The Emergency Department of the First City Hospital is the hospital's "hospital". As the attending physician, Chen Feng was ridiculed as a "barbarian" because he insisted on performing bedside surgeries on critically ill patients. In a mass poisoning incident, a patient's airway was completely blocked, and all departments refused to admit him. With the cooperation of Tang Ruoxi, Chen Feng opened the patient's trachea with one knife and completed the bedside emergency cricothyroidotomy. Not only did he save the life, but he also tore away the fig leaf of the hospital's factional strife. However, this stab also made him involved in a deeper storm - Liu Wenbin took the opportunity to launch a medical accident investigation, Zheng Guoliang was forced to take sides, and the secret account mastered by Meng Yao became the only bargaining chip for a comeback.
