Single Bound
Ryu sat in silence for a long while. Deducing exactly what had happened was difficult, but now that he had a general understanding of the process, his deduction path was far clearer than it had been before and he slowly began to feel some real clarity.
The Blood Tempering Realm was a bit unique in that it focused entirely on one's blood, but it was also simultaneously the Realm that the Pulse and Vessel Tempering Realm had been building up to.
The strength of one's body came almost entirely from one's blood. Bone Structure could play a strong or small role in this strength depending on which you had been born with, but obviously for Ryu, it was the latter. His Ice Jade Crystal Bone Structure was definitely not known for its strength.
