The world is in chaos, the way of heaven appears, and the entire world turns into a real sandbox game called "Tian Xia Yi" without any warning. All the people are soldiers, and the heroes are chess players. Everyone has a gamified attribute panel and follows the cold rules to survive.
Gu Changce, a poor Confucian scholar, was ridiculed by the world as a nerd who did not do his job because he was obsessed with studying the long-lost ancient book "The Game Book of the World". However, when the world became gamified, the knowledge he mastered that was considered "useless" - the hidden loopholes in the game rules, the distribution of resource points, the recruitment conditions of special units, and the triggering mechanism of historical events - became his only and strongest weapon.
Without a system or a golden finger, Gu Changce relied on his extraordinary understanding of the "game" to succeed step by step. He perfectly combined human nature, military skills, strategy and game rules, and turned a deserted county that was about to be starved into the most powerful city in the world. Recruit famous generals, recruit beauties, fight princes, and resist natural disasters. When all the "players" were still groping for the rules, he had already begun to use the rules to lay out the world; when the princes were complacent about a victory, he was already a hundred steps away on the chessboard. This is the story of a strategist who, in a real game world, uses heaven and earth as a chessboard and all living beings as chess pieces, and ultimately strives to conquer the world.
