Franky hummed while he worked. He was feeling rather smug at the moment.
Those CP9 goons were so easy to fool. Honestly, he was a shipwright, an inventor, an engineer... give him a blueprint or even an idea and he will have something built in no time at all. Did they really think that him burning those blueprints for Pluton meant that the plans were forever lost?
By the way they reacted, he was pretty sure they did.
No, he had long ago made a fake, incomplete copy of them and hidden the originals somewhere nobody would ever think to look, even if they had been able to. He'd also memorized them, but they didn't need to know that.
In the years since he first 're-built' himself following his (rather stupid) attempt to stop the sea-train, he'd made some modifications to his mechanical structure. What nobody knew was that his left leg was hollow, and that it made a very good place for hiding or storing important documents.
(Of course, this also meant that he had to be careful in a fight, since there was only so much pressure and damage a hollow bit of metal could take before bending, no matter how strong the material used.)
So, when CP9 came looking for the plans, he'd pulled the fakes out, hid them in his chest compartment, and then pulled them out on the balcony at Enies Lobby, facing the Strawhats lined up on the roof across the chasm, and burned them, making CP9 think that Pluton was lost to them forever.
He hadn't even told his crew yet that he still had those blueprints. He would eventually, he knew he would. First, though, he was going to complete the modifications to the Sunny's main cannon... when he was done, the Sunny would be the most powerful weapon in history, known or lost.
He would make sure of it.
