Ning Qi frowned slightly; this was going to be difficult.
The Saint Ancestor again spoke, "What exactly was that key you took out at the time?"
The Saint Ancestor probably could never forget what happened before the Immortal Door.
That golden key could reverse-plunder the energy behind the Immortal Door, causing even the pavilion in the Upper Realm to collapse.
Ning Qi took it directly from the Storage Space to let the two have a look.
"This item is a treasure I obtained while searching the Profound Truth Realm in the Mountain and Sea Realm; it can suppress Infinite Evil Qi. I never would have thought it seems related to the Upper Realm."
The key floated in the void, seemingly shining with golden radiance automatically around itself because Ning Qi let it out.
It was no longer like before, a divine object with mysterious restraint, clearly possessing a more dynamic feeling.
