"What were you talking about? I didn't hear clearly, you say it again..."The evil dragon looked at Luffy with a dangerous look in his eyes and asked.

"I said, Nami is my navigator, we're going to get her back!" Luffy repeated again.

"Heh... Haha! How dare you say such a thing in front of me. The dragon smiled.

"Evil, dragon boss, don't listen to his nonsense..."Nami said in a panic when she saw that Luffy had angered the dragon.

"Fuck off, it's none of your business here." But before Nami could finish her words, the dragon grabbed Nami's arm and pushed Nami aside.

Nami was pushed to the ground, her knees and hands were worn by rubble, and blood flowed out, but Nami didn't care about the injuries on her body at all, and wanted to get up and continue to plead with the dragon for Luffy and the others.

"How dare you hurt our navigators!" Luffy saw Nami being pushed down, his eyes immediately widened, Sanji's eyes were on fire, Zoro's expression also changed slightly, and Usopp, who was a little scared, also became angry when he looked at the evil dragon.

'Boom! The next moment, Luffy swung his fist, his arm stretched out more than ten meters, passed through the fishmen, and punched the evil dragon in the face, and the evil dragon was knocked out, crashed through the screen behind him, and was embedded in the wall.

"Ahh Dragon Boss!! The fishmen around him looked incredulous and shocked.

"Devil Fruit power, who are you?" The evil dragon slapped off the gravel on his body, got up from the ground, and ate Luffy's heavy punch, and he didn't look like anything was wrong.

"My name is Luffy, and I'm a pirate! Nami, it's my navigator! Bully my navigator and I'm going to beat you up! Luffy said.

"Unexpectedly, he sent such a strong dragon flying!" Nokigao looked surprised.

"Bastard, you dare to attack the evil dragon boss, brothers, kill them!" The surrounding fishmen came to their senses, and they all drew their weapons and rushed towards Caesar and the others.

"A bunch of little minions, get out of here!" Zoro and Sanji greeted them, and these fishmen, flying back backwards at a faster speed, were not one of their enemies.

The physical fitness of the fish people is indeed naturally stronger than that of humans, but the growth potential of humans is much higher than that of fish people.

Moreover, Zoro and Sanji are both masters of hard work, and the fish people under these evil dragons, following the evil dragons on this island, are powerful, scraping the people's fat and ointment, eating and drinking, they have not exercised much at all, they have been eating their old books, not only have not improved, but have regressed a lot.

Under the battle between the two sides, these fish people are not the opponents of Luffy and the others at all.

"It's just a few inferior races that dare to attack our noble fishmen, you are violating the laws of nature, Hachi..."The evil dragon said, and cried.

Hachi, the dragon's mouth, is an octopus-type fishman with six arms, with a mouth like a trumpet.

"Got it, Lord Dragon, come out! Deep-sea monsters, manatees! Hachi said loudly, making a weird sound from his mouth.

In the middle of the Dragon Park, there is a huge pool with a radius of 100 meters, and this pool is connected to the sea, and in normal times, the fishman will stay in the pool when he has nothing to do.

At this time, this pool bulged, and a huge figure, rushing from the pool, was a giant beast with a body of more than ten meters, which looked like a cow, or the kind of cow with black and white patches, and wore a huge copper ring on its nose.

"Wow! Monsters!! Usopp exclaimed, it was the first time he had seen such a large monster when he had grown so big.

"Oh, it's a sea king, but it's still a juvenile with such a small size." Caesar looked at the manatee and said.

"Lord Caesar, this... Such a big monster, it's still called small!? Usopp said in shock when he heard Caesar's words.

"Of course, the adult sea kings, but they are very large, there are many in the great voyage, generally hundreds of meters, thousands of meters long, the larger sea kings, can swallow the entire island in one bite, and the feces pulled out are enough to form a new island." Caesar's science popularizes the basics.

"Such a small manatee is just a young child who has not been born for a few years." Caesar continued.

"Children of young and early childhood," the corners of Usopp's mouth twitched.

"Woohoo! Whining! Looking at the manatee, Sanji looked at it with a rather strange gaze, his mouth was vague, and he didn't know what he was saying, as if he was assessing which part of the manatee's meat was suitable for what kind of dish.

"Moo!" This manatee, the sound it makes is also very similar to that of a cow, when it appears, it is violent, but after seeing Caesar and the others clearly, it stiffens.

Sanji's eyes when he looked at it made the manatee very uncomfortable, but what made the manatee tremble even more was Caesar, the survival instinct in his body, frantically reminding it to stay away from Caesar.

The manatee did not hesitate, and within a few seconds of appearing, he turned his head away violently, trying to escape.

"Where do you want to go?" The dragon saw that the manatee was trying to run away and spoke.

The manatee shuddered, and its body froze somewhere.

"Well, I won't stop you if you want, but you have to think about it..."The evil dragon said lightly.

"Moo moo moo!" Manatee's eyes flashed with fear, and the fear was greater than the instinct of the body, and he turned around sharply, opened his mouth, and pounced on Caesar and the others with his fangs exposed.

"Ahh Here it comes! The monsters are going to eat us!! Usopp let out a panicked scream, and Nami and Nokigao both trembled with fear.

'Wow! But Caesar raised his head and glanced at the manatee, who had been fierce a second ago, and his eyes turned white in an instant, and he fell into the pool with his belly white.

"Good, good!" Seeing such a big monster, Caesar looked at it and fainted, Usopp exclaimed.

Nami and Noki looked at Caesar's eyes as well, and the dragon was a little surprised.

"Cut, it looks like the opponent has two hits." The fish-man cadres said unhappily when they saw that the manatee had been killed.

"Evil Dragon Boss, just leave it to us, you don't have to make a move, if you do, this Evil Dragon Park will be destroyed by you, and it will be very troublesome to rebuild." The fish-man cadre said to the dragon.

"You get rid of them all, I won't help you unless it's fatal."

"This is a test for you, if you want to become a strong man who can travel all over the world, the number one swordsman in the world, and even One Piece, you need to be strong enough, and fighting is the best way to increase your strength."

Caesar didn't know when, picked up Nami, stood beside Nokigao, and said to Luffy and the others. 10
