Late at night in the old building of Jiangcheng University, the emergency lights flickered on and off. Lin Leyao encountered a shocking scene - in front of the blackboard, chalk was hanging in the air and "swishing" writing in blood. Dark red liquid dripped along the cracks of the blackboard, and finally formed the crooked word "rescue". Just as she was about to get closer, a man with a cold sandalwood gripped her wrist: "Don't touch the spirits here." The man was Gu Fan from Xuanqing Office. The woman beside her, Mo Ziqi, was spinning a golden copper coin. When she glanced at the tear mole in the corner of her eye, she suddenly changed: "The horoscope is yin, and the aura is strong. This is a pen fairy." Since then, Lin Leyao has been involved in a series of strange things: the dish fairy in the dormitory left bloody scratches, the red handstring wrapped around the nurse's wrist in the hospital morgue, and the eyes of the ancient mantong in the Southeast Asian rainforest turned red. Everyone in Xuanqing solved the obsession of the spirit body, but they didn't know that there was a dark shadow in the dark playing tricks on them with resentment. When Lin Leyao's yin and yang eyes suddenly became hot, the talisman in Gu Fan's arms suddenly appeared - is the obsession of these spirits a salvation, or a bait leading to a deeper abyss?
