A graduate student in a top-level hospital with a background of modern medicine, facing the darkest moment of career collapse and doctor-patient relationship collapse, was bound by a mysterious system that could "see through the causes, causes, and consequences of disease." Her job is no longer to prescribe medicine according to the procedure, but she must work like a detective, through the "medical record tree" provided by the system, to find the "culprit" at the bottom of the disease - it may be a childhood trauma, long-term emotional depression, family inheritance, environmental pollution or workplace PUA. She must use medical means to cut off the "cause" instead of dealing with the "effect". Every successful change of destiny will increase her own medical points, unlocking more powerful diagnostic capabilities and department resources, but it will also make the "karma book" in the background of the system continue to turn red, as if to warn her: every change you make will cause new ripples.
