Lin Yuan is just a food delivery boy.
After working for two years, I know 360 streets and alleys by heart, and my five-star rating ranks among the top three on the site. His most valuable possession is an ancestral copper bell on his ankle - grandma said it was to ward off evil spirits, but he never believed it.
Until that rainy night, he took an order of brown sugar glutinous rice cake. The address is "Morgue, B1, 444 Hades Road", with eight words of note: Eat it while it's hot, don't let it get cold.
The navigation led him to a clinic that had been abandoned for seven years. The stairs extended downward endlessly, and the afterimages of faceless riders wandered in the corridor. The takeout order on the wall had turned yellow, but the words on it were exactly the same as the one on his phone.
The bell rang seven times. He followed the bell and sent Ciba to the negative floor. Forty-seven minutes later, he came out alive.
The average survival time for ordinary people after entering is four minutes.
An organization called "Filter" came to visit. They told him: the city was being eaten away by alien spirits. They are not ghosts, they are rules condensed by human obsessions - if you step on the wrong step, you will be transported to another time and space, your reflection in the mirror smiles at you but you haven't smiled yet, if you say "go home" on the last bus, the bus will never stop.
The filter gave Lin Yuan a temporary labor contract, a stick that would incur "debts", and a woman's voice that guided him in his ears.
Lin Yuan just wanted to figure out two things: why the bell rang, and where his father, whom he had never met, went.
But the door beneath Nancheng is cracking. The seal is valid for twenty-three years. This is the last year.
