Lin Yan, a key member of the Provincial Ecological Supervision Station, is urgently assigned to take over reclamation supervision at the Qingyangwa mining area. On this cursed land, the first three supervisors either quit or disappeared, leaving behind only a journal covered in strange symbols. Arriving on a stormy night, he enters an old house in an abandoned village and accidentally uncovers the secret of an underground cave system: the mountain guardians invented legends of a mountain god and sacrificed children to raise an ancient mutant monster.
Just as ecological restoration begins to show results and Qingyangwa is transformed into an eco-tourism area, tourists begin disappearing one after another. A snake-masked figure reappears in the valley, and the even more terrifying “Snake Mother” of legend emerges. The mysterious You organization is pulling the strings behind the scenes. Strange visions, mind control, and toxins from ancient creatures follow one after another. Armed with an ancient bronze sword and aided by the police and villagers, Lin Yan must fight bloodthirsty monsters and the remnants of a cult, while also digging into the You organization's financial secrets and the truth about the Snake Mother's origins.
From ghostly shadows in an abandoned village to terror in underground caves, from ecological restoration to a struggle for life and death, every inch of Qingyangwa hides dark secrets. Can Lin Yan uphold his duties as a supervisor, unravel the layers of conspiracy, and restore true peace to this land? A battle combining environmental governance, ancient mysteries, and horror suspense is about to unfold in the abandoned village.
