One Piece: Becoming Stronger and Bigger by Becoming a Seven Warlord of the Sea

An hour later, in the house of Judicial Island.

"It's over! Lucci!"

Luffy retracted his outstretched fist, took a deep breath, suppressed the excitement in his heart, looked at Lucci who was lying on the ground, and spoke in a calm voice. This was the strongest enemy he had encountered since he went to sea.

However, in the end, he still won, although the process was difficult.

"I still need to continue to get stronger and stronger until I can easily protect my partners! ୧⍢⃝୨"

Luffy clenched his fist tightly, and his knuckles made a crisp sound. This battle made him experience the truth that there are always people better than you. Everything is in vain in the face of absolute power.

Although he had the observation Haki to predict the attack, he still did not completely dodge Lucci's attack during the battle. After all, Lucci's speed was too fast. Under the blessing of the Navy's Six Styles, Luffy was also very strenuous.

"How is it possible! (⊙o⊙) I was defeated by a little kid like this, I can't accept it", Lucci lay on the ground, blood kept flowing from the corner of his mouth, and except for his eyes, the rest of his body was motionless, like a dead dog.

"Haki? Haki is almost impossible to appear in the first half of the Grand Line, why can this little kid use it so skillfully!" Lucci tried to open his mouth unwillingly, but he couldn't speak out.

At a port somewhere on Judicial Island, the rest of the Straw Hat Pirates were besieged by other navy. Endless people surrounded the Straw Hat Pirates, and everyone was using their full strength to fight back.

"Wahaha! Your knife is good, I'll take it for you", a navy's eyes flashed with a sinister smile, looking at Zoro who was fighting with all his strength and rushed over, stretching out his arm to catch the white blade with his bare hands.

"A Devil Fruit user?! Humph, I've really been underestimated." Zoro put the knife on his waist in his mouth, and the Armament Haki covered the three knives. Although it looked light, it was also domineering.

"Shua!"

The navy who was preparing to attack was about to use the Rust Rust Fruit ability, but his heart was shocked, and a bad premonition came to his mind, which was hard to explain. It seemed that this attack was very dangerous.

"Puchi!"

The blade in Zoro's hand came into close contact with the navy's ability arm. When the navy was about to smugly mock Zoro, he suddenly felt a pain in his arm, and blood rushed from his arm and directly splashed on his face. The intense pain surged in his heart, and he subconsciously took a few steps back and looked at the knife in Zoro's hand with horror.

"Impossible! How could it be possible? Why didn't the swords and knives get destroyed?!" The navy who had the Rust Rust Fruit ability was shocked. His previously invincible ability was actually invalid.

"Hmph, a frog in a well, you don't know how big this world is," Zoro said calmly, and then used the three-sword style to bully him and kill him instantly, leaving him with an incredible look on his face.

"Haki, it's really a good thing! However, I still need to continue to get stronger. I heard that there are monsters in the New World who can use this ability. As the world's number one swordsman, that guy can't be unable to do it!" Zoro frowned while cleaning up ordinary navy soldiers. Looking at the snow-walking blade in his hand that was eroded by the power of the Rust-Rust Fruit, Zoro felt that he had to become stronger.

Three hours later, the navy launched the Demon Slayer Order, attempting to destroy the entire Judicial Island and make it disappear from the map. Just as the Straw Hat Pirates looked desperate and panicked around, an ethereal voice appeared in the minds of Luffy and Usopp under the turbulent sea current vortex, and then all the people in the Straw Hat Pirates felt a voice calling them.

"Hehe, everyone, jump down!" Luffy found a ham from somewhere and was eating it happily. Because of his improved strength, he did not suffer fatal injuries after defeating Lucci. After resting for a while and recovering his strength, he was half revived.

"Jump down!" Usopp, who was always timid, jumped down from the high platform behind Luffy, and the rest of the Straw Hat Pirates also jumped down one after another. They believed in their partners.

...

Five days later, in the Seven Waters, Luffy was recovering his vitality and eating and drinking. His rubber arms stretched out quickly and stuffed all the food on the table into his mouth. Under the stunned expressions of everyone, he quickly consumed the food served again and again.

At the same time, a group of uninvited guests came to the outskirts of the Seven Waters. Garp, who was ridiculed by Sengoku every day and felt that his old face was difficult to save, urged his dog-headed battleship to slowly dock on the sea. The group came to the hiding place of the Straw Hat Pirates in the Seven Waters with surprised expressions.

"The world outside has turned upside down, and you, kid,And he's eating so peacefully!" Garp rubbed his fists, and his armament Haki unconsciously covered his arms. A beast-like aura enveloped the entire house. Zoro and Sanji immediately became alert, and their eyes swept outside the house, ready for battle, but unfortunately they were still a step slow.

"Luffy!"

"Bang!"

A punch was thrown, and Luffy's mouth, which was full of food, was immediately covered with his hands in a panic. He almost choked to death on the food. He calmed down and swallowed all the food. He looked up at Garp in front of him with a dark face, and the fear in his bones instantly surged into his heart.

"Grandpa, Grandpa!"

Luffy retreated a few steps in panic, stood up carefully, and subconsciously wanted to escape, even if he learned Haki.

Because the punch just now was too painful, his Haki could not stop his grandfather's Haki fist full of love. The heart-wrenching feeling reminded him of the fear of being dominated.

"Grandpa? ! The Vice Admiral of the Navy is Luffy's grandfather! "

"Everyone, retreat. Don't attack. We will die!" Luffy remembered something and hurriedly shouted to Zoro and the others to retreat.

"Hmph, Luffy, is there anyone who says this about his grandfather? Ah!" Garp's face darkened and he wanted to continue to scold Luffy.

"Grandpa always trains you two brothers to make you excellent navy. What about you, ah, little bastards, one more outrageous than the other, do you take my words to heart!"

"Hmph, I don't care, I just want to be a pirate! I am the man who wants to be the Pirate King!" When he said this, Luffy was fearless and even forgot his fear. He stepped on the table with one foot, stiffened his neck and argued with Garp, looking unconvinced.

"Ha! You bastard!"

"Boom!"

The grandfather and grandson waved their fists at the same time and collided in front of them. The next moment, Luffy held his fist and tears rolled in his eyes.

"It hurts!"

"Hurt? Hey, hey, that's impossible, Luffy, didn't you use Haki to resist it? "Zoro said in surprise.

"Oh, you little brat also know Haki!" Garp turned his head and looked at Zoro, and Zoro subconsciously held the knife, looking at Garp and felt like a mountain pressing on him.

"By the way, Luffy! Your Haki was taught by Xia Tian, ​​right!" Garp sat down on the chair, looking at the aggrieved Luffy, his face very serious.

"Huh? How did you know! Ahem, Grandpa!" Luffy was about to cover his mouth as soon as he said this, but he was too slow.
