If you want to go in further, you'll need to take a harder test... Makes sense, right? So what do you want to do? Do you want a new test?

Then go to [map 270020200] and defeat the Qualm Monk Trainee. If you defeat 300 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've reached your limit?.

You've defeated 300 Qualm Monk Trainee. That's amazing! I will grant you the permission as promised.

As the representative of Rhinne, the Goddess of Time, I grant you permission to look back at your 3rd regret.

Go on. You should be able to go up till [map 270020300]. 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.

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