Theres one other thing that might pose difficulty for her.
An explicit part of the Silver breakthrough is healing all cumulative injuries that the body has experienced and returning it to a pristine(excepting inpurity) state.
For Ling Qi that was a poorly healed broken leg and miscellaneous bumps and bruises.
For her Mom that'll be quite a bit more.
Thats actually why I considered Green to be fairly attainable given resources and time. Qingge's main issues stem from her age being twice the 'normal' age for the bracket, and the cumulative damage to her body. Breaking through to Yellow(which is mathematically inevitable) would solve both issues, her cumulative mortal damages would be gone and for her age...remember the Peak Yellow scout we were on mission with?
He's looking to breakthrough in his second century, with much more limited resources and does not seem to be in any doubt about succeeding eventually, so being 30-50 years old by then wouldn't be as major an obstacle as being 30 years old is for a Red.
I think that we're all both vastly underestimating how long Red and Yellow are going to take and overestimating how difficult it will be to reach Green (assuming no crippling injuries).
Now my 'calculations' are based on all of 1 data point on Ling Qingge's side and how fast we awakened comparatively, and they're already at least slightly off if she didn't reach Gold body last turn, but until we actually get that second data point this is the best I can guess.
IIRC we're supposed to spend 2 years in the inner sect, I expect her to be just barely reaching Mid Red soul and Mid Gold body around then.
After that we've got 8 years of service in CRX's fief. I expect her to breakthrough to the second realm about 3 years into that. By the end of our service in CRX's fief she should be reaching Late Yellow/Late Silver
Biyu is 4 now, so 3-4 years after that she'll be going to the Sect, assuming nothing province shaking happens before then. By then Qingge might be reaching Peak Yellow if she follows a cultivation pattern similar to ours, which is a big if.
And that would lead to a third realm breakthrough about 15 years after starting her cultivation. Now all of this assumes that she follows a path longer but roughly proportionate to ours and that breakthroughs just take a whole lot more time and pain but don't go bad and cripple her, so take this with a fistful of salt.
About the only thing I can say with confidence is that I absolutely do not expect Qingge to breakthrough to Yellow before we leave the sect based on her progress so far.
Keeping in mind that Qingge's progress actually points to Talent on par with Ling Qi in her youth. She's working through a big age/injury debuff, but said debuff falls off as she cultivates.
And crucially, the higher she cultivates the more things wealth can do for her. Reds have very limited arrays of drugs they can use, but they're there and we can basically put her on max drugs without anything we'd notice as more than a rounding error from our Green budget.
She makes Yellow and we'd actually need to start making decisions about how much wealth to sink into her, seeing as we probably can't afford max Sable Light Pills and their peers for her without actually doing noticable damage to our own cultivating budget.
For the matter, by Yellow Suyin's impurity remover project might actually be useful...
Zhengui can go be the harem protagonist.
I'm still unsure if i want any romance for Ling Qi.
Depends on how the story goes i guess.
Zhengui can handle it. He's very durable.
Though I don't think he'd notice the fuss at all, since last I recall Xuanwu have similar interest levels to giant pandas.
Maybe the Domain gets its version of hit points?
I believe at that point the domain hp is basically a seperate set of our own hp no?
