The world is sliding into an abyss. Incomprehensible and indestructible "Shadows" - ghosts who follow cold rules of killing - resurrect around the world, tearing everyday life into desperate nightmares. Yang Yun, a supposedly ordinary young man, encountered his first mysterious shadow in the morgue of a funeral home late at night. With an almost cold sense of reason and a trace of luck, he paid the heavy price of having his body eroded by the shadow, and became a "ghost controller" struggling on the edge of life and death.
To harness the power of shadow is to embrace the curse. Every time he used that cold shadow ability, Yang Yun's body became more alienated and his emotions became more indifferent. He walks on the boundary between humans and ghosts, struggling to survive amidst the intrigues of the official organization's "Special Strategy Bureau", the intrigues of private ghost controllers, and the endless life-threatening supernatural events. From the "Silent Hill Community" that swallows sounds, to the "Ghost Tram" that wanders in the gap between time and space, to the "Ghost Post Office" and "Guixu Ancient City" that hide endless horrors, Yang Yun discerns the rules in despair, deals with ghosts and people's hearts with wisdom, and exchanges a heavy price for a glimmer of life.
When the global supernatural power is completely out of control and the shadow of ancient existence envelopes the earth, Yang Yun's body that has been eaten away by the mysterious shadow will face the ultimate choice: Should he become a patch and delay the end, or fall into the abyss and become a new terror? "Bone Cage" is a regular horror novel that is cold to the core and thrilling in wit. It tells the story of how a mortal gradually transforms into an inhuman thing in a desperate world where evil spirits resurrect, and searches for the almost non-existent glimmer of light in the eternal darkness.
