One Piece: Starting as a Marine Lieutenant, I Slack Off and Get Stronger

Backstage area of ​​the main venue of the World Expo.

A tall, crimson-red man looked at the image transmitted by the video Den Den Mushi and revealed a wicked smile.

"The new Pirate King, huh? I'd like to see what makes you think you can stand on equal footing with Roger!"

"Barrett, are we going now? Isn't it too early?"

Barrett glanced at his partner indifferently and said coldly, "Just do your own thing."

With that, Barrett turned and left.

the other side.

"Sabo, what should we do? Are we just going to wait for that guy to show up?"

Sabo nodded slightly: "That's right. Only when he appears can we join forces with Guild Master Sakazuki to issue an evacuation mission. Otherwise, these adventurers won't listen to us."

"Kera, you'd better stay put, or we won't have time to deal with you when the fighting starts!" Betty, the former commander of the Eastern Army, joked.

Kella pursed her lips and didn't say anything more, because in terms of combat strength, she was just a junior among juniors, and it would be good enough if she didn't drag the team down.

The scene returns to the scene where Luffy, with the help of his crew, escapes from Bonney and Law's clutches, while Aramaki is held back by Shanks. This allows him to be the first to reach the artificial sky island. However, to his surprise, someone is faster than him.

Looking at the mountain-sized red man in front of him, Luffy was puzzled. He didn't seem to have seen him just now.

Wearing a black military uniform, Barrett gave a wicked smile, revealing a set of big white teeth, but he did not answer Luffy's question. He simply leaned forward slightly, his muscles tense.

Luffy's pupils contracted, and he quickly assumed a fighting stance, but the next second, a sonic boom rang out, a sharp pain shot through his abdomen, and he was sent flying.

"Is this the strength of the Pirate King? Heh, utterly pathetic..."

Luffy pushed aside the rubble, got up from the ground, and looked at Bullet with apprehension.

Such immense power! This guy is definitely a master of physical combat, but how come I've never heard of him before? Do I have to defeat him to become the strongest adventurer?

Wait, he just mentioned One Piece or something, could it be...?

"who are you?"

Barrett cracked his neck, making a series of popping sounds. "Looks like I've been gone too long; the sea has forgotten my name... But you don't need to know my name, because you're about to die!"

boom!

Barrett charged at Luffy like a cannonball, unleashing a storm of attacks on him using the killing techniques he had honed over the years.

"What's going on? Why are they fighting? Are there other people up there?" Zoro asked, looking at Law with a puzzled expression as he sensed the commotion above.

"I don't know. Don't look at me. If you want to know who it is, why don't you go up and take a look?"

Zoro nodded. Since Luffy hadn't won yet, there was no need to keep the others here.

As a result, more and more people landed on the artificial floating island.

"That was awesome! Again!!! Rubber King Ape Gun!!!"

Barrett was not afraid at all. He dodged Luffy's punch by turning to the side, then reached out and grabbed Luffy's arm. When Luffy bounced back, he punched him.

"Luffy!!!"

Zoro, Sanji, and the others rushed forward to check on Luffy's condition. The moment Law saw Bullet, his pupils shrank to a single point.

He had heard about this man's story while he was in Impel Down.

As more and more people approached, Barrett was not afraid at all; instead, he became even more excited.

After escaping Impel Down, he lay low for three years, learning about the world and figuring out how to surpass Roger and become the strongest in the world!

Now, his physical condition has recovered to its peak, and he has even become stronger.

Moreover, he also figured out how to prove that he had surpassed Roger and become the strongest in the world.

That is, to kill all the strong with an unparalleled strength!

"Luffy, are you alright? Who is that guy?"

"I can't make it?"

At this moment, Shanks walked to Luffy's side and looked at Bullet with apprehension.

"The successor to the demon, Douglas Barrett, was once also a member of Roger's crew."

Chapter 390 Bonus Chapter: Adventurers' Expo 4

At this moment, Barrett also noticed Shanks behind Luffy.

"Shanks, I remember you. Back when I was on Roger's ship, you were just an apprentice. I never imagined that after Roger's death, you would become the Emperor of the Sea. How interesting!"

Barrett laughed heartily, the sight of so many powerful figures had already set his blood on fire.

"Come on! Let's have a good fight!!!"

Boom~

Barrett unleashed a demonic Conqueror's Haki that instantly swept across the entire artificial sky island, creating a suffocating sense of oppression that gripped everyone's hearts.

Luffy slowly stood up from the ground, looked up at Bullet and said, "Since you want to fight, then let's have some fun!"

Dongdong~dongdong~

The Drum of Liberation emanated from Luffy's body, and with the vibration, Luffy directly entered Nikka form, floating in mid-air and releasing Conqueror's Haki to clash with Bullet.

Looking at the completely different Luffy, Barrett's expression changed slightly. A Mythical Zoan?

"Haha, come on then!"

bang~

The real battle has officially begun.

Meanwhile, Carl was cooperating with Sabo to disperse the onlookers, sending them home to their own families, so that the things on them wouldn't become nourishment for Barrett to become stronger.

"Phew~ It's all thanks to you, General Karl, otherwise, these people might not have been willing to leave."

Karl chuckled and patted Sabo on the shoulder, channeling holy light into Sabo's body: "Haha, reputation can be quite useful sometimes. You still have a long way to go compared to Dragon."

"By the way, most of the people have been evacuated now. I see there's a big fight going on up there. Do you want to go up and join in?"

Sabo looked up at the distant sky island, flames suddenly erupting from his body as he grinned and said, "Of course, my brother is still up there!"

"You brothers have a really good relationship! Let's go!"

With a whoosh, Karl appeared above the sky island in the next second.

Sabo was slightly taken aback, and exclaimed, "Such speed! No wonder he is the strongest man in the world."

Although Karl has never admitted it, in the eyes of the outside world, Karl truly deserves this title. Even the Navy has intentionally or unintentionally promoted Karl as the strongest Navy in history. After all, Karl is now the Navy's golden brand.

When Karl arrived, Barrett was taking turns fighting Luffy, Shanks, Zoro, Sanji, and others. Judging from Barrett's condition, he was not at a disadvantage at all.

Only Luffy can gain an advantage through his abilities; even Shanks, the others are helpless against Bullet for the time being.

Watching Barrett maneuver with such ease, Karl couldn't help but marvel that this guy was practically born for battle.

Shanks' swordsmanship and Haki are strong, but Barrett is no less so. However, don't forget that Barrett's physique far surpasses Shanks'.

"Luffy, I'm here to help you!! Flame Dragon King!"

Upon arriving, Sabo immediately launched an attack on Barrett. Barrett, who was fighting Luffy, didn't even look up, grabbed Sabo's hand, ignored the scorching flames on Sabo's body, and then threw him towards Luffy.

Duang~ Luckily Luffy inflated in time, otherwise he would have flown out with Sabo.

"Sabo, are you alright? This guy is very strong, we must not let our guard down!"

Sabo scratched his head: "General Karl just blessed me with Holy Light, I thought I could..."

“Karl?” Barrett’s pupils contracted, and his heart began to pound.

He was initially quite disappointed not to see the navy at the World Expo opening ceremony, because the navy's absence meant he had lost the opportunity to face the world's strongest opponent. But now...

Barrett instantly activated his Observation Haki, then looked up sharply and spotted Karl watching the battle from the air.

"Karl!!! Hahahaha, you've come at the perfect time! Let me witness the world's strongest power!!!"

bang~

Barrett ignored everyone else and charged at Karl with his iron fist raised.

Karl narrowed his eyes slightly, staring at Barrett's figure. Just as Barrett was about to hit him, Barrett's figure vanished instantly.

Just as Barrett was searching for Karl, the sound of something cutting through the air came from above Barrett's head.

Barrett looked up in disbelief and saw a huge lightsaber descending from the sky, aimed directly at the top of his head.

Barrett hurriedly raised his hands to block the blade, but his entire body was pulled towards the ground by the lightsaber.

Boom~

Spiderweb-like cracks appeared on the ground, and Barrett was in the center of the cracks, a giant sword of light stuck in his chest, blood gushing out.

"burst!"

bang~

The giant sword of light released astonishing energy and exploded with a deafening roar, causing the ground to tremble once more.

Those present couldn't help but swallow hard. Barrett, could he still survive?
