Xiao Yao became a "beriberi doctor" two years after joining the company. After being harassed by the doctor and dumped, he awakened to the medical encyclopedia system. He unlocked all-round scientific and technological capabilities, solved difficult and miscellaneous diseases such as sepsis and paraquat poisoning, resolved conflicts between doctors and patients, and counterattacked to become the backbone of the emergency department. Faced with provocations from airborne interns and disruption by Internet celebrity doctors, he stuck to his original intention as a doctor, led key surgeries such as bone marrow transplantation, and was eventually promoted to resident doctor, promoting the spirit of Chinese medicine.
