After her parents disappeared, Xiang Ya was in huge debt. When she had a headache to repay the money, a recruitment notice was slipped under the door of her house. A mysterious website recruits hotel sleep testers with extremely high salaries, and they only need to submit their accommodation experiences in designated hotels and propose solutions. Excited to submit his resume to Ya, he received an invitation from a hotel that night. The first hotel was so popular that there would be elevators full of people going up and down in the middle of the night, there would always be women pushing strollers outside the corridors, and children with fangs would stare at people begging for sweets... Xiang Ya tried her best to ignore these unscientific anomalies until she dreamed of a murder case during a sleep test. Three days later, she found that the dream had come true. Only then did she believe that the job she was applying for was somewhat creepy and scary. ... Detective Zhang Fanyu noticed a strange girl who always appeared in hotels where homicides happened or were about to happen. He managed to catch the suspect in a ravine. As a result, the suspect climbed up from the cemetery carrying a pair of bones and ashes. There was an aura of "I'm suspicious" all over her body... After helping another ghost tenant solve the case, Xiang Ya wanted to give it a respectable ride. Just as the other's bones were pulled out, an unbelievably handsome policeman was standing solemnly in front of the grave. Xiang Ya stared at the muzzle of the gun aimed at her, and pointed to the bones on her back: Uncle policeman, I said I'm going to help her put on a new dress, do you believe it? Zhang Fanyu sneered: Now the suspects have learned to talk about digging graves so freshly and refinedly.
