Lin Wanxing, a graduate student in the history department, was involved in the Dayin Dynasty by mysterious forces while studying ancient glazed pendants late at night, and his soul was transformed into the concubine Shu who fell into the water and fell into a coma. Facing the splendid palace and a strange identity, she relied on historical knowledge and modern thinking to navigate the crisis-ridden harem step by step. During the turmoil in the side palace, she unexpectedly received the protection of Emperor Xiao Yu, but she also fell into isolation due to rumors of a "witch". The diary of a former princess found in an abandoned study reveals the secret of Liu Li Pei's time travel, and also implicates the emperor's brother Xiao Jing's conspiracy to usurp the throne.
With the awakening of the ability to communicate with ancient artifacts, Lin Wanxing gradually uncovered the mystery of the "return to ruins" of the twin glazed pendants. When Xiao Jing's ambition and blood ties collide fiercely, she makes a choice between family affection and morality, and uses her wisdom to crush the conspiracy. Faced with the opportunity to return to modern times, she chose to stay and assist Xiao Yu in creating a prosperous age with modern agriculture and education concepts. From a graduate student in the history books to a virtuous queen in the world of mother-in-law, Lin Wanxing used knowledge to change the fate of the dynasty, and together with Xiao Yu wrote a legend of governing the country across time and space, and the glazed pendant that witnessed everything eventually became a silent witness to the glory of the prosperous age and eternal love.
