Let me rumble in your ask box. First of all, your Li Lun series is what made me stop from being a total ZYZ lover and THINK, and OH BOY, how wrong I was in my first assessment of the characters, so THANK YOU.
I now find Li Lun a much more compelling character than ZYZ. ZYZ suffers from both internalized inferiority complex (stemming, probably, from him being the vessel of malicious energy and blaming it on himself being a demon) and superiority complex (humans are better than demons, and everyone who disagrees is a loser). He has a borderline split personality where his inner demon ZHu Yan is in direct conflict with his humanized version, Zhao Yanzhou (the name btw is Baize Goddesses' dead brother's). The whole fallout with Li Lun is not as much because Li Lun murdered a bunch of humans, but because Li Lun represents everything that ZYZ hates about himself (being a demon, being wild, wanting freedom and lack of control, etc) and is trying to suppress.
ZYZ is very hypocritical. He pretends to be broad-minded, poised, and noble but has no problem killing a random human to prove his point or demons (like a little Pagoda demon). He is very condescending to Li Lun even though every single thing Li Lun says ZYZ is (liar, betrayer, etc) is true.
What's even more interesting, instead of trying to sort it out with the friend he had for 30k years, he spends his time trying to prevent Li Lun from establishing a connection with ZYC. Why? Because, as he said once, "I have everything and you have nothing, and you're a loser" - this is his attempt to prove Li Lun and what LL represents is the "losing" side and his own choice of becoming a human is the right one.
Now, back to Li Lun- he is wild, untamed, betrayed multiple times by ZYZ , And yet. Even though he is positioned as a villain, all it takes to bring him back to the good side is a talk with ZYZ/ZYC. Which, BY THE WAY, could've happened much earlier, and could've been handled much better. He constantly talks about wanting to kill ZYZ's friends but in the end only kills one, and only when cornered. He also inadvertently HELPS them to grow and face their worst fears.
Just imagine if ZYZ doesn't let his petty anger win and tells Li Lun that the plan is to put him back into his root and let him re-cultivate? That would prevent Ying Lei from getting killed, pull LL firmly on the good side, and potentially prevent Bai Ju from getting killed too (because now they would have 3 demons and a mountain god fighting the big bad).
Also, in the whole story, it is Li Lun who drives the changes and makes Zhuo Yichen evolve. (This is by the way why I prefer LLxZYC to LLxZYZ or ZYZxZYC). It is violent, it is painful, but in the end, it is LL who pushes ZYC out of his comfort zone, makes him confront his fear, and lose control only to regain control and autonomy, and "beat" the destiny later. And, in return, it is ZYC who, through being human and compassionate, pulls LL from the brink and shows him there's another way to deal with his emotions. They save each other, even though neither originally plans to do so.
I think, the redemption arc for LL is so convoluted because by that time he let go of ZYZ and shifted his focus on ZYC. ZYC is the character who showed him compassion and understanding. I Know ZYC said he doesn't understand LL in that alley talk- but I think he did. He was also the one who cleaned up ZYZ's mess and sorted it out with LL and the root.
I think, in the end, the two characters who experience growth and profound change are Li Lun and ZYC, and NOT ZYZ. He remains frozen/stagnant in his self-hate even though he stops being suicidal at some point. His inner conflict between the demon Zhu Yan and the humanized demon ZYZ is not resolved even in the very end.
This is also the reason why we are not allowed to see the natural progression of a situationship between ZYC and LL- because if it were given more time, we would see them drawn to each other, and ZYC realizing LL was right about ZYZ. And, of course, from the storytelling perspective, you can't let the beast steal the love of the prince away from the princess he is supposed to save.
It would also put into question the whole "destined soulmates for the win" narrative. No matter how much the show tells me that the destined ones are the true love, it shows quite the opposite- the original Baize goddess and her demon, Zhu Yan and Li Lun, ZYZ and Wen Xiao- they all were, to some extent, destined- and they all ended up in a tragedy. And they want me to believe ZYZxZYC will be any different? Even though their ending is somewhat optimistic, ZYZ did not overcome his internal strife, which would put him on a collision course with ZYC just like it put him against Li Lun decades earlier. ZYC and Li Lun are similar in that they accept themselves for what they are - and this is something ZYZ is innately against. This isn't bound to end well.
I honestly wish the show handled Li Lun's story much better. We had so many wasted opportunities- from the hilarity of the chaos LL, ZYC, and Ying Lei would've caused (just remember the episode where LL goes on a bro trip to the brothel in Bai Ju's body), to ZYZ maybe getting off his high horse and admitting his mistakes - and growing through it, to Wen Xiao realizing that just because she has hots for ZYZ doesn't mean ZYZ is blameless and always in the right, to ZYC developing even further with the push from Li Lun, to Li Lun himself dropping his disdain for humans and realizing there are bad ones on both sides. Then, maybe, his sacrifice would've been much more meaningful. Or, maybe, it wouldn't have been needed at all.
But, alas, we got what we got, and now we are reduced to writing fix-it fics )))
Welcome to the Li Lun club! After my metas, I can't ship LLxZYZ anymore, too... While I discussed the plot with my friend, we agreed that ZYZ has inner homodemonphobia, that's why he hates LL so much for no reason. As for "ZYC pushes LL towards redemption because he shows him some other way" - it doesn't work. Humiliation is not the way of showing understanding or another way out. But I agree there was a lot more potential of developing good relationship than between LL and ZYZ. And I disagree there ultimately was a single character who gets character development. ZYC began loving ZYZ almost immediately, I didn't see him overcoming his painful past (but he was the closest to the character development). LL stayed the same - he wanted ZYZ and did everything to have ZYZ by his side, his mindset stayed the same. ZYZ was stagnant, indeed. LL and Ying Lei exist in this show just to be humiliated, maybe it somehow should make us see ZYZ and ZYC in a good light, but for me it doesn't work, because I'm not interested in ZYZ's and ZYC' characters and feel narrative injustice towards LL and YL sharply.
