I don't know if the subject has seen "Xian Jian Yi", but everyone who has seen it knows that the heroine of this TV series is Zhao Linger. Because the whole TV series happened when she returned to Nanzhao, Xiaoyao promised to accompany her back to her own country. Yueru is a lifelong friend they met on the road.
Perhaps the subject probably saw that in the middle of the process, Xiaoyao said to Yueru, "Eat until you are old, play until you are old", such an oath. However, Yueru, Xiaoyao and Linger will be separated forever in the Lock Demon Tower in Shushan. He loves freedom deeply, and he is content with the simple hope that he can be happy. So when she decided to be the last person to die, she said, "I didn't expect that I was so old." Presumably, everyone who sees this place will cry with Yueru. She can risk her life for love and happiness.
However, everything is not over yet! Linger and Xiaoyao have to go back to Nanzhao and save thousands of people. Xiaoyao finally remembered his past with Linger, and the word "Ling" in his hand finally shone. It's just that Yueru can't fight them anymore!
The conspiracy behind it is about fighting with the leaders of Yue Bai. Linger finally sacrificed herself, leaving a happy person to live in this world.
It is the heroine who falls in love with the hero, the main story line is the heroine, and it is also the heroine who finally exits to end the whole TV series, so the heroine must be Zhao Linger!
