Ye Qingtang, a graduate student in the Department of History, once traveled through time and became a poor peasant girl who was plagued by famine in the late Southern Song Dynasty. The family is surrounded by poverty, her mother is seriously ill, and her younger siblings are crying for food. She is trying to survive in troubled times, but she has no power to tie the chicken? No! Modern thinking is her strongest golden finger! Starting from a simple piece of soap, she improved farm tools, promoted hygiene knowledge, used knowledge to fight plagues, and used wisdom to resolve crises. The cold-faced general Xiao Ce, who once dismissed her "wonderful skills", was gradually attracted by her intelligence and resilience. Aunt Wang, a mean and snobbish village woman, became her "guide" to integrate into the ancient times. From farmyards to temples, from rampant plagues to resisting foreign enemies, Ye Qingtang used her female body to stir up the storms of the Southern Song Dynasty. With modern wisdom, she revitalized a dynasty, eventually reversing the trend of history and creating a prosperous age!
