Once he traveled through time, Jamel Xiao became the prince of a subjugated country—the "wasted prince" who was poisoned by his own father, burned the imperial city, and was despised by the world. But when he opened his eyes, he found that he was holding a "fate-defying chessboard" in which every move could rewrite the trajectory of history: kill a traitor, and the country's fortunes will rise slightly; save a refugee, and the people's popularity will skyrocket; marry an enemy princess, and the enemy's army will be in chaos. He no longer begged for the restoration of the country, but overturned the decadent chess game of imperial power. The court is a chessboard, the world is a chess piece, and he wants to be the one who plays chess. When the cavalry broke through the palace gate and the people shouted "New Emperor", he sneered: "What you want is not a prince, but a tyrant who can change the world."
