In the long history, there is a forgotten period of time called Dayong Dynasty. This is a fantasy world where technology and magic are intertwined, and feudal ethics and emerging ideas collide. The Dayong Dynasty was once a glorious empire, but now it has fallen into internal and external troubles. Above the court, powerful ministers are in power, and the clique wars are intensifying; beyond the borders, barbarians are watching with eager eyes, and war is about to break out. The people were living in dire straits, longing for a savior to appear.
