Fandom #48: The Scum Villain's Self-Saving System
This, like Blue Exorcist, has also been backdated; I first began reading in this fandom in July 2020, and while it hasn't been long, I've been enjoying my dip into wuxia parody and deconstruction. If you liked isekai in theory but thought the plots had gotten stale, switching to older protagonists and a fantasy China setting might be just the ticket. Well, and it's extremely gay, which is part of the appeal. EDIT: last updated August 2023.
The majority of fic address the neo-canon couple of Luo Binghe/2nd Shen Qingqiu a.k.a. Shen Yuan; sometimes I like something totally different. If I mark a fic as the former, that's because it's the primary focus of that fic - but that pairing might still appear in other fics. That's why it might seem initially like that pairing isn't so common.
Luo Binghe (LB)/Shen Yuan (SY)
~Is it running in our blood, is it running in our veins, by half_sleeping. What if Proud Immortal Demon Way had, among its other faults, included some lazy ABO tropes?
~Reboot, by meyari. Their sex in mid-air stunt actually kills SY, who goes back in time with a new understanding of just what genre the story now was.
~Situational Reversal, by Dgcakes. SY and Shang Qinghua are sent back to their first lives. Their husbands follow them, but since they're in their original bodies while Mobei-Jun and LB are in transmigrated versions of their bodies, recognition is not automatic.
~SV Wishes, by Feynite. A truly massive series, reimagining Proud Immortal Demon Way as a gender-neutral courtly romance with polygamy/polyandry the norm. SY is stuck initially as Yue Qingyuan's neglected first spouse, and since the book bored him (I imagine this version didn't have as much worldbuilding and monsters), he never got past the initial chapters - so he starts treating LB better with no idea of what's to come.
~Tarnished Gold, by Prim_the_Amazing. SY incarnates as Gongyi Xiao, although this is not from his point of view - it's from the POV of a Binghe who just escaped the Endless Abyss, is ready to take over Huan Hua Palace, and just needs to get past his compunctions about hurting the current Head Disciple...
~The More You Don't Know, by Neery. AU in that the Endless Abyss arc never happens. LB took a sabbatical from the sect when he realized he needed to learn to hide his demonic traits. The plot thus derailed, he returns and tries to win over SY without revealing his half-demon heritage.
~Tongfang, by The Feels Whale. SY incarnates as a background character, whose life is one of nobles plotting against his survival. LB is his part-time servant, who aspires to be more (the title refers to a type of concubine).
~Uprooted, by Lethean. SY arrives in this world as someone other than Shen Qingqiu.
~What Dreams May Come, by The Feels Whale. SY and LB don't initially realize that their shared dreams are actually shared (this is during SY's time as a plant person, still underground). Almost complete WIP.
~What is Seen, by CaveteDracones. SY is caught between the System and a truth-telling artifact, and takes this opportunity to spin a story that is misleadingly honest and helps save his reputation.
Mobei-Jun (MBJ)/Shang Qinghua (SQH)
~A Well Wherein Serpents Are Coiled, by Nighthaunting. AU in that SQH has a more interesting background and a more determined personality, so he starts establishing himself as an up-and-coming badass. He has a youthful meet-cute with MBJ before the latter even acquires his title. WIP.
~A Matter of Royal Duty, by CherryBurlesque. SQH tries to help MBJ avoid an arranged marriage by pretending they're already engaged. WIP.
~An Idiot's Guide to a Happy Marriage, by Tagteamme. AU in the modern real world: office worker SQH somehow ends up in a marriage of convenience with his boss MBJ.
~The An Ding Peak Lord's Holy Cheat Sheet, by JerichoJaspersJeromeJr. MBJ has certain suspicions about his husband's past life that seem confirmed when they visit the heavens.
~By Any Other Pen Name, by Prudabaga. SQH writes erotic friendfiction, which MBJ finds (since it's all over the demonic realm) and reads without knowing the author.
~Castles Gleaming Under Starlit Skies, by ketolic. MBJ deages, just when he wanted to revamp one of his secondary homes. SQH misses every hint about who the castle is for.
~Heaven Is Here If You Want It series, by etothepii. An ABO AU, with MBJ as the omega and SQH as the alpha.
~If it can be destroyed, by Tossawary. MBJ gives SQH a truth serum shortly after he becomes Head Disciple of An Ding. It doesn't go as planned.
~If Not You, by ketolic. One of the bog-standard aphrodesiac-or-death plots targets MBJ, and his loyal retainer offers to help him through it. There's a WIP sequel, Devotion for Devotion.
~Sea Foam and Grenades, by Sunnystar. SQH leans into An Ding's reputation for spycraft. WIP.
~Servant to a Different King, by Tossawary. What is SQH had saved Tianlang-jun and Su Xiyan, meaning that he would now be the close friend and advisor of the Demon Emperor & his Empress? Cue tension with vassal MBJ...
~So You Have A Bad Day, by tagteamme. After their first time goes poorly, SQH knows MBJ visited a brothel and draws certain conclusions.
~System Override series, by Zizzani. SQH refuses to allow MBJ to die. This frightens all those present for the universe's glitching. WIP.
~The Sneaky Spy's Subtextual Self-Save-State Securing System, by Mystery_Teacup. AU, author-SQH arrived in Proud Immortal Demon Way. SQH is permitted by the System to have an escape plan after canon ends. His attempts to sneak into Iceland are complicated by the fact that he wrote something along the lines of "all myths are true" in PIDW, and accidentally became a real godlike figure.
~What I Need Right Now is Some Good Advice, by buryyourgaydar. AU, a sex-pollened SQH who is a transman got pregnant by Tianlang-jun before the real plot kicked off - actually, the pregnancy coincides with the months leading up to his ascension as a Peak Lord, so this is a problem. While the premise doesn't sound like it, it is MBJ/SQH.
Shang Qinghua (SQH)/Shen Yuan (SY)
~An Iceberg With Your Name on It, by half_sleeping. Modern AU, with MBJ & LB as high schoolers with crushes, and SQH & SY as their college-age crushes who are already together.
~Constructive Criticism, by Asymptotical. The System disappears early, SQH and SY hang out more, and much roasting of SQH's new writings occurs. It turns out SQH rather likes being insulted.
~Failing Skyward, by Asymptotical. AU, they don't leave the real world. SQH is struggling to help SY mod an AO3 fic exchange without revealing that he's the canon author.
~Felst Rose, by Asymptotical. SQH had forgotten about his discarded idea of a wandering gazebo that tries to set people up.
Liu Qingge (LQG)/Shang Qinghua (SQH)
~Bride's Last Words, by verity. On a exploratory trip in a cave, LQG carelessly touches a stalagmite and requires marital sex to survive. SQH's surprised that he doesn't want to pretend it never happened.
~Challenge Accepted, by verity. Somehow, they keep ending up in these dumb, ex-wife-plot situations. (I see a pretty clear progression in LQG: he starts out embarrassed, then intrigued that he enjoyed himself, then wondering if he likes SQH outside of sex, then realizing that he likes SQH despite his apparent betrayal, then accepting that he's in love with SQH and will deliberately trip into these dumb situations to have an excuse for sex. SQH, naturally, is oblivious.)
Other Pairings/Threesomes/Poly Groups
~Can't get by, can't let go, by JerichoJaspersJeromeJr. The PIDW Luo Binghe, who got a brief moment with Shen Yuan, is fixated on him. Eventual consensual SY/LB/Original LB.
~Cultivate: Slow Life on a Monster-Infested Mountain, by NeonGhostCat. Elements of Stardew Valley; Shen Yuan gets trapped shortly after incarnating on an isolated mountain, and eventually gets a regular guest. SY/LQG.
~Everyone Loves Shang Qinghua (My Canon Now) series, by Vodkassassin. While most of the stories interlink, and most of them are not explicit, I put this here rather than in Gen Fic because yes, nearly everyone is thirsty at least a little for SQH. WIP.
~FLORIDA MAN SHOOTS WAR GOD AND BUYS DEMON NOODLES, TRAINS SWORD-WIELDING DAUGHTER IN SWAMP, by wayward_imp. SQH decides to avoid post-canon by moving to a version of Florida. Implied LQG and MBJ --> SQH. WIP.
~Hey, share the weight a little, by Tossawary. A young Shang Qinghua (pre-name actually, as he's a young teen) meets Yue Qingyang and tries to derail the plot for his friend. Eventual SQH/YQY.
~Isn't It Pretty To Think series, by Wildehack. The problem is that Shang Qinghua wrote Luo Binghe as wish-fulfillment not only for the fans, but for himself - so in a weird way, they're the same person. Tangled LB/SY/SQH/MBJ. Room for more in this series for sure!
~It Was An Island Fair, by Asymptotical. Several AU plots piling up here: Shang Qinghua and Shen Yuan were crushing on each other in the real world, and SY arrives in the cultivation world as himself more or less, rather than Shen Qingqiu. He immediately adopts orphan Binghe, and the threads start weaving together when he and SQH give Mobei Jun the impression that he either has to compete with SY or consider a threesome. Culminates in MBJ/SQH/SY.
~The Many Trials of Mu Qingfang, by Shamelesscooper. Honestly, Mu Qingfang is a little embarassed by his eagerness to help Liu Qingge with a medical issue that requires dual cultivation to cure. It takes him a long time to realize that the attraction is mutual. Liu Qingge/Mu Qingfang.
~My Scariest Shixiong Can't Read My Mind (Thank God!), by Ehann. Shang Qinghua has always admired Shen Qingqiu. Due to a mindreading plant residue, SQQ is now quite aware of this. SQH/original Shen Qingqiu.
~Not in All Possible Worlds, But in These Few series, by Violent_entertainment. A bunch of AUs with Shang Qinghua in various couplings (some are platonic). My favorites have been the one with LQG, Wei Qingwei, Qi Qingqi, and MQF.
~Our Story's Just Begun, by aishiteru. Romantic pile-up, in which LB and SY somehow keep adding the main cast to their bedroom. Eventual additions of YQY, LQG, MBJ and SQH to the marriage (the latter two by a wife plot that has SY seething).
~put me in, coach, by tshirt. As it turns out, Luo Binghe not having a harem means that he's not initially very good at sex. Shang Qinghua is reluctantly available to advise - which starts at the basics and quickly jumps right off into the realm of kink. Shen Yuan and Luo Binghe realize that they wouldn't kick Shang Qinghua out of bed. Eventual LB/SY/SQH (as the author put it, MBJ is busy fantasizing about his minion-to-lover pining slowburn, while SQH is getting busy).
~Royal Consort Liu Qingge series, by InsanityxCreation. If Shen Yuan doesn't want Liu Qingge, the power couple of the Winter court will be happy to add a third to their marriage. Eventual LQG/SQH/MBJ. WIP.
~Sha Hualing vs. The Wife Plots, by JerichoJaspersJeromeJr. As the summary says, with two out of three demon lords married, it was perhaps inevitable that the remaining wife plots gravitated towards Sha Hualing. Eventual Sha Hualing/Qi Qingqi.
The Nigh-Mythical Gen Fic
~Achievement Unlocked, by The Feels Whale. Luo Binghe and Shen Yuan get sent on a side-quest (a la a domestic fluff bonus chapter) back to the modern world to meet/deal with SY's family.
~A Child Once, by Tossawary. Shang Qinghua gets deaged. It's impossible to hide the transmigration at that point.
~A Cloak of Feathers, by Asymptotical. AU, shapeshifters like swan-maidens and selkies existed in the real world, but since Airplane hated swans, Shen Yuan has strong dysmorphia in the cultivation world. His students come to believe in his stories about swans a little too much, and assume that someone's stolen their Shizun's cloak. WIP.
~Be Careful and Be Faithful, by Asymptotical. AU, Shang Qinghua is a little too friendly to young Binghe and the protagonist decides to apply to An Ding Peak. Bonus points for SQH's System actually being Shen Yuan.
~Dust and Broken Grains series, by The Feels Whale. Binghe decides to play nice rather than threaten his shizun during the Sower Demon arc. WIP.
~i, a demon lord, have decided to live in peace, but i'm kind of lonely?, by tshirt. Shen Yuan encourages Luo Binghe to make friends. He's not really sure how to do that. He succeeds anyway.
~i'll jump over the wall and i'll wait for you there series, by Kieron_ODuibhir. The jig is up, literally: the System is arrested by otherworldly police who shatter the masquerade for SY and SQH. Each fic is done, but there's room for more in this series.
~In Tune, by Angry_gremlin_commando. AU, when they are young Peak Lords, Shen Qingqiu starts visiting SQH Leisure House, largely because of an anonymous musician friend (who appears to have mixed heritage or demon contamination but Shen Qingqiu decides not to ask) with whom he hangs out and makes lovely duets. WIP.
~The Many Trials and Tribulations of Ming Fan, by The Feels Whale. It's almost impossible to take his shizun anywhere and get work done, Ming Fan bemoans, what with all the amorous young ladies.
~pride is not the word i'm looking for, by Tossawary. AU in that Shang Qinghua decides to take a vacation during his early years as a Peak Lord to see his baby protagonist, and guilt-trips himself into savng the Luo family; Binghe's adoptive mom and SQH end up adopting each other as family. A very slow burn fic (by chapter 13 out of 50, Binghe is still a little kid). Eventual background MBJ/SQH.
~Primary Education on Spring Mountain, by JerichoJaspersJeromeJr. Well, apparently the worldbuilding requires that Binghe has hundreds of children with hundreds of wives. If he's not producing them biologically, then someone else can father them - and the kids can arrive as nascent cultivators.
~Shen Yuan of No Relation, by Gemi. Shen Yuan incarnates in as a youth Binghe's age, with a strong resemblance to Shen Qingqiu. WIP.
~Show the Screenshots, by A_Non_ymousWriter. Suddenly select people can overhear the System Chat that SQH and SY are gifted with early in the story. WIP.
~Sit With Your Soul, by Tossawary. AU with daemons. Shen Yuan arrives as a replacement - for Shen Qingqiu's daemon. Hopefully this one will get a sequel - we leave off with SQQ and SY getting along, but no longterm plot resolution.
~Stepping Up, by Tossawary. Shang Qinghua accidentally picks Luo Binghe for An Ding.
~The Bamboo Scholar series, by Mayvn. Shen Yuan dies again, and revives in the past as a young Shen Jiu in the Qiu manor. WIP, stalled.
~The Phantom of the... Warm Red Pavilion???, by MysteryTeacup. AU, SQH gives away his weirdness in the lead-up to their generation's ascension as Peak Lords, so Shen Qingqiu demands answers and gets an accidental job of holding a "Daqin-Style Theatre Performance" for the prior generation lords (Daqin being Ancient Rome; SQH claimed he had visions of foreign futures). A hilarious WIP.
~Vicarious, by Anonymous. AU, the original Shen Qingqiu sees a physical resemblance between LB and SQH and assumes the latter is the former's deadbeat dad. WIP.
~a bonus triptych of fics with similar premises: all three deal with Shen Qingqiu coming back/possessing his body again. As follows:
-->Two for the Price of One, by Emberossa. AU: When SY shows up, Shen Qingqiu doesn't precisely leave.
-->behind a clock no longer chiming, by Jinxed_Ink. In this one, SQQ comes back after the majority of canon and is the version that went through PIDW's events. They're better at coming up with a story to explain it, and they figure out how to get separate bodies.
-->Deluxe System 2.0: Co-Op Mode!, by kitsunealyc. When SY refuses to push LB into the Abyss, the System brings SQQ back to do it; now they're sharing a body and a potential bad fate.
Weirdly Compelling Crossovers
~Catch a Falling Star, by Tossawary. An AU crossover with Stardust. Basically, transmigrators come in as stars, and Shen Yuan falls to the earth due to his interest in the plot he knows. Eventual SY/LB/LQG, but subdued (this is more of an adventure story).
~The SOLDIER General's Self-Saving Shizun, by esama. Crossover with FFVII, what if the Sun and Moon Dew Flower doesn't work and SY wakes up as Sephiroth? WIP.
~One-Winged Angel's Self-Saving System, by Terias. A response to the above crossover with FFVII. What if Sephiroth inhabits the empty Flower body? WIP.
The majority of fic address the neo-canon couple of Luo Binghe/2nd Shen Qingqiu a.k.a. Shen Yuan; sometimes I like something totally different. If I mark a fic as the former, that's because it's the primary focus of that fic - but that pairing might still appear in other fics. That's why it might seem initially like that pairing isn't so common.

-->Two for the Price of One, by Emberossa. AU: When SY shows up, Shen Qingqiu doesn't precisely leave.
-->behind a clock no longer chiming, by Jinxed_Ink. In this one, SQQ comes back after the majority of canon and is the version that went through PIDW's events. They're better at coming up with a story to explain it, and they figure out how to get separate bodies.
-->Deluxe System 2.0: Co-Op Mode!, by kitsunealyc. When SY refuses to push LB into the Abyss, the System brings SQQ back to do it; now they're sharing a body and a potential bad fate.
Weirdly Compelling Crossovers
~Catch a Falling Star, by Tossawary. An AU crossover with Stardust. Basically, transmigrators come in as stars, and Shen Yuan falls to the earth due to his interest in the plot he knows. Eventual SY/LB/LQG, but subdued (this is more of an adventure story).
~The SOLDIER General's Self-Saving Shizun, by esama. Crossover with FFVII, what if the Sun and Moon Dew Flower doesn't work and SY wakes up as Sephiroth? WIP.
~One-Winged Angel's Self-Saving System, by Terias. A response to the above crossover with FFVII. What if Sephiroth inhabits the empty Flower body? WIP.
