The One Who Walks Through the Road to Oblivion 4

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

Then go to Road to Oblivion 4 and defeat Chief Oblivion Guardians. If you defeat 333 of them, I will grant you permission to go further.

That's too hard for you? That's too bad then. I guess that's just your limit.

Astounding! As promised, you have my permission to move further.

k.

Go on. You should be able to go up till Road to Oblivion 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.

You haven't defeated 333 Chief Oblivion Guardians yet. I don't think you are strong enough to walk against the flow of the past yet.
