The Sound of Deserted Factory

The twin brothers Zheng Qi and Zheng Xueqing, who went back to the mountains to visit their grandmother, entered the arsenal that had been abandoned for many years with the purpose of exploring. The black leather diary, the rusty iron box, and an old key that could not be matched completely broke their peaceful life. A taboo that cannot be touched all year round in a mountain village, a small mountain village where strange things happen frequently. The mysterious man with mysterious whereabouts lingers in the abandoned factory all year round. It is difficult to tell whether the ghost rumors that have been passed down in the village from generation to generation are true or false. Others only knew that the abandoned factory was empty and strange, but Zheng Qi often heard intermittent whispers. The past that my grandmother deliberately concealed, the tragedy that shocked the county many years ago, and the taboo place that the villagers kept secret. As the secret contents in the black leather diary are revealed bit by bit, the old grudges buried deep under the dust of the abandoned factory are slowly approaching the brother and sister. Is the ghostly sound in the middle of the night a lingering ghost, or is it a mystery carefully laid by a living person?
