Everything about Chi Wen/Long Shen is Fake
Stolen would not be the right word. Borrowed? But I will add stolen beacuse there is one instance where it is.
Disclaimer: SPOILERS! Also, this is not a critique on TJR (my favorite actor for last year and even still now). If you like (fake) Chi Wen, scroll away.
By now, many theories have emerged, then there is also the series itself progressed to some plot points where we can safely draw conclusions.
1. The post of Long Shen that Chi Wen occupies? Not his. I will admit, from all the info that we currently have, his decision to hold this position is nothing less than a sacrifice. I hate the man but I will give him credit.
2. His name itself. His own original name is Ji Ling? The same name that he decided to give away to a version he created by putting a part of his soul in a doll. Not a puppet, because puppets do not break control of their owners and ask about the acknowledgement of their existence.
3. His powers. Whenever he uses a power, he takes on a certain appearence. That appearence likely belongs to the being whose powers he is using.
4. His memories of outside world. Because they are not his. They will never be his. He himself acknowledges this by acting all wide eyed when seeing the outside world for the first time. The people dancing. The leather left to tan. Petting a peacock. He is fascinated. So even if he recieved Ji Ling's memories, he never got that experience.
5. His romantic relationship. Because it was Ji Ling who engaged with Lu Wuyi. And proof of this is Lu Wuyi herself who asks if he is Ji Ling or not. She is not interested in other answers. She is not interested in Chi Wen, the old dragon, but Ji Ling, the cheerful boy who met her. (Which will change too, but as of right now it is what it is)
6. His face. Apparently the fox took on the appearance of one person he failed to heal.
So Chi Wen/Long Shen is a person who lived a long life, but it was a borrowed life. Borrowed name, borrowed face, borrowed powers, stolen memories, stolen experiences. Borrowed meant that he took it with permission/acknowledgment of the owner, or they were could not be impacted by it in the first place (the case of his appearance). Stolen meant he either forcefully took it (Ji Ling), or took it without their knowledge or acknowledgement (Ji Ling). Does that makes him pitifull? Yes. Does it makes him more prone to self flaglation or putting himself down? Yes.
Will it make me like him? Nope. You are welcome to do whatever you want with this info🙂
