"This level is far from enough!" Kai withdrew his halberd and said loudly,
"Show me all the results of your recent hard training!"
"Attack me with the intent to kill me, let me see your resolve!"
"And I will not hold back, I will ignite all your potential, break through yourselves in battle!"
Luffy, Zoro, and Sanji heard Kai's words, and the boiling blood in their bodies surged even higher.
Their already high fighting spirit became even more vigorous, and a determination to overcome everything rose in their hearts.
Seizing the moment while Kai was speaking, Sanji took the opportunity to quickly rush out from the side.
The Armament Haki on his feet faintly glowed with a scorching red light: "Diable Jambe: Collier Shot!"
His figure was like a gust of wind, carrying an intense momentum, kicking directly at Kai's neck.
"Petty tricks," Kai said softly, tapping his foot, his body subtly shifting like flowing water, avoiding Sanji's kick.
At the same time, he counterattacked with a backhand, the tail end of his Sky-Piercing Halberd heavily striking Sanji's abdomen.
"Bang!"
Sanji's body flew out like a cannonball, crashing onto the ground, stirring up a cloud of dust.
Sanji gritted his teeth, stood up clutching his abdomen, spat out a mouthful of blood, but grinned and said, "As expected, it's exhilarating!"
Luffy leaped up, his fist stretched to its limit, Armament Haki covering his fist, striking at Kai with a fierce gust of wind: "Gum-Gum Bullet!"
"Coming head-on?" Kai sneered, raising his Sky-Piercing Halberd high, clashing fiercely with Luffy's fist.
"Boom!"
The aftermath of the collision swept across like a hurricane, the ground cracked, and gravel flew into the sky.
Luffy's body was repelled by the powerful impact, crashing heavily onto the ground, stirring up a cloud of dust.
As Kai stabilized himself, Zoro had already rushed forward again: "Three Sword Style, Tornado!"
He spun his body rapidly, his three swords unleashing powerful sword energy, storming directly towards Kai.
At the same time, Sanji attacked from behind, a "Mutton Shot!" kicking directly at Kai's lower back.
"Interesting," Kai said in a low voice, his Sky-Piercing Halberd swinging violently, a slash tearing through the air, directly cleaving through Zoro's sword energy.
Then, he turned around, raising his foot to meet Sanji's attack, their soles colliding with a dull thud.
"Bang!"
Sanji was kicked away again, but Zoro's sword energy seized the opportunity to close in.
Kai raised his Sky-Piercing Halberd, easily blocking the attack, then struck fiercely, forcing Zoro's body back several steps.
As time passed, the trio's teamwork became more and more synchronized, and the battle grew increasingly intense.
Luffy's "Gum-Gum Gatling" repeatedly struck Kai's Sky-Piercing Halberd, stirring up countless air currents;
Zoro's "Lion's Song" constantly pressed against Kai's defense, but was easily defused by him;
Sanji's "Diable Jambe," though swift, still couldn't break through Kai's offense.
"Too strong!" Luffy panted, his fists trembling slightly, "This guy Kai has no weaknesses!"
"Less talk!" Zoro gritted his teeth, gripping his swords with both hands, "Keep attacking! We'll find an opportunity eventually!"
"Then let's see," Kai smiled slightly, his aura suddenly changing, the Sky-Piercing Halberd in his hand drawing a sharp arc, directly pressing towards the trio.
As time passed, Luffy, Zoro, and Sanji gradually became covered in wounds.
But under their powerful physical recovery, the wounds quickly healed, only to be quickly replaced by new ones.
All three fought with all their might, and their strength grew rapidly during the battle.
The sun set, night fell, but the aftermath of the battle still didn't cease.
The four fought from one end of the desolate mountain to the other, the ground covered in cracks and craters, the wild grass and trees long since overturned by the air currents, and the air filled with the smell of scorched earth.
Sanji finally collapsed from exhaustion, sitting on the ground, panting, forcing out a smile: "It seems I've reached my limit."
He had reached his limit, covered in wounds, and his body's recovery ability was slowly weakening as the battle continued.
Only Kai, Luffy, and Zoro remained on the field.
"Again!" Luffy gritted his teeth, his fists clenched again, covered in wounds but showing no signs of retreat.
"Hmph!" Zoro's chest was covered in scars, his white shirt already in tatters, but his fighting spirit remained fervent.
Both rushed towards Kai simultaneously, their fists and blades carrying their last strength towards their opponent.
"Please... help me!"
A weak voice broke the rhythm of the battle; Miss Wednesday, riding a giant duck, fell down the hillside, covered in wounds.
The few of them paused, their gazes turning to her. Before she could speak further, a deep male voice came from the hillside: "Today, no one can save you!"
In the night, two blurry figures, a man and a woman, slowly appeared.
"Princess Vivi, you really ran fast," the man's tone was low and cold, his gaze sweeping over Kai and the others with a hint of disdain.
"It seems you even found helpers?" the woman chuckled softly, "But these people don't seem like much, all tattered like beggars about to collapse from exhaustion!"
Nami, who was hiding in the distance, heard the commotion and quickly strode over to Vivi, helping the injured Vivi up from the ground.
"Why do they call you Princess Vivi?" Nami asked Vivi curiously.
At this moment, Princess Vivi's slender figure was covered in wounds, her blue hair draped over her shoulders.
Her long and well-proportioned legs were exposed beneath her shorts, but her face, filled with despair and hatred, marred her beauty.
"I am the princess of Alabasta. To find out who is destroying my country and people, I infiltrated Baroque Works!"
"They are Mr. 5 and Miss Valentine from Baroque Works..."
Vivi seemed to grasp at a lifeline, now placing all her hope in the Straw Hat Pirates.
Vivi's miserable expression successfully convinced Nami's sympathy.
The man chasing Vivi walked ahead, a cold sneer on his lips, his hands in his pockets, his confident steps exuding an undeniable aura.
He was Mr. 5, as Vivi called him, a Bomb-Bomb Fruit user, dressed in a dark trench coat, with slightly curly hair and cold, sharp eyes.
The woman followed closely, holding a yellow polka-dotted parasol, her steps light and elegant.
A sweet smile hung on her pretty face, but that smile held a venomous chill.
She was Miss Valentine. Miss Valentine had a slender and tall figure, her long legs appearing even more shapely and alluring beneath her yellow bodycon skirt.
Her golden short hair was neat and smooth, her face delicate, her eyes large and bright, her eyebrows long and curved, and the corners of her mouth slightly upturned, her smile carrying a sweet cunning.
The hem of her yellow bodycon skirt swayed gently with her movements, and the white high heels on her feet added a touch of sexiness and elegance.
