Wugang No. 2 Middle School is hidden in a mountain valley on the outskirts of the city. It was formerly a military academy of the Republic of China. Centennial cypress trees block out the sky. The Martyrs' Mausoleum and Zhongshan Hall stand gloomily. The adjacent forest park gives the entire campus a deep and cold feeling all year round. Xiao Chen is the wife of a mountain god in a Miao village in western Hunan. She was born to drink from the mountain spring, have yin and yang eyes, and can distinguish evil spirits. In the city, she is just an ordinary girl who is taciturn and speaks with a local accent.
Zhang Haoyao, a popular young man on campus, fell in love with this alienated Xiangxi girl. He was so proud that he didn't know how to express it, so he only dared to approach repeatedly in a clumsy and hurtful way. His paranoid obsession quietly fermented in the cold campus. A confession and rejection in a bamboo forest became the beginning of tragedy - the mountain evil that lurked in the shadows of the campus followed Zhang Haoyao's extreme obsession and took advantage of it, sucking out his soul and causing him to die in a strange and tragic way.
Xiao Chen was the only one who had a glimpse of the truth, but because of the identity of the Mountain Goddess, all clues pointed to her. Rumors spread around the campus, and she became the "disaster" that everyone avoided. Interpol Lu Zhe intervenes in the investigation. From the strange death and the poisonous clues from western Hunan, he gradually comes into contact with the mysterious inheritance of the Miao village in western Hunan, and suspects that this silent girl is not an ordinary student.
In the deep campus, the hostility of the military academy, the depression of the Martyrs' Mausoleum, the obsession of the people, and the evil spirits in the mountains are intertwined into a web. Xiao Chen wants to hide his identity to avoid tracing, while trying his best to kill the evil spirits. Lu Zhe's step by step pursuit is not only uncovering the truth about the murder case, but also touching the fate and loneliness of the mountain god's wife that has not changed for centuries.
When the Yin evil's claws extend to more innocent people, when the destiny he has believed in since childhood collides with the justice of the world, how should Xiao Chen make a choice.
