When Lin Yu opened his eyes in the mental hospital bed, he thought he was crazy - those blue light monsters that could swallow shadows and the gluttonous cubs with seven eyes were clearly seen with his own eyes, but they were regarded as evidence of paranoia.
It wasn't until he broke into the basement where glass jars and iron chains were hidden late at night that he was shocked to realize the truth about this hospice hospital: seventy-two soul-suppressing nails were buried under the century-old soul-suppressing barrier; doctors in white coats held bronze daggers, and gunshot scars were hidden in their hospital gowns; all those diagnosed as "mad" could see the cracks between the real world and the alien space.
There is no shadow of the woman in the red nurse uniform. The old woman in the laundry room always hears the cry in the washing machine. Crazy Zhao's crazy words are all predictions of death. What Lin Yu didn't know was that the power of the soul suppressor flowed in his blood, and he had already been stared at by eyes deep in the seam.
When the blood moon climbed into the sky, the monster in the iron cage broke the railing, and the blue shadow reflected his horrified face - should he pick up the dagger engraved with spells, or become a sacrifice swallowed by the shadow? In this game played out in a mental hospital, there was never an option of "recovery and discharge".
