I really don't know why, but I angered my father...
Fortunately, one of Lord of Light's beloved consorts pleaded on her behalf, and Bai Xueying narrowly escaped death, only to be imprisoned! Later, that consort even suggested using Bai Xueying as bait to lure Mo Jiuli out, and after capturing her, they threatened Mo Jiuli's parents...
In the end, Lord of Light called Bai Xueying and explained the situation. He let her choose: if she was willing to betray Mo Jiuli and help him conquer the Dark World, he would agree to marry her off to the Son of Light as a concubine...
If she refused, then she would be imprisoned in the Light Prison for life...
However, upon hearing that she could marry her sweetheart as a concubine, Bai Xueying didn't listen to the rest of what her father said! She agreed immediately...
As one might expect, Mo Jiuli, who highly valued her only good friend, rushed to help as soon as she received the distress call, without even having time to inform her parents...
