Their bodies made them inherently sensitive to the presence of a devouring lily cauldron phantom spider—even with its stellar camouflaging abilities. In addition, those with predominant yin physiques often possessed powerful souls, allowing them to use their soul essence to injure the spider, even while it remained in its incorporeal form. To the devouring lily cauldron phantom spider, they were a lethal threat—far more dangerous than those with yang or fire-based physiques.
This was why, no matter how delectable they might be, the spider would rather risk parasitizing a host with a yang or fire-based physique than dare to target someone with a yin-based one. The risks were simply too high—especially if the target possessed a highly potent yin physique. In such cases, it was likely to turn from predator to prey, easily.
