Youzhou, this frontier place in northern China, is a legend forged by blood and fire. Here, the flames of war are endless, cavalry tramples everywhere, intrigues and swords are intertwined, the blood of Hu and Han are mingled, and heroes emerge in large numbers; loyal bones are buried under the city walls, war songs echo in the passes, dynasties change on horseback, gold flows on the trade roads, there are generals who lay down millions of corpses with angry orders, and the city-state overthrown with smiles. It is like a wordless heavenly book, describing the desolation of the frontier, like an epic of killings, hiding unsolved mysteries, and the secret history of Youzhou is waiting to be revealed.
