One Piece: The Navy's Eight-Year-Old Technology Maniac, the Four Emperors Are Crazy

The Red Hair Pirates on the coastline of Marinford naturally also saw the devil fruit in Xia Yu's hand.

Beckman exhaled a puff of smoke and squinted his eyes tightly.

"Shanks, what do you think of this fruit? Is it really that scary?" Beckman asked with suspicion in his eyes.

The Red Hair Pirates' leaders, including Lagiru, also showed doubtful looks one by one.

"That's impossible... a devil fruit can directly give someone the combat power of a super admiral?"

"This sounds too far-fetched!" Lakilu said in disbelief while gnawing on his big elbow.

Red-haired Shanks narrowed his eyes tightly.

"Even the powerful Rubber Fruit that we snatched from the CP organization back then didn't reach the level of the Pirate King!"

"Xia Yu, I know that your technological capabilities are terrifying..."

"But no matter how powerful you are, you can't create a devil fruit that surpasses the Rubber Fruit, a devil fruit that defies the heavens!"

"This time, I bet you will fail!" Red-haired Shanks muttered with his eyes narrowed.

Beckman, who was standing by, also nodded heavily after hearing this.

"I agree with you, Shanks. After all, this fruit ability is simply too incredible!"

"If I practice hard, I could become a Pirate King-level warrior one day. There's also the possibility..."

"After all, there are no useless fruits, only useless people! But, if you say that just by eating this devil fruit, you can directly advance to the level of Pirate King..."

"I have a negative attitude towards this kind of thing!"

"If a real Pirate King-level warrior could be produced by eating an artificial devil fruit, wouldn't the world be in chaos?" Beckman narrowed his eyes and nodded.

On the battlefield, Kaido was stunned when he saw the fruit that Xia Yu took out.

No way?

Could it be that this guy Xia Yu really developed a devil fruit that could make him a Pirate King?

However, when he thought about it, Kaido started laughing...

"Hahaha! I almost got tricked by you, kid!"

"Even if you develop a terrifying devil fruit, what can you do?"

"Devil Fruits, it takes time to develop!" Kaido's entire body, all his previous worries were swept away...

Big Mom burst into laughter.

"mamamama!"

"I want to see, Xia Yu, what ability do you have to directly train a Pirate King-level warrior!"

"If you have the guts, why don't you just let us see it?"

Obviously, Big Mom didn't believe what Xia Yu said at all!

Zhan Guo, after hearing Xia Yu's words, was even more surprised. Is he really that powerful?

But, on second thought, it doesn’t seem very likely!

After all, Dr. Xia Yu has already spent a lot of energy and time to develop an admiral-level Seraph...

How could there be time to develop anything else?

And... it was before that, it made people upgrade to the combat power of One Piece level, such a terrifying thing...

Thinking of this, Zhan Guo sighed...

"Dr. Xia Yu...does this kind of thing really exist?"

Zhan Guo asked helplessly.

Then...Xia Yu's words immediately made Zhan Guo's eyes light up.

"Of course this is true...Uncle Zhan Guo!"

"Since you are so curious about this thing!"

"Shall we start with you?"

The next moment...a devil fruit was thrown directly into Zhan Guo's hands.

When Sengoku saw the devil fruit in his hand, he did not show any happy expression, but instead looked confused.

"Um...Dr. Xia Yu!"

"There's something I didn't tell you, it's so scary you don't know..."

"Whether it is a devil fruit or an artificial devil fruit, a person cannot use it twice, otherwise, the person will die!" Zhan Guo said helplessly.

Sure enough...it was just as I expected.

Dr. Xia Yu, developing a general-level Seraph, has already wasted a lot of time and energy...

Therefore, when developing artificial devil fruits, there will inevitably be oversights...

I want to raise my combat power to the level of Pirate King. If the fruit is strong, I can reach the level of Pirate King by relying on my own combat power without any development.

But Dr. Xia Yu didn't do his basic homework well...

There is simply no time to understand the iron laws of this world!

At this moment, after hearing Zhan Guo's words, Barrett, who was fighting with Zhan Guo, also burst into laughter...

"Hahaha!"

"Dr. Xia Yu, it seems that you are very technologically advanced. However, you know very little about this world..."

"You don't even know this iron rule that everyone knows..."

"I've been staying in your lab for too long...hahaha!"

Barrett laughed loudly and said!

Kaido and others also burst into laughter.

'Hahaha!'

"Dr. Xia Yu, I really didn't expect you to make such a low-level mistake!"

"This is really unexpected..." Kaido said with a big laugh.

Big Mom also covered her stomach and laughed out loud like Kaido...

“mamamama——”

"In this case, the final winner... will still belong to our pirate team, hahahaha!"

However... facing the ridicule of so many people, Xia Yu still had a smiling face.

Chapter 138: Sengoku Eats the Susanoo Fruit

"Even children know this basic common sense. As a doctor, how could I not know it?"

"My devil fruit is compatible with other devil fruits and will not have any side effects!" Xia Yu said confidently.

what? !

After hearing Xia Yu's words, not only the pirates, but also the navy on the entire battlefield, all showed expressions of shock.

"How can one person eat two devil fruits?"

"This kind of thing is simply impossible!"

"Yes... This sea has been through countless trials and tribulations. Anyone who tries to eat two devil fruits at once will surely die..."

"Dr. Xia Yu, please don't make a mistake, otherwise, people will die..."

The sailors on the entire battlefield said this in confusion.

The members of the Red Hair Pirates who were watching the battle on the coastline were all confused.

"Boss Shanks, what do you think about this kind of thing?" Jesus Bu asked in disbelief.

Shanks narrowed his eyes tightly.

"To be honest, I'm skeptical about this kind of thing."

"This isn't something that can be solved by technology, okay?"

"After all, one person cannot use two devil fruits at the same time. This is an iron rule!"

Shanks said with a serious expression.

Beckman, smoking a cigar, looked towards the battlefield...

"That's right!"

"This isn't something that technology can solve! So... this time, the navy is going to be in trouble!"

"Without a Pirate King-level warrior, it's almost impossible to stop the Red Earl and Barrett's offensive pace!" Beckman said, shaking his head helplessly.

Rayleigh, the Pluto King, who is located on the Sabaody Archipelago, is also skeptical of what Xia Yu said...

"I have been sailing on the sea for so many years, but I have never heard of anyone being able to eat three devil fruits at once, unless they have a special physical constitution!" Pluto Rayleigh said with certainty.

Marinford, on the battlefield...

"Hurry up, Uncle Zhan Guo, if you don't eat, the navy will lose this great war!" Xia Yu urged.

After hearing Xia Yu's words, Zhan Guo's mouth twitched.

"Dr. Xia Yu...is what you said reliable or not..."

"If it's not reliable, I'll be dead!" Zhan Guo smiled bitterly.

I have been in the navy for so many years. If I were afraid of death, I would never have been able to reach the position of Admiral of the Navy...

But the key point is...he died for no reason. For the entire navy, it is definitely an epic disaster!

As a naval marshal, he died without doing anything during the battle between the two armies...

I’m afraid the entire navy will be in chaos by then!

What's even more ironic is that he died from eating a devil fruit...
