Lin Yuan, an international strategic analyst, died suddenly and traveled through time to become the weakest puppet prince in the Canglan Continent. When you open your eyes, poisonous wine penetrates your intestines, power threatens the palace, and murderous intent is everywhere. Without the blessing of the system or the magic secrets, he only relied on a mind that has insight into human nature and modern game theory to defeat the game in a desperate situation. In the court, he pretends to be a pig and eats the tiger, and eradicates the traitor with "two peaches and three soldiers"; outside the battlefield, he joins forces and concludes fragile alliances with his tongue; deep in the palace, he quietly promotes changes in gunpowder and system. From being a trapped beast in a lonely city to being the leader of the world, what he used to crush his opponents was not his personal force, but his strategic thinking and organizational power that transcended the times. When the mysterious organization "Star Palace" attacks his empire with destiny as its blade, Lin Yuan plays chess and declares to the whole world: "The rules on this chessboard are written by the person who made them. And now, the chess player - is me." This is the ultimate battle of wits of a counselor who uses the world as the chessboard, a dimensionality reduction attack of modern thinking on the classical world, and a passionate legend of working step by step in a desperate situation, and finally becoming an emperor for the ages.
