The Yin Sha Blood Corpses were a type of Yin Yang Devil Corpses recorded in the Corpse Refining Technique that Han Li obtained from Qian the devil. Although the actual refining formula was not included, it was mentioned that despite their immense power, the process of refining these corpses was excessively malevolent. It was said that the corpses used for refining must share the same bloodline as the refiner, as this was the only way to use the power of kinship to suppress the backlash from the Blood Corpses.
During the refinement process, the soul of the corpse's owner would be trapped within the body forever, unable to reincarnate.
Although cultivators generally do not hold kinship as dearly as ordinary mortals do, such tainted and cold-blooded acts still were not committed by many. Strangely enough, even those ruthless cultivators who did refine such Blood Corpses met with extremely miserable fates, with none able to live out their natural lifespan.
