Trying to play Amazing Cultivation Simulator.
Restarted once and maybe again because of how slow I feel I'm progressing. Last attempt, I missed the peak time of the year for my starting inner to breakthrough to Golden Core, though a total lack of viable materials for a decent cultivation room didn't help(or poor Law compatibility). Current attempt, it took me 15 days for my starting inner to actually become an inner disciple - I avoid using the starting Forming Pill for two reasons: first, it's going to be a while before you can replace it and it has other benefits besides instantly building an outer's foundation, and second, because there's simply so much work to be done initially building up the place that I can't spare the labor. Luckily my second attempt I picked up a wolfgirl early on, which helps(because she runs fast, and over 200 days before her tribulation).
Both attempts I my starting inner was setup for a the Sunflower Refining Law and a massive Social skill. This can be done by re-rolling the character stats until Social is at least 50, and taking the Hedonist perk, which increases both Social skill and Charisma(which Social is based off of) and gives them 100-quality clothes. You need a massive Social skill to do the main story stuff. I'm finding Sunflower is a slow Law to start up since you need to make a cultivation room out of fire, which has a lot of problems(like fire).
I've heard of a run where someone got a tier-1 Golden Core with True Sun Refining Law by day 5, but I haven't seen how they did that. Nor am I going to attempt that. My concern with slow progression is due to the fact that I've lost runs because I didn't get strong enough quickly enough to defeat the demon beast on the map - which is stronger than the average beastie, gets stronger over time, eventually wakes up, and finally attacks your base. There's also some time-limited stuff, primarily with the main story, and generally has little to do with how strong your sect is as far as I know.
