在叶家大案尚未正式结束时，又出现了神秘异事，沈琦遗骸的扰泥再度引发恐怖之波。 Fortunately, Shen Yü returns to China, utilizing her expertise in quantum physics, specifically regarding 'dark matter', she uncovers the truth that the so-called witch, Curr South Yan, is still alive and possessing Lei's grandmother.
However, Curr South Yan's schemes are soon exposed, leading to the murder of Lei's grandmother and theft of 'The Mountain Guide's Mystical Records'. Upon resurfacing, Curr South Yan becomes even more maniacal, manipulating corpses to attack the townsfolk and controlling them as tools for her nine-tailed fox cultivation.
Ao Li, Bai Tian Yao, and Chun Huan join forces with Shen Yü to save the townsfolk. Little did they know that Curr South Yan had control over Ao Li's closest childhood friend, A Zhong, leading to his tragic demise. Spring Huan's team leader is also killed by her hands, leaving Ao Li with no choice but to use Fox Fire to burn A Zhong alive. Facing the loss of loved ones and friends, Ao Li, Bai Tian Yao, and Shen Yü suffer immense sorrow.
At this critical moment, Lei's town is in grave danger. Using the energy stored in Ao Li's blood, Shen Yü invents a 'Dark Matter Energy Gun'. Despite the odds, Ao Li and Bai Tian Yao continue to stop Curr South Yan from turning the townsfolk into corpses. In the end, Ao Li uses a potion of fox power to infuse the Dark Matter Energy Gun, defeating Curr South Yan.
