Xiao Wanzi (played by Zhang Ting) sneaked into the Hong Kong Convention and Exhibition Center and tried to steal a cultural relic called "Dream Fairy Pillow". He was caught by Hong Kong policewoman Zhang Chuchu (played by Liu Lili). During the fight between the two, it was an astronomical wonder that only happens once a century - thirteen planets lined up in a straight line at midnight. At that moment, the two disappeared out of thin air. When he woke up again, Xiao Wanzi had arrived at the palace of the Ming Dynasty hundreds of years ago. On the other side, Zhang Chuchu also traveled to the Ming Dynasty but fell into the folk. The two modern women who broke into the palace of the Ming Dynasty for no reason met two royal children, Zhu Yunwen (played by Xu Zheng) and Zhu Di (played by Wan Hongjie). The power struggle in the palace was undercurrent. Although Zhu Yunwen was Zhu Yuanzhang's favorite grandson, the ambitious Zhu Di had always coveted the throne. Xiao Wanzi and Chuchu are very familiar with this period of history. What kind of impact can they have on history? How will their love end?
