The Slumber Mist seems mystical, but its ability only causes temporary out-of-body experiences.
If taken outside, it would just make someone drowsy for a while.
But the Yin Emperor's Tomb beneath Muyuan Community transforms at night into a 'magnet' targeting souls. All soul or ghost-like ethereal beings feel drawn to an unknown place within the tomb.
The difference is that souls are attracted without realizing it, while ghosts can slightly resist.
To many, ghosts and souls are considered to be the same.
But actually, they are quite different.
The essence of a creature is imprinted on its soul; possessing a soul makes a being intelligent, without which it is merely a walking corpse. High-level superpower users' souls carry the source of their strength.
Generally, souls can't be interfered with through normal means, nor can they interfere with reality. Only those with special abilities can see souls.
