I'm currently swamped writing my big bang entry but I've had this idea for a lxc x wn soulmate au for a few days:
-lwj sees a sketch in one of wwx's notes that he recognises and he's like WHAT IS THAT. Wwx admits that it's a soulmark from one of the people at the burial mounds. Lwj says that it is also the soulmark of someone from gusu. He agrees to bring them to the burial mounds, and wwx agrees to introduce them to the person.
-lwj shows up with lxc to find wwx next to a very nervous wn who almost faints when he sees lxc. "that is the most beautiful man in the world, are you kidding me? There must be a mistake"
-wwx insists that there isn't, that wn is more than good enough for lxc. They compare the marks and it's unarguable that they are the same.
-lxc goes all "oh, my soulmate is one of these people? That means i must take all of them immediately into the cloud recesses :))) sorry i dont make the rules your fated one is a very big deal im obligated to do this :)))" while internally being like "thank fuck i have a politically sound excuse to help these people, no one can tell me shit, also he's kinda cute even if he's kinda dead". lxc isn't picky.
-for the first time since they broke up, nmj and jgy agree on something, and that something is "xichen, what the fuck"
-wangxian pining in the background. Lwj asks wwx about his soulmark (even tho that is super forbidden by the lan rules) and wwx says that a dog bit his ankle and ripped most of it off when he was young, and he doesn't remember what it looked like. Lwj is internally like "my soulmark is in my ankle, could it be..." But doesnt say anything bc he is a cowardly little shit.
-once everyone has moved into the cloud recesses, lxc talks to wn like "i dont expect anything from you, your family will be safe regardless, but i would like to at least be friends" while wn is silently chanting "top me, top me, top me" in his head. Lxc is just as thirsty, he's just good at hiding it. They are adorably cute together and they take things slow, going on dates, it's a big deal when they hold hands for the first time, etc. At some point they kiss and they have sex immediately after like oops how did this happen.
-maybe the other sect leaders (read: jgs and the boys (the boys being ouyang and yao)) are like "ok i guess the wens are untouchable now but what about wwx? He's still a menace! He still has the amulet! He still..."
-lwj: well he happens to be MY soulmate and im the brother of the sect leader so you all can go shut the fuck up.
-*crickets in koi tower*
-lxc, wwx, wn, wq, jyl, jc, you, me, my mother: WHAT
-Lwj explains to the pertaining parties afterwards that they can just pretend its true and it will save wwx if everyone goes along with it
-wwx is all like ":( but what about your real soulmate.... :( this will make it more difficult for you to find them... :( I dont want to cause you problems with them..."
-lxc and jc facepalm. Lwj insists that it doesn't matter. Someone (lxc) suggests that maybe ;) wwx should move into the jingshi ;) to make it more believable ;););)
-lwj: brother why are you like this
-lxc: *already gone to bang his brand new husband*
-wangxian share a bed and pine and eventually wwx sees lwj's soulmark and it triggers the memory of seeing his own soulmark when he formed his golden core when he was a child and they have a "it was you all along!" moment....
-then they fuck. The end.
I might write this into a proper fic eventually...we'll see.
