He can't remember anyone's face, but he has to remember all the truth within 60 days.
Lu Li, 35 years old, is a former neurosurgeon who became a forensic neurology consultant due to spatial cognitive overload syndrome. He couldn't see the face, only the gestures - the angle of the thumb's palm, the flexion tension of the index finger, the tapping frequency of the middle finger. Everyone's hands are a different anatomy, and anatomy doesn't lie. Algorithms do.
Zhou Muyun, director of the Neurosurgery Department of the Municipal Hospital, died from a "brainstem restricted area" surgery. The autopsy found that the brainstem incision had traces of bidirectional cuts. However, the surgical records showed that he died from the first hemorrhage and there was no time for the second operation. The only explanation: Someone had tampered with the coordinate origin of the DICOM navigation image before the operation, and it was offset by 1.2 Millimeters - in the brainstem area, that is the entire distance between life and death. The murderer did not touch any surgical instruments, only the data. Apart from the deceased, the only person with the highest authority was algorithm engineer Lin Shen.
Five years ago, Lin Shen was kicked out of the team because his mentor Zhou Muyun concealed a bug in the navigation system, and his father became a vegetable. Five years later, he started a precise revenge with a ruler of 1.2 Mm. When Lu Li formed an "unstable contract" with medical investigative reporter Su Xiao, he discovered that the murderer was upgrading the accuracy: from 1.2 Millimeters to 0.1 Millimeters, from the operating room to the live broadcast room, from coordinate offset to algorithm delay. The "successful operation" witnessed by 100,000 viewers was a lie of a corpse for 0.1 Seconds.
In the black box of medical AI, data has no fingerprints and algorithms have no faces. But Lu Li remembered the gestures - including the frequency of 1.2 Times per second when the murderer tapped on the table, and the 0.1 Second pause at the 57th second of every minute. Two people who have shifted the coordinate origin calibrate each other's gaits in the dark. The truth is never in logic, but in the light of 1.2 Mm.
Intention: When algorithms become murder weapons, conscience is the only coordinate origin.
