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

Ding! Choice triggered!

Option 1: Annihilate the Blackbeard Pirates, execute Blackbeard Marshall D. Teach, and let the world know the terrifying strength of Central Authority! Reward: Perfect Observation Nullification (theoretically capable of suppressing Observation Haki, growing stronger as the host's power increases!).

Option 2: Defeat the World Government's CP, and in three days, completely occupy Impel Down, Enies Lobby, and Marineford, the core areas of the first half of the Grand Line! Reward: Advanced technology - a ring-area super defense system set!

Special Note: Both options can be completed simultaneously, with rewards given for each!

As soon as Shiro made his appearance and suppressed the Blackbeard Pirates trio, the system triggered these choices!

However, Shiro didn't focus too much on the options. After realizing both tasks could be completed at once, he turned his attention back to the Blackbeard Pirates.

When Blackbeard Marshall D. Teach dared to have ill intentions toward Hancock, his fate was already sealed!

That fate was destruction!

Even before Shiro sensed something wrong at Impel Down, he wasn't overly concerned. After all, he had already prepared a backup plan.

That's why he had dispatched strong warriors like Aokiji, Fujitora, and Enel. Not only because of the vast area of the first half of the Grand Line and the East and South Blue, filled with numerous Marine branch bases, but also because time was tight, requiring multi-directional strikes.

Additionally, Marine Headquarters didn't need too many strong individuals on standby. Before the World Government's recruitment campaign began, Shiro had already deployed the system's awarded ring-area defense system.

So, when he sensed something off, Shiro immediately checked the situation using the defense system.

Naturally, Hancock, Momousagi, and Robin—along with the other key figures—were aware of this system's existence. They had allowed the Blackbeard Pirates and the World Government's secret forces to approach Amazon Lily and Central Authority Headquarters deliberately. Their plan was to lure the enemies into a trap and wipe them out, sending a clear message to the world.

However, what they hadn't anticipated was the World Government's possession of a mysterious device that severed all signals in the area, causing a temporary communication blackout.

Of course, once Shiro discovered the abnormality, the crisis was quickly averted. With Zephyr and Fujitora continuing their sweep of the first half of the Grand Line, Shiro recalled Aokiji and Enel.

Alongside Hawk Eyes and the others, Shiro used the defense system's teleportation passage to instantly return to Amazon Lily. This led to the scene where the Blackbeard Pirates trio were brutally crushed!

"Dear!"

When Hancock saw Shiro, she was overjoyed. Although the situation had still been within her control, there was no denying the charm of her husband arriving like a hero to save her.

"You're not hurt, right? Leave this to me. These guys sure are bold!" Shiro quickly assessed Hancock and, seeing that she was unharmed, turned his gaze towards Blackbeard, who was struggling to get up from the ground.

"Zehahaha..." Blackbeard's usually arrogant and wild laugh had faded, replaced by a nervous chuckle. His eyes showed clear signs of panic. In just a few seconds, countless thoughts raced through his mind.

Could it be... he was betrayed by the World Government?

Was their true purpose to use Shiro to eliminate him?!

But that didn't seem to make sense.

As much as he hated to admit it, the reality was that Shiro's influence and threat to the World Government, as well as his growing reputation across the seas, far surpassed Blackbeard's own.

But now, none of that mattered.

Facing Shiro, a man with a bounty of 5.36 billion Belly, the most wanted criminal in the world, who had even managed to defeat Fleet Admiral Akainu, Blackbeard's chances of survival were slim.

Especially with the world's strongest swordsman, Hawk Eyes Mihawk, and Pirate Empress Boa Hancock standing by.

At this point, it wasn't just a question of retreating with the entire crew intact—Blackbeard wasn't even sure if he could escape with his own life!

"Zehahaha, Shiro, it's all a misunderstanding! You know that, right? When Shiryu and Burgess were killed by you, I didn't seek revenge! In fact, I've been manipulated by the World Government!" Blackbeard, weighing his options, decided to surrender.

As a scheming villain who had spent decades pursuing his goals, Blackbeard wasn't about to throw his life away for the sake of pride. Judging by the current situation, his best option was to submit.

But no matter how conciliatory his tone was, Shiro remained unmoved, his face showing nothing but cold indifference.

In the next instant—

Whoosh!

A blade infused with powerful Armament Haki, emanating the aura of an ancient beast, pierced through the hearts of Avalo Pizarro and Doc Q. Their vital functions were completely destroyed in an instant.

Within seconds, two of Blackbeard's main cadres were dead, unable to put up any resistance!

"Damn it!" Blackbeard's eyes twitched violently. These were two of his key figures! How could they be taken down so easily?

Had they been more prepared, Avalo Pizarro and Doc Q might have been able to hold their own against Shiro for a while. But the key issue was Shiro's overwhelming strength and his surprise attack, which caught them off guard.

"Damn that World Government!" Blackbeard cursed inwardly.

Where was CP0, the so-called most powerful intelligence agency in the world? Was this the extent of their intelligence?!

"Hawk Eyes, Hancock, let's finish this quickly. There's no need to waste time on someone like him," Shiro said, his gaze never once acknowledging Blackbeard as a worthy opponent.

It wasn't that Shiro considered Blackbeard weak—this was simply strategy. Blackbeard was treacherous and dangerous. He needed to be eliminated immediately, leaving no room for future complications.

"Hey! Hawk Eyes! You're the world's strongest swordsman, right? Do you really have the nerve to gang up on me?!" Blackbeard shouted, hoping to provoke Mihawk.

But as expected, before Blackbeard's words even finished, Hawk Eyes had already drawn his sword.

Cold sweat trickled down Blackbeard's spine. Facing Shiro was already difficult enough. If Hawk Eyes and Pirate Empress Boa Hancock joined in, he was doomed!

Rumble—

Just as Blackbeard tried to taunt Mihawk further, a sudden thunderclap echoed.

Amidst flashing arcs of electricity, Shiro appeared half a meter in front of Blackbeard in an instant!

At that moment, Blackbeard's soul nearly left his body!

He tried to activate his Haki to defend against Shiro's next attack, but to his shock, his Observation Haki was completely suppressed at the most crucial moment...
