I still think the belief the ducal scions as having equivalent talent to Ling Qi is wrong. And or that
@yrsillar got the balance wrong on pre-14 cultivation.
To be frank Meizhen has almost certainly been spending a lot of this year doing closed door cultivation as she doesn't suffer from social action he'll like we do. Combined with having a general drug regime that's generally as good or better than ours staying ahead should be possible even with significantly lower talent. Imagine the equivalent of high sun type pills, which Jiao could afford to give out to about 30 disciples. every week from the start.
The pre-cultivation thing does seem to run squarely into 'why bother' territory though. Given how hardly Meizhen apparently worked pre-sect her return in effort investment was staggering low. To the point where I can barely see the worth for the clan in terms of drug costs. Especially given the expected lifespans of these cultivators.
Maybe literally all cultivation before 13 is done sans drugs and stones? It'd make little sense but it's the only way I can remotely see it being worth it.
I mean it was one thing when it was the Ling Qing and Ji Rong's steadily catching up. They're freaks of nature with both absurd work ethics and good or incredible luck. Heck even Xiulan catching up is ok since she basically did a 50% death roll for power. But Han Joan,, who was a massive slacker for ages and got stuck in breakthrough hell for months isn't far behind and he started much later in year terms.
Which again comes back to the fact that everyone is going to live hundreds of years and 6 months shouldn't be that important.
Maybe I'm just really really underestimating how much money these clans have.
