For instance, in the Blood Skull sect, there should be only five people with a perfect foundation. Those people should be Pink Ivy, Void Claw, Patriarch Thunder Drake, Patriarch Evergreen, and Patriarch Sword Flash.
Stella was the one who told him this. She was also the one who told him that Storm Hawk didn't get a perfect foundation.
It goes without saying that it is the people with perfect foundations that sects prioritize when sponsoring golden core cultivators to advance to the fifth mortal coil.
So now that he has advanced and there are three people at the fourth mortal coil with a perfect foundation, the slots for the fifth mortal coil have been filled up.
Unless one of the three golden core cultivators with perfect foundations dies, the rest will stand no chance of getting the support of the sect in advancing to the fifth mortal coil.
