It Can Still Be Enhanced

After thinking it through, Mousse realized there was no loophole for him to exploit.

If he wanted to know the contents of the Poneglyph, he would have to find the scholars of Ohara or Oden Kozuki, who should have already returned to Wano Country by now.

However, Mousse was not particularly interested in Laugh Tale's secrets. Failing to find a loophole only left his curiosity unsatisfied, which made him somewhat uncomfortable. He was nowhere near as disappointed as Charlotte Linlin beside him.

Well, Charlotte Linlin still had the temperament of a child, and her interest in the Poneglyph had only lasted three minutes anyway.

When she heard Mousse say he wanted to test the Book-Book Fruit ability on the Poneglyph, she immediately lowered her head eagerly to watch. Looking at her expression, no one would have guessed that she had been so angry she kept pounding the ground just moments ago.

After stepping outside, Mousse took a deep breath and thoroughly composed himself. Then, as he had done before, he released the Book-Book Fruit's power and directly controlled Big Head. Big Head immediately flew into the air.

At first, Mousse controlled it with the Book-Book Fruit ability. Later, it smugly flew around on its own. Its speed was clearly much faster than before, and it was even more nimble when circling and changing direction, making Charlotte Linlin's eyes shine.

"I feel stronger than ever," Big Head bragged after showing off for a while.

But neither it nor the Charlotte mother and son had expected that this chatterbox would suddenly turn mute before it could even finish that sentence. It merely gaped its huge mouth wide, unable to utter a single word!

Even Charlotte Linlin, its creator, was utterly baffled and had no idea what had gone wrong.

Its master, Mousse, thought for a while before finding a possible reason. His eyes shifted as he said to Big Head, "Try talking again now."

"I... huh? I can talk again!" Big Head discovered that it really could speak again and was instantly overjoyed. But just as it was about to speak once more, it found itself mute again.

After testing it several times, Mousse finally understood.

Smiling, he turned to his mother and pointed at Big Head, which was still holding its breath, explaining the reason to her.

"If I'm not mistaken, it's because I found it annoying just now and didn't want it to keep babbling, which is why it couldn't speak. Hmm, I can directly control it now, but I'm not sure whether that's simply because the connection between us has deepened, or whether it's a special effect produced when the Book-Book Fruit's ability to control books acts on a Homie?"

Either way, this was an enormous surprise, because Big Head had effectively been strengthened by two Devil Fruit abilities at once!

During the return voyage from Pharaohs, Mousse had discovered that, like many Paramecia Devil Fruits, the Book-Book Fruit could actually enhance the "books" corresponding to its power.

However, the enhancement was not as great as that of the Biscuit-Biscuit Fruit, and ordinary books were made of paper. Their hardness and toughness were mediocre at best. Even enhanced to the limit, they could not become a trump card like the Biscuit-Biscuit Fruit, so Mousse had never paid much attention to it.

But things were different now. Big Head, this Homie, was already formidable in itself. Strengthening it would naturally make it even more powerful.

Moreover, perhaps because of the Book-Book Fruit's unique nature, Mousse could selectively enhance specific aspects rather than strengthening all of its abilities across the board, making it far more efficient!

After testing each aspect, Mousse found that the stronger Big Head's ability was, the smaller the improvement it could receive. For example, even after being enhanced, its Rock Assimilation ability could only merge with a stone mountain over four hundred meters tall and transform into a giant six or seven hundred meters tall. Yet weaknesses such as its flying speed could increase by twelve or thirteen times after enhancement!

Then, thinking of Big Head's weight of over three hundred tons and its nearly "indestructible" hardness, Mousse immediately realized that Big Head could inflict astonishing damage simply by flying into people.

Especially after it transformed into its Mini Form, which looked small and exquisite but had not lost any weight whatsoever, it was practically a shrunken Heaven-Overturning Seal!

After saying that, Mousse was about to put Big Head away and test the Heaven-Overturning Seal effect when he suddenly thought of another ability of the Book-Book Fruit. He ordered it to return to its original stone tablet form.

But after staring at it for a moment, Mousse shook his head in disappointment.

However, once Big Head returned to its Mini Form, delight suddenly appeared on Mousse's face again.

Then, this form, which should have been fixed, actually began to change!

"Mousse, Mousse, what are you doing?" Seeing the appearance of Big Head, which had originally resembled a stone seal, begin to change, Charlotte Linlin's childlike curiosity was immediately piqued. She waddled over, plopped down on the ground, and stretched out her head as she asked curiously.

While controlling Big Head's transformation, Mousse answered, "Mom, doesn't my ability let me control books? Not only can I control books and make them move, I can also delete, add, and alter their contents. I can even directly change a book's layout or appearance. So I wanted to change its form, but I never expected this Poneglyph stone tablet to possess some unknown mystery. The Book-Book Fruit's ability is actually ineffective on it. Its main body cannot move at all, and I can't add or remove even a single character. But I immediately remembered that Big Head has a second form, so I had it change back and tried again. As it turns out, not only can this form be changed, it also isn't restricted by its material like ordinary books are. It's clearly a stone tablet, yet it can take forms other than a stone tablet, such as the form of a paper book!"

Under Mousse's control, Big Head ultimately transformed into a scroll, rolled up to the thickness of a bowl's base and over a meter long. Then he retreated to a safe distance and had his mother take out Napoleon to slash Big Head once.

The result was exactly as he had expected. This scroll, which felt no different from ordinary paper, was completely undamaged!

That meant that even if Big Head's appearance changed to resemble a paper book, it was still fundamentally that hard stone tablet and still possessed that astonishing, nearly indestructible hardness!

Afterward, Mousse discovered that the scroll could become hard or soft and change freely according to his thoughts. Another bold idea surged into his mind. I remember a Devil Fruit ability with the same effect. Perhaps this fellow is more than just a Heaven-Overturning Seal?

"Go!" Mousse put on a show and pointed at the Scroll floating before him. It immediately unfurled, straightened, and flew out flat.

Then, a massive boulder taller than Charlotte Linlin was instantly sliced in two. Nothing could stop it in the slightest. Even Charlotte Linlin was stunned. She could never have imagined that this Scroll, which looked soft and felt just as soft, could be so incomparably sharp!

Considering Mousse's pitifully weak strength, even if he were given the strongest Supreme Grade Swords in the world, they probably would not display such astonishing power in his hands, would they?
