In his previous life, Li Xiaoyao, the seventh prince of the Yan Dynasty, was defeated miserably in the court struggle because of his cowardly character and lack of knowledge of politics. He was framed to death by the prince. Destiny gave him a second chance - to be reborn at the age of 25, and he was determined to change his tragic fate.
Relying on his past life memories and prediction of the future, Li Xiaoyao originally wanted to be a carefree and idle prince, staying away from power disputes. But in the emperor's house, how can one be truly free? The prince Li Chengqian is ambitious, the third prince Li Chengze is deep in the city, and the queen mother Wang is very controlling. All forces are watching. On the border, Huyan Lie, the Xiongnu Chanyu, led his cavalry south, and the war was about to break out.
He was forced to get involved in the whirlpool of the court: rectifying the palace to establish a foundation, taking the initiative to invite soldiers to go to the border, and using modern tactics to outwit the enemy. In the tests of life and death, he met close friends such as Zhao Tieshan, the general of Zhenbei, and Lin Wan'er, the daughter of the Minister of Household Affairs, and gradually gained a foothold in the court. However, due to his high achievements, Emperor Li Yuan used and guarded against him, and there was an undercurrent of suspicion among the emperor and his ministers.
From the cowardly prince who was framed to death, to the powerful military commander on the frontier, to the regent who assisted the young emperor - Li Xiaoyao chose to retreat bravely at the peak of his power. True freedom is not about being alone, but about having the ability to protect the ones you love and change the direction of history. Let's see how this reborn prince walks his own path to becoming a king in the turbulent Yanchao Hall, and finally realizes his life ideal of "Happy Prince".
