24-Year-old Lin Ye was sent to Qingshan Mental Hospital due to severe depression. He thought he would spend the rest of his life in chaos and drugs, but one midnight, he bumped into a "special" patient——
He never eats or drinks, his eyes are completely black, and anything he touches becomes moldy and distorted inexplicably, and even photos cannot capture his face. All the patients kept secret about him, and the medical staff pretended not to see him, as if he was a "taboo" in this hospital.
Since then, Lin Ye's life has been shrouded in strangeness: the patient next door disappeared mysteriously, and the surveillance screen was swallowed by black mist; the walls seeped with fishy black water, and inhuman whispers came from the middle of the night; the crazy old Mr. Chen chanted "black eyes, faceless, don't look back", and there was a cold secret hidden under the dean's gentle smile.
When Lin Ye discovered that this mental hospital was not a rehabilitation center at all, but a cage built for "it" by past guardians, and that the patients' fear and madness were the nourishment of the seal, the fingertips of the ink-eyed patient had been gently pressed against his forehead——
"He's almost awake."
The ancient syllables entered his mind, and Lin Ye saw the bloody runes, wriggling tentacles, and his own shadow being assimilated underground.
What he picked up was not a patient, but an old body that was about to tear apart the seal. And he himself has already become the most perfect "container" for the evil god.
On the edge of sanity and madness, Lin Ye must choose: become a sacrifice for the seal, or live in symbiosis with the evil god, and uncover the ultimate truth about chaos and humanity behind this cage?
