The story begins with a shocking glimpse on an overtime night: when the fox demon Su Qinghuan failed to transform, human Lin Shen's blood accidentally repaired her Soul Bead. This fateful encounter leads to the human-monster war fifty years ago, the corrupt conspiracy in the fairy world, and the symbiosis experiment across the three realms. The author uses "golden crack" as the core image to turn trauma into a bond of connection - whether it is the birthmark on Lin Shen's wrist or the scar on Su Qinghuan's tail, they ultimately become proof of the power of symbiosis. When the rearview mirror of Lao Huang's hearse reflects the 1994 group photo, and when the photo wall of the deceased in Meng Po's live broadcast room flashes her mother's figure, those secrets buried by the years will eventually shine through different collisions.
