Fog Locked Old Building

The old family building "Huaianli Building 3" is always filled with fog that cannot be cleared away at dusk. Lin Wan, who lives alone, always feels strange noises in her home, and late at night she sees a strange woman in red repeatedly knocking on the opposite door - a room that is said to have been vacant for a long time. As she traces the identity of the woman and the old events in the building, the strange behavior of the neighbors, the flashing black shadows in the corridor surveillance, and the fragments of her own gradually blurred memory are intertwined. When she finally pried open the door to the secret, she discovered that the fog not only hid the truth about the missing people, but also entangled her and the fate of the building that had been tampered with. Every time the door rang, it was an "invitation" sent to her by the darkness. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
