#nmj is not trapped in the narrative he is very comfortable here and does not want to leave

[lgbtlunaverse]

Nie Mingjue is the opposite of a man trying to escape the narrative. He's constantly being pushed OUT of the narrative and yet he keeps coming back in. He's a corpse before the story even starts he was a minor blip in the mc's life he should NOT be this deep in the narrative and yet there he is. Jgy literally killed him in his efforts to get out of the narrative himself and then nmj was like Fuck You (haunts you thereby trapping you both in the narrative forever) his brother's need for vengeance for his death is the reason the plot even exists he's so inside of the narrative he basically becomes it.

☕ possibly unpopular opinion, but I don't think lxc survives his seclusion. I think his world view is too badly shattered and he either wastes away slowly or outright kills himself.

I like—one-quarter agree with this, I think?

On the one hand, as I've said before, I do think CQL LXC kills himself. The man is just... really completely broken. And also just tried to die with JGY. I mean, I don't even think he goes into seclusion first, necessarily.

On the other hand, while MDZS LXC is also very much broken, I don't think he does die; even aside from anything else, JGY is still sealed in the coffin, and dying would be leaving him behind in a way it wouldn't in CQL—so in MDZS I don't think he does.

The part where I totally disagree with you is—I don't think it's about his worldview. It's about JGY being dead. I—think people very much want it to be about something other than that (including his grief for JGY /and NMJ/, which, still no) , and I am as ever prepared to look at a textual argument in favour if someone wants to assemble one, but honestly I think the text is pretty clear here. Throughout the temple, he's reacting and processing pretty normally—to borrow from my own previous work, here's an overview of some of his reactions to things and people other than JGY:

Obviously we see [LXC] react when he’s telling LWJ about WWX’s feelings, but even beyond that, even when he’s occupying a more background role in the narrative, we’re given his reaction quite a few times. He sighs when LWJ seals his spiritual powers (ch 100); he tends to NHS, covering with his outer robe (ch 102), comforting him when he’s disturbed at the sight of the coffin (ch 103), protecting him from SMS (after NHS frames him for stabbing him, ch. 107) and from NMJ (ch 107), and comforting him and giving him pain medicine about the wound in his leg (ch 108); along with LWJ, he’s distressed by the sound of JC’s sword-scraping technique against JGY’s music (ch 101); he tries to warn JC a couple of times when JC is fighting JGY (ch 101), cautions JL (ch 101) and later JC (ch 102) about worsening JC’s injuries, and along with JL, WWX, and LWJ freezes when JC slaps JL to the ground (ch 102); he asks Minshan why he’s being rude to LWJ, and a little later, with SMS and JL, pauses in astonishment when LWJ laughs (ch 100); he averts his gaze from and seems perhaps embarassed by the ghosts that WWX summons (ch 104); he calls out to WWX to remind him that his current body is closely related to JGY, and will therefore attract NMJ’s fierce corpse (ch 107). He actually has a couple of entertaining reactions to Wangxian being Wangxian: he coughs and tells WWX it is maybe not the best time and place for this when WWX is about to repeat “I really wanted to sleep with you,” and then later he and Jin Ling inexplicably! move their sitting cushions far away from Wangxian’s and gaze into the distance (ch 100).

And of course he reacts to JGY again and again, and—again!—is engaging and processing. Again pulling from my previous post—

And more than anything else—in what I think is a very instructive contrast—he reacts to JGY, in a way that reflects an ongoing continual emotional investment. He is, quite notably, consistently worried about JGY and unable to stand the sight of him in pain, even when he thinks he shouldn’t be. When the coffin trap goes off, and they overhear Jin cultivators wailing and a pungent smoke emerges, there’s worry in LXC’s eyes; after JGY and Minshan make it out, and JGY takes some medicine against the poison, LXC hesitates for a moment and then asks what happened (ch 103). After LWJ cuts JGY’s hand off—which means /after/ he’s taken JL hostage, note—LXC “seemed as though he wanted to help him for an instant,” though “in the end he dared not” (ch 106). When Minshan asks him for medicine for JGY, seeing how terrible JGY looks, he hesitates slightly before they’re interrupted by NMJ’s success fighting the Jin cultivators (ch 107). After they’ve defeated NMJ, he treats JGY’s wrist; moreover, “Seeing that Jin GuangYao almost passed out from the pain, Lan XiChen, who in the beginning wanted to use this to punish him, still didn’t have the heart to bear it,” and goes for the pain-relief medicine from NHS. And this is all not even accounting for his reactions to JGY either during his questioning of JGY or post-stabbing!

and

For the first, he calls out Sect Leader Jin when JGY starts in on JC after JC calls him the son of a prostitute (ch 104), although notably he does not do the same in their earlier confrontation when JGY is distracting JC in order to defeat him, only warning JC (ch 101); when JGY confesses to having burned down the brothel, he’s distressed when JGY says that it wasn’t entirely to remove the traces (ch 105); he becomes /less/ angry about the second siege and about QS when it turns out that he was operating under constraint in those conditions (ch 106); and of course, the thing he’s angriest about is JGY killing his father, “and even in such a way” (ch 106). In ch 103, looking down at the coffin he is shocked that JGY buried something that caused such horror to its surroundings, but without further information about JGY’s reasons this does not metamorphose into anger.

And there's even more! I don't want to quote all of that section because it's really long, but you get the point: before JGY dies, he's distressed, sure, but he's still processing.

And then after JGY dies, it's—

Lan XiChen staggered a few steps back from the push. He hadn’t realized what happened yet.

Lan XiChen stared at the coffin enveloped in seven guqin strings. He was still lost in thought. Nie HuaiSang extended a hand and waved it before his eyes, terrified, “… B-Brother XiChen, are you alright?”

Lan XiChen, “HuaiSang, just now, was he really trying to catch me off guard with an attack?”

Nie HuaiSang, “I think I saw it…”

Hearing his hesitation, Lan XiChen pressed, “Think it over some more.”

Nie HuaiSang, “If you ask me like that, I can’t be sure either… It really did seem like…”

Lan XiChen, “Cut out the ‘seem like’! Did it happen or not?!”

Nie HuaiSang answered with difficulty, “… I don’t know, I really don’t know!”

This was the only thing Nie HuaiSang knew to say when he was desperate. Lan XiChen buried his forehead in his palm. He seemed as if his head was about to split, unwilling to speak again.

Lan XiChen was startled, “Induce? Induce what?”

Lan WangJi’s voice was low, “Jin GuangYao’s killing intent.”

If it were the usual ZeWu-Jun, he couldn’t have failed to fathom this. But right now, it was likely he had no more space in his mind to think.

(ch 109)

Veins suddenly lined the back of the hand in which Lan XiChen placed on his forehead. His voice sounded muffled, “… Just what does he want to do? I once thought I knew him well, and then I realized I did not. Before tonight, I thought I knew him well once more, but now I do not.” Nobody could give him an answer. Lan XiChen repeated in frustration, “Just what does he want to do?”

Of the people here, some were cleaning up the scene, some were solidifying the seal on the coffin, some were thinking about how to move it safely, and some were feeling angry. Lan QiRen raged, “XiChen, what in the world is wrong with you?!”

As his hand pressed the corner of his forehead, Lan XiChen’s face was full of an unspeakable grief. He seemed tired, “… Uncle, I am begging you. Ask no further. Really. Right now, I really wish to say nothing.”

Lan QiRen had never seen Lan XiChen, a child he single-handedly brought up, look so agitated and discomposed. He looked at him, then looked at Lan WangJi, surrounded by disciples alongside Wei WuXian, and felt more irritated the more he looked. He felt that of these two of his proudest disciples who had been absolutely perfect, neither listened to him anymore and both gave him much worry.

Lan QiRen watched Lan XiChen who followed behind him sluggishly, still absent-minded, and sighed forcefully before he left with a flip of his sleeves.

(ch 110)

And then in the banquet extras, three months later:

Wei WuXian still clung to Lan WangJi’s chest, face buried at his neck as he felt the sandalwood aroma on Lan WangJi’s body grow even richer. He felt lazy all over, eyes closed, “Is your brother alright?”

Lan WangJi embraced his naked back, stroking again and again. After a while of a silence, he answered, “Not really.”

Both of the two were sticky with sweat. Wei WuXian felt an itch crawl from his skin all the way to the bottom of his heart as Lan WangJi stroked him. He twisted somewhat uncomfortably, swallowing Lan WangJi even deeper.

Lan WangJi lowered his voice, “In the years when I was in secluded meditation, Brother had always been the one to comfort me.”

Yet now the situation was the exact opposite.

Likely because Lan QiRen got a heart attack whenever he saw Wei WuXian, he simply decided not to look at him, staring straight forward. Lan XiChen was pleasant as always, holding the hint of a smile at his lips that always seemed like spring wind. Yet, perhaps because of the secluded meditation, Wei WuXian felt that ZeWu-Jun looked a bit frail.

(ch 115)

After the tasteless meal, the servants took away the plates and tables. As usual, Lan XiChen started to summarize the recent plans for the sect. But after listening for just a few sentences, Wei WuXian began to feel that he was a bit absent-minded. He even remembered two night-hunting locations wrong and didn’t realize after he spoke, causing Lan QiRen to throw a couple of sideway looks at him and puff his goatee into the air. A while later, he finally couldn’t help but interrupt him. Fortunately, the sect banquet finally ended, although somewhat hastily.

(ch 116)

So to recap—before JGY dies, he's distressed but he's still processing and reacting to things basically normally, he's got his head in the game. And then after JGY dies, he is very much /not/ processing things, he's not reacting normally, the things he's preoccupied with are entirely about JGY, LQR is like 'I've never seen him this way before.' And when we see him three months later, failing at very basic tasks he's long performed perfectly, it's the same kind of symptom—just as it was in ch 109, he seems to have no more space in his mind to think.

There's also the explicitly-drawn parallels between him and LWJ—by LQR, and by LWJ himself, paralleling LXC's current state with his own time in seclusion. And what would LWJ have needed comforting about while he was in seclusion? It's not the shattering of his worldview—it's Wei Ying.

I'm not going to go and rewatch and cap CQL temple, but the same basic pattern shows. Before JGY's death, he's functional and processing: afterwards, he's broken. I do think CQL LXC is more emotionally agitated before JGY's death than MDZS LXC is, but he's also even less functional afterwards so it evens out. If you go to 18:40ish in ep 50 (on YT, might be a different timestamp in Netflix) you can watch LXC stand frozen and stare into space and totally fail to react to anything including the conversation right next to him about his brother and WWX having run off.

I mean, I think it's also about the manner of JGY's death, if JGY had, idk, died heroically saving JL's life or something a year earlier he'd still have broken but probably not as badly? But it really is about JGY.

Tldr: I do think he kills himself in CQL; I don't think he does, even passively, in MDZS; but either way, his state at the end of canon isn't about his shattered worldview, it's about JGY being dead.
