The full fight here you go.
---------------------------------------------------
As the battle between Kai and the Golden Lion raged on, the intensity only grew fiercer. The ground of Jaya Island, where Mock Town once stood, had been upturned countless times.
And this was despite most of the fight taking place in the air. If the battle had stayed on the ground, there was no telling what kind of ruin the island would have faced.
Dozens of kilometers away from the battleground, a large crowd had gathered. The moment the fight broke out, the entire town evacuated. Aside from a few unlucky stragglers, everyone else made it to safety.
Now, they all stared at the distant sky, where the battle was taking place. Even though no one could see the fighters from this distance, the shockwaves reaching them and the trembling earth were impossible to ignore.
"What... kind of power is this?" one pirate stammered, his voice shaking.
But no one responded. All of them were too lost in the overwhelming display of destructive force.
"Are there really people this strong?" a pirate with yellow hair and a grotesque smiley face tattoo on his arm muttered, mesmerized by the sight.
Another pirate beside him added, "I was there when the fight started. One of them is the Demon King Kai, with a bounty of 800 million! I don't know who the other guy is, though."
"Eight hundred million?!"
The crowd around him gasped. Their eyes darted toward the yellow-haired pirate—Bellamy, the one with the highest bounty among them, a mere 55 million berries. Even Bellamy's bounty paled in comparison to Kai's.
Just then, another group arrived, looking in awe at the distant battle. Their presence caught everyone's attention as they moved through the crowd.
"Hey, you brat! Quit shoving! You want to die?" one pirate shouted angrily at the group pushing forward.
The group ignored him and kept moving. Enraged, the pirate prepared to teach them a lesson.
But before he could act, his companion grabbed his arm tightly.
"What are you doing?" the pirate snapped, but when he turned to face his friend, he saw the fear in his eyes.
"T-they're the Straw Hat Pirates! Kai's crew!"
"What?!"
The entire crowd looked on in disbelief.
It was Luffy and his crew. Seeing Kai run off earlier, they knew something serious was happening. Despite Kai's orders to wait, their concern drove them to follow him.
But now, they knew they couldn't intervene in this fight. Luffy tilted his head upward, feeling the shockwaves rippling through the air, and muttered softly, "Kai..."
——
"Shiki! You're not the lion you once were. You're nothing more than a shadow of your former self!" Kai taunted as he grinned at the Golden Lion. His words, however, were followed by a sharp pain across his chest, making him wince.
A long, deep slash ran across Kai's upper body, blood spilling from the wound. It was a cut Shiki had landed during their fierce exchange. Fortunately, Kai's body was incredibly resilient. Though the wound appeared severe, it had only sliced through the surface, barely missing bone.
With a mere thought, Kai's injuries began to heal, the flesh knitting itself together before Shiki's eyes, leaving his skin as unblemished as before.
Watching this, Shiki couldn't help but twitch his lips. "Kid, what devil fruit is this? You recover too fast! That's just unfair!"
"Guess!" Kai replied with a smug smile.
Annoyed, Shiki shot him a glare and snapped, "I'm too old to be playing guessing games!"
"Well, tough luck. I'm not telling you!" Kai said, shrugging with an infuriating grin.
"Hahaha… You're a bold one, kid. I like that. How about you join my crew?" Shiki asked, eyeing the wounds on Kai's body. He hadn't expected the young fighter to push him this far. Even in his weakened state, Shiki still had pride in his power. The fact that Kai could keep up was impressive.
"Thanks, but no thanks!" Kai responded coolly. "Besides, you ruined my plans earlier. How could I not kill you for that?"
Shiki's eyes darkened instantly. "Kid, I was going to make you strong, but you're pushing your luck! Don't be so shameless!"
Kai scoffed, "Shameless? My village is called Mangcun—Shamelessness is a badge of honor!"
"You don't need to tell me I can become strong. Even now, I'm capable of leaving my mark on the world!"
Shiki burst into laughter. "Hahaha… You think you're strong? Do you even understand the scale of the seas? In my prime, a brat like you would've stood no chance!"
Kai smirked. "Prime? Past glories don't matter now. Today, you're nothing but a has-been, a wounded relic of the past. You can't even handle someone like me."
Shiki's face darkened further, his patience wearing thin. Without another word, he launched an attack.
"Lion's Thousand-Slice Valley!"
Shiki's legs moved swiftly, sending out a barrage of sword slashes that tore through the air, more potent than any standard cut.
Kai's expression turned serious. This move was dangerous. He needed to be careful or risk severe injury. His clone immediately appeared at his side.
With no way to avoid the attack, Kai decided to meet it head-on.
As the sword slashes approached, Kai's energy surged. His power built up, and with perfect timing, he unleashed it.
"Hakai!"
Kai's attack obliterated the incoming sword waves, neutralizing them as if they were nothing. The remaining sword energy sliced the ocean below, leaving deep fissures in the water.
But Hakai didn't stop after neutralizing the attack. It kept going, surging toward the Golden Lion.
