Strange Night in the Ancient City

In an ancient city in the north, there is a well-maintained ancient garden. It has accompanied the city for thousands of years, leaving behind many stories and legends that are either beautiful, touching, fantastic, or weird. Our protagonist, Lao Mu, moved to a police station next to it due to work transfer and became a film police officer. Here he experienced and heard many strange things. I want to present what he saw and heard one by one to friends who read the story. I just hope everyone likes it.
