The heroine Minghui wakes up and travels back to ancient times, an era that has not been recorded in history. During the Daqian Dynasty, she pretends to be a medicine boy and works in Kyoto medicine shops to collect medicines and make a living. While collecting herbs in the suburbs of Beijing, he met Liu Huaiqian, a down-and-out scholar from the south of the Yangtze River who came to Beijing to take the exam. He met Liu Huaiqian and supported him. The scholar was erudite and well-behaved, a bit pedantic, but in reality he was as smart as a fool. He got second place in the exam and was sent to the county magistrate. He was promoted step by step to the Minister of Household Affairs. It was only later that he realized the difference between male and female. The medicine boy turned out to be a daughter.
