In the fourth year of Jianwen's reign, on the eve of Yingtian Mansion's destruction of the city, the failed emperor was about to burn himself to death. A soul from modern times traveled through time and was bound to the unique "Ming Dynasty National Games System" - upon signing in at the beginning, you will get five hundred elite tigers, a secret map of the Yan army's full-scale defense, and a list of internal countermeasures and instigators. He is no longer the indecisive Emperor Jianwen, but a chess player who changes his destiny on the edge of a knife: attacking the Chinese army at night, burning the arsenal, instigating internal counterattacks, and closing the game inch by inch in a desperate situation. When the wheel of history deviates from the established track, firearms blueprints, Western routes, and the Mobei Protectorate will appear one by one. In this life, he not only wants to protect Yingtian Mansion, but also wants to bring the fate of the Ming Dynasty to a completely different peak. The country is like a chess game, and the fate of the country is at stake. Let's see how an emperor can rebuild the country from a desperate situation.
