I, the great swordsman, am definitely not a bootlicker

Wano Country, Onigashima, above the dome.

The green algae-headed man brandished three sharp swords and fought back and forth with a huge green dragon circling in the air with moon steps.

The sky was covered with dark clouds, lightning and thunder. Three black knives drew shining arcs in the air, creating sparks on the black dragon's body.

The green dragon twisted its huge body, its scales flashing with dazzling light, and turned its head to spew out blazing flames, trying to devour the swordsman.

The green algae-headed man sometimes swung his sword to avoid the flames, and sometimes dodged in the air.

The Azure Dragon's magic attack was completely ineffective. It roared towards the sky and its huge tail swept out like a whip, carrying unparalleled power.

The green algae head raised his arms, tensed his muscles, and swung his sword suddenly to resist the dragon's tail.

Suddenly, there was a loud earth-shaking noise, and the entire dome began to shake violently.

Although the Moon Step allowed him to fight in the air, standing on the air was not as stable as standing on solid ground. In the mid-air wrestling with the dragon, Green Algae Head was clearly at a disadvantage.

Although the dragon's tail was deflected by the firefly, the green algae head plummeted like a meteor, its feet slamming hard into the ground. The ground instantly sank, and countless cracks appeared on the ground, as if the earth itself couldn't withstand the powerful impact.

Kaido's attack did not stop there, he opened his huge mouth and shouted: "Bad wind!"

Countless wind blades gushed out from the dragon's mouth. The green algae-headed man swung his sword at a very fast speed, and used the same sharp blade to cut out. The sword light was crisscrossing in the air, and the sound of the sword resounded through the world.

……

"What a powerful swordsman!" In a corner of the dome stood a woman wearing a ghost mask, staring at the sky in a daze and couldn't help but exclaim.

Not far from her, a tall man who was also watching the game turned his head to look at her, nodded slightly and greeted her: "Master Yamato."

And further away, countless eyes were watching this showdown.

"He's ridiculously strong. As a fellow supernova of the Worst Generation, he's already left us far behind... So, does his training method really work?" The masked burly man looked at the four-eyed beauty next to him with suspicion.

"Ah...it's...useful..." The four-eyed beauty blushed slightly.

……

The two top masters who were concentrating on the duel did not pay attention to the attention from the surroundings, but the green algae-headed man's face gradually showed a little impatience.

"Hey! Old Loach! There's no point in testing people like this. It's time to end the warm-up!"

As soon as he finished speaking, he suddenly swung his sword, and the huge sword light cut off all the wind blades. Then he leaped into the air, his figure was like a phantom, and he rushed towards the dragon at a high speed with a strong wind.

The dragon roared, opened its bloody mouth, and swooped down towards the green algae head like an arrow.

"Two Swords, Two Cuts, Should Climb the Tower"

In an instant, the two sides collided fiercely, and the two black knives suddenly burst out with unparalleled strength, fiercely slashing the dark upper jaw of the dragon, accompanied by the shocking sound of metal colliding.

Immediately afterwards, two loud noises were heard from the ground.

Under the powerful impact of the dragon, the green algae head fell to the ground again.

The dragon was also hit hard on the head and fell to the ground.

For a moment, the ghost island was filled with smoke and dust.

The smoke and dust gradually dissipated, and the dragon's figure disappeared without a trace, replaced by a giant man as tall and strong as an iron tower.

"Oh, haha!" The giant held a huge mace in his hand. Although his eyes were fierce, he laughed wildly. "Kid! You're quite capable! I've been looking forward to a battle like this for a long time!"

As he spoke, a blue-black light emerged from his body, and his body was gradually covered with blue dragon scales. His eyes turned into vertical pupils, and his palms turned into dragon claws. A circle of black smoke swirled behind him.

The green algae-haired man ripped off the scarf on his arm and tied it on his head, then grinned: "Kaido! Use all your strength, otherwise, you will die! ... Ashura Golden Body!"

As soon as he finished speaking, a red light flashed in the green algae-head's eyes and he roared to the sky. At the same time, golden light emerged from his body, and his whole body grew visibly larger like an onion pulled out of dry land, until it became the same size as Kaido.

Although Kaido didn't know what kind of power this was, as one of the Four Emperors, he hadn't felt this kind of oppression for a long time. He became extremely excited: "Oh, haha! Come on! Roronoa!"

At the same time, the mace in Kaido's hand burst out with astonishing dark red lightning, stirring up the wind and clouds. The howling wind alone made it impossible for the people watching from afar to open their eyes.

Endless red lightning also burst out from the green algae-headed sword, and an unparalleled momentum rose into the sky. Countless silver snakes danced wildly in the dark clouds above Onigashima, carrying the dark clouds with them, spreading to the entire Wano Country like the end of the world.

The residents of Wano Country looked towards the sky in panic, while far away in Kyuli, a certain person who was still practicing firefly looked towards Onigashima fiercely and gnashed his teeth: "Damn Zoro! Kaido!!"

Suddenly, there was a huge roar that shook the sky.

The entire Wano Country, with Onigashima as the center, was hit by a two-minute-long earthquake of magnitude 5 or above. The Udon Quarry, which was closest to Onigashima, collapsed on a large scale due to unstable foundations caused by long-term mining. Fortunately, due to the previous disturbance by Luffy and others, a large number of prisoners in the quarry escaped, thus avoiding heavy casualties.

The houses under the dome of Ghost Island collapsed on a large scale, and the wailing sounds continued.

……

Half an hour later...

A rough and wild laugh came from the tallest building on Ghost Island.

"Oh, giggle! It feels so good, fill it up quickly... fill it up again, fill it up again!" Kaido's voice was deafening. He was wrapped in bandages, but it did not affect his momentum and strength at all.

He rolled up his arms and wiped the wine residue on his beard with a rough and bold movement.

In front of him, in addition to a green algae head who put down the sea bowl, there was also a table full of delicious food.

The wine and meat are of the finest quality, and only the most powerful are entitled to enjoy them.

Kaido ate the meat while calling out, "Oh, haha! Come and try some of these unique Wano Country delicacies!"

Green Algae Head ignored him and took another swig from the bowl: "Hmm! This wine is really good!"

"Oh hehe! But then again, Roronoa! Are you really here just to compete with me?" Kaido never understood the behavior of this green-haired guy. After gaining the upper hand, he suddenly said that he didn't want to fight anymore and wanted to drink!

Kaido is better at assessing the situation than Whitebeard and the others, otherwise he wouldn't have conspired with Orochi to delay Oden for five years. So, if he didn't feel that forcing a fight would be embarrassing, Kai would have wanted to give him a couple of blows.

"Well, didn't I say it a long time ago? I'm here to try out some skills." The green algae-headed man grinned.

He really came here to fight the boss. If he wants to defeat Kaido, this tough monster, he will have to fight for at least a day. Besides, if he really kills him, who will help Luffy to enter the fifth gear!

So, as long as the goal is achieved, the new moves have a high strength bonus. Even a strong Kaido in human-beast form can be chopped off with one sword... Although there is no swordsmanship bonus when defeating Kaido, the strength bonus is a little higher than Big Mom, which is quite rewarding.

After Kaido finished another bowl of wine, his eyes were sharp: "What about the Straw Hat Boy? What is your captain's purpose in coming here?"

"He... wanted to knock you away!" The green-haired guy was a real man.

"Oh, hehe! He's still a little short of it if you don't help him." Kaido seems bold, but actually shrewd: "But, why would a man like you follow the Straw Hat Boy?"

"Hey! Being a captain is so tiring." The algae-haired guy rolled his eyes and said, "Hey! Old loach, let me discuss something. I heard you have a daughter. How about asking her to be my girlfriend? Then I won't get involved in the fight between you and Luffy."

Kaido blew his beard when he heard this, and subconsciously reached for the mace beside him. Then he realized something and looked strange: "You want to be my son!?"
