Lin Xiaoyu, a graduate student at Modern Medical University, accidentally traveled to the fictional dynasty "Da Yin Dynasty" while rescuing ancient books on a rainy night, and his soul was possessed by Su Wanyue, the daughter of the Imperial Medical College's Classics Order. At this time, the Great Yin Dynasty was in the whirlpool of the "North-South Controversy" - Northern Xinjiang clans controlled the military power, Jiangnan aristocratic families monopolized the medical bureaucracy, and Su Wanyue's fate was tightly bound by a political marriage to Xiao Chengyu, the general who determined the north of Northern Xinjiang. This iron-blooded general who holds the "Xuanjia Army" is caught in the undercurrent of the prince's struggle, and the modern medical knowledge brought by Lin Xiaoyu will make waves in this era of "medical officers are not allowed to interfere in politics".
