In the glorious era when human civilization spread across the Milky Way, the vast star field at the outer edge of the Orion cantilever fell into deathly silence overnight. Thousands of prosperous colonial planets, countless starships passing by, all signals, lights and signs of life were erased as if by an invisible eraser, leaving only a heart-stopping darkness. This area was named the "Silent Tide Zone."
Ling Su, the Star Alliance's top star mapper and cosmic phenomenon analyst, is famous for his extraordinary rationality and almost paranoid pursuit of data. He was entrusted with the important task of deciphering this cosmic disaster. The only clue comes from Wen Xing, the only survivor found on the edge of the "Silent Tide Zone". She was an acoustic physicist on a research vessel. When she was discovered, her ship was silent and her memory fragmented into fragments full of contradictions and fears.
In order to uncover the truth, Ling Su must enter Wen Xing's chaotic spiritual world and piece together the last moments before the disaster. One of them believes in cold data, and the other relies on emotional responses. In this journey across the sea of stars and memories, they will jointly face an ancient secret that far exceeds human understanding. Under that silent star field, is it the end or another form of rebirth?
