Qi cultivation emphasized spirit roots; body refinement also emphasized spirit roots.
The Barbarian Race and Witch Race were exceptions.
The Barbarian Race and Witch Race drove Killing Intent into their bones, tempering their skeletons and marrow, seeping outward into flesh, blood, and skin, and inward into the Five Viscera and Six Bowels. It was an ancient body-refining method that took bones as its foundation and blood as its function.
Bones as the foundation, blood as the function.
Thus, bone aptitude and bloodline were the standards by which the Barbarian Race and Witch Race judged body-refining talent.
At seven years old, one's bone aptitude took shape. The bones became mature and stable, and children's teeth underwent their second growth. This was precisely when the Barbarian Race began physical-body baptisms, awakened bone aptitude, and set foot on the path of body cultivators.
When he was seven, the Tuoba Tribe tested the bone aptitude of all its children.
Tuoba Yuan stepped forward and dripped his blood for the test.
The elder said expressionlessly, "Tuoba Yuan, bloodline grade—Yellow Grade. Body-refining aptitude—inferior."
Little Tuoba Yuan's face turned ashen.
Barbarian bloodlines were divided into four grades: Heaven, Earth, Black, and Yellow. Yellow Grade was the lowest, with limited potential. Even though Barbarians were naturally physically powerful and brimming with vital blood, no matter how hard one with the lowest Yellow Grade bloodline worked, they could only become a Golden Core body cultivator.
A Golden Core body cultivator sounded far from weak, but this was the Nine Heavens and Ten Earths. This was a second-rate Barbarian tribe with an Integrated Body Barbarian Venerable standing guard.
If this had been the resource-starved, Sealing Heaven and Locking Earth Nine Provinces Continent, a Yellow Grade bloodline would have been no different from a Pseudo Spirit Root. Achieving Body Foundation Establishment
