Even with the effect of Ambrosia Aroma, Feng Luotian took a while to recover from his rumination. He had been racking his brain ever since he laid eyes upon the patients, trying to find other causes and possibilities of their symptoms.
However, after he finished searching his knowledge and memories, there was only one method that could strip the cultivation from a cultivator's body without damaging their soul core.
The soul core was the source of bloodline and Theríon.
The damaged soul core would result in the collapse of one's fortitude and configuration that required bloodline and Theríon to maintain its function.
The cultivators trained their bodies together with Theríon ever since their bloodline awakening.
The bodies would get stronger as their cultivation grew, then each muscle, bone, and marrow would require Theríon to flow through them like blood.
