I, the great swordsman, am definitely not a bootlicker

"Joey Boy...is back..."

In the sea far away from Wano Country, the low roar of the ancient giant elephant echoed. The roar of the beast resounded through the sky, and even people as far away as Onigashima could vaguely hear the call from ancient times.

No one knows what it is saying, only Zoro who has awakened to listen to everything, Luffy who is gradually regaining consciousness, and Momonosuke who is still in a frozen state and is dying.

Under the astonished gazes of the crowd, Luffy, his body dyed white, staggered to his feet, seemingly still mumbling in his sleep: "What's going on? I... why can I still stand up... I've already lost, why do I feel happy... Hahahaha..."

Luffy stumbled, fell to the ground, and laughed.

Just as everyone looked at each other in bewilderment and Teacher Gai frowned, Luffy jumped up and, under the reflection of the moonlight, showed a free gesture: "I can do everything I want now! I feel like I can fight for a while longer. The sound of my heartbeat has become so funny. This is my highest realm - Gear Fifth!!"

"What's with the Straw Hat kid's form and that weird laugh?" Kaido looked at the green-haired guy with a puzzled expression. "Is this why you insist on him fighting me?"

The green algae-head nodded and said earnestly: "Well, this is the Joey Boy you have been waiting for."

Kaido suddenly stared at Luffy in the air fiercely. He once set a flag that if anyone could defeat him, that person must be Joy Boy. When the Straw Hat Pirates came to Wano Country, he always thought that Zoro was that person.

"Joey Boy!?" Robin was shocked upon hearing the conversation between the two. "The Joy Boy who left an apology letter on Fishman Island eight hundred years ago?"

"Then... is he still Luffy?" Sanji couldn't help but question when he felt Luffy's temperament change drastically.

"It's Luffy and Joyboy." The green-haired man nodded seriously.

"Zoro, ever since arriving in Wano Country, you've been emphasizing leaving Kaido to Luffy. It's all for this moment, right? What on earth do you know?" Robin looked at the green-haired man in disbelief. "Can you really predict the future?"

Almost everyone turned to look at him, only Tashigi thought it was natural.

The green algae-haired man scratched his head in embarrassment. The future he had predicted was almost over. Before traveling through time, the Straw Hat Pirates had only reached Eggman Island.

"It's not as creepy as you say. I just got some information about Joyboy a long time ago. For eight hundred years, the world government has been trying to reclaim a Devil Fruit that bears the name of God—the Nika Form of the Zoanthropology. Rumor has it that it can give a person's body the ability to become rubber. After awakening, they possess tremendous strength and freedom. They are known as the Liberated Warriors and also as the Sun God. So after seeing Luffy's rubber ability, I had some doubts."

The green algae-headed man started making up stories: "Joey Boy is the owner of this fruit, but no one has been able to awaken this fruit in the past eight hundred years since Joy Boy. But I always believe that as long as there is a strong opponent, Luffy will definitely be able to awaken it."

Robin still had doubts, feeling something was amiss, but the others seemed to have suddenly realized something. Trajafar Law stared blankly at the free figure, "The legendary D?"

"Okay, stop imagining it. After the battle is over, you can just ask Luffy yourself. Let's watch the battle." The green-haired guy quickly asked everyone to sit down and eat melon seeds.

At this time, Kaido looked at Luffy with a gloomy face after landing and said: "I thought you were dead, Straw Hat boy?"

Luffy's awakening ability affected the changes in the surroundings. The entire ground was like a trampoline. While playing, he responded to Kaido: "Aha, haha, I thought I was dead too... Hee, let's put an end to it, Kaido!"

Kaido suddenly transformed into a dragon and bit Luffy.

I don't know whether Luffy didn't want to hide or was caught off guard, but he was swallowed by Teacher Kai in one mouth. However, he regretted it the next second. The Straw Hat Boy was messing around in his stomach, and the giantization made Kaido's dragon body swell up.

Hmm... the melon peel made Kaido's belly big...

The audience was all dumbfounded, their eyes wide open as they watched this bizarre battle.

The man with green algae hair held his forehead slightly, unable to complain about the painting style which was gradually approaching Tom and Jerry.

Teacher Kai's huge body slowly rose up like a hot air balloon, and finally spit out a fat ball. The fat ball also shot into the clouds in the blink of an eye and turned into a giant who cast a pair of supreme slippers that fell from the sky.

This wave of actions made Kaido doubt his life. What was even worse was that Luffy grabbed his head and tail and used him as a jump rope.

Thunder Hand Wen Suo said: "Alas... I can't explain it at all!"

"Such mischievous abilities, matched with such mischievous people..." Usopp covered his eyes and couldn't bear to look.

"For the first time, I feel...that my bastard dad is so pitiful..." Yamato, who was sitting in the crowd, expressed sympathy for Kaido's experience. As one of the Four Emperors, he was actually being fooled by others.

Luo lost his coolness and his eyes popped out.

Finally, Teacher Gai used a heavy hammer - Indra III: Naraku, to knock the naughty Luffy down.

Seeing the white on Luffy gradually fade away, Kaido, who had been hit hard by the continuous blows, also became unstable and fell to one knee: "Hmm... Phew, it's just like the picture in the story. It's quite an interesting performance. However, after all this time, I have reached my limit."

At this time, Luffy gradually became older: "Huh...Huh...I'm so tired...Oh, yes, I almost died just now, this move consumes a lot of energy!"

"...Then you can die without worry. This battle of yours will surely be remembered for eternity."

"I don't care about those false reputations... Huhu... If I really die, there will be only a pile of bones left." Then he muttered about Xiaoyu and Kin'emon... and beat his chest again. The drum of liberation sounded again, returning to gear five.

So, Mr. Gai had to transform into a dragon again. After a fierce battle, Luffy flew across the sky and used the Rubber Monkey Gun to end the battle. Kaido then used the Rising Dragon Flame Bagua to launch a decisive counterattack.

In the end, Luffy, with the vow to feed his friends, punched the dragon in the face. After a long and hard fight, Kaido was finally defeated, lost his last ability to move, and fell into the ground of Wano Country.

At that moment, a bright moon appeared in Wano Country, which was shrouded in dark clouds.

Just as Kaido was about to fall into the lava, he felt his tail being grabbed by a strong hand. After hearing a familiar voice in his ears, he fell into a coma.

"Thank you for your hard work, Teacher Kai. The teaching has ended successfully..."
