Try Sleeping in the Haunted House Tonight, Please Don't Disturb Me

In order to raise money for my seriously ill sister, I accepted a trial sleeping order for the S-class haunted house "Lijing Garden 2802". Rules written on the wall: Don't look back at midnight, don't answer the knock on the door… But I didn't expect that there were not only red-clothed ghosts in this building, but also a bottomless pit that could swallow up memories. My golden finger is to "listen to the memory of the deceased 3 seconds before death", but every time I use it, I will forget a part of my past. I am Lin Mo. Will I walk out of this building alive tonight?
