One Piece: Navy Traitor, I Marry the Female Emperor To Rule the Sea

Boom! Boom! Boom!

As the battle between Shiro and Red-Haired Shanks began, the entire kingdom of Dressrosa turned into a land of destruction! With the Four Emperors plus the Central Authority's Supreme Commander, a clash of five of the world's top-tier powerhouses shook the heavens and earth!

One of the Seven Warlords of the Sea, the current king of Dressrosa, Doflamingo, had veins bulging on his forehead. He knew that after today, the forces he had painstakingly built over the years would be destroyed.

Though he wanted to intervene and stop the fight between Shiro, Shanks, and the others in Dressrosa, he was powerless to do so. He was simply too weak. That's right. The once-proud Doflamingo, who always considered himself strong, now realized that he was not on the same level as these top-tier powerhouses. Even if he summoned his trump card, the Birdcage, the threads would stand no chance against the attacks of either Shiro or the Four Emperors.

It wasn't just Doflamingo who was stunned, even the members of the Emperor's crew were left speechless. No one could have imagined that the young man named Shiro possessed such terrifying power — the strength to fight two Emperors alone!

The battle with the transformed dragon Kaido and the mighty Whitebeard was a sight to behold. Even the supposed "World's Strongest Creature," Kaido suffered multiple injuries under the relentless assault of Whitebeard.

While Kaido and Whitebeard clashed, the duel between Shiro and Shanks was equally fierce. Their intense clash of Conqueror's Haki engulfed the entire sea area. The two of them, both master swordsmen, were displaying their fearsome skills. Every slash seemed capable of flattening a mountain!

"Shiro, you truly are surprising!" Shanks couldn't help but exclaim in the midst of battle.

Initially, he thought of Shiro as a promising young man with great potential. But as their fight continued, he realized that he was wrong. The man standing before him, the Supreme Commander of the Central Authority, had the strength surpassing even the Emperor!

As Shanks attempted to suppress Shiro using his Conqueror's Haki, he was shocked to feel Shiro's counterattack. Shiro could also use Conqueror's Haki! This was a skill unique to Shanks, something even the strongest like Whitebeard hadn't mastered!

"Shanks, we're not enemies. My goal is the World Government! No matter who you really are, you can't stop me!" Shiro's eyes blazed with determination as he unleashed his full power. He had completely adapted to his god-like physique, his abilities reaching new heights.

Faced with Shiro's overwhelming display, Shanks hesitated. The young man's ambition to overthrow the World Government seemed more real and attainable than ever.

"To overthrow the World Government?" Shanks muttered, his resolve wavering.

Without wasting any time, Shiro unleashed his most powerful lightning strike directly at Shanks. The attack hit its mark, sending the Red-Haired Emperor flying backward. The members of the Red-Haired Pirates were shocked, rushing to check on their captain. Although Shanks was injured, he wasn't severely harmed.

"Pirates of the Emperors' crew, give up your resistance! Those who follow the Central Authority will prosper, those who oppose it will perish!" Shiro roared, his voice echoing across the battlefield as he embodied the thunder god's might, surrounded by swirling lightning, flames, and gales.

After temporarily repelling Shanks, Shiro turned his focus to Kaido, unleashing a powerful assault from both the front and back, while Whitebeard delivered the finishing blow to Big Mom. In a short time, three of the Four Emperors had been heavily injured!

Seeing the tide of battle shift in Shiro's favor, the crew members of the Emperors' crews could only watch in fear and trepidation. Even though they were considered strong in their own right, they were no match for the likes of Shiro and Whitebeard.

"I'm sorry, Kaido, Big Mom," Shanks said, drawing his sword once more. "Shiro is not a reckless fighter. If he's here, he must have a larger plan. Leave with your crews; I'll hold them off."

Despite Shanks's words, Kaido and Big Mom had no intention of continuing the battle. Initially, they were convinced by Shanks to join this chaotic confrontation, but now, with Whitebeard back to his peak and Shiro displaying such fearsome strength, they knew retreat was the wiser option.

Just as Kaido and Big Mom were about to board their ships to leave, however, a sudden twist occurred!
