Disciple Shen Yuan (during disciple Shen Jiu era) who accidentally became the Divination Peak's head disciple bc he worked so hard and used all his meta knowledge, just so he could make a video-based divination system that shows the future. The Peak Lords were all appropriately impressed and this seals Shen Yuan as the next Divination Peak Peak Lord. A lot of pre-canon problems get solved. It becomes a world-changing invention.
Shen Yuan made it just to watch the endings of all his favorite animes.
Just. The hilarity of Peak Lord Shen Yuan becoming this mysterious genius Seer, sought after by the entire cultivational world. And then he just locks himself inside, pretending to be "prophesizing" or something. He's a full blown NEET at this point. He completely misses Shen Jiu's entry to the sect bc he was too busy "dvining" the next episode of Frieren Beyond the Journey's End. The next time he comes out, its with some vague words of valuing time spent with your peers.
The Qing Generation Peak Lords immediately listens to him and are now doing constant meet ups as the equivalent of team bulding exercises. The Shen Qingqiu rumors get solved. Shen Jiu is appropriately wary of this seemingly all knowing Peak Lord whom everyone listens to. And yet he also considers. Someone who can see the future? Someone who can SPEAK of the future they see and CHANGE it? Oh? Someone who can see all possible threats? What do you mean he can also divine your past? Past as in blackmail material?
Shen Jiu, in a fit of genius proving his right to be called the sect strategist, decides he'll have to test tf outta Shen Yuan to see if he can trust him (and sj is also low key terrified and hateful bc here is someone who can ruin everything he's ever done and he will NOT just let it be tyvm) and so Shen Jiu just. Does some minor (extensive) background search. And tries ro get Shen Yuan to snap. Yeah, that's right. Just annoy the scary all-seeing dude.
Shen Yuan eventually gets super annoyed, his inner internet troll has been desperately struggling to get free for YEARS, and now here's a convenient target who totally deserves it. Shen-Shixiong you total prick, why do you keep digging up everything about Shen Yuan!
So. In a fit of similar genius spiked with way too much pettiness, Shen Yuan goes "You little prick, lets see how you like it when YOUR privacy gets invaded!" and promptly plays a random scene from Shen Jiu's future ala projector style while they were in a Peak Lord meeting.
Shen Yuan made sure its nothing distressing or embarassing, he's petty not cruel! Except he did this by just doing a routine surface level scan of the emotions involved, and it was on "happy." Shen Yuan, a fuerdai who never really knew about Shen Jiu's past, just assumed it'd be a basic scene of maybe having a good meal or talking to a friend or something. He did NOT realize how fucking rare "Happy" is for Shen Jiu.
The scene that plays is a marriage.
Two figures decked in regal red marriage robes are in a bow in front of each other. The unmistakeable Grand Hall of Cang Qiong swathed in tastefully luxurious decorations surrounds them. There are also a lot of other damning details.
Qing Jing Peak's logo is embroidered onto the billowing ribbons. Paired with Divination Peak's own logo.
The two figures stand.
Its Shen Jiu and Shen Yuan.
When future-Shen Jiu actually smiled at future-Shen Yuan (who looks disgustingly in love wtf) and started leaning in for a kiss, present-Shen Yuan violently slams the divining tool off.
The loud slam is followed with a damning silent moment. That, unfortunately, lasted only for an actual moment.
Someone clears their throat.
Its Qi Qingqi.
She has a shit eating grin on her face. Besides her, Wei Qingwei's expression is slowly starting to match. Around, the other peak lords are either too invested, or carefully avoiding looking at him and Shen Jiu.
Shen Yuan very, very carefully does not look Shen Jiu's way.
"So..." Qi Qingqi begins. "Interesting divination there, Shen-Da-Shixiong, Shen-Er-Shixiong." Her words practically drip with insinuation.
Oh God. Oh Fuck. Fuck no.
Side Notes:
Shen Yuan's eyes glow a beight system blue whenever he "divines the future"
Shen Yuan wears a fortune teller outfit, meaning he's typically covered head to toe, complete with a veil.
Shen Yuan CAN actually see the future and show it to other people, either ala projector style 2d view of his choosing. or a complete 3d (like a pensieve in hp)
I'm a firm believer that Shen Jiu is not gonna be normal about Shen Yuan. In a scenario where they share a body, he would hate it at first. There is some kind of parasite in his mind, and he can't get rid of him. He hates it when something is out of his control.
However, it is also comforting? There is someone who can't leave him, who sees all his vulnerability and rot inside his soul, but he's still there, no matter what. He will stay by his side.
Even if they fight, Shen Yuan tingles something in his brain with his different worldview, especially as this brat believes that people aren't born bad. Too forgiving.
In the beginning, he wants him to be gone asap, so he tries to find different ways to get rid of him. But the more he spends time, the more he understands that he should stay he is too dangerous to let go. Obviously, he knows Peak Lord's secrets, so Shen Qingqiu can't let him do unguarded. He's safer here, with him.
The boy has so much vitriol but is still too naive to notice other people's intentions.
So we end here with Shen Jiu's weird situationship with Little Bodysnatcher and the weird codependency they establish meanwhile.
disciple!luo binghe finding out that shen qingqiu has a "companion" named shen yuan, who is sunshine personified and who can't seem to stop cooing over binghe, calling him the cutest little lamb and giving him food and an actual place to sleep and a real cultivation manual. binghe falls head over heels.
no one knows the actual relation between shen qingqiu and shen yuan, whether they are brothers, lovers, friends, just that shen yuan lives in the bamboo house and shen qingqiu is notoriously possessive about him and will resort to violence.
one day binghe witnesses shen qingqiu coldly rejecting shen yuan's attempt to cuddle and vows that when he grows up, he will spoil shen yuan as he deserves (shen jiu didn't actually reject his a-yuan, shen yuan was trying to distract him to steal sweets out of his sleeves and shen jiu is trying to make shen yuan eat actual food).
anyway, shen qingqiu eventually realizes that not only does he have to ward off his fellow peak lords (yue qingyuan stop buying him more candy and liu qingge stop leaving disgusting corpses on his porch!!), but the threat is coming from inside the house peak as well, and he kicks luo binghe into the abyss not because he's a demon, but for trying to poach shen yuan.
