Synopsis：The case of the Ye family massacre had yet to be officially closed when Shen Qi's remains triggered a supernatural incident. Fortunately, Shen Qi's cousin—physicist Shen Yu, who had studied abroad for years—returned to China in time. Using her research on "dark matter" in quantum physics, she discovered that the witch Qu Nanyan had not actually died, but had instead possessed the elderly Madam Ye. After her scheme was exposed, Qu Nanyan killed Madam Ye and stole *The Book of Strange Arts from the Mountains and Seas* to reshape her body. Restored to power, Qu Nanyan became even more crazed, from manipulating corpse puppets to attack the group, to enslaving the townspeople of Ye Family Town as tools for her cultivation of the nine-tailed fox. With Shen Yu's help, Ali, Bao Tianyao, and Chun Han began to rescue the townsfolk. However, Qu Nanyan took control of Ali's childhood friend A Zhong, who was the closest to him, and had Chun Han, the inspector, killed. Ali had no choice but to use fox fire to burn A Zhong to death. Facing the deaths of family and close friends, Ali, Bao Tianyao, and Shen Yu were devastated. At this point, Ye Family Town was in unprecedented crisis. Shen Yu used the energy in Ali's blood to invent a dark matter energy gun. Ali and Bao Tianyao continued to prevent Qu Nanyan from turning the townspeople into corpse puppets. In the end, Ali infused the dark matter energy gun with the power of his demon core to defeat Qu Nanyan.
