One Piece:Starts by Collecting Nico Robin

The next morning, early.

Caesar sat on the sofa, quietly gazing at the dark purple Devil Fruit in front of him.

Everyone, already prepared and ready to go, sat around him, all with curious expressions.

"Is this the Dark-Dark Fruit?"

Robin examined the appearance of the Dark-Dark Fruit: "Dark purple... The Flower-Flower Fruit I ate was pink and looked like a flower."

Yamato laughed heartily: "My Dog-Dog Fruit, Model: Okuchi-no-Makami looked like a persimmon. By the way, Caesar, what did your Vampire Fruit look like?"

"It was shaped like an overgrown tomato, mostly purple with a dark red top."

As Caesar spoke, he flipped his hand, and the Dark-Dark Fruit instantly disappeared.

[Collected Item: Devil Fruit (Logia Type·Dark-Dark Fruit)]

[Rarity: S]

[Collection Value: SS]

[Evaluation: The bigger Nika's cheat, the more brutal this black hole cuts!]

[Achievement Unlocked: Collected a Logia Type Devil Fruit]

[Achievement Reward: Masterpiece Upgrade]

Caesar's eyes fell on the achievement reward, and a hint of a smile flashed in his eyes.

This reward was not unexpected, as just two days ago, when he collected the Barrier Fruit, he had also unlocked the achievement for collecting a Paramecia Type Fruit, with the same reward of a Masterpiece Upgrade.

With achievements for Zoan, Logia, and Paramecia Types each rewarding a Masterpiece Upgrade, it was enough to fulfill his vision of collecting all three types of Devil Fruits.

"I never expected this fruit to be in Hanafusa's hands."

Caesar marveled: "That guy didn't sell it?"

"Veteran Pirates are like that. Once they find something rare, their first instinct isn't to sell it but to hide it away, just in case something unexpected happens, so they can quickly rise again with these treasures."

Robin said calmly: "After all, for Pirates, money can always be stolen again, but things like Devil Fruits and famous swords are like real estate. Whether they use them themselves, train their subordinates with them, or trade them with other Pirates for what they want, selling them is the least efficient option."

"True, that guy was, after all, a former Warlord of the Sea..."

Caesar nodded, thinking of Crocodile. When Buggy had just become a Warlord of the Sea, he had borrowed a lot of money from Crocodile.

From the timeline, Crocodile had just gotten out of prison at that time, and yet he still had spare money to lend to Buggy. That guy definitely had a treasure stash.

Thinking about it now, those Warlords of the Sea seemed to be in pretty good financial shape. After all, with the World Government's endorsement, whether they were doing business or stealing money, it was all legal.

Bonney looked at Caesar curiously: "So... what's the use of this fruit?"

"Bonney!"

Kuma gently patted his daughter's little head: "You can't just casually pry into other people's secrets."

"It's not a secret, so there's no harm in talking about it."

Caesar smiled, not minding revealing some weaknesses.

After all, the flaws of the Dark-Dark Fruit had nothing to do with his Light-Dark Fruit.

Not only were the people present trustworthy, but even if someone did betray him and spread the information, it would help him weed out the traitors while also setting a trap for others.

"The ability of the Dark-Dark Fruit can be understood as a small black hole. Compared to other Logia Type Fruits, this fruit has significant drawbacks, such as not being able to elementalize like other fruits."

"Unable to elementalize? That essentially lowers the threshold for Logia Types."

Kuma pondered for a moment: "Although Haki can attack elementalized forms, even so, this ability gives one a significant advantage in battles of the same level."

"Exactly..."

Caesar nodded. For Logia Types, even when facing strong opponents who wield Haki, the only threat comes from direct attacks using Haki.

As for damage like explosions, impacts, or falls, they are meaningless to Logia users.

Kaidou would feel pain if he fell from a height of ten thousand meters, but Kizaru would scatter into photons, Akainu would turn into magma, and Kuzan would shatter into ice. When their elements reconstitute, none of them would suffer any harm.

Such situations are inevitable in battles, especially in fights of the same level. Being able to ignore such damage is a tremendous advantage in itself.

Caesar explained: "The Dark-Dark Fruit isn't incapable of elementalization. Its elementalization itself is a black hole, passively absorbing damage from attacks. In a sense, this damage-absorbing ability is even superior to elementalization. However, this ability comes at a cost—the user experiences pain more acutely than ordinary people."

"Moreover, a person's tolerance for pain and damage has limits. Once a certain threshold is exceeded, it could instantly overwhelm the user, like a collapsing building."

"So, with so many drawbacks, why are you still so fixated on it? What's so special about this fruit?"

Robin smiled gently: "Now that we've covered the drawbacks, let's talk about the advantages?"

"It equally counters all Devil Fruit users and can steal others' abilities."

Caesar casually spread his hands, but his words shocked everyone.

Countering Devil Fruit users is understandable—Sea Prism Stone can do that too. But the ability to steal others' powers? That was something they had never heard of before.

"This means that in the future, if you want to obtain that fruit, you just need to find the corresponding user."

Robin's expression turned serious: "It's a good thing this fruit didn't fall into the hands of the World Government."

Kuma also looked surprised: "No wonder you said obtaining this fruit could accelerate our goal of unifying the seas. Is this the reason? Are you planning to form an army of Devil Fruit users?"

"That's correct..."

Caesar nodded slightly, his gaze falling on the system panel.

At this moment, the Dark-Dark Fruit had completed its upgrade, and a card with a gilded border hovered in his vision.

[Collected Item: Devil Fruit (Light-Dark Fruit)]

As for the Elemental Bat, it had never appeared in the game, and Caesar wasn't sure if it could be developed. Currently, no Mythical Zoan had ever demonstrated elemental transformation traits. Even Marco's Phoenix only achieved a pseudo-elemental transformation through the endless Flames of Rebirth.

Caesar had always kept the Elemental Bat as his trump card, intending to surprise his enemies at the right moment. However, he never expected his father-in-law to force it out with a single strike…

[Evaluation: I absorbed the damage, gained the energy, and pain? Nonexistent! Oda doesn't understand a thing about Pirates!]

"System, use the Light-Dark Fruit!"

Caesar's heart raced as the card before him transformed into a stream of light and merged into his body.

Dark energy surged out, resembling black flames, gently flickering on Caesar's shoulder.

"Is this the power of the Dark-Dark Fruit?"

Yamato curiously reached out, her fingertips lightly touching the profound darkness on Caesar's shoulder.

Splat!

As soon as she touched the darkness, her hand seemed to stick to Caesar's shoulder like glue.

"Ah!"

Yamato exclaimed, her entire body drawn by an inexplicable gravitational force, clinging to Caesar like a koala.

"Didn't I tell you? Don't recklessly test abilities you don't understand."

Caesar gave her slender waist a gentle pinch before releasing her.

Yamato grinned. "Hehe, you wouldn't hurt me, right, Caesar?"

"Is this gravity?"

Robin observed the flickering darkness on Caesar's body.

"Ah, let me show you."

Beneath Caesar, a wave of darkness surged out, spreading beneath the coffee table.

Creak—

Bang!

In an instant, the surface of the coffee table cracked and shattered into countless pieces under the violent gravitational force, eventually being completely devoured by the darkness.

Caesar thoughtfully watched the receding darkness, then suddenly turned to Yamato. "Yamato, punch me without using Haki!"

Bang!

As soon as he finished speaking, a heavy punch landed on Caesar's chest.

Caesar remained unmoved, as if the punch were nothing more than a gentle caress.

"Now use Armament Haki and punch me again. Remember…"

Bang!

Another punch landed on Caesar's chest. Yamato blinked. "Huh? Remember what?"

"Remember to go easy…"

Caesar winced in pain, but his body still didn't budge.

He then stood up and, under the puzzled gazes of everyone, walked to the wall, placing his palm gently against it.

Boom—

With a loud explosion, the wall before them shattered in a blinding light, instantly melting under extreme speed and high temperature, leaving a molten path over ten meters long in the manor!

"What the heck is this!"

Bonney's eyes widened. "Isn't this the Dark-Dark Fruit? What does this have to do with darkness? And what was the point of those two punches?"

"Hmm… Sir must have his reasons for doing this!"

Bartolomeo couldn't figure it out either, but that didn't stop him from blindly trusting Caesar.

Caesar smiled but didn't explain.

It was hard to explain something like Black Hole Ejection to a group of people who had never even been to school. In fact, he himself only had a vague understanding of it. He had only discovered this ability because of Yamato's two punches.

From the perspective of the Vampire Fruit's upgrade, although the upgraded fruit has higher numerical values, the enhancement of its abilities still follows basic logic. It's impossible to simply eliminate the drawback of doubled pain. The inherent nature of the Dark-Dark Fruit as a black hole also dictates its characteristic of absorbing attacks, and this drawback cannot vanish without a trace.

Yet, the reality is that the drawback of doubled pain has indeed disappeared, without any cost.

Not only has this drawback vanished, but even without the use of Haki, Yamato's attacks failed to inflict even the slightest damage or pain on Caesar!

While a Haki-infused fist did cause Caesar pain, it was only the normal level of pain.

Moreover, Caesar could clearly feel that the force of Yamato's two heavy punches was perfectly absorbed by his body—the first punch was entirely absorbed, and the second was mostly absorbed, leaving only a negligible amount of force that was insufficient to harm him.

The only plausible explanation Caesar could think of was that the Devil Fruit ability, after its upgrade, had transformed into a true black hole, or at least something much closer to it.

From the original storyline, the Dark-Dark Fruit was more of a Paramecia Type that combined darkness, devouring, and gravitational abilities rather than a true black hole.

A true black hole wouldn't limit its absorption to just the hands or restrict it to non-physical attacks.

According to the nature of a black hole, all incoming attacks would infinitely collapse the moment they approached Blackbeard, torn apart by the immense gravitational force.

The system's evaluation of the Dark-Dark Fruit was quite fitting—just as Oda had given Nika an overpowered ability, the Dark-Dark Fruit had been nerfed just as severely.

However, Caesar could understand this. After all, theoretically, even a cubic centimeter of a black hole could destroy the entire Earth.

The upgraded Dark-Dark Fruit, of course, wasn't at the level of destroying planets, but judging from its Black Hole Ejection ability, Caesar believed it now possessed the characteristics of a true black hole.

To put it simply, if a true black hole were compared to a car, the pre-upgraded Dark-Dark Fruit would be nothing more than a cheap pull-back toy car worth a few dollars.

The upgraded Dark-Dark Fruit, on the other hand, could be likened to a high-end remote-controlled toy car. While it still couldn't compare to a real car, it now possessed the fundamental capabilities of one.

As for the drawback of doubled pain, it had no inherent connection to a black hole.

The upgraded Dark-Dark Fruit could devour everything—matter, energy, even light—into darkness.

However, Caesar wasn't a true black hole, so he couldn't absorb the energy of incoming attacks without sustaining some damage. This energy would accumulate within the dark space inside his body.

Of course, this ability had its limits. Once a certain threshold was reached, it would harm Caesar himself.

Fortunately, he could choose to release this accumulated energy at any time, combining it with his own strength to unleash it in the form of a Dark Ejection.

Having sorted out his thoughts, Caesar finally let out a long sigh of relief.

Indeed, this Dark-Dark Fruit was not consumed in vain!

Even if he couldn't steal abilities, based solely on the characteristics it had now demonstrated, in a one-on-one duel, there was probably no one in the world who could be his match!

Top-tier defense + top-tier physique + top-tier recovery + top-tier Haki + energy absorption + ability suppression…

There might be individuals in the world who could deal more damage than him, such as Shanks or Hawkeye.

But Ca

esar believed that no one in the world could match his health bar, armor thickness, and margin for error!

"Let's go!"

Caesar took a step forward, walking through the hole that had just been blasted into the courtyard.

Snowflakes drifted down from the sky. He looked up and exhaled a faint puff of white mist.

"It's time for us to... conquer the world!"
