A TV series about the legend of the sword and the chivalrous man, I don't understand some places.

In fact, the fairy sword talks about fate, and many things are doomed, so your first question will be answered.

1 Ten years ago, it was the little demon who saved Linger, but it was the little demon who crossed back after Linger was injured. Xiaoyao in Linger's memory is Xiaoyao, but it is Xiaoyao a few years later. The real beginning of Xianjian is that Li Xiaoyao is still a punk, so Xiaoyao and Linger are destined to become attached.

Linger cast spells in the hope that she and Xiao Yao can return to the life of loving each other in Fairyland. Then she cast spells because she found that love can't be forced, and such a small demon is not really a small demon, so she decided to change him back and start with Xiao Yao again.

3 Xiaoyao Linger's nose has shown that he has a good impression on Linger. Although the forgetting method made him forget what happened in Fairy Island, maybe that feeling still exists. In fact, this just confirms the theme of Xian Jianyi, "Destiny". Even if Li Xiaoyao adopts the method of forgetting, he will fall in love with Linger, and then things will happen as usual.

At that time, Linger had accepted that she was a descendant of Nuwa, and decided to fulfill her responsibility to save Nanzhao people. She also knew that this trip was dangerous, so she decided to break up with Xiaoyao, let Xiaoyao give up and not let Xiaoyao accompany her to take risks, so that she could endure it again, but after all, she was a girl, and it was not a pleasant thing to watch her lover go in and out in a romantic place. As for smiling at each other, it shows that Xiaoyao has understood Shine's heart.

Having said that, the answer to this question is already obvious. Free and unfettered is not just a lingering responsibility, but full of love.

6 this ... may be the need of the plot.

Xian Jian said that apart from fate, this is a question of great love and responsibility. Nu Wa's descendants all have responsibilities that they must shoulder. In the face of great love, they have to sacrifice little love, so there is such a feeling of entanglement between shining and freedom. Xiaoyao made Linger, and so did Linger and Yueru. Every positive figure in Xianjian No.1 has made sacrifices for this great love to a greater or lesser extent.
