This time, she refuses to repeat her past choices and instead takes the initiative to cooperate with Lou Li, the Demon Lord, to find a way to open the Boundless Tower. As long-buried secrets gradually come to light, Yuan Yao not only reunites with her mother but also gives the Azure Dragon clan and the Black Dragon clan a fresh start. As she journeys alongside Lou Li, she finally breaks free from the fate laid out for her, learns to choose her own future, and finds a precious bond built on mutual understanding and protection.
