Protective Jiang Yanli Headcanon:
I have this idea in my head where Jiang Yanli is a bit more protective and political than in canon.
In my head when Wei Wuxian comes to Lotus Pier Jiang Yanli latches on to him just as he seems to latch on to her. Here is someone who needs her, who to a certain degree relies on her. In many ways Jiang Yanli sees Wei Wuxian as her child because she is the one that raises him.
The political side comes in regarding her engagement to Jin Zixuan. Wei Wuxian isn’t treated well by Yu Ziyuan and Yanli knows that her father won’t step in to stop Yu Ziyuan from hurting Wei Wuxian. So Yanli comes up with a plan. Yanli plans to take Wei Wuxian with her to Koi Tower.
Of course this brings its own set of difficulties. She will have to convince her father to let Wei Wuxian go, the toxic environment of Koi Tower, and the fact that Jin Zixuan resents their engagement.
Jiang Yanli schemes. The easiest to overcome is Zixuan’s dislike, she just needs to make him see her as a victim or ally rather than an enemy. This idea leads to her ultimate plan.
Yanli is going to poison herself while she is at Koi Tower. She is going to lay the blame on either one of the female Jin disciples who acted out of jealousy or one of Jin Guangshan’s cronies with the excuse that they think closer ties with Yunmeng Jiang will cause a decrease in their power (or something similar). The point is that she needs there to be an initial panic, investigation, and ultimately while someone will be caught Yanli needs there to be doubt in her parents’ minds as to whether Koi Tower is safe for her.
At this point Yanli will request that Wei Wuxian comes to Koi Tower and acts as her bodyguard. She knows that with the recent poisoning attempt her father will be weak to her request and more likely to grant it. It will be even more effective if she can get Jin Zixuan to request that Wei Wuxian come to Koi Tower to look after her because her parents can’t deny a sect heir easily.
Jin Zixuan will make the request because after Yanli poisons herself and her fiancé comes to see her she will tearfully request that he bring one of her brothers to Koi Tower. She will say she is afraid and that she misses her brothers. She will act weak and pitiful to soften Jin Zixuan’s heart to her. Jin Zixuan will see how Yanli was poisoned by someone of his sect and see her as a victim. He will pity her and thus accept her request and bring it up to her parents.
Of course Jiang Cheng cannot come to Koi Tower he is the sect heir and must stay in Yunmeng Jiang where it is safe. Wei Wuxian however is much more free to come to Koi Tower and look after his Shijie.
Jiang Yanli is happy. Months of planning, carefully building up an immunity to poison, and gathering the necessary ingredients have all payed off. As for the toxic cloud hanging over Koi Tower, there was already one poisoning attempt who is to say that there won’t be a second and that Jin Guangshan is the unfortunate victim this time. Of course with Jin Guangshan dead and Jin Zixuan the new sect leader Wei Wuxian will need to stay at Koi Tower indefinitely to protect Jiang Yanli.
I’m not sure how this ends. Maybe with Jin Ling’s birth or maybe with Wei Wuxian marrying Lan Wangji. I don’t know how much Jiang Cheng or Wei Wuxian know about Jiang Yanli’s plan. I am aware that Jiang Yanli can be considered OC. In the end this is just an idea that I had and wanted to share. I hope you like it!
