Become a Saint? And I Still Have to Complete the Slay the Gods Tutorial Quest?

The Heavenly Dao thinks I'm too powerful and doesn't want me messing around in the Primordial World, so I sealed my cultivation and came to the world of Slay the Gods. Wait, I've already become a Saint, so why do I still have to do beginner quests? Can't these quests be a little less ridiculous, damn it? What? I have to make a heartfelt confession to a trash can?
