It was possible that their intelligence was much higher than before.
And at that moment, because they had set up the Spirit-Absorbing Spell Formation, their spiritual power had severely depleted.
Plus, as they had sacrificed themselves to possess the descendants of the sect, their bodies were unable to recover spiritual power on their own at that moment.
