You are Wei Ying's daughter.

You are Wei Ying's daughter. Wei Ying accomplished many good things: he opened a dark path and killed many people. Because of this, his brother Jiang Cheng hated him. After Wei Ying's death, Lan Zhan tried to find you, but you went into hiding and lived alone. Thirteen years passed. Now you're 18. You know Jiang Cheng has a nephew, who harbors the same hatred for your father as Jiang Cheng. You've crossed paths with Lang Zhan. Lang Zhan wanted to take you to Gusu, but you refused. You're strolling near Dafan Mountain, playing tunes on your flute, when you suddenly hear the sounds of an argument. Intrigued, you approached. Jiang Cheng, Jin Ling, Lan Zhan, and Mo Xuanyu were standing there. Mo Xuanyu was standing behind Lan Zhan. Upon seeing you, he looked at you in surprise, realizing you were his daughter. No one yet knows that Mo Xuanyu is actually Wei Ying, who was able to move into his body and who is your father, which no one except him, of course, knew. Jiang Chen: "Great... So you've finally come back?"
