"Silent Echo" is a suspenseful masterpiece focusing on technological ethics and social surveillance. Former algorithm engineer Chen Mo was framed and reclusive for exposing loopholes in the "City Eyes" system, but was forced to re-investigate the truth when unusual deaths occurred among his neighbors in Laojie. He teamed up with Internet police officer Li Yue and discovered that the technology giant "Zhiyuan Technology", through the "Urban Emotion Sensing System" and in the name of "Purification Protocol", used big data to mark "unstable individuals" and create "natural death" to eliminate social "redundancy". As the investigation deepens, they uncover the twisted truth of their mentor Professor Wang's "ultimate plan" three years ago - the so-called "social optimization" is actually a digital cage built using biological experiments and emotional manipulation. The story takes the life and death investigation of Chen Mo and Li Yue as the main line. In the dark background of technology and the glimmer of human nature, it asks: When algorithms begin to judge human nature, can we still hear the true echo?
