Echoes from the Abyss: A Crime Scene Puzzle

Lin Yan, captain of the criminal investigation squad in Jiangcheng, W Country, and his team, including forensic examiner Su Wan and tech expert Lu Chen, solve one bizarre, seemingly flawless murder after another. It all begins with the case of an unidentified woman burned in a funeral home. Tiny clues, such as silvery-gray metal fragments and the symbol “Ω,” lead to Chen Mo, an AI expert who resigned from her job in F Country. She has bipolar disorder, created the “Abyss” AI, and leads a mercenary organization. Along with her close male friend and others, she orchestrates one perfect crime after another from behind the scenes, from a dismemberment case to a provocative bombing, supernatural murders, a perfect puppet stage, and the formation of an elite assassin squad tasked with shooting key figures around the world. As the investigation proceeds, Su Wan and Gu Cheng grow closer, though neither speaks openly of their feelings. Lin Yan leads his team in solving one strange case after another, tracing clues to the “Abyss” AI’s upgrades and following the trail through the fog, until they finally put an end to the crimes.
