I was in a car accident delivering food and woke up with a heart that was not my own beating in my chest.
The doctor said the donor was a homeless man, but I didn't think much about it and kept running.
Until that night, I walked into an old community - everyone in the corridor was dead. A tongueless woman in red was wandering in the darkness. I heard her counting: "One... Two... Three..."
On the wall next to him, there was a line of words floating in blood: No talking is allowed here.
No one told me that this world has long been infiltrated by "ghosts". They unfold their ghost realms, lay down the rules, and play with interlopers like a cat and a mouse. Want to survive? You can sacrifice your body parts - eyes, arms, legs, and ask the ghost to spare them.
But they don't know that the sacrifice is the light in their darkness, and the darkness in the light, and the darkness can kill everyone.
Of the seven billion people in the world, only one person came back alive from the Ghost Realm - he sacrificed a pair of legs and then went crazy. The authorities were helpless and could only cover up the truth and pray that the ghost would leave on its own.
