Lin Wei, a modern medical student, accidentally traveled to the Wu Dynasty. When she opened her eyes, she became the daughter of Lin Wenyan, the framed imperial censor. She embarked on the road to exile as the "daughter of a guilty minister". In order to clear her father's grievances, she relied on modern medical knowledge and a calm mind to resolve crises many times during her exile - from treating soldiers attacked by wild boars to using herbal medicine to solve the team's food shortage. She even accidentally formed a bond with the powerful regent Xiao Jue.
With in-depth investigation, Lin Wei discovered that behind her father's injustice, there was a huge conspiracy of King Zhao. Copies of the case files, mysterious secrets, hidden witnesses...

The ultimate battle involving life and death and the redress of unjust cases was quietly beginning...
