The soul travels back to 1852, and a modern young man is reborn as 29-year-old Li Hongzhang, at a time when the Taiping Heavenly Kingdom was just beginning and the Qing court was in turmoil. He is familiar with the general trend of history for a century, but he is at the beginning of the decline of the empire. With a letter from Zeng Guofan, he embarked on the journey of the Hunan Army, strategizing, training troops, controlling power, and defending against enemies, from the Hanlin scrolls to the temple battlefield. Resurgence or collapse? He vowed to use his own efforts to extend the life of the Qing Dynasty for thirty years! Westernization, political intrigues, reforms, wars, and confrontations between great powers are all described in this pen, a diary, a history of an empire that defied fate and changed its destiny!
