Are you a traveler? If you didn't follow the passage, then... you may have gotten here through [map 250000000]. Have you noticed something strange lately?
#b Something strange?

Something strange, as in a supposedly-stoice Jar walking around, attcking humans. [map 251000000] is a heaven for Jar to store medicines there, but one day, Jar started really walking and causing havoc.
#b What... there's a ghost in Jar?

No, it' s not a ghost. It's just some random big creature inside Jar, controlling its every move. I have no idea what that is, but the residents here are really going through trouble for this. If you can, can you please help us fight Jar?

Thank you so much. I want you to eliminate as much Jar as possible... around 400. Since no one knows exactly what it is, everyone's still scared to walk around the streets. Be careful. Good luck.

It's not a ghost, so you won't have to worry about that.

You managed to defeat all 400 Jars on time. Thank you so much! We can always get an empty Jar, but no one should ever be hurt by it. Thank you again.

I don't think you have defeated 400 Jars, yet...
