Western chief female knight Ersha Luoxiufeierde sees the holy war collapse and is exhausted and captured. Waiting for her is not an execution ground, but an unexpected proposal. Dragon Country prince Tang Jing uses ancient millennial rites of taking a brave warrior as a wedding to welcome her as his bride. The Eastern land praised as a barbarian evil territory turns out to be bright in rites and music with all races coexisting; the holy court she regarded like gods has a truth full of doubts and clouds. In the tearing between faith and reality, Ersha's body and mind are quietly changing. This misaligned marriage starting from a captive and a conqueror will ring the door of millennial opposition between two mortal enemy civilizations. And she, perhaps, is precisely the key that breaks the deadlock.
