The Heavenly Palace and the Demon Realm waged a great war. Seven Nuwa Stones fell from the sky, and five of them were used to imprison the Demon Lord, bringing the war to an end. The remaining two stones entered the bodies of Sui Xin and Yuan Lang, respectively, though neither of them knew it. Their master, Lu Xuan, used a divination and learned that the people chosen by the Nuwa Stones were destined for hardship, and that one of them would inevitably fight the Demon Lord and perish alongside him. Lu Xuan did everything she could to change their fate.
