Searching for People in Wuling

Wuling Sanatorium is surrounded by mountains on three sides, and the white mist never disperses all year round. Three months ago, the nurse Su Wan disappeared out of thin air in the blind spot of the back mountain surveillance. No one was seen alive and no body was found dead. Police conclusion: Lost on his own. But the grandfather firmly believed that his granddaughter was hidden in the fog. The down-and-out investigator Lin Shengsheng was entrusted into the mountains. As soon as he stepped into the sanatorium, strange things happened one after another. There were footsteps in the deserted corridor, scratching sounds on the wall in the abandoned ward, and the missing person's notebook appeared at his door late at night. A diary that reveals the truth about fear: They are in the fog and they are watching us. A ward that has been dusty for thirty years, a female patient who fell off a cliff more than ten years ago, The taboo hidden deep in the sanatorium is never a ghost, but a door to the unknown. Su Wan is not dead. Lin Wanzhou did not disappear. They are all trapped in the fog, waiting for someone to close the door. As soon as Lin Shen stepped into Wuling, he became the third one selected... This time, those who walk into the fog may not be able to come out.
