@Thekillman: This technique was specifically made to counter Obito's MS ability. She had been monitoring him for years. It wasn't stated whether or not she begun the preparation for this technique during that time, but she even confirmed herself that she had to amass 600 billion paper bombs to kill him. That's not too hard to believe. She is an Akatsuki member, after all.

EDIT: What are you basing your calculations off, btw? I don't know if the time-frame for producing that much paper can be totalled.

RE-EDIT: Good point. I'm still not sure, though. She could've easily produced a few million every odd hour. That mightn't be mathematically correct, or logical, for that matter, but how far can logic go in an anime? We don't know. But what we do know is that she conjured 600 billion paper bombs.
