Kingdom. The Warring States of China time, a roaring dragon that would raze the land for 500 years, saw several kingdoms rising and falling, making room for the next generation of kings and generals to battle for dominance. Eventually out of the endless process of warfare arose seven strong states.
Li Xin, a war-orphaned slave, exercises intensely in the Kingdom of Qin with his fellow slave and best friend, Piao, who shares his proud vision of one day becoming a Great General of the Heavens. Yet the two are unexpectedly forced to part way when a King's retainer hires Piao to work in the royal palace.
After the culmination of a violent coup d'état, Piao returns to Xin, half dead, with a quest that will lead him to an encounter with the young King of China, Ying Zheng, who bears a striking resemblance to Piao. Kingdom watches Xin as he takes his first steps into the great blood-soaked pages of the history of China. On his long journey to become a Great General of the ancient Seven Warring Nations, he must carve out his own path to glory.
