The energy of the two realms of light and darkness is out of balance, and war is clouded. In order to find a way to balance, Ling Yue, the princess of the Light tribe, strayed into the border of the Dark tribe and unexpectedly met Mo Yuan, the prince of the Dark tribe.
The two people, who were originally natural enemies, gradually developed feelings for each other as they got along, and discovered that combining each other could activate the legendary "Balance Crystal" and resolve the energy conflict between the two worlds.
However, the Chiyang Elder of the Light Clan covets the energy, incites racial confrontation, and vows to destroy the Dark Clan. Ling Yue and Mo Yuan must not only fight against the elders' pursuit and conspiracy, but also break the prejudice that has separated the two worlds for thousands of years.
They use love as a blade and crystal as a shield to protect peace in the collision of light and darkness. A love and struggle that spans races and affects the fate of both worlds begins.
