What Are Popular Mo Dao Shi Fanfiction Tropes And Pairings Readers Love?

WangXian dominates, no surprise. Their dynamic lends itself to established relationship fluff, jealous Lan Wangji, and 'Wei Wuxian is oblivious' tropes. Canon divergence is huge because the original story leaves so many painful points open for revision.

Jiang Cheng gets a lot of gen fics focusing on his trauma and reconciliation. Nie Huaisang-centric fics often turn him into an unreliable narrator or a scheming protagonist. For pairings beyond the main, Nie Mingjue/Jin Guangyao is the big angsty one. People also like exploring Lan Xichen's isolation post-canon, often paired with someone like Nie Huaisang or Jiang Cheng.

The fandom loves taking the rigid cultivation world rules and either embracing them for drama or completely subverting them in AUs. That tension is where most stories live.

Popular tropes? Let me just list what I keep clicking on. Fix-its, always. The 'Wei Wuxian survives the siege' scenario has a thousand variations. Marriage of convenience, especially for political alliances between sects, forces characters into proximity and they have to deal with it. Amnesia plots, where someone forgets the past and everyone has to tiptoe around them.

Pairings beyond the main one… Jin Guangyao and Nie Mingjue have a brutal, fascinating dynamic. It's never healthy, but the tension is incredible. I've seen some really moving Jiang Cheng/Nie Huaisang stories where they bond over shared grief and responsibility. And there's a small but persistent stream of Wen Qing/Wei Wuxian fics that explore the 'what if' of the Sunshot campaign differently.

A trope that seems to be fading a bit is the high school AU, but it's been replaced by more inventive modern settings. Coffee shop AUs are still a classic, but I've seen supernatural detective AUs, rock band AUs, you name it. The core appeal is taking these deeply historical, tragic characters and plopping them into a world where they can just… be happy, or at least face different problems.

the sheer variety is wild. The most common pairing is obviously Lan Wangji/Wei Wuxian, but the way people approach it splits into distinct lanes. There's a massive amount of post-canon domestic fluff—stuff about them raising A-Yuan, bickering over Gusu rules, that kind of warm blanket comfort. Then you've got the complete opposite: intense canon-divergence where Wei Wuxian never died, or where he returns much earlier. Those often get into political intrigue the novel only hinted at.

A trope I see constantly and will never get tired of is 'soulmate-identifying marks' AUs. It's like the fandom's favorite sandbox. Sometimes Lan Zhan has Wei Ying's name etched on his skin, sometimes they share a red thread, sometimes they dream each other's memories. It just fits the whole destined, fated romance vibe of the original so well, even if it's a modern setting. The other huge one is time travel fix-its, usually with Wei Wuxian going back to his teenage years armed with future knowledge. They're basically power fantasies, but the good ones really dig into the regret and the second chances.

Less popular but still thriving are the rare pairs. Nie Mingjue/Jin Guangyao has a dedicated, slightly masochistic following for all the angst potential. Jiang Cheng-centric gen fics exploring his leadership or his relationships post-canon are often really well-written. And you can't forget the Xue Yang/Xiao Xingchen dynamic—it's a tragedy magnet, but people keep writing it, maybe to somehow heal that unbearable ending.

Honestly? The WangXian saturation is real. It's the backbone. But what I find more interesting are the tropes built around the supporting characters. There's a whole subgenre of 'Jiang Cheng adopts an orphan' fics that are clearly about giving him the family he lost. Or 'Nie Huaisang's secret mastermind' stories that turn him into a POV character for political thrillers.

A weirdly specific trope I love is 'Wei Wuxian teaches the juniors'. It combines found family with him finally getting to be the fun, irresponsible teacher he was meant to be, and Lan Wangji just sighing in the background. Also, modern AUs where the cultivation sects are corporations or university departments are low-key genius. The Yiling Patriarch as a rogue tech CEO? Jin Guangyao as a slick, backstabbing middle manager? It works suspiciously well.

I'm less into the extreme hurt/comfort or mpreg stuff, but it's definitely out there for those who want it. The fandom's big enough now that every niche has its corner.
