Did you get to explore Memory Lane 2? You probably weren't able to go further than that. That's because the permission I gave you was only up to Memory Lane 2. You only proved you had enough strength to go to Memory Lane 2, therefore you can't go beyond that.

If you want to go in further, you have to take another test. Is that what you want? Are you up for it?

Then go to Memory Lane 2 and defeat the Memory Monk Trainee. 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 reached your limit.

You've defeated 999 Memory Monk Trainee. That's amazing. I will grant you permission as promised.

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

Go on. You should be able to go up till Memory Lane 3. 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.
