The Legend of the Jade Sword is set during the Xia Dynasty, the first dynasty in ancient China—a time of war, chaos, and division. As the Xia strive to unite rival tribes and bring peace, a frail boy named Ji Ning Tian is born into one of these clans. Though expected to die young from illness, he defies fate and survives.

Ning Tian dreams of ending the violence and bringing unity to the land. But in a harsh world where only the strong survive, his path is full of trials. Faced with cruelty and betrayal, he must prove himself. Along the way, he finds loyal allies who believe in his vision and help him rise to claim his destiny as the true heir of the state.
