Folklore investigator Chen Mo specializes in solving murder cases involving "ghosts". He doesn't believe in ghosts and gods, but he only believes in one thing: Anyone who scares people with legends must have someone behind them.
Volume One, Bayou Town. A red wedding dress floated on the river, and the bridge railings were covered with red cloth strips, each with a woman's name embroidered on it. Young female teacher Lin Xiaoyue was pushed into the river. Chen Mo jumped into the river to save her, only to find that the whole town was talking about "the marriage of the river god". He followed the red cloth strips and uncovered a human trafficking and real estate conspiracy in the name of "River God Festival". Fang Ying, Fang Ming, and Grandma Liu, everyone has secrets. Grandma Liu died in Chen Mo's arms and said her last words: "I didn't jump, someone pushed me."
The second volume, the paper-tied bride. The funeral parlor puts out a living stand-in, the paper mannequin at the funeral disappears in the middle of the night, and a real corpse appears in the funeral hall. Chen Mo investigated the case and discovered that behind the "paper tie for life" was inheritance competition and revenge.
Volume Three: Mandrill's Night Journey. There are rumors in the closed mountain village that mandrills cannibalize people, and strangers are missing one after another. Chen Mo went into the mountain and found that the villagers used the legend of the mandrill to cover up the lynching, and that a bigger secret was hidden in the cellar.
Volume Four, Gu Shadow. The poisonous poison found in the medicine market shocked people and killed people. Legend has it that the poisoner bled to death from his seven orifices. Chen Mo investigated and found that the so-called poison was just precise poisoning, and the formula was hidden in the medicine book of a local family.
Volume 5, the true form of the River God. Five volumes of clues gathered together, and the names of 13 red banners, 14 people in the "River God Festival" WeChat group, and a cross-regional human trafficking network gradually emerged. Chen Mo finally faced the "River God" who had never shown up - he was always there, closer than anyone thought.
