'Interesting…'
Ryu spun the jade on his finger, his mind churning. His thoughts shifted from the overview of the technique, down to where the pitfalls might be.
The first and most obvious was in the method to fuse Spiritual Quintessence and qi. Unfortunately for the Martial Gods, the secrets of the Three Souls and Seven Spirits was already revealed to Ryu, so he knew what was written down here was a large pile of nonsense.
It spoke about taking Spiritual Quintessence, pouring it into your surroundings in a sphere, forming it and molding it, before trying to "cultivate" it through the nose and mouth as though it was normal qi.
Trying to do such a thing would be asking for minor fractures to accumulate along your soul over long periods of time.
