Mr.5's eyes flickered slightly, but he quickly regained his sneer. He lightly flicked his finger: "Very good, I'd like to see what you'll use to clean me up!"
Kai slowly raised his halberd (a type of polearm), and his Aura suddenly surged, a powerful field sweeping around him like a hurricane.
Vivi and Nami subconsciously took a few steps back, their breathing catching from his Aura.
Kai said without turning his head, "I'll take care of this disgusting scum."
Mr.5 snorted, flicking his finger, and a booger with a fiery glow flew towards Kai.
A sharp whooshing sound came through the air, and that tiny bomb seemed to contain destructive power.
"Just a trick," Kai sneered, swinging his halberd (a type of polearm) fiercely. A slash swept out, directly exploding the bomb in mid-air.
"Bang—!"
The explosion erupted in mid-air, but the strong air current was suppressed by Kai's Aura, not creating any ripples.
"Is that all you've got?" Kai's voice was cold. His halberd (a type of polearm) trembled slightly, its blade covered in a dark Armament Haki.
"In that case, I'll just kill you, a weakling, on the spot. You won't have any objections, will you?"
Mr.5 was stunned for a moment, but then he sneered, glancing at his opponent as if he had heard an extremely ridiculous joke.
He looked at Kai with disdain, a hint of provocation appearing on his expressionless face: "Just you?"
He muttered in a low voice, full of contempt, "Annoying person, just die for me first."
As soon as he finished speaking, Mr.5's body shot out like a spring, a whooshing sound filling the air.
His movements were as fast as lightning, almost instantly rushing in front of Kai, a wild smile on his lips.
Usopp's back was drenched in cold sweat. Watching Mr.5 rapidly approach, he was so nervous he almost wanted to close his eyes:
"This speed... and this guy is covered in bombs! Can Kai block him?"
Nami nervously embraced Vivi's slender waist, a hint of worry flashing in her eyes, but she quickly regained her composure:
"Don't be afraid, Kai can do it." Her gaze pierced through the crowd, looking at Kai, who was about to receive a fatal blow, a determined expression on her face.
Princess Vivi's face was pale, her hands clenched, her body trembling slightly involuntarily.
But looking at the stern-faced man, her heart was inexplicably filled with trust:
"Kai... he'll be fine, right?" Her voice carried a subtle tremor, yet she forcibly suppressed her fear.
Sanji's face showed a subtle expression. His hands were in his pockets, and a hint of disdain curled at the corner of his mouth: "This guy, who does he think he is? He's just a joke."
Although Zoro was still covered in scars, the Killing Intent in his eyes had not diminished in the slightest.
He slightly parted his lips, a smile playing at the corner of his mouth: "Come on, let's see what kind of tricks this guy can pull."
Kai stood still, expressionless, his gaze even colder.
He took a deep breath, his eyes sharp as knives, as if he had already anticipated Mr.5's next move.
The entire world seemed to freeze at this moment, and the temperature in the air seemed to drop sharply by several degrees.
He didn't rush to counterattack, nor did he try to dodge, but quietly watched Mr.5's rapidly approaching figure.
Every inch of his muscle was quietly accumulating power, every nerve was taut.
A hint of disdain flashed in Mr.5's eyes; he almost felt his victory.
"This situation, I already have victory in my grasp," he thought to himself, raising his hand to strike at Kai, just as he was about to launch his final attack.
Kai suddenly swung his halberd (a type of polearm), a low roar emanating from his throat: "Halberd Technique, Emperor's Fall (Diyun)!"
Instantly, Kai's entire Qi burst forth like an erupting volcano, and dense Armament Haki suddenly covered his halberd (a type of polearm).
The surging airflow distorted the surrounding air. The intense feeling of power almost made Nami and Vivi, standing in the distance, take a few steps back.
The long shaft of the halberd (a type of polearm), guided by Kai's hands, cut through the air, carrying terrifying destructive power as it met the oncoming Mr.5.
The halberd (a type of polearm) blade streaked through the air, accompanied by a low rumble, as if the entire world trembled.
Kai's halberd (a type of polearm) and Mr.5's bomb-like body collided almost simultaneously.
At that moment, the surrounding air seemed to be torn apart. "Boom!!!" A deafening roar instantly echoed throughout the entire desolate mountain.
Mr.5's body had no chance to react and was instantly struck squarely by Kai's halberd (a type of polearm).
Almost at the same moment, Kai's Armament Haki and terrifying power poured out like a torrent.
The Bomb-Bomb Fruit's ability was completely useless against the halberd (a type of polearm) covered in Armament Haki.
Kai's single halberd (a type of polearm) strike created a powerful shockwave that tore through everything in front of him.
The vibrations in the air almost made one's eardrums ache. The ground deeply caved in from the violent tremors, dust flew, and rocks shattered.
The halberd (a type of polearm) in Kai's hand seemed to resonate with the air, its blade striking Mr.5 with immense force.
Mr.5's body was torn to shreds by this single halberd (a type of polearm) strike, like thin paper.
The intense airflow instantly pulverized his body, and even the surrounding ground was blasted open into a deep gully.
The entire scene underwent a cataclysmic change, as if the world was ending.
The battlefield was dead silent, with only the wind rustling through broken branches.
Kai stood still, his gaze as cold as death, still holding his halberd (a type of polearm).
Vivi, Nami, Usopp, and the others beside him were stunned, completely unable to believe what had just happened.
Mr.5 was dead.
There was no remnant, no trace of a body, as if he had never existed.
Not even dust remained, only a huge gully left on the ground, deep, as if it had swallowed everything.
"How, how is this possible..." Vivi's eyes widened in shock, staring blankly at the completely blasted open clearing.
Her heart was pounding exceptionally fast. She had thought Kai would win, but she never expected Mr.5 to be utterly pulverized by Kai's single blow.
Nami's pupils also suddenly contracted. She looked at Kai in disbelief, her eyes filled with awe: "This, this kind of power..."
Usopp even couldn't help but gulp, muttering, "This is the real monster..."
Kai put away his halberd (a type of polearm), his gaze calmly sweeping around, as if everything that had just happened had nothing to do with him.
"This practical combat exercise today not only improved my strength but also allowed me to create a halberd (a type of polearm) technique. I used him to test it out."
Kai said in a low voice, his tone still indifferent, as if he felt no excitement or pleasure.
"But this scum completely lacked the ability to please me. Weaklings are not worthy of contending with me!"
Behind him, Vivi's eyes were filled with Kai's tall and imposing figure.
