Cheng Feng from the County Forestry Bureau was sent to Jiulong Mountain to investigate an illegal logging incident because he had just graduated and had no qualifications or background. The person who received him was Lao Lin from the forestry station. As an old man at the station, he was the direct person in charge of Jiulong Mountain. Faced with the trend imposed by the Forestry Bureau, Lao Lin was very uncooperative. He even expressed doubts about the authenticity of the illegal logging incident, saying that there was no such thing. Faced with this situation, Chengfeng was also very embarrassed, and there were rumors that Lao Lin was also the father of his love interest Xu Zhinan.
The strange Jiulong Mountain has returned to the eyes of the villagers once again with a series of bizarre incidents such as "ghosts breaking into walls", "tea pickers dying" and "five-step snake attacks". What happened to Jiulong Mountain, which is regarded as a "sacred mountain" by nearby people? For a while, the nearby villagers were unable to escape. Facing the mysterious Jiulong Mountain, they remained silent, and even the timid ones did not dare to step into it.
When Cheng Feng visited and investigated cases, Lao Lin always appeared at critical moments. Cheng Feng had to suspect that Lao Lin was the mole. He even felt that the incident of catching wind and shadow was fabricated by Lao Lin. He was the one who colluded internally and externally with the illegal logging gang and embezzled national property. At this time, Chengfeng reported to the Kowloon Township Timber Processing Factory, which affected the start of their factory. I had to return to the county seat. But Lao Lin single-handedly borne all the negative consequences. Until a passerby returning home at night was attacked and killed by hunters thinking he was a wild boar. But Orion miraculously disappeared after the incident, so Chengfeng returned to the forestry station again. Because the person who died at night was the father of his lover Xu Zhinan.
