In the imaginary Daxia Dynasty, the imperial power fell to the side, the prince was involved in internal affairs, and there were powerful enemies around him. The national treasury is empty, the people are in dire straits, and we are on the eve of chaos.
The protagonist Li Xuan, a forgotten prince, accidentally activates the "Emperor Simulator System". The system can simulate various crises and provide options for Li Xuan to make decisions. Depending on the quality of the decision, the system will give rewards, including but not limited to: "Emperor Points" (can be exchanged for ancient wisdom crystals, black technology blueprints), "Attribute Points" (added charm, intelligence, force, etc.), "Treasures" - it can even allow time to be briefly reversed to correct fatal mistakes. The anti-routine thing about the system is that it never directly gives money or soldiers, but only provides information and knowledge, forcing the protagonist to use his brain to strategize, take advantage of the situation, and get rid of the wolf with nothing.
