After an overworked modern young man, Li Hao, is crushed by the 996 grind and dies unexpectedly, he is reborn as Goujian, King of Yue, who has been defeated, captured, and is about to become a slave to Fuchai, King of Wu. Armed with modern knowledge, management principles, a historical golden finger, and only a hazy memory of the story of “sleeping on brushwood and tasting gall,” he is forced to embark, amid fear and resentment, on a path of revenge and resurgence far more perilous than the history books recount, more demanding of human nature, and more radical in its consequences. How will he use modern thinking to survive and thrive in the wild Spring and Autumn era, and rebuild himself and his country after taking revenge?
