The Blind Zone Prison

Shanghai, a stormy night, an old bookstore. Lu Chen finds a set of symbols from a damaged book—three concentric circles with a hole in the center, exactly matching the image he saw when he was dying. Following the symbols, he meets quantum physicist Lin Zhiyao and a young man in a psychiatric ward who can recite the first twenty digits of pi. The three discover that the city's drainage network, abandoned air-raid shelters, and doodles on medical records piece together the same map. At the end of the map lies October 4, 1957. On the night the Soviet satellite launched, an observation station recorded forty-seven seconds of electromagnetic anomaly, with only one line in the duty log: instrument calibration error. Some know the truth. Some pretend not to. And Lu Chen has just discovered that his memory has also been tampered with. When memory takes shape for the third time, the disc will no longer remain silent. The jailer has always been among them. — Description from novelcodex.org
