If you want to go in further, you'll need to take a harder test... Makes perfect sense, no? So what do you want? Do you want the new test?

Then go to Road of Regrets 4 and defeat the Chief Qualm 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 that's just your limit.

You've defeated 999 Chief Qualm Guardian. That's amazing. I will grant you the permission as promised.

Go on. You should be able to go up till Road of Regrets 5. As you may have guessed, 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 5th regret.
