So been having more thoughts about Wife SY (Links here, here and here) only instead of Bingge groveling what if? Bingmei?
SY transmigrates into wife when either a baby or very young and solves entire life and causes plot deviations from get go, since wife didn't actually have a plot and was a throw away line.
SY wins over LGJ and MBJ. These 2 have had SY from a day and will destroy everyone in this room if they are hurt in anyway. They adore SY. Both are super overprotective as SY is sickly. As half human while young the ice powers cause them to very very ill (it gets better as SY gets stronger but initially is very vulnerable)
While SY is still young some Mobei siblings think SY is getting to much favor and plan to get rid of loose end. SQH hears this and tells MBJ and SY is sent away somewhere safe while LGJ and MBJ 'clean house'. (Plus they know SY likes SQH they'll follow him around and rant at him over some books the two have read)
Safe being with SQH (As MBJ future husband, not that SQH realizes this) so SY is now on cang qiong peak.
SQH is freaking out like 'cucumber bro please just stay in house and lay low please!'
SY does not lay low, SY has been stuck in Northern palace all his/her life, they've read the entire libraries twice over. They are on cang qiong which means all the peaks different libraries, cultivator texts new books!
They'll law low and pretend to be a disciple no one will notice.
SY does not have protagonist halo protecting them and is clocked almost instantly as a half demon.... but peak lords aren't sure what to do with this very clearly sick very obviously half demon who is just reading.
LQG doesn't even try and fight he feels awkward like kicking a tiny sick puppy he can't do it. This doesn't feel fair at all, also the little demon sees him and smiles and compliments him and 'MU-SHIDI SOMETHINGS WRONG ME'
The peak lords are all confused and then realize little demon is coming from An Ding and collectively turn to SQH who is cursing out cucumber bro but bullshits that 'Oh that's just a friends cousin I said i'd look after them'. All the peak lords assume it's on the human side of SY lineage, SQH does not correct them.
SY of course spends a lot of time on Qing Jing peak(SJ got so many rare books from YQY) and of course sees protagonist and 'oh poor little sheep I can't go help him' and besides SY is disguised and wife is so forgotten it shouldn't cause any plot problems right???
Of course SY is instantly doting on Binghe helping him cultivate and learn art and music (of course they were taught it) and teaching all about beasts (a lot he will face in abyss). Binghe is beyond smitten and also so protective over SY, insisting on cooking for and helping them around because it's clear they aren't well, and also because SY praises their cooking so much and pats his head.
Things carry on until invasion, which SY is hiding in back for until Binghe nearly gets hurt and SY can't help it they jump in the way. Only for SHL to recognizes SY and freak the fuck out kicking elder skyhammer off the mountain herself. 'OH GOD YOU NEARLY KILLED THE PRINCESS OF THE NORTH ARE YOU MAD!'
Everyone bluescreening as SHL scoops up SY and nopes out calling SY PRINCESS???
This leads to SQH fleeing to North also where him and SY are just like '....so plot may be a bit messed up' cause SQH can't do invasion now... they're not sure whats happening.
Binghe is getting visit from Meng Mo and interrupts his speech
LBH: So would being demon emperor mean I could marry princess of the North?
LBH: I have no more questions reach me everything
Years later when alliance marriage happens SY is confused 'he should have married the major wives first?...why are people calling me empress? what is going on?'
