Cheng-Jing [成精]
Chéngjīng; Henge; Tsukumogami
Cheng-Jing are animals, objects, or even abstract concepts that have attained a level of qi cultivation that allows them to take on the appearance of a human or near-human entity. As a result of moving outside of their place in the universe, they often possess semi-divine powers of immortaility and healing.
