Comments of chapter undefined of Against Heaven's Will

i have forgotten so many things.. can someone explain some of my doubts please? first, why xuefeng's wives op and immediately comprehend everything? just because they dual cultivate with him or other reasons? second, whatever talent xuefeng and his wives have due to their personal and fate abilities, is it so great that it rivals these constellations? because Pio stated earlier that even the fate king is nothing compared to them and many of them heavily rely on fate abilities.. third, that mysterious realm from where the elemental bracelet came from, is it part of / related to fate kingdom or this universe when our mc is OR it is on the same level as these constellations? forth, was Ming the Queen who ruled the fate kingdom or was she just the queen in name, meaning just the wife of the king with no authority as she didn't even know about these constellations ..
