(Don't bother, it's a terrible book) The Eighteen Levels of Hell
Lin Yifei wakes up in a crowd and looks around. "Huh? Are they filming something? Look at those qipaos and hanfu."
He's dead. He worked all night and died suddenly. This proves you shouldn't stay up all night, or your consciousness might transmigrate.
How would he know why he ended up here, or why he went to hell? He was just an office worker who kept getting overtime. How did he end up in hell?
A little ghost nearby shouts, "Why are you running? What's the rush? Going that fast because you can't wait to be reincarnated?"
All the ghosts: "??? Isn't that why we're here?"
But a few words from Granny Meng plant a seed of doubt in Lin Yifei's mind. Did he really die a normal death, or was he framed and sent here?
What is the underworld hiding? Or, for that matter, what is this world hiding?
The overall plot is pretty good.
