Rusty Stethoscope

New work is released! In order to find his sister Lin Wan, who had been missing for 93 days, Lin Shen sneaked into the abandoned city hospital late at night. The half-sheet of "3:17" note and the strange stethoscope symbol left behind by his sister before she disappeared became his only clues. The hospital was filled with the putrid smell of formalin and rust, waist-high weeds were wrapped around rusty infusion tubes, glass fragments shone coldly in the water, and "3F" signs were hung on the stairs of each floor, as if they were trapped in an endless maze. On the second floor, he found an infusion bottle signed by his sister, with writing on the bottle that looked like a tearful face; in the register at the nurse's station on the third floor, next to the record of the stethoscope that his sister received the day before she disappeared, the number "317" was smudged in blood-red ink. What's even more creepy is that there is a dark red stethoscope that should have been sealed by the police on the glass counter. The stain on the rubber tube exactly matches the mark on my sister's work ID. When Lin Shen touched the stethoscope, the sound of slippers came from the corridor, and a figure in a nurse's uniform appeared - she had the same scar as her sister, but had a mole at the corner of her left eye (my sister's mole was at the corner of her right eye). The hoarse word "Brother" made him freeze instantly. While on the run, he found the jacket his father had left behind when he disappeared five years ago. The title page of his notebook in the inner pocket said: "3:17 Time will repeat, but there is only one truth." Finally, Lin Shen in the truck opened his notebook and found his sister's surgery records (time 2023.10.17 3:17). At this time, his cell phone received an unknown text message: In the photo, the notebook in his hand was placed on the glass counter of the nurse's station on the third floor. The mystery of the time of 3:17 and the secret of the rust-colored stethoscope
