Solving Cases Through Ghostly Whispers

[Mystery][Strong Local Flavor] Yan Chen was nearly hit and killed, only to be extorted by a ghost. In order to stay alive, he went to a teahouse open late at night to seek protection. Here, departing souls can have one final cup of tea before setting out for the Terrace of Looking Homeward. There are also ghosts burdened by obsessions who send over copper coins, write down their names, and ask him to resolve those obsessions. Listen to ghosts, solve bizarre cases. His senior advised him: [When you encounter a new ghost, don't let it realize that it is already dead.] [Don't believe what ghosts say. Ghosts are full of lies, clouding the eyes and disrupting the mind.] [Don't try to understand a ghost's logic, unless you want to become a ghost or want to turn into one.]
