In the emergency surgery department of Jiangcheng No. 1 Hospital, Lin Ziyang, the "Iron-Blooded King of Hell", and Shen Anran, the Gentle Blade, met due to a heart rupture emergency. One is a rational surgeon who adheres to "data first", and the other is a humanistic doctor who firmly believes in "temperature treatment". In the emergency room, at the speed of life and death, the two went from "opposition of treatment concepts" to "soul resonance", and jointly uncovered the human nature test questions behind the medical system - and the "white coat" hidden in their childhood memories has already laid the foundation for the intertwined fate.
