If you want to go further, you'll need to take a harder test... But you knew that already, right? So what do you want? Do you want the new test?

Then go to [map 270030300] and defeat the Oblivion Guardian. If you defeat 999 of them, I will grant you permission to go beyond that.

That's too hard for you? That's too bad then. I guess you can't go further.

You've defeated 999 Oblivion Guardian. That's amazing. I will grant you permission to move.

Go on. You should be able to go up till [map 270030400]. As you can guess, you can't go beyond that. If you want to go further... you'll have to take a new test.

As the representative of Rhinne, the Goddess of Time, I grant you permission to look back at your 4th oblivion.

You haven't defeated 999 Oblivion Guardian yet. I don't think you are strong enough to walk against the flow of the past yet.
