"Si Teng" finale, I believe that many viewers after watching, feel that fanwai is more like the finale, the 30th episode is just a sample film.
In Fanwai, when he grew up, Xizhu wanted to look for Qin Fang, and as a birthday gift for his 20th birthday, he chose to travel alone and found Qin Fang and Si Teng in the depths of Cangcheng Mountain. When he saw Qin Fang and Si Teng, it seemed that the result was not so important, and Xizhu also chose to give up looking for answers and walked out of Cangcheng Mountain.
This ending can be said to be very good, everyone has found their own home, Qin Fang, Yan Furui, Si Teng, XiZhu and so on.
But in the middle of the ban, there is a fascinating detail, which makes people very curious, why as soon as you enter the temple, Xizhu changes its appearance, and why is this?
In fact, from the previous plot and the dialogue of Sito Nishitake, we can infer that Nishitake is one of the sub-bodies of Sito.
After fighting qiushan, Si Teng relied on Qin Fang's blood to gain strength, and it took several years to separate out of Xizhu. Because of his eagerness to grow up and recognize Qin Fang, Si Teng had to use energy against the sky, thus losing his vitality.
When he learned that Kong Jinghua was also a member of the Yuan clan, Si Teng made a deal with Kong Jinghua, but Si Teng still did not seize Kong Jinghua's power, and let Xizhu become a normal person.
At this time, although Xizhu was a split of Si Teng, he did not have the ability of the Yuan Clan, so he was an ordinary little girl. But it was this move that allowed Si Teng to regain his strength, but he still needed to recuperate.
Some people may ask, isn't Si Teng possessed by Nishitake? In fact, it is not, from the surface of various signs, Xizhu is only one of the splits, just like when Si Teng differentiated into Bai Ying.
As for why the split is Xizhu in the form of a little girl, rather than Bai Ying in the form of an adult, it is actually related to Si Teng's experience.
When Si Teng just changed into the Qi Clan, it was the shape of a little girl, Qiu Shan took her away, from childhood to her very harsh, light scolding and heavy beating, Si Teng did not have a happy childhood, which is also something she has never been able to forget.
This became an obsession in her heart, so the little girl Nishitake was differentiated, just to relive a childhood, but who could have imagined that Nishitake's life at the beginning was not good, which made the original amnesiac Xizhu have the memory of Sitten.
In a sense, Nishitake is actually the third "Sitō" and the other "Bai Ying", because they are both splits of Sito.
Thinking of Bai Ying's face change in front, then Xizhu's face change is not so understanding. So why did Nishitake change his face after entering the temple, and after leaving the temple, he returned to his original state?
In fact, this is a bit like the tunnel in "Spirited Away", the connection is probably two worlds, Nishitake saw Si Teng, as if the split body saw the body, but it is two independent individuals, so the appearance is different.
But Xizhu chose not to go after the past and re-live, returning to the original appearance, in fact, he was afraid of suddenly changing his face to frighten others, after all, it was a terrible thing to see familiar people suddenly change their faces.
In fact, the setting of Xizhu changing faces is really good, so that many viewers who think that Xizhu is Si Teng can see that Xizhu is just another "Baiying".
