The reborn prince Shen Yian, in order to avenge the princess and his brother who poisoned him, proposed to marry Ye Liyan, the "devil" who was feared by the world, in public. This move not only unexpectedly revealed her illustrious identity as the granddaughter of the general who ruled the country, but also helped him win the Sacred Heart and enter the East Palace. Relying on his prediction of the future, he managed every step of the court games such as disaster relief and imperial examinations, and repeatedly thwarted the plots of political opponents. The two help each other in dangerous situations, and gradually become true lovers from allies who use each other. In the end, with the strong support of the Ye family army, he smashed the bloody palace coup launched by his opponents, eliminated all enemies, and successfully ascended the throne as emperor.
