In the last years of Hongwu in the Ming Dynasty, Zhu Yuanzhang, the leader of Xiongcai, had a strange dream at night, and unexpectedly met a descendant named Zhu Shangxian six hundred years later through the air. One is an iron-blooded emperor who established a dynasty in blood and fire and worried about inheritance, and the other is an ordinary young man who is familiar with history and lives in the information age. When modern knowledge and ancient power collide, Zhu Yuanzhang's shock and suspicion, and Zhu Shangxian's fear and caution are intertwined into a picture that changes history. From the danger of the crown prince to the chaos of powerful ministers, Zhu Yuanzhang relied on the "prophecy" of his "divine grandson" to set off shocking waves in the court, and every "spoiler" Zhu Shangxian made pushed the future of himself and the Ming Dynasty into an unknown direction.
