The Map is in One Piece

Oh, these pieces form a map that shows where the 上古魔书 is hidden! Hmm, I must put them back together to read it, though...

Now, you must stay silent. I have to perform very, very special magic ritual to put them together... *Murmur* Hyaaah!

We can read this map only if we put all the pieces together. Bits of maps are useless.

Ha! My unbliteration spell worked! Now that we have one complete map, let us study it... Hmm, yes, yes... Interesting. I can't read this at all.

I'm studying all 4 of the 古地图碎片 that you got me. It doesn't matter if they aren't put together into a single piece! 伊吉上等兵 of Alpha platoon must have found 记忆之粉 while investigating something around the Orbis Tower. Can you get the item for me, please? Thank you!

I don't know what you're going to do with it, but it's a pretty important item so I suggest you handle it with care. If you screw it up and throw it away in an accident, it'll vanish without a trace, so be really careful with it. Well then, bye.
