I Was the Only One Who Could See the Second Body at the Murder Scene.

Cheng Yan is the cleaner of the haunted house and the son of the criminal who committed the arson seven years ago. His father's relic wakes up at the scene of the first murder, allowing him to see a stranger who will die in 24 hours. Every time a person is rescued, a piece of erased evidence of the fire can be recovered. When all the notices pointed to Dongling Mall, he decided to recover his father's innocence before the next death.
