In the emergency room, Lu Jin never spoke, but always performed precise cuts on the edge of life and death. He was called the "silent living compass." Until the new intern Shiye dared to look him directly in the eyes on the operating table and said: "What you are afraid of is not the technology, but the inability to save people." One night of heavy rain, the girl with myocardial infarction was carried into the emergency room. Lu Jin's hands were shaking, but Shiye tore through his layers of indifference, snatched the electric shock device and shouted: "I'm here, you watch." The collision of silence and roar at the rescue scene, which was broadcast live on the entire network, exploded the understanding of the medical community. No one knows that Lu Jin's silence is to bury the truth of a series of deaths; and Shiye's sharp edge is piercing the past that he dare not touch.
