Return of the Beast from Mountains and Seas

Jiang Yi is an ordinary magazine editor, and his life is ordinary. One day, his senior brother Xu She came to him and asked him to proofread, publish the posthumous works of his mentor Chen Jianmu who committed suicide, and write a preface. The posthumous work is titled "New Illustrations of Mountains and Seas", and the content is a secret interdisciplinary research project led by Chen Jianmu twenty years ago: "The bestiality tendency of human psychology in extreme environments." Chen Jianmu believes that the mythical beasts in "The Classic of Mountains and Seas" are not myths at all, but metaphorical records of specific personality disorders, psychopathy and extreme social phenomena by ancient ancestors. While sorting out the master's legacy, several shocking and strange cases also occurred in Kuncheng. Someone kept sending Jiang Xin paintings accompanying his posthumous works, which seemed to be a prelude to a murder. In the end, who is behind all this, the dead or the living? What secrets did Chen Jianmu hide in his posthumous works?
