I was taking a photo with my phone when I accidentally captured a naked woman. Strangely enough, when I tried to delete this "indecent" photo, I couldn't delete it no matter what I did! This undeletable photo opened the door to a mysterious, unknown world! And because of it, that naked woman became attached to me! After that, a series of terrifying events began to unfold around me! A thousand-year-old fox demon in the Longjing tea fields, ghostly apparitions in a house where an entire family was slaughtered, legends of a malevolent infant on a college campus, a mysterious pond that never runs dry, and terrifying rumors about a century-old forbidden zone... What exactly are ghosts? Why do some people fade into oblivion after death, while others become malevolent spirits or vengeful ghosts? Let's follow in the protagonist's footsteps as we step into the terrifying world hidden beneath modern civilization and uncover the truths behind the unsolved crimes happening right under our noses. Ghosts are indeed terrifying, but humans are even more so.
