During China’s Warring Nations, Li Xin and Piao are two brothers, who, despite their poor status as orphaning slaves, dream of being Grands Generals. One day, they meet a noble person who offers Piao the opportunity to perform an important duty in the royal palace of Qin. Xin and Piao vow to be the best generals in the world one day, quitting their ways. After the heavy coup, however, Xin meets the dying Piao, whose last words lead him to action and to meet the young and soon-to-be king of Qin, Ying Zheng.
While Xin and Zheng were initially misplaced, they became camarades and set out on a road full of trials. Zheng’s goal is to put under Qin all warring nations, and Xin is trying to reach the very top of the army ranks. On the context of a relentless tactical struggle, both external and within the palace, between states and great political instability, they are working on their colossal aspirations that will forever transform history.
