Chapter 1

"Logan, this is the fortieth time you've been beaten by your big brother today. If you keep this up, you'll die."

Xialipu said to Logan.

"Don't worry, I won't die. No matter who dies, I won't. Damn Kappu, let's continue."

"Damn Logan, I told you to call me big brother. Here comes my righteous fist."

"Bang..."

Yeah, I'm flying again. The sky is so blue, I really want to sleep.

Indeed, Logan had come to the world of One Piece. Logan was originally a shut-in on Earth, watching anime and TV at home when he wasn't working.

That day was a beautiful, sunny day. Logan had just received the Naruto card set he bought online, and One Piece was playing on his computer. While Logan was opening the package, he accidentally knocked over a cup of water on the table. While he was busy wiping the keyboard, he got electrocuted and saw the screen getting closer and closer. Everything went black, and when he opened his eyes again, he found himself in the world of One Piece, with the Naruto system, as the younger brother of the Marine hero, Monkey D. Garp. Logan had changed the world of One Piece, what an honor.

At this time, Garp was still quite young, about twenty years old. Logan was only ten. Logan wasn't clear about the timeline of Garp's younger days. This was a crazy era, and without strength, it was hard to survive, so he had to get stronger.

Fortunately, Logan had the Naruto system, which could cheat, but this broken system was also a pit. Either you had to pay money or risk your life, and Logan couldn't afford either.

Well, at least he had a strong big brother. While others relied on their fathers, Logan relied on his brother. He had to build a solid foundation first.

In short, this Naruto system was amazing. You could buy bloodline limits, sage modes, jutsu, and artifacts, but the prerequisite was having money. It was inhumane. Now, even transmigration was a world for the rich, leaving Logan and his fellow transmigrants in a difficult position.

You could buy reputation in the system and use it to buy what you wanted, or you could gain reputation by defeating opponents. The more famous and evil the opponent, the more reputation you would get. Checking the system, the highest reputation was for killing a Celestial Dragon, and seeing the string of zeros as a reward, Logan's eyes were red with envy. It was a pity that he didn't bring a nuclear bomb when he transmigrated. Otherwise, he could have flattened Mariejoa and reached the peak of his life, hahaha.

Looking at the Rinnegan, the Rinnegan, the Eternal Mangekyou Sharingan, the Sage Mode of Hashirama Senju, the Wood Style, and various jutsu, Logan's mouth watered. But looking at the corresponding reputation, he cried.

However, sparring with strong people also earned some reputation, so Logan took advantage of his big brother. Since Garp wouldn't kill him, he fought him to the death when he was on leave. Watching his reputation slowly rise, he felt it was worth the beatings.

"Kappu, I'm back. Haven't you eaten yet?"

After half a month of beatings, Logan didn't know how much his strength had increased, but he was definitely more resilient. He could grind down opponents of the same level.

"Damn Logan, taste my righteous fist."

"Bang, bang, bang, bang, bang..."

A beautiful symphony played again.

"Hey, Logan, you never liked exercising when you were young. Why are you so crazy now?"

Garp asked Logan, picking his nose.

"Kappu, in this world, can you survive without getting stronger? A major chaos is coming soon."

"Huh? What are you talking about?"

"Idiot, if you didn't hear, it's fine. Hey, Kappu, have you learned Haki yet?"

"Of course, I learned it from my instructor when I joined the Marines. Logan, why don't you join the Marines? That way, we can catch pirates together."

"Marines? Maybe, but not now. I'm too weak. I'd be killed by pirates before I could catch them."

"Don't worry, I won't let you die."

"You? Forget it. I'm afraid I'll die from your fists before I die from pirates."

"Damn brat, how can you talk to your big brother like that? Here comes my righteous fist."

"Bang."

Oh, the sky is so blue.

Hmm, if I calculate the time, Dragon should be born soon. I should ask about this.

"Kappu, have you found a wife for me yet?"

"Wife? What wife?"

Hmm? You don't have a wife yet? Garp is twenty years old, and according to the data, Dragon was born when Garp was twenty-one, in the year 1463. It's now 1462. Could my appearance have changed this? No, I need to find a way. If my nephew is gone, my One Piece grandson is also gone. Logan fantasized.

"Kappu, you should find a wife soon. Being a Marine is dangerous. If you die, you'll have no descendants!"

"Damn brat, what are you talking about! You deserve a beating, here comes my righteous fist."

Hmm? His face is red? There's something fishy. Tsk, tsk, so Garp isn't as dense as I thought. Since that's the case, Logan decided not to interfere.

Time passed as Logan kept getting beaten, and after a month and a half, he finally accumulated enough reputation to activate the system. He eagerly activated it.

Summoning the system interface, he chose to activate the system.

"Ding, system activation in progress, please wait."

"Countdown: 3, 2, 1, 0. Congratulations, host, system activation successful."

"Hello, host. This system is the Naruto system. You need to earn reputation to exchange for what you need. Since you successfully activated the system, the system will give you 10,000 reputation for free and a free draw."

Nonsense, what free 10,000 reputation? That's what I accumulated over a month of beatings. You take it away and give it back, and it becomes a free gift. Indeed, as the ancients said, game systems are a pit. Logan was full of resentment.

"Host, do you want to draw now?"

"System, what are the prizes?"

"There are jutsu, bloodline limits, artifacts, weapons, and supplies."

"Then open the draw interface."

"Actually, host, you can think it in your mind without speaking aloud."

Damn, why didn't you say that earlier? I even found a place where no one was, afraid that people would think I was crazy if they heard me talking to myself, Logan complained.

"System, open the draw!"

I thought in my mind.

"Draw interface opened. Do you want to start the draw?"

Looking at the prizes in the draw interface, Logan drooled again. Sharingan, Wood Style, Kusanagi, Flying Thunder God, hmm? What's this? There are also explosive tags, shuriken, and soldier pills. Damn, why are most of them junk? Sigh, of course, they won't let you reach the top in one step. It's time to rely on luck. Close your eyes and go for it.

"Start."

"Draw countdown: 3, 2, 1, start."

Logan closed his eyes nervously, muttering.

"Amitabha, give me Sharingan, give me Wood Style, give me Flying Thunder God..."

"Ding, congratulations, host, you got Sharingan. Please choose the source of the Sharingan!"

"Yosh, today's a good day. What source of Sharingan?"

"Choose whose Sharingan to use."

"What options are there?"

"All Sharingan from Naruto can be chosen."

"Yosh, great. I choose Obito Uchiha's."

"Choice complete. Host, do you want to change now?"

"Change, change, hurry up. But system, how many tomoe does it have?"

"Host, it's one tomoe. However, since you just activated the system, the system will give you a discount. 10,000 reputation for two tomoe."

"Then how much normally for two tomoe?"

"Normally, it's 100,000 reputation."

Damn, grand opening sale, big discount.

"Change, change, hurry up and change."

"Okay, starting to change your Sharingan. Please close your eyes. Change complete in ten seconds."

"Okay, okay, hurry up."

"Sharingan change in progress. Countdown: 3, 2, 1, change complete. Host, you can open your eyes."

Feeling a slight pain in his eyes, Logan opened them. He noticed his vision was much better. He could see the legs of insects on distant trees clearly, and birds seemed to fly much slower. Not bad, not bad. Once he adapts, his survival skills will be much stronger. Unfortunately, he can't copy jutsu with the Sharingan, but he can copy taijutsu. Maybe he can try to copy Haki. Yes, he should try with Garp.

"System, I have a question."

"Host, please ask. I can answer within my limits."

Limits? Damn, limits.

"System, can my Sharingan evolve on its own? Can it also cast genjutsu?"

"Host can evolve it on your own or exchange it in the system. Any Sharingan can cast genjutsu, but the strength of the genjutsu depends on the user's talent."

"Then can I evolve it to the Mangekyou Sharingan?"

"Yes, host."

"Will I go blind from overusing the Mangekyou Sharingan?"

"Yes, to avoid blindness, you need to evolve it to the Eternal Mangekyou Sharingan or have the Sage Mode of Hashirama Senju."

Damn, I knew it.

"Then how much reputation for the Eternal Mangekyou Sharingan?"

"100 million reputation."

"How much for the Sage Mode of Hashirama Senju?"

"100 million reputation."

"WTF, that high? What are the ways to earn reputation?"

"Host, you can earn reputation by defeating different enemies, buying reputation with money (1 berry equals 1 reputation), or hunting pirates (the bounty is the reputation)."

"Is defeating and killing the same reputation?"

"No, for example, if you defeat a pirate with a 10 million bounty, you get 10 million reputation. If you kill them, you get 12 million reputation."

"Tsk, tsk, this is encouraging me to kill pirates, isn't it?"

"Does defeating Marines also give reputation?"

"Yes, as long as you defeat an opponent, you get reputation."

"Then how much reputation for Marine officers?"

"Below major, 1 million reputation; major, 2 million reputation; colonel, 5 million reputation; general, 10 million reputation; rear admiral, 100 million reputation; vice admiral, 200 million reputation; admiral, 500 million reputation; fleet admiral, 1 billion reputation."

Considering this, it seems joining the Marines would be better for me to earn reputation. The bounties of pirates in this era are generally not high. For example, the World Destroyer, Wadou, had a bounty of only 500 million, which doesn't match his strength, Logan thought.

I should deal with those Marine officers. There are many of them, and it's the fastest way to earn reputation.

"System, check how much reputation is needed for the Rinnegan, Wood Style, and Flying Thunder God."

"Ding, host's permission is not high enough to check."

"What? What permission do I have?"

"Host has the lowest permission, then medium, high, and supreme. The Rinnegan, Wood Style, and Flying Thunder God are high permission, which you cannot check yet."

Damn system, permission dog, Logan cursed.

"Then how do I unlock permission?"

"Host needs to use reputation to unlock permission. Medium permission requires 1 million reputation, high permission requires 10 million reputation, and supreme permission requires 100 million reputation."

Indeed, no game without paying.

"Then show me what I can exchange with my current permission!"

"Okay, opening the exchange interface for you."

The exchange interface opened, and WTF, what the hell is this?

Soldier Pill: Replenishes stamina, 100 reputation per pill. (Rip-off!)

Explosive Tag: Can be detonated with chakra, 100 reputation per tag.

Shuriken: Essential for ninjas, 100 reputation per shuriken.

...

All junk. Keep looking, hmm, there are jutsu.

Fire Style: Great Fireball Jutsu: C-rank jutsu, 10,000 reputation.

Fire Style: Phoenix Fire Jutsu: C-rank jutsu, 10,000 reputation.

Water Style: Water Disturbance: C-rank jutsu, 10,000 reputation.

Earth Style: Earth Burrowing: C-rank jutsu, 10,000 reputation.

Wind Style: Violent Wind Palm: C-rank jutsu, 10,000 reputation.

Body Flicker Technique: D-rank jutsu, 2,000 reputation.

...

Tsk, tsk, without money, nothing can be done.

"By the way, system, since it's a Naruto system, which elements do I have?"

"The system grants you all elemental affinities as a benefit."

Yosh, this is good. All elemental jutsu, I'll crush them.

"By the way, system, do I have chakra now? How do I use it?"

"After the system's modification, you have chakra. You just need to sense the flow of chakra and guide it out to form hand seals and use jutsu."

"Is that so? I'll try."

Logan focused his mind, sensing the chakra in his body. He slowly felt an active energy flowing through his meridians. Right, I have the Sharingan, I can see it.

He opened his eyes and stared at his hand, seeing a blue chakra flowing rapidly through the meridians. He slowly guided the chakra, making it emerge from his palm, but it quickly dissipated. He needed more training. Shadow Clones would be great.

"Ah, by the way, system, what permission does Shadow Clone belong to?"

"Shadow Clone is a B-rank jutsu, which belongs to medium permission."

Medium permission requires 1 million reputation to unlock, and it would probably cost another 1 million to exchange. So I need 2 million reputation. Sigh, the 10,000 reputation I earned over a month and a half is nothing. 2 million will take a long time. I need to find another way, Logan's head hurt.

"System, can you exist without me?"

Bugs, I need to find bugs. No system is without bugs. I need to exploit them for benefits.

"No, I am bound to you. If you die, I will self-destruct."

Haha, great, a bug. This is a backdoor.

"System, as a beginner in this world full of freaks, I need some survival skills. You don't want me to die before I grow strong, do you? Then you'll be gone too. So, system, can you give me some benefits within your permission? I'll pay you back double later if you want."

"..."

He didn't refuse immediately, so there's hope. I need to push harder.

"System, we are one now. You don't want to die before I grow strong, do you? Even pirated games give you a dragon-slaying weapon at the start. You are top-tier, so you should give me something, right?"

"Host, you have a point, but the system can't give you anything for free. The system can give you a free physical enhancement to the level of a jonin."

Jonin? Not bad, I need it!

"Hurry, system, enhance me!"

"Host, please prepare. Physical enhancement countdown: 3, 2, 1, enhancement starts."

At this moment, Logan felt like millions of ants were biting him, both painful and itchy. Damn, so painful. The damn system didn't even warn me. He gritted his teeth and endured for ten minutes until the pain and itch slowly subsided. He could clearly feel his body was different. Sensing his chakra, it had increased several times. People in the One Piece world were already much stronger, and now Logan should be on par with a typical Marine general.

And the system said it couldn't give anything for free? That means I can owe it?

"Can I owe it? I have the body but no jutsu, so I can't beat anyone."

"If you owe it, you need to pay double the reputation, and if you don't pay within the deadline, all future purchases will cost double. Have you considered it, host?"

Damn, I just thought the system was generous, but now it's a pit again.

"How long is the deadline? If I have to pay double, a short deadline won't be enough."

I need to exploit more.

"It depends on how much reputation you owe."

"How much for medium permission and a few jutsu?"

"If you owe 10 million reputation, given your current situation, the deadline can be six months."

"What about 20 million?"

"Nine months for 20 million."

Damn, I thought it would be a year.

"20 million reputation for nine months, so 10 million reputation to use. 1 million for medium permission, leaving 9 million, which should be enough for what I need. Okay, system, I choose 20 million."

"Understood, host, please receive 10 million reputation."

"Ding, 10 million reputation received."

"System, unlock medium permission."

"Medium permission unlocking, successful."

"Open the exchange interface."

"Exchange interface opened."

Logan browsed the medium permission exchange interface, looking for what he could use now.

Hmm, three-tomoe Sharingan, 1 million reputation; Shadow Clone, 1 million reputation; Lightning Style: Reinforcement, 1 million reputation; Summoning: Rashomon, 1 million reputation; Water Dragon Bullet, 1 million reputation; Fire Dragon Flame Bullet, 1 million reputation; Toad Surface Shadow Manipulation, 1 million reputation; Phoenix Fire Jutsu, 1 million reputation; Water Disturbance, 1 million reputation; Violent Wind Palm, 1 million reputation; Body Replacement, 1 million reputation.

"System, I've chosen. I choose three-tomoe Sharingan, Shadow Clone, Lightning Style: Reinforcement, Summoning: Rashomon, Water Dragon Bullet, Fire Dragon Flame Bullet, Toad Surface Shadow Manipulation, Phoenix Fire Jutsu, Water Disturbance, Violent Wind Palm, and Body Replacement."

"Understood. Body Replacement is a D-rank jutsu, which the system can give you for free. The total is 7.03 million reputation. Do you confirm the purchase, host?"

"Confirm."

"Purchase successful. 7.03 million reputation deducted. Host, you have 2.97 million reputation left. Please repay the 20 million reputation within nine months, or you will face severe penalties."

After the purchase, Logan's mind was flooded with new knowledge. It took him a while to recover. He couldn't buy so much at once in the future, or he might crash.

But the feeling of getting stronger was intoxicating. He couldn't wait to beat Garp up, but he couldn't use jutsu yet. He would use taijutsu, hahaha.

"Damn Garp, I'm back. Come on, watch me beat you up."

"Damn brat, are you asking for it again? Here comes my righteous fist."
