Guan Yun traveled to a terrifying and dark alien world full of "weirdness" called "Xiyuan Realm".
This is a world where the physical constants are similar to those of the earth, but filled with a basic energy called "Ling Qi".
Lingqi is the source of life and the foundation of all supernatural powers.
However, the scary thing about this world is that after the death of a living being, its consciousness completely dissipates, but the spiritual energy that constitutes the origin of the soul will not be annihilated immediately.
Most of the spiritual energy will slowly and steadily disperse back to heaven and earth.
And for those creatures who die in extreme pain, fear, resentment, unwillingness, or strong obsessions, their dissipated spiritual energy will carry these strong negative emotional imprints and fragmented consciousness fragments.
These "polluted" spiritual energies cannot return to nature smoothly, and will accumulate, distort, and deteriorate under specific circumstances. Over a long period of time, these polluted spirits gathered and devoured each other, absorbed environmental energy, and gradually formed a terrifying existence that was neither alive nor dead, without complete consciousness but driven by some kind of instinct or obsession - "weird".
As a scientist, Guan Yun used his own way to adapt to the world, but he gradually discovered that the problems in this world were not just weird!
