Corruption Protocol: Strange Resurrection

At midnight, there was a voice in my head. It's called "Corruption Protocol", and it calls itself the system. It issued me a task: hang a coat worn by a dead person in the corridor of the community, so that the "shadow" can be seen by four people. I thought it was just a weird game. Until I saw the thing in the coat at the end of the corridor - the shoulders were too broad, the neck was too long, and underneath the clothes was not a body, but a void darker than darkness. When it was one meter away from me, I knew three things: First, weirdness is real. Second, I am personally guiding them to the world. Third, the system is not helping me become stronger - it is turning me into a wedge to break the wall between reality and the void. But I can't stop.
