sort of elegance in its simplicity. Ryu had already accepted that more complex didn't mean better. In fact, maybe some of the most powerful things in all of Existence were Fundamental Runes, the foundation of all that was.
Even without his eyes, Ryu still had the Origin Flame. Something like memorizing a circulation pattern was as easy as looking at it, it was the actual circulation that might take some practice. But, due to the simplicity of it all, even that came with a ridiculous amount of ease.
