Lu Chen, an intern in the emergency department of Jiangcheng Central Hospital, appears to have relatively low qualifications, but in fact he possesses extraordinary calmness and talent. After joining the hospital, he shocked the whole hospital with his "textbook-level" laparoscopic surgery in 23 minutes with zero bleeding, and even saved the brain hernia crisis in a serious car accident. Selected to participate in Kyoto's top medical training, he broke records with perfect skills, led the team to win the championship with outstanding leadership, and bravely passed the most difficult test and won first place. After returning with great honors, he knows that the real battlefield is not on the podium, but at every rescue scene where life and death are on the line.
