My Paper-Making Shop Connects Yin and Yang

[Suspense + Supernatural + Folklore Horror + Rules and Weird Stories + Modern Mysteries] Before my grandfather disappeared mysteriously, he only left me three strange rules: [The door must be opened at midnight, and the incense cannot be cut off] [Closes on time at midnight, no living persons allowed] [For nighttime customers, we will respond to their requests] I thought this was just a boring life running a shabby paper shop, until that night—— A woman in white clothes with an earthy smell knocked on the door and handed over a wad of banknotes stained with grave soil: "Boss, buy a can of milk powder." Only then did I realize that the paper ingots burned on the shelf for the dead souls had turned into real objects in her hands. From that day on, Train No. 44, Headless Girl, Bus No. 122... Those entities that only exist in ghost stories began to knock on my shop door frequently. I dug out a yellowed account book under the cashier counter, filled with names of "customers" I had never seen before. On the last page, there is my grandfather's signature, and there is a line of small words next to it: "Grandson, if you see this page, it means they... Have found you."
