#please just imagine the shenanigans that not-really-human xiao-su would cause bc he wants to spend a bit of time with his human's human

Dumb SVSSS thought of the day is Xuan Su being one breakthrough away from cultivating a human form and making its (his?) newfound ability to speak aloud to other people everybody's problem.

Unity of the Sword cultivators give more of themselves to their bonded blades than people cultivating other paths, because they have to cultivate together with the sword, as partners. It's both a blessing and a curse, making their swords more... aware. It's not unusual for Unity swords to ascend with their masters or to cultivate humanoid forms to become something like a platonic life partner.

Xuan Su is an old blade. A powerful one, expertly if eccentrically crafted (what kind of cultivator would choose a zhanmadao when a jian is so much more ethereal and versatile?) and wielded by dozens of prodigiously talented cultivators before.

Each one of them set it aside, finding it too heavy and unwieldy for their ambitions. Each and every one of them died for it. It could feel through the bond as they each fell, the lighter, sleeker blades they replaced it with crumbling like paper under the weight of the destinies they all bore.

If it stopped calling out to young prodigies after its history of losses things would have been... much the same, probably, because Yue Qi has heard about the power of Xuan Su before he stepped foot in the sword hall, but there might have been a chance that he might have heard the call of a sword more suited to his level of cultivation, one that could have grown organically along with him.

The problem is, Xuan Su keeps calling out to new wielders and no amount of warning from Wan Jian's masters could convince the ambitious prodigies to give up on the chance to be the one who carried the famed Xuan Su to ascension.

After losing too many of its people, however, Xuan Su no longer knows how to bond normally. It clings too hard, hooks its metaphorical claws into its cultivator's soul, crawls through their meridians until there's no boundary left between them.

The last three people who tried to take it up didn't live long enough to unsheathe it.

For good or ill, Yue Qingyuan will be the last one to ever wield Xuan Su. It will either ascend with him, die with him or Wei Qingwei will throw it in the Wan Jian forge where the cursed thing deserves to be if it manages to outlive zhangmen-shixiong.

The thing is, however, that an old sword doesn't necessarily mean a mature one. Xuan Su wasn't wielded enough for its spirit to have matured fully. The only cultivator who even entertained it past the first few months of realizing that fighting with a zhanmadao is an unwieldy affair, that they could never become the picture of divine grace hauling around a blade that gave some polearms a run for their money, has been Yue Qingyuan, so most of Xuan Su's personality comes from him.

A thousand years worth of guilt and abandonment issues mixed with whatever traits it borrowed from semi-feral ex-slave teenager Yue Qi when they bonded does not make for a pleasant personality. It would remind Yue Qingyuan of a young Xiao-Jiu, expect Xuan Su has a brand of unashamed bloodthirstiness that can't be replicated by anything that's not made of 5 feet of sharp-edged murder.

It's not all bad. Xuan Su mourned with him when they though Shen Jiu was dead and rejoiced when they found him again. It has been trying its best to help Yue Qingyuan fight his heart demons so he could confess to Shen Qingqiu, even when it has heart demons of its own. They are beyond compatible in the physical and spiritual sense, granting Yue Qi the almost inhuman strength he became famous for. The mental component of their cultivation stagnates, however, because they are trying to split their attention between dealing with Yue Qingyuan's guilt and Xuan Su's abandonment issues and they are getting nowhere.

It's Shang Qinghua who accidentally gives them the push to pick one or the other. ("All right, enough!" Shang Qinghua claps his hands and freezes the dozen frantic An Ding disciples almost coming to blows about which one of their three separate crises should get the most resources. "You," he points at a kid with a missing front tooth. "All resources to your problem. And when that's done, then to his,-" Points at another child. "- and then hers. This way all of them will get solved on time and they will get solved better because you don't spread yourself thin trying to do three different things requiring full focus at once.") They decide to address Xuan Su's bottleneck because it's easier: Yue Qingyuan has already proved that he would not abandon it. They will ascend or die together.

They don't expect the backlash from its breakthrough to knock Yue Qingyuan out for several weeks (it's the bond stabilizing, finally, but his body and core need time to grow accustomed to only having his qi and his life force, all contained neatly within him as it should have been all these years). Weeks while Xuan Su is left alone on the peaks, unsupervised and without anybody knowing that it currently wears the form of a fourteen-year-old boy.

So of course the first thing it (he?) does is slip away before anyone could identify him and goes to Shen Qingqiu. The plan is simple: chew the man out for making Yue Qi sad all these years and then tell him what went down in the caves so he forgives Xuan Su's human and they can all be a happy family together! (A lot of its previous wielders sought fame to be allowed to wed various people they would not be able to marry otherwise, so Xuan Su might have acquired a passing interest in romance. Xuan Su approves of Yue Qi's choice, Shen Qingqiu is a sharp, very sword-like human and Xiu Ya is a very nice, well-balanced sword, but they really keep dragging things out way too long.)

Except Shen Qingqiu doesn't believe that the suddenly appearing feral teenager on his peak is actually a sword spirit. Swords cultivating human form are the stuff of legends and Yue Qi is far too down-to-earth for any of that nonsense. So clearly this Xiao-Su is an orphan his idiot Qi-ge has adopted; he's certainly feral enough to be one. No idea where Yue Qingquan has hidden this child before, but he's not quite presentable enough to be among the Qiong Ding disciples, despite the wonderfully elaborate clothes he's wearing. He enjoys food like he's tasting decent cooking for the first time, so he must not have been here long. Shen Qingqiu remembers being much the same when he first got to eat regularly, but hiding it much better, thank you very much.

Shen Qingqiu decides that he's going to keep an eye on his shixiong's charge until the man wakes up, because it's obvious that the kid can't be allowed to wander the peaks unsupervised. This decision has obviously nothing to do with Xiao-Su's instant hatred towards the little beast. Nope. Nothing at all.

Xuan Su eventually does manage to tell Shen Qingqiu that Qi-ge came back for him. Yue Qingyuan wakes up and confirms that yes, that bratty rascal is the great and powerful Xuan Su. They eventually learn about Binghe's demonic heritage and go investigating how the hell that has happened. But not before a few weeks of shenanigans and Luo Binghe accidentally winning Xuan Su (and by proxy Shen Qingqiu, much to the man's annoyance) over by the wonders of his godly cooking skills.
