The Eternal Night Code: Rule Thirteen

The monthly salary is 50,000 yuan, and I only work night shifts. There is no experience requirement, the only condition is: hard life. Lin Wan urgently needed the money. Her brother is lying in the hospital, and the daily hospitalization fee is 3,460 yuan. So she walked into the alley that couldn't be found on the map and opened the door with a backward clock. On her first night on the job, she got a handwritten copy of the "Employee Code of Conduct" with twelve articles. That night, she found a second copy in the front desk drawer. Two contents, completely opposite. One said: At three o'clock in the morning, no matter who knocks on the door, don't open it. Another said: If someone knocks on the door at three o'clock in the morning, you must open it. The two comments at the end are also lying. Lin Wan took out the medical record and began to verify it one by one. She used the method of observing patients to observe every wall, every mirror in this hotel, and every person who walked out of the elevator after eleven o'clock at night. Later she discovered that all the people who left the hotel had no traces. And her shadow has been different from others since the day she was born. Because her name is the thirteenth rule of the hotel.
