Chapter 504: Blackbeard, one of the Four Emperors!

Locke's gaze was resolute; he was determined to conquer everything with the power of darkness.

"Luffy, the power of darkness will ultimately triumph over everything! Your courage cannot withstand the torrent of darkness!" Locke responded, his dark energy surging continuously, his sword slicing through the battlefield with dark power.

The battle reached a fever pitch, with each collision releasing intense energy fluctuations. Locke and Luffy were giving it their all, their strength and will clashing fiercely, their resolve unwavering.

Finally, in a fierce collision, Locke and Luffy's attacks reached their peak.

A powerful energy surge erupted across the battlefield, instantly engulfing the entire area. Their gazes met, and their resolve coalesced into an invisible force.

Locke gritted his teeth, dark power surging within him. He let out a low roar and swung his dark sword once more.

Luffy smiled, his entire body radiating the power of rubber. His eyes revealed determination and resolve.

Their attacks collided instantly, unleashing a dazzling light. Darkness and rubbery power intertwined, creating a spectacular scene.

The battle intensified, the battlefield thick with energy. Locke and Luffy engaged in their final duel, displaying extraordinary strength and unwavering determination.

"Rock, your dark power may be strong, but I will never admit defeat!" Luffy's voice was full of determination.

"Luffy, the power of darkness will conquer all! You cannot stop me!" Locke's voice was filled with arrogance.

Their fists collided, sending a massive shockwave through the air, tearing the ground apart and filling the air with scorching heat.

After a fierce battle, Locke's Scorching Executor - Labak finally gained an overwhelming advantage.

"Luffy, you were a formidable opponent, but now, you have lost!" Locke's voice was filled with the joy of victory.

Luffy smiled and paid tribute to Locke in celebration of his victory.

"Rock, you are a true strongman, I admire you!" Luffy patted Locke's shoulder hard.

Locke's victory proved his strength and perseverance, demonstrating that he is an undeniable candidate for Pirate King.

"Luffy, you are a true candidate for Pirate King... I hope we can clash again; it will be an even more intense battle then!" Locke said firmly.

Luffy smiled and held Locke's hand tightly.

Locke and the child stepped through the door to the Great Treasure, entering a mysterious space. A mysterious and oppressive atmosphere permeated the surroundings, as if they had entered another world.

Suddenly, a black shadow appeared before them, slowly coalescing into a human figure. It was Blackbeard, one of the Four Emperors—Marshall D. Teach.

“Locke, I have been waiting for you for a long time. Your dark power has caught my attention. Let’s have a real showdown!” Blackbeard said coldly.

Locke stared at Blackbeard, his heart filled with the passion for battle.

“Blackbeard, I challenge you to a duel to see if your dark power is truly invincible!” Locke replied firmly.

The battle was about to begin when Blackbeard unleashed the powerful Dark-Dark Fruit, while Locke used the Evil Purification Mirror - Jeanne d'Arc to copy Blackbeard's abilities.

"Locke, you were able to copy my Dark-Dark Fruit; it seems your strength is indeed not to be underestimated."

Chapter 505: The power of purification will ultimately triumph over darkness!

"But the power of the Dark-Dark Fruit is the true power of a conqueror!" Blackbeard said confidently.

Locke's lips curled into a cold smile.

"Blackbeard, you may not know, but my Dark-Dark Fruit possesses the power to purify darkness. Today, I will use your dark power to defeat you!" Locke's voice was filled with pride and determination.

The battle began, with Locke and Blackbeard's figures rapidly intersecting, unleashing breathtaking attacks. Locke utilized the power of his Copy-Dark Fruit, his fists imbued with dark energy, like blades tearing through space. Blackbeard's Copy-Dark Fruit, on the other hand, granted him limitless destructive power and regenerative abilities.

"Locke, your dark power is indeed strong, but my dark power is invincible!" Blackbeard roared, his body rapidly recovering from the damage he had suffered.

Locke calmly dodged Blackbeard's attacks while looking for an opportunity to counterattack.

“Blackbeard, your Dark-Dark Fruit is indeed powerful, but my Mirror of Evil Purification can purify all darkness!” Locke said in a low voice.

He drew upon Joan of Arc's power, and the mirror emitted an eerie glow. Locke used Joan of Arc's power to begin purifying Blackbeard's dark forces.

Blackbeard felt the pain of his dark power being purified, and his attacks became even more ferocious and relentless. He fought back desperately, but Locke's purifying power grew stronger and stronger, making it impossible to withstand. Each punch caused Blackbeard immense pain as his dark power was completely purified, losing its original strength.

"Blackbeard, your darkness will eventually be purified by me, and you will not be able to resist!" Locke's voice was filled with the joy of victory.

Blackbeard gritted his teeth, his body began to collapse, and the dark smoke gradually dissipated.

"I will not be defeated by you! The power of darkness will never perish!" Blackbeard roared in despair, unleashing a final shockwave of ferocious power.

Locke steadied himself and did his best to block Blackbeard's final attack.

"Blackbeard, your darkness can no longer shake my power of purification!" Locke roared, his power reaching its peak.

Ultimately, Locke completely blocked Blackbeard's attack. As the dark smoke dissipated, Blackbeard collapsed to his knees, his body utterly defeated.

"I...I lost?" Blackbeard said with difficulty.

Locke's gaze was firm as he walked toward Blackbeard and extended his hand.

"Blackbeard, you are a formidable opponent. Accept defeat; the power of purification will ultimately triumph over darkness."

Blackbeard weakly took Locke's hand, his eyes revealing regret.

"Locke, you are a true powerhouse. Your purifying power defeated my darkness. I acknowledge your victory. You deserve to be called a candidate for Pirate King."

Locke smiled and helped Blackbeard up.

"Blackbeard 663, you are also a strong fighter, and I admire your strength. I hope we can fight again; I believe it will be an even more intense battle then!"

Blackbeard nodded, acknowledging Locke's approval.

Locke and the child arrived at the mysterious world within the One Piece, where a fantastical scene unfolded before them. Islands floated in a mysterious sea of ​​clouds, and colorful flowers emitted enchanting fragrances. In this mysterious world, they encountered a solitary and ancient pirate, the legendary Pirate King—Gol D. Roger.

Roger, with his white hair and kind face, seemed to have anticipated Locke's arrival.

Chapter 506: Murasam, unleash your full power!

"Rock, young prodigy, you've finally arrived. I know you're chasing your dream of becoming the Pirate King, and I'm willing to fight you to see if you're worthy of being the true Pirate King." Roger's voice revealed a hint of anticipation.

Locke's eyes were firm; he could feel the powerful aura emanating from Roger.

"Roger, I, Locke, am willing to fight you and see if I can defeat the legendary Pirate King!" Locke's voice was full of challenge.

Roger nodded with a smile, his eyes flashing with fighting spirit.

"Alright, let's have a real duel and decide who is the true Pirate King with our fists and wills!" Roger shouted, raising his arm.

The battle began, and Locke and Roger quickly engaged in a fierce duel. Locke unleashed the power of Time-Shattering Spirit - Murasam, his figure darting across the battlefield as if in a clone. Roger, on the other hand, displayed his legendary strength, his fists like a storm, each punch filled with unparalleled power.

“Locke, your distraction during meals—Murasam—is indeed unpredictable, but I, Roger, will not give up easily!” Roger said with a smile.

Locke murmured, a determination flashing in his eyes.

“Roger, you are a great Pirate King, but I will not back down! I will prove myself with my strength!” Locke replied firmly.

The battle escalated further, with Locke and Roger displaying high morale and increasing the frequency of their attacks, each punch landing with a visceral impact.

"Locke, no matter how powerful your Divine Interference-Murasam is, I will never admit defeat!" Roger gritted his teeth, his whole body radiating a powerful aura.

Locke sensed Roger's determination, took a deep breath, and gathered his strongest power.

"Murasam, unleash your full power!" Locke murmured, his body radiating a mesmerizing light.

Locke launched a full-force attack, his fists imbued with the power of time, striking Roger repeatedly in an instant.

"Roger, this is my final blow!" Locke shouted.

Roger calmly dodged Locke's attacks and then quickly launched a counterattack.

"Ahhh! Locke, I!! Will not lose to anyone!" Roger roared, unleashing his powerful strength.

Their fists collided, each impact releasing tremendous force. Locke's Time-Digesting Divine Soul - Murasam and Roger's legendary power created a chaotic battlefield.

"Roger, your strength is indeed formidable, but my power will surpass all!" Locke roared, his entire body surging with a mesmerizing light.

Roger's eyes gleamed with determination, showing no sign of backing down.

“Locke, your strength is indeed formidable, but I will never admit defeat! I will defeat you with my experience and will!” Roger replied firmly.

The battle reached a fever pitch, each punch unleashing a powerful surge of energy. Locke and Roger fought with all their might, their strength and will clashing, both determined to prevail.

Finally, in a fierce clash, Locke and Roger's attacks reached their climax.

A powerful energy surge erupted across the battlefield, instantly engulfing the entire area. Their gazes met, and their resolve coalesced into an invisible force.

Locke gritted his teeth, his entire body radiating a dazzling light. He concentrated all his strength and launched a final attack on Roger.

Chapter 507: The answer is 'Pons'!

The two fists collided, and a powerful shockwave spread out instantly, as if the air on the battlefield had frozen for a moment.

The battle was finally over; Locke's final blow had struck Roger. Roger staggered back a few steps, slightly out of breath, a satisfied expression on his face.

"Locke, you are a true strongman, I admire you!" Roger patted Locke's shoulder forcefully.

Locke's victory proved his strength and perseverance, demonstrating that he is an undeniable candidate for Pirate King.

"Roger, you are a legendary Pirate King, and I feel honored to have fought you. I hope that one day we can fight side by side again, and that will be an even more intense battle!" Locke said firmly.

Roger smiled and grasped Locke's hand tightly.

Locke and the boy continued exploring the interior of the Great Treasure, where they discovered the ruins of an ancient civilization, containing countless precious pieces of knowledge and history.
