Su Wanyi, an urban white-collar worker, is haunted by strange dreams every night. In her dreams, there are always figures calling her to "come back quickly." I was restless all day, and was suggested by my colleagues to go to the temple to relax, but was inexplicably enlightened by a master Huiyuan, who left a motto: "A dream is the same in ancient and modern times, and this body is the way home." Not long after, an accident caused her to suddenly travel through time and become Su Yunwan, a 13-year-old peasant girl who had just experienced death in the ancient Su family and was supposed to be stupid.
When she woke up, she found herself in a big, poor but extremely warm family. Her family was ecstatic because of her "sobriety", because an eminent monk once predicted that when her soul returns to its rightful place, a lucky star will come to this world, the four kingdoms will be reunited, and the world will be at peace! At the same time, the abbot of Huguo Temple sensed a change in destiny, and Prince Huangfu Heng was ordered to secretly go to the capital to search.
With modern knowledge, Su Yunwan led the united Su family to grow high-yield grains and open a restaurant, making life more prosperous. The prince who goes by the pseudonym "Han Heng" quietly approaches as a collaborator. They are attracted to each other but each has their own secrets. When Su Yunwan's influence touched the interests of all parties and attracted murderous intent, the prince revealed his identity and begged her to join hands and return to the capital.
For the safety of his family, for the world to no longer suffer from the flames of war, and for the affection that silently guards him, Su Yunwan resolutely stepped into the court. From then on, Princess Fuxing and the prince worked side by side to cut off conspiracies and quell turmoil. With wisdom and benevolence, they gradually promoted the prophecy of "the unification of the four kingdoms" to become a reality. Finally, they created a prosperous age and gained the only deep love between an emperor and an empress in her life and a happy family.
