One Piece: Infinite Treasure Chest System.

"Wing Barrage!"

The moment the mission activated, Ben unleashed Mostima's ability.

Countless razor-sharp feathers rained down, tearing through the Celestial Dragon's guards like paper.

"Heh. And you thought I'd be your mount? Just because I didn't want to provoke you doesn't mean I was afraid of you, Char Marco Saint!"

With those words, Ben fired a single feather straight at Char Marco Saint's arm.

"Clang!"

A tall, sunglasses-wearing bodyguard standing beside the Celestial Dragon intercepted the attack.

"A filthy commoner like you should be grateful Saint even looked your way. If you refuse to kneel, then I'll educate you properly."

The guard unsheathed his longsword, its blade quickly coated in Armament Haki.

Ben's eyes narrowed.

So that's why his attack was blocked. This guy wasn't just any lackey—he was a skilled Haki user. And there was something else… a faint, oppressive aura surrounding him.

"Haki, huh? I can use it too."

Ben drew his blade—Senbonzakura. He tried to coat it with Haki… but for some reason, the blade refused to take it.

"Clang!"

The two swords clashed, sparks flying.

"Not bad, kid. But you're still way out of your league." The man smirked. "Let me, Karl Ralt, show you what true failure looks like. Heavy Blade—Cleave!"

With a single, powerful strike, he sent Ben flying.

Ben crashed onto the ground but quickly picked himself up.

"Scatter, Senbonzakura."

As he spoke, his blade disintegrated into a thousand floating petals—each one a deadly razor-sharp fragment.

With a single wave of his hand, they swarmed toward Karl Ralt in a deadly dance.

"Tekkai!"

Karl Ralt activated Tekkai, the Iron Body technique from Rokushiki, bracing himself for the impact.

But the expected clash never came.

Instead, the cherry blossom-like blades sank directly into his body.

A moment later, Karl Ralt collapsed.

No wounds. No blood.

"Huh?"

Ben stared at the scene, completely baffled. This didn't happen when he fought against Qing Niu and Long She before…

Then, it hit him.

Senbonzakura wasn't just any blade—it was a Zanpakutō.

It didn't cut flesh. It severed souls.

Maybe his increased spiritual energy allowed him to target souls directly. Or perhaps Zanpakutō could only affect human souls to begin with.

Whatever the reason, it wasn't a bad thing for him.

Karl Ralt's lifeless body slumped to the ground.

The three remaining bodyguards immediately stepped in front of Char Marco Saint.

"Char Marco Saint, I don't care what your status is, but I'm warning you—don't mess with me!"

"Ki-Kill this criminal now!"

The three guards lunged at Ben.

"Scatter, Senbonzakura!"

The air filled with shimmering pink petals.

A moment later, the guards collapsed, shredded beyond recognition.

But after using Shikai twice in quick succession, Ben felt his head spinning. Damn… looks like using Senbonzakura burns through my spiritual energy faster than I thought.

"No… No! I'm a Celestial Dragon! You can't kill me!" Char Marco Saint screamed, his face contorted in panic. "You worthless peasants! Kill him now! If you take him down, I'll—!"

"Flying Feather—Pierce!"

A single razor-sharp feather shot through Char Marco Saint's left arm.

"AAAAHHHHH!!"

"You… You fools! If I die, you all die with me!" The wounded noble screeched at the cowering civilians.

At his words, the townspeople hesitated—then, one by one, they picked up makeshift weapons. Even children clutched toy swords with trembling hands.

Ben sighed.

This is how it is in this world. Under the Celestial Dragons and the World Government's rule, these people have been completely broken.

The moment someone defies them, the Marines will come down like a hammer.

"I told you—don't mess with me. But I'll let you go this time."

Ben had no intention of hurting innocent people, so he spread his wings and took off into the sky.

After leaving the central district, Ben knew he couldn't stay in the Goa Kingdom much longer. He immediately resumed his treasure chest hunt.

Soon, rumors spread across the city.

A mysterious figure had been appearing in homes and palaces, yet he stole nothing—he just left as suddenly as he arrived.

And people knew exactly who he was.

The flying man who had injured Char Marco Saint.

But no one reported him.

To the common folk, Ben had done nothing wrong. In fact, thanks to him, the Celestial Dragons had retreated to the palace, no longer forcing the townspeople to kneel in the streets.

The nobles and royal guards attempted to hunt him down, but Ben easily evaded them every time.

Three days later, after looting the royal treasury, he changed his appearance and boarded a merchant ship bound for Orange Town.

The nearest island.

And more importantly… that's where little Nami is.

Not only could he see if he could recruit Luffy's future navigator, but let's be real—he had zero navigation skills himself.

Now, sitting in his cabin, Ben looked at the mountain of treasure chests in front of him.

During his sweep of the Goa Kingdom, he had collected:

20 Black Iron Chests3 Bronze Chests1 Special Chest1 Random Chest

This was the first time he'd ever held onto so many chests without opening them immediately.

"System, open all Black Iron Chests."

[Congratulations! You have obtained:]

[10 Crates of Diamond Cigarettes] (Luxury brand from Earth. Retail price: 50 RMB per pack.)[…][…][The Devil Fruit: Reverse-Return Fruit] (From the One Piece world. Grants the power to rewind a person's age. Other abilities must be discovered by the user.)

Whoa!

He hadn't expected to pull a Devil Fruit out of this haul. And not just any fruit—one of the most broken abilities in One Piece!

Back when he watched the anime, he always thought the Reverse-Return Fruit had massive potential. Ain used it decently, but in Ben's eyes, she barely scratched the surface.

Sorry, Ain, but I'm taking this one for myself.

He stored the fruit away carefully, then recycled the rest of the items. Except for the diamond cigarettes—he kept those. The tobacco in this world was garbage compared to Earth's.

"System, open the three Bronze Chests."

[Congratulations! You have obtained:]

[Tomorrow's Star] (From a high-magic world. Instantly increases charm by 100 points.)
