In the physics theory of his previous life, shadows were an optical phenomenon where light was blocked by objects and projected onto the surface, forming the outline of a bright and dark boundary.
In theory, the shadows of ordinary objects were no different from the shadows of humans.
It was not corporeal and could not be used as a parallel mind carrier.
However, this was the cultivation world. There was spiritual qi circulating in everything. No matter what they encountered, they could not be too "superstitious in materialism".
In this world, the appearance of humans was originally created by Nüwa to imitate the images of the gods in the world, secretly conforming to the Dao here.
Although the shadow only had an outline, it was still in human form.
Jiang Li's shadow had followed him for many years as he cultivated and meditated. It was nourished by the dense spiritual qi of heaven and earth in his surroundings.
