Jin Xing grew up in a scientific research station on the interstellar frontier since he was a child, and his ambition is to analyze the signals of alien civilizations in the dust of the universe. Due to an accidental data anomaly, she captured an extremely weak, unclassifiable frequency that seemed to come from an unknown existence deep in the universe. Jinxing shuttled between science and faith, reality and illusion, gradually uncovering the extremely delicate "language" behind the signals, only to find that what she was pursuing was not only the wisdom of the distant world, but also the projection of her own emotions. The doubts of the outside world and the loneliness inside entangled her. The signals gradually affected the consciousness of people in the station, and the boundaries of reality became blurred. Jinxing insists on letting the truth emerge, no matter the cost - she longs to understand the life on the other side, and she also longs to be understood. With meticulous psychological portrayal, the novel explores the boundaries between technology and emotion, loneliness and connection, and shows the poetic connection between unknown civilizations and human hearts in the depths of the universe.
