Pirates, I'm invincible after becoming Luffy

(Resume the update, my family, I was delayed by something in the past two days. I don’t have any drafts saved, sorry, all the handsome guys and beautiful girls)

"Admiral!" everyone shouted!

"And he's the teacher of the three current admirals of the navy, how powerful is he!" Usopp pointed at the unconscious Zephyr and asked: "Why don't we tie him up?"

"Zeff is no longer a marine. After that incident, Zeffer left the marines. He is a pitiful man anyway. Although he is doing some uncontrollable things now, just leave it to me." Luffy smiled confidently. Zeffer's ending is unpredictable.

"This thing is made of seastone." Robin touched Zephyr's mechanical arm and felt a sense of powerlessness.

"It is indeed seastone."

"If he is an enemy, why not just throw him into the sea?" Zoro said directly.

"I do not want."

"If I cure him, he might kill you."

"But I'm a doctor. I can't just sit there and watch him die." Chopper looked at everyone with firm eyes. As a doctor, it was impossible for him to just watch a patient die.

"Heal him, Chopper. I need his help with something." Luffy gave Chopper a trusting look and believed in him.

"Well, thank you Luffy."

"Well, as a marine, this is only natural."

Soon, in Chopper's medical room, Zephyr made a sound and woke up.

"Luffy, he seems to wake up." Chopper jumped over.

Luffy showed an evil smile (Crooked Mouth Dragon King): "Well, it seems so."

Outside the house, Zoro heard the noise and had already pulled out his knife: "Hey, stinky cook."

"It's really annoying, I know, you stinky green algae head."

"Look, I picked up something incredible." Zoro felt Zephyr's powerful aura, and excitement was revealed in his eyes.

"Are you okay? You don't have to force yourself to stand up." Chopper supported Zephyr who was trying to sit up, a little worried. "You drifted here on the sea, remember?"

Zefa touched his confused head and said, "Well, I know. I am very grateful for your timely treatment. It seems that I have saved my life, doctor."

"My name is Chopper."

"Dr. Chopper, you are a good doctor." Shocked, Chopper was actually given a good...good...doctor card by Zefa!

"I won't be happy even if you praise me! Asshole!" Chopper, as usual, covered his face with his hands in shyness when he was praised.

"You are the captain of this ship, right?" Zephyr looked at Luffy. Obviously, Zephyr didn't recognize Luffy yet. "I have seen many young people like you. I am very good at judging people."

"After all, he is the teacher of most of the people in the navy now, don't you think so, Master Zefa?"

Zefa was stunned for a moment. He didn't expect Luffy to recognize him: "I didn't expect that there are still young people like you who know me. But my name is not Zefa now. My name is Z."

"Uncle, do you want me to take you to the next island?" Luffy was obviously waiting for Zephyr to take action first.

"I have a life card. My companion is looking for me with the life card."

"Uncle, your weapon is so cool, where did you buy it?" The person who said this was obviously Chopper. After all, Luffy is no longer the same Luffy as before.

"This was installed by a crazy navy scientist after a mad pirate chopped off his right hand. It's called a battle crusher. It uses the ability user's weakness, and the prosthetic limb made of seastone takes away their strength, and then uses its powerful firepower to destroy the enemy in one go." Zephyr looked at his right hand and sighed.

"Doctor Chopper, I don't recommend you use such a heavy weapon. It can't be untied without special tools. So it will be very troublesome if it falls into the sea."

"Uncle Zephyr, is the pirate you were talking about the guy who called himself Whitebeard II? I've disliked that guy for a long time. What on earth was the World Government thinking by choosing that guy to be one of the Seven Warlords of the Sea?" Luffy was speechless about the World Government.

"Forget it. I'm not a marine anymore. I'm fighting for my mission now. Boy, after all this talk, I still don't know your name?" Zephyr asked. He became interested in this guy who disliked Whitebeard II.

"It's better not to tell you for both of us. And if you don't know what to do, I recommend you to join the Revolutionary Army. Take a look at these books first." Luffy gave the books given to Dragon to Zephyr.

Zefa did not do anything, but took it and looked at it. The more he read, the more frightened he became: "The assumptions here are really bold. But I still want to try my method first, and we'll talk about it later if it doesn't work. Boy, what is your position in the Revolutionary Army? Why haven't I heard of you?"

"Uncle Zephyr is really extreme, that's all. I am the "Star" of the Revolutionary Army, second only to the leader and the Chief of Staff. But I am also a pirate." Luffy is actually second only to the leader, but Luffy has never officially shown his face. Luffy finally said that he is a pirate.

"Is that so? You are pirates." Zephyr stood up and raised his mechanical arm to attack Luffy. Luffy had been on guard against Zephyr and raised his hand to block the attack.

"Uncle, if you want to fight, go outside. I want to learn a lesson and see if I can recruit you into the Revolutionary Army." Luffy didn't want to repair the ship.

"Straw Hat boy, why did you become a pirate?" Zephyr and Luffy slowly walked out of the medical room.

"To become the Pirate King, of course." Luffy straightened his hat.

"One Piece, you actually said One Piece!" Zephyr clenched his mechanical arm, raised it, and rushed forward quickly. In just a few seconds, he attacked Luffy again.

Seeing this, Zoro and Sanji immediately rushed forward and started attacking. Zephyr was not at all inferior in the 1vs2 match.

"This guy is very powerful!" Chopper said while looking at Zefa. At this time, anyone could see that Zefa was very powerful.

"Brook, let's go too!" Seeing this, Usopp hurried forward to help.

"Yes!"

"No, Zoro, Sanji, Usopp, Brook, you guys step back, I'll fight him. Uncle Zephyr, my name is Monkey D. Luffy, please teach me." Luffy didn't plan to use weapons at first, and stood in front of Zephyr. His height made Luffy very vulnerable.

At this time, Zefa's students also came over by boat: "Are you here? Humph."

A man and a woman jumped off the boat that collided with the Sunny.

"I am Baines Adomir Ain of the New Navy. This pirate ship has been surrounded by our New Navy. Stop resisting, it will only hasten your death."

"I say, Master Zefa, are your companions' brains a little bit not very good? They want to defeat our pirate group with such a small number of people?" Luffy said speechlessly as he looked at Zefa who was already gasping for breath.
