After traveling through time and becoming a deposed prince, Chu Yu bound the national destiny system and discovered that the loyalty of the civil and military officials of the Manchu Dynasty and the national destiny value of every decision were clearly visible. There are only 327/10000 left in Da Qi's national destiny, and the countdown is 91 days. If it reaches zero, the country will be destroyed and the body will die. Faced with Prime Minister Li Chong's interference and the enemy's gaze, Chu Yu pretended to be drunk and an idiot, secretly using the system to detect evidence of treason, subdue the northern general, and capture the enemy's prince alive. When everyone thought he was a puppet at the mercy of others, he had already laid a dragnet. However, there is far more than one real enemy - after unlocking the "World Chess Game" with a national luck value of 1,000, he discovered that seven continental kingdoms coexisted, and the most powerful Tianyu Kingdom was plotting to carve up Daqi. From deposing the prince to supervising the country, from turning the tide to pointing the sword at the world, Chu Yu's journey has just begun.
