In the "Mirror City" constructed of holographic glass and cold neon, memory has become a commodity that can be read and traded. Lin Mo, the top "memory diver", makes a living by sneaking into other people's memories and uncovering the deepest secrets. He is calm and distant, viewing emotions as noise in a stream of data. However, when he was hired to investigate the bizarre "suicide" case of technology giant Chen Jing, he sneaked into a last memory that was deliberately torn apart. The strange figure reflected on the window, the strange whisper echoing in his ears, and a silver pendant that did not belong to the deceased dragged Lin Mo into a carefully planned whirlpool of conspiracy. He must travel between true and false memory fragments, not only facing the huge forces hidden in the shadows of the city, but also facing a past that he has sealed long ago, which is enough to completely destroy him.
