One Piece: Unreal Adventure-Chapter 88: Our captain doesn’t fear any challenge.

The Going Marry sailed through the water with great speed with the help of the sea king pulling. Nami had to only adjust the route a little bit... and it certainly cut down the travel time.

Two days had already passed it would take another day to get to Sakura Island. The crew was mostly training their ass off in the two days. And it certainly boosted their physical strength.

The growth was very noticeable and it wasn't just because of hard work. Even Luffy gained some strength. But only a tiny bit, but others improved very well. Their recovery speed was quite fast, that's why they could improve in a short time.

And it might be because of Sanji's cooking skills. While the members of the crew had yet to learn Seimi Keikan, Sanji's food could be easily absorbed into the body giving immediate effects.

Seimi Keikan is being able to control all parts of your body. One can even eat a tree log or dirt and extract calories from there if he uses the technique. Luffy had tried it once, eating no food for a month surviving off things that weren't considered food.

Huh... The things he did for the grind.

While his crewmates didn't master the technique to that extent —even Sparky wasn't able to do it, Johnny and Yosaku only knew the basics of it— they were able to get very nutritious food due to Sanji. Who knew having a good diet would be important?

It seemed that meat from sea kings was very dense in nutrition and the body wasn't able to fully absorb it. But with Sanji's cooking skills, they were able to do it.

So knowing this... Luffy made all of them work hard. But then again he wasn't like Garp or Bogard.

He was a man of the grind. But as a previous powerlifter and strength athlete, he knew that overtraining would bring bad results and bring hate towards hard work. So he placed the training sessions in a way where the crewmates were actually enjoying the hard work and gain results at the same time.

But it also made him jealous in a way... now there was no Garp to constantly fight against. He wasn't getting any stronger like he was used to.

He did get some strength after having the small clash with Hawkeye, but it wasn't that much. He was pretty much spoiled into fighting stronger guys, because of Garp. So he felt a bit depressed that he couldn't gain that much strength.

Even with Sparky's help gaining even a bit of power or speed was getting difficult. That's why he was going to take drastic measures.

The ship stopped in the middle of the ocean, and all the people on and off the ship were looking at Luffy. Even the sea king Momoo was looking at what Luffy was doing.

"Um... captain, are you sure about this?" Coby asked a bit scared of what Luffy was trying to do. The captain in question was tying a thick roped around his arms and waist.

"Don't even bother... I tried to talk him out of it for an hour now." Nami grumbled. "If something happens... I will be the gal, that told you so." She said sticking her tongue out.

Luffy shook his head, "You wouldn't understand the grind, woman. Now go on and make me a sandwich."

Nami snorted, ignoring the verbal retort. But she was honestly a bit worried herself.

"What you are doing is, certainly stupid captain," Kuina said, crossing her arms. "But then again I understand where your coming from."

Zoro also nodded. "Just don't get us lost in the sea, Luffy." He chuckled a bit, but stopped when everybody gave him a deadpan look. "What?"

"Of course something idiotic, Moosehead." Sanji snorted, which brought a tick on the swordsman's forehead.

"You want to go round, shitty-cook?"

"Heh, I'm gonna kick your ass like the last time." Sanji rolled up his sleeves sparks flying between them. "But it's on shitty-swordsman."

*bam

Both Sanji and Zoro were on the floor because of a certain navigator who didn't like the useless commotion.

"Hey! Sanji might be needed if the line is snatched, ya know." Luffy mused. In two days, Sanji was already able to get the basic concept of Soru down and even was able to use it in water... of course he named it Blue Walk.

But he was nowhere near mastering Geppo, or his version of it. But the fact that he learned it meant that he would eventually be able to master it.

He was also trying to learn the tempest kick. But the technique was still far from him... as the concept of air slash was a bit vague for non-weapon user like him. It was basically an unarmed version of air slash...

"But then again, Hatchi will save me if that happens..." Luffy mused.

The Fishman in question was this time on the ship and looking at Luffy weirdly. "Of course, I will... but are you sure you want to do this..." he said. Hatchi might not like Luffy that much, but he didn't have any animosity towards him. So he wouldn't stand by if he was in danger... how else was he going to prove that all the Fishman weren't all like Arlong. "Momoo can pull the ship just fine... I haven't seen any devil fruit users even able to move their body in water... let alone swim and pull a whole ass ship tied to his back."

The sea king in question was now untied and curiously looking at what the crew was doing. Sparky seemed to bond well with the creature as he sat on top of Momoo's head.

Luffy had to agree himself that it was certainly stupid. Pulling a full ship in water as devil fruit user wasn't something you should do.

But... Luffy was going to do it anyway. And besides he trusted his crewmates.

The years of training with sea stone and water training made him gain a bit of sea immunity to speak. Don't ask how, it just worked. Luffy didn't know if that was possible, but it seemd that overexposure to the sea made it such.

This world was definitely different from the original One Piece world. As he knew that even Jack who was Fishman couldn't swim in the ocean.

And here was Luffy... who was able to swim in the sea for a whole minute before the drawback from the energy-sapping would be too much and he needed would need a break. Luffy at the time did in a small lake, but he never tried it in the open sea... but now he could.

After starting his journey, Luffy hadn't tried breaking that record.

Sure he had a sea prism stone bracelet, that he wore while training with his crewmates. But now, it just sapped away his devil fruit power, not his strength. And it was still a good way to gain muscle mass without blocking in size.

"Swimming is a good exercise for speed and strength anyway, and add the drawback of the devil fruit into the mix. It's a total challenge." Luffy grinned.

"That's so Manly Captain!" Johnny cried while holding Yosaku.

"Our captain doesn't fear any challenge." Yosaku said... both former bounty hunters aweing at Luffy. As the sea was basically suicide for a devil fruit user. And Luffy was taking it as a challenge to do the impossible.

"Captain... I think you should still think about it." Coby muttered. After eating his fruit, he tried to take a bath once, but he almost drowned himslef at the time. So he was a bit worried about Luffy.

Luffy on the other hand was thrilled at the aspect of what he was about to do. Adrenalin was already pumping in his veins, he just couldn't wait.

"Shishsishi..." Luffy laughed, now that the rope was tied up, he jumped to the head of the Going Marry. "This is going to be fun. And don't you underestimate me, sea... In a few years, I'm going to be the strongest thing alive in this world! Whoohooo!"

*Splash

The rest of the crewmates hurried to the front of the ship just as their captain jumped into the water.

They were a bit worried when they didn't see Luffy resurface for a few seconds. Zoro and Sanji already got their sandals and shoes off along with their shirts, in case they needed to jump in save Luffy.

Gin on the other hand had absolute confidence in his captain as he focused on the water below. But Luffy was yet to show...
