For how many minutes would someone with 95% aptitude cultivate in 1 session? (Until the primeval essence runs out.) Do some use the essence in small amounts and other use it rapidly in nurturing the aperture walls? If yes then what are the benifits and downsides?
1 hour? 2 hours?
I know fang yuan cultivates for like 24 hours nonstop in qingmao mountain arc, but i remember that bieng some method of his to compensate for his lack of aptitude.
