As the only brothers with different surnames in the Daye Kingdom, Wang Suxuan and Ye Di, as opposite-sex brothers, support each other and trust each other to support the precarious Daye Kingdom. However, after the death of Emperor Ye, Empress Xiao changed the imperial edict and promoted her brother Xiao Jing to the position of assistant minister and controlled the government like a curtain behind the curtain. Su Xuan argued in the court that he would use his position as prince in exchange for Empress Xiao's cancellation of listening to politics behind the curtain.
Su Lingfeng, as the only good-for-nothing and playboy in the Su family, lived a carefree and speechless life under the care of Su Xuan and his two brothers. However, he was beaten to death in a conflict with Xiao Yun, the second son of the Xiao family. At the same time, the soul of the eldest son of the Su family in the modern age with the same name traveled to him and still lived such a bohemian life.
Under the design of Xiao Jing and Queen Xiao, Su Lingfeng's eldest brother Su Lingxiao was captured and committed suicide due to lack of food during the northern border resistance against Beidi. The second brother Su Lingyue also lost his official position because of being squeezed out. Since then, the Su family has plummeted.
Although Su Lingfeng was a person who traveled through time, he couldn't bear to see the Su family loyalists end up like this. Therefore, he joined forces with the fourth prince and the seventh princess who were suppressed by Queen Xiao to successfully help the fourth prince ascend to the ninth position, turn the tide for the Daye Kingdom, clarify the world, and reestablish the status of the Su family king of the Daye Kingdom with a different surname.
