In the Demon Suppression Tower, after obtaining ample resources, Su Heng began the practice of the Dragon Shedding Blood Refining Method that he acquired from An Ran.
The fourth realm of cultivation, Blood Exchange.
The main development concentrated on the bone marrow, the essence of blood.
There are thirty-two vertebrae in the human spine. The Dragon Shedding Blood Refining Method has a total of eight levels, refining four vertebrae from the coccyx to the cervical vertebrate in ascending order for each level.
Once the thirty-two vertebrae are all cultivated, the whole spine will be like a mighty dragon, with power rising from the base and piercing the clouds. It will transform to an incredible realm, similar to a human-shaped ferocious dragon, with both strength and defense greatly enhanced.
Of course, this Cultivation Technique has its flaws.
