Let Me Go, Three Emperors Fight Five Emperors

Under nine days, in the gray fog, how many historical survivors are wandering? The Han Dynasty who died in depression, the Tang Dynasty who died of arson, the Song Dynasty who sank into the sea and made his ambition clear... As well as Rome driving slaves, Vikings holding giant axes, and Stuart operating steam engines. The aboriginal people flying into the sky and escaping from the earth seem to be consistent with myths and legends. Primitive, slave, feudal, and capital; sacrifice, Taoism, airship, and machinery. Taoist priest Yang Xian accidentally entered it. Is it the chosen one? Or dust? This is a story of world civilizations competing on the same stage, a local version of the Battle of the Five Armies.
