Black spirits are born from people's obsessions and can be attached to objects. People who get close to them will also be affected by them, hurting others and themselves. Although black spirits are evil, everything in the world can subdue them. Things that absorb the spiritual energy of heaven and earth can subdue black spirits. In the prime year of Kaiyuan, there was such a pottery xun made in the Stone Age, with a deep and ancient sound. Humans learned to make musical instruments in the Stone Age. During sacrifices, they communicated with heaven and earth through sound. This xun was buried deep in the mountain and absorbed the spiritual energy of heaven and earth. It can be used by people to drive them and break their obsessions and subjugate demons and resentments.
Purpose: Don't be too obsessed with life
