A senior student in the Department of Modern History unexpectedly passed through the book and became King Rong Jingxuan, who has the same name and surname as himself in the book. The original owner was a genius recognized by both the government and the public, but he was feared because of his too much talent, and eventually became a victim of court battles. Rong Jingxuan, who came through the book, has shed the impetuousness of modern times, inherited the talent of the original owner, and has a pattern and calmness that far exceeds the world. He has no golden finger to support him, and relies only on his own wisdom and strategy to navigate the turbulent court step by step. Above the court, various forces are fighting openly and covertly, and there are also villains who are like wallflowers who take advantage of the situation, add chaos and obstruction, trying to drag him into the abyss. Rong Jingxuan has always been calm and steady, not pursuing quick success or pursuing immediate gains. He resolves crises on all sides and wins people's hearts, while at the same time rectifying the political agenda and appeasing the people. From the game in the court to the layout of the world, as a prince, he single-handedly wiped out the traitors, balanced the forces of all parties, and finally ended the disputes in the troubled times, took charge of the world, and became a legend of a wise king.
