One Piece: Nobody knows Devil Fruits better than me.

Chapter 102 I haven't forgotten our promise, and I hope you haven't either.
Its enormous body soared into the sky at an exaggerated speed, covering a distance of several thousand meters in the blink of an eye for the Rooster.

Beneath the Rooster mask, sensing the immense power contained within this body, Roy was filled with emotion.

"The effects of the fusion fruit are indeed worthy of its high acquisition difficulty."

He muttered to himself, but his eyes also revealed the information about the special fruit on his body.

[Tyrannosaurus Rex Fruit LV3]

[Fusing Materials: Pteranodon Fruit + Tyrannosaurus Rex Fruit]

[Fruit Effect - Simultaneously combines the abilities of two ancient species, the 'King of the Sky' Quetzalcoatlus and the 'King of the Ground' Tyrannosaurus Rex, gaining the combined physical attributes and vitality of both, and can undergo three transformations of a Zoan-type Devil Fruit]

Fruit fusion does not change the fruit's 'lineage factor'.

Yes, this is the effect of the 'Fusion Fruit Slot' that he unlocked not long ago.

In short—this slot can fuse all fruits of the same type or with strong correlation, and there is no limit to the number of materials that can be fused.

The combined effect is a perfect superposition of all the combined material effects.

For example, the fruit on the rooster's body right now is just like that.

Its essence contains the full power of the Wind God Pteranodon Fruit Level 4 and the Tyrannosaurus Rex Fruit Level 3.

As mentioned before, the combined use of Devil Fruit abilities is not as simple as one plus one.

Take the Wind God Pteranodon Fruit as an example. Its flight ability and ability to use the wind to achieve high speed are very strong, but in terms of pure muscle strength, it cannot be said to be the most outstanding among similar fruits.

The Tyrannosaurus Rex Fruit is unparalleled in terms of strength and vitality, but it lacks in speed.

The integration of the two directly produced a complementary and even transformative effect.

"Compared to wearing these two fruits alone, my speed and strength are at least 30% greater overall."

Simply put, Roy felt that the basic stat boost from the fusion fruit alone was worth the price of admission.

But that's not the most unique thing about the Fusion Fruit slot.

The most unique feature of this slot is that...
[Additional Fusion Fruit Effect - Ancient King]

[Formed from the fusion of two ancient species, the Tyrannosaurus Rex's aura can suppress other sea, land, and air creatures. The suppression effect increases with the fruit's level and the user's physical strength.]

[It can consume a large amount of stamina in a short time to activate the ancient bloodline, enter the 'ancient form', and unleash stronger power and vitality]

This effect will increase as the fruit's level increases.

Yes.

Fruits created through fruit fusion slots will also have certain additional special effects.

For example, the Tyrannosaurus Rex Fruit that Youji possesses right now has the effect that Robin is currently witnessing.

Firstly, it has a group suppression effect that is very close to Conqueror's Haki.

Secondly, there is the special short-duration combat state known as the 'Ancient Stance'.

"Equivalent to an unshakeable Conqueror's Haki, and a brief 'Devil Fruit Awakening'?"

The Rooster has a simple sense of judgment.

And in the short moment he was pondering...
"boom!"

His figure had once again pierced through the clouds and arrived at a higher place, three thousand meters above the White Sea—the White Sea.

With just one glance, the Rooster spotted the enormous island floating in the air in the distance.

"That's Sky Island!?"

At this moment, Robin, sitting behind the rooster, also turned his gaze to the distant island—although he had already guessed the destination of this trip, seeing it with his own eyes was another matter entirely.

But
"."*2
Both Robin and Rooster fell silent the next moment.

Because they can all see what that sky island looks like.

It is divided into two parts: a smaller part is a sky island formed by island clouds, and a larger part is an earthen island similar to the four seas. The two are connected by a huge cloud river.

Up to this point, everything seemed to be no different from what the Rooster knew.

But the only difference is...
"Lord Rooster, it seems this island has been struck by some kind of natural disaster?"

Robin said hesitantly.

That's right.

At this moment, she could see that there were many buildings on the island.

However, all the buildings were covered with moss and vines, and the entire island was deserted.

What is most shocking is the enormous scars that cover the entire island.

Those were deep, enormous rift valleys.

They spread within the rooster's field of vision, almost tearing the entire massive island of Sky Island to pieces.

"."

After hearing Robin's question, the Rooster did not answer.

He simply flapped his wings again and flew toward the earthen island not far from the sky island.

Unlike the pristine white floating island, this earthen island is covered with enormous trees and looks vibrant with life.

The Rooster was not surprised to see this.

He knew that the island was not originally a floating island in the White Sea, but rather part of 'Gaya Island' that was washed ashore by rising ocean currents four hundred years ago.

According to the original storyline, the ancient golden city of 'Shandora' that he sought existed on this island.

In fact, the Rooster did find 'Shangdora' very quickly.

Or rather, the place where Shandora once lived.

At this moment, deep cracks also exist here.

Among these cracks, one can see some remaining traces—such as a collapsed shrine, a huge earthen and stone base, and even some scattered fragments of gold.

But
The magnificent golden city itself has vanished without a trace.

"No wonder Enel chose to go to Qinghai," the Rooster, who had landed and transformed into human form, murmured to himself as he watched this scene.

The facts speak for themselves.

He arrived too late; everything had already been taken.

And
"It's not just a little bit late."

The Rooster looked around at the traces—even though he wasn't a professional and could only make a rough estimate.

But judging from the thickness of the moss and the mud and sand covering it, he could basically tell that the things here had been taken away at least several decades ago.

"Judging from those huge rifts outside, could it be that the Sky Island suffered some kind of natural disaster decades ago? Is that why the people of the Sky Island all left?"

"And they took the gold with them when they left?"

The Rooster guessed this, thinking of the numerous rift valleys that covered the entire sky island.

But compared to him.

Robin's mindset at this moment was clearly quite different.

“It’s a very old building, at least 1,100 years old.”

At this moment, she arrived at the ruins of an altar—a ravine had passed right through the altar, destroying part of it but leaving its general shape intact.

As an archaeologist, Robin's judgment of time was obviously more accurate, so he became increasingly anxious as he looked at the time.

"Such a precious cultural relic, actually... huh?"

She approached the altar, searching for any potentially valuable traces, but soon began to express her doubt.

"Lord Rooster, this...this mark is..."

Her voice trembled slightly with gravity.

"trace?"

Upon hearing her words, the Rooster, who had been pondering something, also frowned.

He walked to the altar as well, and then saw the spot that Robin was currently looking at.

At this moment, it was clear that part of the altar located beside the rift valley had indeed been destroyed.

However, the edges of the destroyed part were extremely smooth.

Those were clearly not naturally occurring marks.

"Not just it"

At that moment, the Rooster also looked down at the deep rift valley below.

Yes—although from the air, one might only think that these huge rifts on the island were created by some natural disaster.

However, upon closer inspection, one will find that the edges of these rift valleys are also extremely smooth.

“They were carved out—by some unimaginable sharpness.”

The Rooster immediately realized this.

But then, an even stronger sense of disharmony followed.

"A strike this sharp—could it be that a powerful swordsman has fought here?"

"No, that's not right. If it were a battle, the marks wouldn't be just like this."

The Rooster keenly grasped this problem.

Judging from the scale of the cut and the strike, he had no doubt that the mastermind behind the strike was a swordsman far beyond his current understanding—he was certain that neither the most powerful swordsman he had ever seen, Shimotsuki Koshiro, nor 'Momousagi' Gion, could have made such a smooth mark.

If such a powerful person were to engage in combat here, the battle marks they would leave would definitely not be limited to these monotonous slash marks.

Just look at his battle with Zephyr on the Sky Island to see that—if the entire Sky Island isn't leveled, at least most of it will be destroyed, leaving behind even more gruesome marks.

so.
"No battle took place; the marks here were left by the person who made the strike."

Upon realizing this, the Rooster instantly understood something.

"Could it be."

Two wings grew from his back.

[Tyrannosaurus Rex Fruit - Humanoid Form]

The next moment, he soared into the sky again.

His figure rose higher and higher under Robin's questioning gaze. Finally, he almost flew to a place without any clouds, and then looked down.

Subsequently
"!!!"

Even the Rooster, who already had some suspicions, suddenly narrowed its pupils beneath the beast-head mask.

Because from this height, he could see the entire sky island.

That was an incredible scene.

The vast and boundless 'white sea' seemed to have become a giant easel at this moment.

The huge floating island below became the canvas.

On the drawing paper, the countless huge cracks that run through the entire island's ground become brushstrokes.

It records those 'messages' from the past.

My friend, I haven't forgotten our promise.

I hope you are the same.

　Let me explain the Red Earl's question.

　　First, let me clarify that before starting this book, I was a manga reader. I had only seen the theatrical versions of 'Strong World,' 'Z', and 'Stampede,' and I also watched the Chopper's Snow Country spin-off movie with my wife. I only watched 'Stampede' because Ace was in the promotional materials. I'm currently catching up on the theatrical versions, but I haven't finished due to limited manuscript.

　　I've only heard of the character Count Red; I really don't know the specific plot details.
　　In the movie version, the only Devil Fruits I currently plan for the main character's clones to use are the Fusion Fruit and the Float Fruit. I wrote these two after watching the movie. I'm also currently researching whether the Momo Fruit can be given to a clone, but I haven't decided yet (although this fruit is very powerful and easy to use, so I'll probably use it).
　　So, the author did indeed leave out information regarding the Red Earl section; I don't deny it. The content has been revised, and I'll add another chapter to apologize to everyone.

　　He deserves to be scolded; there's nothing more to say about the mess he made.
