One Piece: The Navy's Eight-Year-Old Tech Prodigy, the Four Emperors Have Gone Mad

"Hahaha! A Shichibukai-level Seraphim now costs only twice as much as Dr. Xia Yu's Seraphim after I've perfected it over and over again!"

"I guess it won't be long before I can catch up with Dr. Xia Yu!" Vegapunk was very excited.

I also plan to relax.

"After such a long and boring study, my brain needs some rest!"

"Right now, I'm afraid the battle between the navy and Whitebeard has already begun."

"That's perfect. Let me appreciate this great war!"

Vegapunk said this with a happy look on his face.

Then, under the assistant's arrangement, the big screen was turned on directly.

Then, we saw the classic scene of Zhan Guo defeating Zhan Guo with three punches...!

"What? In this world, let alone man-made ones, even real devil fruits can't be this terrifying, right?"

"Just relying on a devil fruit, he was able to directly upgrade Zhan Guo to the King level!"

"This is simply... incredible!"

Vegapunk said this in an extremely exaggerated manner.

As for the devil fruit, Vegapunk has naturally also studied it!

However, the devil fruit he developed only possessed some of the abilities of the Emperor level...

Moreover, the consumers themselves have to continue developing it!

How could it be as terrifying as Xia Yu’s research?

Just by eating the devil fruit, the fighting power that erupted was enough to elevate Sengoku to the king level!

This devil fruit is hard to find even in the real world...

An absolute god-level fruit!

"I originally thought that the gap between me and Dr. Xia Yu should be getting smaller and smaller..."

"Who would have thought that the gap between me and Dr. Xia Yu would be so huge now?" Vegapunk opened his mouth wide, looking extremely shocked.

Before, I always thought that Xia Yu was just gifted in machine manufacturing...

But now it seems that not only in the field of Seraph, but also in the field of space, mecha manufacturing, and even devil fruits, Dr. Xia Yu has surpassed himself by a large margin!

On the battlefield, after defeating Barrett with one blow, Zhan Guo's eyes turned to Whitebeard, who was now unstoppable...

"Whitebeard! I absolutely cannot let you get Dr. Xia Yu!"

"Dr. Xia Yu, you are a hero of our navy!"

Zhan Guo, the whole person roared.

Then, he took out the long sword at his waist and slashed at Whitebeard!

Hum...!

A huge yellow slashing wave suddenly appeared in the sky.

Then he hit Whitebeard hard...!

Whoosh...!

A yellow slashing wave, covering the sky and the sun, rushed towards Whitebeard with an attitude of destroying everything!

Under the powerful force, the ground below the huge yellow slashing wave was affected by the remaining waves, and pieces of the ground cracked directly.

The slashing wave, like thunder, instantly hit the ground of Marinford!

boom...!

Under the powerful force, the entire Marinford shook, and the sea at the coastline also churned.

At this time, the Dreyfussah, where Red-Haired Shanks was located at the coastline, was also churning along with the sea.

Shanks and the others on the hull held on tightly one by one.

The corners of Beckman's mouth twitched.

"Just a random slash, but it actually affected us, who are deep on the coastline?"

"This power is too strong!" Beckman said in shock.

Then, Lakilu, who was on the hull, widened his eyes.

"No, look quickly... look quickly!"

Lakilu, the big elbow in his hand, slipped directly to the ground. He widened his eyes and looked exaggerated.

? ?

Shanks and the others looked in the direction that Lakilu pointed.

Afterwards, everyone on the ship was completely dumbfounded.

On the battlefield...

Along with Zhan Guo's devastating blow, the entire earth collapsed and pieces of soil flew directly into the air.

The entire land of Marinford was cut in half by Zhan Guo's attack!

The terrifying cracks spread directly into the depths of the sea below...

A large amount of sea water began to flow directly from underground towards Marinford!

It was like a huge fountain, gushing towards the people of Marinford!

"How is it possible?! Marshal Zhan Guo cut Marinford in half with just one strike!"

"We're done for! Marshal Zhan Guo's terrifying slash actually pierced through the seabed. This sea will swallow us up!"

The sailors on the land of Marinford all showed expressions of horror.

At this time, the Seraph Aokiji in the sky released a white flame directly towards the sea in the sky, and then the entire sea was completely frozen by this strange flame!

"Fortunately, we have Dr. Xia Yu's Seraph."

"We are saved!"

The sailors were frightened.

At this time, the three generals saw the current scene and their faces changed drastically.

Sakaski, as a whole, opened his mouth wide.

"I thought my magma fruit was terrifying enough!"

"I never thought that the artificial devil fruit Xia Yu researched would be a hundred times more destructive than my magma fruit!"

Chapter 145 Whitebeard joins the battlefield and fights Susanoo

Aokiji Kuzan, seeing the terrifying fighting power displayed by Sengoku, widened his eyes and was amazed...

"It's really enviable, such terrifying combat power. If Dr. Xia Yu could give me such a god-level devil fruit, that would be great..."

Aokiji Kuzan said with jealousy.

The sailors cheered even more!

"Dr. Xia Yu! You are our savior!"

"Hahaha! With Marshal Sengoku, who has such terrifying combat power, even if we face three of the Four Emperors and all the criminals in the Undersea Prison at once, what can we do?"

"Dr. Xia Yu is truly terrifying. Not only did he create so many Seraphs for our navy, he also created universal capsules and steel mechas.

Now, he has even created a god-level artificial devil fruit... Dr. Xia Yu, one person is completely worth thousands of troops! "

"It's time for this farce to end!"

The entire navy in front of Marinford cheered, and at this time... they had completely regarded Xia Yu as the new hero of the navy!

At this time, the Whitebeard Pirates' captains, Marco, Jozu, Whitebeard and others, who had already left, watched the battle on the battlefield, feeling anxious...

"Damn it! Dad, you went there to capture Xia Yu for us!"

"Such a terrifying slash has had a huge impact even though we are now on the edge of the coastline of Marinford. I wonder if Dad will be in trouble?" Joz said nervously, clenching his fists tightly.

Fire Fist Ace gritted his teeth tightly, with a look of regret on his face...

"Damn it! Dad, you finally rescued me, and now you're taking risks again, and I'm powerless to do anything. I'm such a failure!"

Vista patted Ace's shoulder.

"Ace... no one can predict things like this."

"It's mainly because of that kid Xia Yu. His technology is really too powerful..."

"It's even so powerful that it's unbelievable!"

"I'm afraid that before Zhan Guo showed the powerful power of his devil fruit, no one in the world could have imagined that Xia Yu...that eight-year-old kid, had actually developed a god-level devil fruit!" Vista said depressedly.

If they had known that Xia Yu's technology was so powerful, they would never have let their father take such a risk...

But now...it's too late to say anything!

On the battlefield...

As the smoke that had stirred up the entire Marinford receded, Whitebeard's figure gradually emerged before the crowd...

At this time, Barrett, who had fallen to the ground before, also stood up...

The two of them looked at each other directly, and from each other's eyes, they could see a deep fear of the current Warring States period!

Pfft...

The next moment, both of them spat out large amounts of blood from their mouths...

"Whitebeard, if you don't kill Zhan Guo, I'm afraid you won't be able to get close to Xia Yu!"

"How about... we take down the Warring States together!"

Even Barrett, who always likes to be alone, was surprised to propose cooperation with Whitebeard...

no way!

The fighting power displayed by the Warring States Period is really terrifying!

Even surpassing the original Pirate King Roger!

Faced with an opponent more terrifying than Roger, Barrett has no choice but to seek cooperation!

Whitebeard, who has always been proud, also has a solemn expression on his face.

Xia Yu, now just one of his many inventions, has directly cultivated a Pirate King-level warrior for the navy...

If Xia Yu were allowed to continue inventing...

In the later stages, I wonder how many more king-level warriors can be cultivated!

In this case, even the white-bearded man in my own world is not good enough...

Just think about it... In the future world, with the Seven Warlords of the Sea and the Emperors running around everywhere, Whitebeard felt a burst of fear when hearing the terrifying broadcast!

The Whitebeard Pirates must get Dr. Xia Yu, this kind of genius!

Otherwise, in the future, even if you want to live in peace in a corner, it will be impossible...!

"Okay! But, Barrett, you mustn't attract Dr. Xia Yu's attention!"

"Dr. Xia Yu is mine!"

Whitebeard roared.

"Don't worry, Newgate. You know, what I've always longed for is my own strength. As for technology, I'm not interested!"

Barrett said with a grin.

I didn't listen, but that's not what I thought in my heart!

Even when an admiral-level Seraphim attacks, Barrett's belief has always been that he will become the strongest!

However, when Zhan Guo took three punches from Zhan Guo, he was beaten to the ground, unable to get up, and spitting blood...

Barrett's entire worldview completely collapsed at that moment...
