The Deposed Prince? No, I'm a Modern Strategist

In the cold winter of the third year of Tianqi, the deposed prince Li Xuan has been imprisoned in the cold palace for three years. The prince who used to be well-dressed and well-fed is now in rags and is trampled upon by others. In the past three years, he has experienced the pain of falling from the clouds into the abyss, and witnessed the ugliness of human nature and the ruthlessness of power. However, on this desperate winter night, an unexpected high fever gave him memories from thousands of years later - the knowledge, thinking and wisdom of a modern strategist. When the second ray of sunlight shone on his face through the broken window of the cold palace, Li Xuan was no longer the abandoned prince who was at the mercy of others. His eyes shone with the light of modern wisdom, and his heart was filled with determination to change his destiny. He knew that in this court where the weak were the strongest, only power could protect him, and only strategy could achieve revenge. There are undercurrents in the political situation of the Dayong Dynasty: the dictatorship of foreign relatives, the power of civil servants, empty border defenses, and people's livelihood is difficult. This once glorious dynasty is in decline and needs a strong hand to turn things around. And Li Xuan, the deposed prince with modern wisdom, is destined to make waves in this game of power. The chess game of intrigue has been laid out, and the gears of destiny have begun to turn. How will Li Xuan use wisdom that transcends the times to survive step by step in this complex political environment? How will he face his cunning brother, suspicious father, and power-hungry queen? Who will be the ultimate winner in this power struggle across time and space?
