One Piece: Unreal Adventure

"Okay, now beat those crabs. I'm feeling like eating some sea food today." Garp said as he picked his nose. And before the boy could say anything he kicked Luffy off the high ground. They were actually on a breaking point of a cliff, that was around five to six stories high. But for the old navy hearo, it was considered normal to throw their grandkids from that height.

The boy was caught off guard but managed to land on his feet. Landing on his feet like jelly that is.

"What the…" only then did he notice the surrounding, it was filled with yellow stony rocks, and what appeared to be a large sea area. And a destroyed forest, as if someone was eating the trees or something.

"Wait, there aren't yellow rocks in Dawn Island!?" Luffy said, looking up where Garp was, the old man was sitting at the top of the cliff picking his nose. Luffy looked at him, "We aren't on Dawn Island, are we?"

"Bahahaha, so you figured it out." Garp said, leaning down, "This is another small island, which isn't that far from home. Beat those crabs, or I won't take you back with me…" he grinned, and that made the boy shuddered, he wasn't lying on that part.

Luffy gulped. And wanted to ask what crabs, but stopped himself, as the yellow rocks started shacking and large tree-like arms sprouted from the ground. And now in front of him was a sea of large sea crabs. Each one of them was big enough to flip a truck with their claws, and were massive in size, almost one store in height. And there seemed to be, at least a hundred of them.

Garp then had a twisted smile on his face, "…Try finishing it before dinner. I wouldn't want to leave my grandchild behind like that…" he said as he yawned.

"At least try to sound genuine." the boy grumbled.

Luffy knew he was facing danger, even with the strength he gained in those short amounts of time, he couldn't beat all of them. And he had to do it even without using 'Soru'. And he was sure finger pistol won't do shit with how thick their shell was. Oh, he was so fucked up.

"Gramps, I don't think I'm not strong enough…" Luffy said, honestly. All of them looked quite dangerous. He did fight large animals in dawn island, but it was always one or two at the same time. Not like this massive group.

Garp looked at him with a frown. "You know you awfully complain a lot. If you aren't strong, then be strong."

What kind of freaking logic was that. Oh yeah, the One Piece kind.

Luffy gritted his teeth, taking deep breaths to calm himself down. He was going to make a name for himself in this world, and he wasn't going to back down now. He unstrapped his naginata 'Horn's Edge' from his back, looking at the crabs.

"Old man," Luffy said, not looking at his grandfather, "I am going to beat all of them and get home… then you are going to teach me what I want." he said, no, demanded.

Garp grinned as he sat down. Opening up a bag of chips from nowhere and started eating them. "I will hold you to that… Bahahaha."

"But… I want you to teach me how to cut steel." Luffy said.

Garp stopped his laughing and blinked at Luffy. He was about to refuse and say that it was some secret technique that marines can do. It would kind of be a hassle to teach him that. Too much work. But Luffy was quick.

"Shanks had shown me that it was possible to cut steel." Luffy said, making the old man grumble, "And he wasn't a marine."

"That two-cent pirate and his toothpick. Like I would…"

"Oh! So does that mean, the Marines don't know how to do something that a 'two-cent pirate' can do?" Luffy mocked, readying himself as the crabs started their march toward him. He was playing on unknown ground here, but who gives a shit, he needed to get stronger. And he was going to take a shortcut if they were there. "And here I thought, my gramps wasn't some old fossil from Roger's time."

Learning to cut steal would not only help him with his naginata, it would also make things easier with Zoro. Teaching him that before the grand line would be a boon for the future. And like the shameless bastard he was he was going to learn it before he set out from Dawn Island.

What? He liked being overpowered and one shotting opponents.

That made a tick mark appeared on Garp's forehead, "Why you… Don't make me come down there and hit you, brat." He huffed, almost destroying the bag of chips he was enjoying, "But fine… You beat those yellow crabs, and I will teach you that. Heh, and I will show you what this old fossil can do." He grumbled.

Luffy felt a bit worried, about what method the old man would use to teach him. But he had more recent concerns.

One of the Yellow crabs came fast with its claws out and tried to grab onto Luffy. The boy jumped away from danger and mid-air he spun, "Gomu Gomu no War Axe." Stretching one of his leg and smashing it on top of the crab's face and it made the giant creature scritch a little, before he tried to smash away Luffy.

Luffy managed to land somehow, using his spear to block the smash that was coming from the giant crab. But it didn't make the boy fling away like expected, rather he stood his ground with his inhuman strength. Even though the ground almost buried him.

Luffy grinned, "So all my training wasn't for nothing." he said as he rolled to the side. Time to get serious.
