Qin Ming, an 18-year-old top student in the history department in modern times, traveled to the twelfth year of Emperor Xiaozong's reign in the Ming Dynasty due to an accident in the laboratory. After Qin Ming was reborn, he quickly adapted to ancient life with his historical understanding and solid knowledge far beyond the times, repaired his original interpersonal relationships, passed the county and prefecture examinations with amazing talent, and was shortlisted for the Shuntian Prefecture Township Examination. The Qin and Ming dynasties traveled through the course of more than fifty years, from the 18-year-old champion to the first assistant of the five dynasties, assisting the five emperors Xiaozong, Wuzong, Shizong, Mu Zong, and Shenzong. Although they experienced power intrigues and several life and death crises, they always adhered to the original intention of "the heart of a lonely minister, only for the Ming Dynasty", carried out reforms, stabilized border defenses, and rectified the officialdom, and continued the national destiny of the Ming Dynasty for nearly a hundred years. In the end, Qin Ming died of illness in the presence of Emperor Wanli and his ministers at the age of 82 (actual age after time travel). Emperor Wanli posthumously awarded him the title of "Grand Master" and the posthumous title of "Wenzhong", and the whole country mourned.
