I am usually not into crossovers, but...
I am dying to see a Star Rail/Genshin absolute madcap hijinks crossover where it turns out Zhongli is actually just the aeon of Permanence who faked his own death and fucked off to Teyvat when he got tired of his first job, where he's been loafing (and re-retiring--because hey, if the fakeout death thing worked once, why not give it a go again??) for the last 6000+ years.
Only for Dan Heng and the Astral Express to roll up (look, the train can definitely fit through the big ass hole in the sky now) because there's some issue seriously affecting the Xianzhou's Vidyadhara and the Garden of Recollection says Teyvat's primordial dragons may have information that can help save the day.
Bonus points for:
Zhongli spending the first half of the fic like
desperately trying to dodge responsibility for his past actions.
2. Zhong-"How about we don't talk to the hydro dragon today"-li. (Dan Heng will get along great with Neuvillette though!)
3. ZhongChi (with scandalized Dan Heng in the background because there is no way his oldest ancestor is flirting with some 20-year-old ginger.)
4. Blade's there at least part of the time. Why? Because I want to see Zhongli put him on the ground and then be like "Oh dear, is this someone you know, Dan Heng? My apologies," and bodily pick Blade up and dust him off--only to then immediately grind Blade into the ground again after getting the actual story.
5. Dad!Li and Son!Heng feels. Does Zhongli know how to be a responsible parent? No. But that's okay, because Dan Heng also has no idea how to be a son. They'll get it worked out eventually. Probably.
6. Where in the name of Teyvat did the rest of the Express Crew go? *comedically large explosion in the distance* "Oh no. Those are my monkies. That is my circus!" - Dan Heng, probably
7. Epic Dan Heng + aeon!Zhongli team up to save the universe. (From who? I don't know man, invent a random big bad villain just so I can see this.)
