so bingge never really knew liu qingge, right? he'd died before bingge came to cang qiong (or at least before he was old enough to know much about the sect outside qing qing)
so im imagining bingge shows up in svsss world, probably chasing after sqq or something weird post extras, and suddenly he comes across an ethereal cultivator facing off against some mythological beast. he remembers having trouble fighting the creature when he encountered it himself a few years after he escaped the abyss, so his instinct is to step in
only, before he can take xin mo and save the maiden (?), the cultivator rends the beast's head clean from its neck, flicking the blood off their blade with a practiced flourish
bingge is ??? (and also maybe horny? uh??)
he steps closer to get a peek and is shocked to see someone who could be liu mingyan's double, just broader, and a bit taller. he's even more shocked they aren't veiled, knowing what troubles his wife faced due to her looks
it's only after he follows (stalks) the cultivator throughout the countryside for about a week, watching them defeat demons and beasts alike without breaking much of a sweat, that he realizes this must be the Bai Zhan War God Liu Qingge, a man he'd never met in his own world, and who's death he'd handedly avenged at the behest of his wife, Liu Qingge's younger sister
the man is impressive, to say the least. he handles foes that bingge faced with only slightly less grace and efficiency, wielding his sword like an executioner's axe, brutal yet indifferent, as though the slaughter was nothing more than a duty he excelled at
he watches as liu qingge returns to cang qiong, watches as the man drops the carcasses of his conquests on shen qingqiu and that imposter's doorstep, so clearly pining and yet left alone in the cold, served with nothing but subpar tea and a glare from bingge's wretched counterpart, a wound only eased by the tempting, gentle smile of his soft shixiong
bingge begins to put the pieces together (as wrongly as one possibly could), and starts to realize (again, incorrectly) that the difference in this world must be that all his wifes-to-be are indeed husbands-to-be, and bingmei was just slow on the uptake, having only garnered one marriage thus far. he hasn't run across liu mingyan yet, so it's entirely possible her and her brother's fates had swapped here. perhaps this man's survival is why sqq didn't have such an awful reputation in this world? (he doesn't take the time to consider why that might be, not entertaining the idea he could have been wrong about his world's shen qingqiu's involvement in the bai zhan peak lord's demise)
watching this all unfold, he hatches a plan
if bingmei's pathetic self won't take the opportunity in front of him and marry liu qingge, an evidently unparalleled beauty just like his sister, then bingge will. he has never claimed to be selfless, and intends to be as greedy and self serving as possible by pursuing the cultivator who is clearly desperate for connection
connection that bingge is all too happy to provide
