Here's The Thing. "Renheng But Blade Is Immortal And Nothing Goes Wrong" Goes Totally Against The Themes

Here's the thing. "Renheng but Blade is immortal and nothing goes wrong" goes totally against the themes set up in HSR. But it's so fucking funny.

So, Dan Feng loves Yingxing whatever. They decide to make Yingxing immortal together and then BAM no one finds out (so no big crime to be arrested for) but there's two ways to play it. Either they have to slowly gaslight everyone into believing YX was a long life species this whole time, or they have to somehow pretend this is not YX, this is some other 100% naturally immortal dude and Dan Feng just has the Most specific type ever, to the point that he basically got his exes twin but immortal with a cooler haircut.

And with the gaslighting idea - I think it could work. No one's gonna notice that YX isn't aging for at least a few years, probably more since everyone they know is long-life and they likely have a warped perception of how regular aging works. So DF & YX just gotta wait like 5-10 years, slowly dropping hints that "oh yeah can't wait till our 150th anniversary!!" And Jing Yuan is like "... Hmm is that normal? That's probably normal?".

Cos also. Who's gonna mention it? Like it's gonna take so long for anyone to notice, is Jingliu gonna eventually sit them down like "you did a big sin didn't you" and then YX and DF just play dumb: "what??? Jingliu what are you on about? Is Mara eating all your memories of YX definitely being immortal this whole time?" So that's not good for Jingliu's mental health but whatever.

Anyway so Dan Feng and Yingxing have successfully scammed everyone but DF is still definitely the High Elder and absolutely no one wants him to be dating this guy. Also the dragon heart is missing cos it's in YX's chest and surely the Preceptors would check up on that? Like a renewal service? Some sort of 200-year check-up? Does DF have to take his bf with him so the aura is nearby? It's just a game of "how dumb are these guys?" Until all those preceptors reincarnate into ones who DF can convince "oh no the High Elder is supposed to give the dragon heart to their beloved. Yeah it's a ritual. Oh the immortality uh no Yingxing had that forever obviously".

Eventually YX is gonna get stabbed and he's definitely more immortal than everyone else. More gaslighting ensues probably, cos otherwise it's like?? He's just an abundance monstrosity (Jingliu is seeing red rn) and Jing Yuan has sussed it out at this point but yknow he likes YX; he prefers him being alive than dead. Jingliu is gonna stab YX for being an undying monstrosity and JY steps in - "nooo don't you know I mean ig your parents never told you but if uhhhh you suck enough dragon dick this is totally normal -" and anyway Sanctus Medicus get a lil fetishy sex crazed from that conspiracy theory.

Then later DF has to be reborn which is sad, but I like to think YX just takes like. A gap year from their relationship. He's a divorced old man he deserves a mid life crisis while DH gets the "plss don't fall in love this idiot guy again" speech from the other Vidyadhara but it's working like reverse psychology, DH is all "pshh I'm way too put-together for that!!" And anyway YX is still a hot piece of ass so DH fails immediately.

One day DH gets a dream memory about the whole sinning part of their relationship and has to come to terms with That™ meanwhile YX is sipping a mimosa while he's having a moral dilemma. "No babe it's fine it's like. Yeah it is a hellish sin but it's cute that you're so worried about it. No they can't try us for crimes we did so long ago don't worry" meanwhile JY is still dealing with the paperwork nightmare from YX's birth certificate definitely not being that of a long-life person's but ehh.

Basically fluffy unproblematic renheng where no one gets amnesiaed or tortured is great and good even if it laughs in the face of canon.
