One Piece: Enhanced Supreme Grade Sword

"Go ask Sentomaru."

As he spoke, he took out a Den Den Mushi from his person. As for why he didn't put the Den Den Mushi in his spatial ring...

That's because he was afraid that the Den Den Mushi would "mutate" inside the spatial ring.

The magic beans I put in have sprouted and are growing.

Who knows what will happen if you put a Den Den Mushi in there? Besides, you can't hear anything even if you put it in.

The call connected quickly. After giving her name, Hill asked the Den Den Mushi, "Sentomaru, are the Pacifistas able to talk because of the Enhancement Stone?!"

The Den Den Mushi perfectly mimicked Sentomaru's puzzled expression, saying, "Yeah, even though Pacifistas aren't being produced anymore, all the Pacifistas that were made before have been upgraded! Didn't you know that?!"

I really don't know.

Hill then asked, "Pacifistas can speak after being upgraded, so are there any examples of mobile armors speaking after being upgraded?!"

The Den Den Mushi in his hand mimicked Sentomaru's even more puzzled expression, with all the features on his face seemingly scrunched up together.

"Doctor...don't you know that mobile armor cannot be upgraded?!"

Can't be enhanced?!

Hilton was taken aback when he heard Sentomaru's answer. There was no doubt that what Sentomaru said was 100% true.

After all, he was extremely familiar with that big-mouthed guy.

Hill said, "I understand, that's all, bye."

After saying that, he hung up the phone.

What's going on here?!

A question arose in my mind: "Why can't they enhance theirs when I can enhance Ink Dragon No. 1 myself?!"

Hill was also asking the system in his mind.

The system responded: "All items produced by the system, whether crafted or obtained through a lottery, cannot be enhanced by anyone other than the host!"

Hearing the system's explanation.

Hill finally understood that everything produced by the system could only be enhanced by that person, and no one else could.

Therefore, only the individual can enhance the mobile armor.

Wouldn't that mean the +12 enhanced Mo Long No. 1 is the only one of its kind?!

Feeling somewhat disappointed, he thought, "It seems impossible to use the power of the Lucky Fruit to enhance my items..."

"Then I'll have to strengthen myself."

Hill had originally planned to use the power of the Lucky Fruit to enhance his items and save on enhancement stones and guaranteed enhancement scrolls, but now it seems that won't work.

He took the key and opened the warehouse door in front of him.

It was completely empty inside, and very large, about half the size of a football field.

Close the door.

He took out the Cat-Cat Fruit, Ancient Zoan, Short Sword Saber-toothed Tiger form, from his spatial ring, his deep, bright eyes filled with anticipation. "Let's strengthen this Devil Fruit first."

This time, he used three Enhancement Scrolls to enhance the fruit to +15.

"Enhancement successful! Congratulations, host, you have obtained Zoan-type Cat-Cat Fruit, Mythical Zoan, Tailfire Tiger form!"

I heard the system notification tone.

Hill was overjoyed, his heart bursting with happiness. "Haha...it really is a Mythical Zoan Devil Fruit."

His laughter echoed through the empty warehouse.

The Devil Fruit in his hand also changed its appearance, turning orange-yellow and resembling the shape of flames.

It is likely a mythical beast species capable of controlling fire.

Looking at the Devil Fruit in his hand, Hill did not immediately choose to eat it; he had another idea in mind.

That means continuing to strengthen it.

"Perfect timing to try out the +1 enhancement stone in my spatial ring."

Chapter 103 The Four Celestial Spirits – White Tiger

Hill took out the +1 enhancement stone from his spatial ring. He had used a "Level Scroll +1" to create this +1 enhancement stone inexplicably.

With the horse talisman in hand, he had no worries.

"The enhancement and upgrade of this Devil Fruit was fairly standard at first, but it changed a bit after it reached the Mythical Zoan level. The Tailfire Tiger is one of the Twenty-Eight Constellations in ancient mythology."

"That can be considered a Chinese myth."

This also excited Hill, filling him with anticipation. "I wonder what kind of ability it will become if it continues to be strengthened. Perhaps an even more powerful mythical creature will emerge."

Suppressing his excitement, Hill began to strengthen himself.

The light produced by the +1 enhancement stone fusion was several times stronger than that of an ordinary enhancement stone.

The entire dimly lit warehouse was illuminated by this intense light.

The enhancement stones were gradually incorporated into the Devil Fruit.

Finally, it disappeared completely.

"Holy crap, the enhancement was a success!!!" Hill was so happy that she danced around. The Devil Fruit had been enhanced to +16.

To date, and into the future.

This is the highest enhancement level ever achieved.

At this moment, a notification sound also came from the system.

"Enhancement successful! Congratulations, host, you have obtained the Zoan-type Cat-Cat Fruit, Mythical Zoan, Bi'an form!"

"It's been upgraded again?!"

Cool!!

Hill's face turned bright red, entirely from joy. Bi'an was the fourth of the nine sons of the dragon in legend.

How could it not be amazing?!

Ancient texts say: "The fourth is the Bi'an, which resembles a tiger and has great power, so it is placed at the prison gate."

Hill's expression was radiant, his eyes sparkling with excitement. "Wait... this is only +16... incredible, amazing! If it continues to be strengthened, what kind of mythical beast will it become?"

"Nika form? It's all trash."

"I just used an enhancement stone to enhance it by +1, so let's use a level scroll to upgrade the enhancement stone's level again."

He hurriedly took out the remaining four level-up scrolls from his spatial ring.

Looking at the level-up scroll in her hand, Hill murmured, "Could it be fate? Is it going to upgrade me to level 20?!"

He won 10 level-up scrolls in the last lottery, but he used 6 of them to upgrade his skill levels.

Now there are only 4 left.

It also requires 4 enhancements to upgrade from level 16 to 20.

Regardless of fate, Hill immediately began using level-up scrolls on the enhancement stones.

Enhancement Stone +1.

······

Enhancement Stone +4.

"You can't use enhancement stones to enhance other enhancement stones. You can only use level-up scrolls to upgrade the level of enhancement stones. But is there really a 100% success rate with these scrolls?!" Hill wondered.

"Never mind, failure is failure. Anyway, +16 is not bad."

With a heavy heart.

He immediately used the +4 enhancement stone to start enhancing the Devil Fruit.

The light emitted by the enhanced stone was as dazzling as the aurora borealis.

Hill squinted, watching the enhancement process through his slits as the enhancement stone gradually merged into the Devil Fruit.

I couldn't help but feel uneasy.

His expression was tense yet filled with intense anticipation; time seemed to slow down at that moment.

As soon as the enhancement stone was incorporated into the Devil Fruit, Hill's nerves tightened even more, fearing that failure might occur.

He began to pray incessantly: "It must succeed! Whether or not Jack Ma is involved, it must succeed! Guanyin Bodhisattva, please bless it, it must succeed..."

I was so nervous that sweat started to pour from my forehead.

Time passed second by second, as if the hands of time had stopped.

Hill endured the blinding light as he watched the enhancement stone gradually merge into the Devil Fruit, from a corner to half a stone.

His heart was taut.

As the enhancement continued, Hill herself lost track of how much time had passed, watching as the last tiny bit of the enhancement stone completely merged into the Devil Fruit.

Hilton breathed a sigh of relief, followed by boundless elation.

"It's done, holy crap!!!"

"It really worked!!"

"Brilliant!!"

"A Devil Fruit with +20 enhancement!!"

"Aaaaaah~!!!!"

"I really am the protagonist!!"

"・・・"

Anyone who has experienced this kind of exhilarating feeling knows it; Hill was so excited that he screamed.

Clenching his fists, he punched the air.
