In the multiverse structured by the Hongmeng system, the prehistoric world is nothing more than a "civilization experiment cabin" cultivated by high-dimensional observers.
Chaos Brood, Entropy Ruin Annihilation, Interstellar Cleansing Protocol... All the laws of heaven are cold data instructions. The ghost fairy is the only "out of control variable" in this experiment.
"Either become an observer, or destroy the observer - there is no third way."
——Wang Yixing, the last recursive body of ghosts and immortals
