A week later...
Sabaody Archipelago, 71st Island.
In the living room of a large villa, Sephiroth wore a white suit, sitting back in an armchair with one leg crossed over the other.
Beside him, Gild Tesoro and Stella sat on the long sofa.
After just one week, Jim's physique had gone from a skinny bamboo pole to a round ball, his rate of weight gain absurdly fast.
Jim now stood before the three of them, holding a heavy rocket launcher over five feet long. He patiently introduced it to them:
"After adding the special alloy I created with my ability, this Javelin Rocket Launcher not only has an effective range of one thousand meters, but if loaded with specially made armor-piercing shells, it can instantly blow even a medium-sized sailing ship to pieces.
"Although it hasn't reached the effective range of 2,500 meters you requested, Boss, so its specifications are somewhat lacking...
"For now, though, it's the most powerful weapon in our arms factory."
"Oh? Then this will do..."
Sephiroth smiled, leaned forward slightly, and opened the case on the table, revealing two Devil Fruits inside. One was the Dog-Dog Fruit, Wolf Form, while the other was the Door-Door Fruit.
He picked up the gray Dog-Dog Fruit, Wolf Form and handed it to Jim.
"Try fusing this fruit with the rocket launcher, just like you made the alloy...
"But I suggest you swallow it whole. Don't chew it..."
Gulp!
Jim immediately shuddered, a bead of cold sweat rolling down his forehead. He was not some ignorant fool who knew nothing about Devil Fruits.
He knew that if someone ate two Devil Fruits at once, the different powers would clash within their body, causing them to explode...
Jim glanced at Sephiroth, who sat in the armchair, his heart filled with unease.
