Hong Kong Crossover: The Paranormal Police Bureau, Where I Slay Jiangshi and Gain Experience

Lin Cheng transmigrates into the 1980s as a police officer and unexpectedly discovers that ghosts and monsters are everywhere: a statue of Guan Yu wards off evil at the station, the dormitory is haunted, and a zombie lurks in the street. After unlocking a system that grants experience for killing monsters, he starts by practicing his knife skills on chickens, then slays zombies to boost his strength. When the old ghost Uncle Biao starts hounding him, he teams up with A Xing to break into a zombie den and fight the power struggles at the police station. With his strength, he carves out a place for himself in a supernatural world.
