Ouyang Yue, an orphaned girl who was swaddled as a baby, disguises herself as a boy and holds together the crumbling Dongshan Kingdom as it faces off against Minyue.
Lu Xingming, a mysterious escort who has spent years traveling into the mountains to transport supplies, met Ouyang Yue deep in the mountains when they were young. They grew up side by side, fell in love, and came to know each other inside and out.
Later, Minyue's troops lay siege to the capital, and the Central Plains intervenes to mediate.
In the end, forty thousand survivors leave their homes by the coast and in the mountain forests, and the kingdom gives up its name.
The entire population migrates to the fertile lands of the Central Plains. A century of war and old grudges finally gives way to peace across the land.
Through a fated childhood romance, this story depicts a thousand years of cultural exchange between Han civilization in the Central Plains and the indigenous Ou-Yue people.
