Jiangnan scholar Shao Yu (actually the second prince of Dayong, Zhu Che) suffered from the strange disease "Fragmentation" since childhood, but in fact he possesses the Su family's talent "Dream Walking Technique" - the ability to sneak into other people's dreams, read consciousness and even control the spirit. Before he went to Beijing to take the exam, he accidentally got involved in the power struggle between the crown prince Zhu Cihong and his chief minister Zhou Yanru. Zhou Yanru treated him as a pawn and joined the palace. He was also recognized as a brother by the crown prince because of the mystery of his life experience. In fact, both sides wanted to take advantage of his special abilities. As the truth about the witchcraft case, the late emperor's edict, and the massacre of the Su family were revealed one by one, Zhu Che knew that he was the crown prince designated by the late emperor, and he was responsible for the blood feud between his mother, Concubine Su, and more than 300 members of the Su family. He dealt with Zhou Yanru's conspiracy, the prince's ambition, and the invasion of Beidi. He united with the old Su family, Jiangnan Navy and loyal minister Li Chong. Using the art of dream travel as a blade and the righteousness of his family and country as a shield, he struggled to move forward in the whirlpool of imperial power and the flames of war. He not only wanted to wash away his grievances and protect the Great Yong Mountains, but also break away from the fate of the chess pieces and control his own future and that of the world.
