hmm au where second prince lan wangji gets cursed and his son lan sizhui decides to venture out to find and kill the caster so he can save his dad. the caster, jin guangyao says with pity, of course has to be the dreaded yiling patriarch

and so anyway the juniors all go out on a quest and mid-way they find this lunatic named mo xuanyu who's far too invested in lan wangji's business, but hey at least he's helping them clear the trials to get to the yiling laozu's lair!

idk and idc about everything in the middle. just want this scene ft the yiling laozu, smiling, blood spilling from his mouth and sizhui, his sword lodged in his stomach and eyes wide with horror as all the memories of where he came from come rushing back to him all at once
