Lin Xuan, a young doctor from a secluded mountain sect, descends into the world at his master's command to settle a long-buried debt of fate.
When he first arrives in the city, he's just an unremarkable intern at a municipal hospital, but he possesses the lost "Classic of Xuanmen Medicine". One needle can decide life or death; one glance can reveal the source of an illness. And with his awakened medical-path golden finger, every patient he heals grants him a corresponding insight into medicine, a fragment of a cultivation technique, or the power of a secret art.
From strange and stubborn ailments to terminal illnesses and patients hovering at death's door, even those given a death sentence by the authorities are brought back to life in his hands.
He treats more than illness: he treats fate, fortune, and karma.
As his fame grows, wealthy families seek his care, ancient clans bow their heads, and powerful figures invite him to their side. Forces from every quarter come rushing in.
Beneath the surface, medical showdowns grow increasingly fierce, while old cases gradually come to light. The great medical families, underground forces, corporate titans, and ancient martial sects all make their entrances.
Only when the facade of city life is stripped away does Lin Xuan realize that his descent from the mountain was no coincidence.
A massacre deliberately buried, and a hidden thread linking medicine and martial arts, are steadily drawing him toward the heart of the storm.
A silver needle falls, and life or death is decided.
In the city, he enters the Dao through medicine and uses the Dao to command the world.
