So let me get this straight. 1million years of idling got him 1.2million low grade spirit stones. you have to idle for 800 years just to pay the third grade sect your annual pay. Something dont add up. (Yes i know he got other high grade resources, but the author really didnt think this one through)
so can the cultivation be passed on to other people? if so, he can raise his own level to a believable place then level up the remaining sect disciples so they can play a bigger role in the development. I think there was only a few people left right? also, did it say how old he is? I missed it if so. as a sect leader he'd probably be middle aged or older right? unless he only got the position after everything declined...
