Yun Qingnang, the daughter of a declining medical family, was punished because her family was involved in a "military drug corruption case." She faked her death and escaped, sneaking into Chang'an under the pseudonym "Yan Hui", and founded the "Xuanhutang", a civilian medical clinic, to collect intelligence and vowed to avenge her grievances. On the way, they formed an alliance with Xiao Che, the Zhenbei general who was tasked with an undercover mission. The two used the medical clinic as a chess game and the art of benevolence as a blade to deal with the eunuch group, the power of the feudal kings and the alien races in the world. Finally, they uncovered the "chess player" who controlled the world behind the scenes, and opened up an innovative path of medicine to save the country in troubled times.
Purpose: Doctors can dominate the world, and benevolent can break the power situation
