One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

In addition to conventional weapons manufacturing, the core area of ​​the weapons factory also houses a production line for mechanical soldiers.

The mechanical soldiers are modeled after the ancient weapons Roy brought back from the moon.

With the concerted efforts of several scientists, the research team on Beehive Island spent several years deciphering the energy core and drive system of the mechanical soldiers.

Although it is not yet possible to completely replicate all the technologies of the lunar civilization, it has been able to produce mechanical soldiers with performance close to 70% of the original.

These mechanical soldiers are about the same size as ordinary people—

It is about two meters tall, with an alloy shell, and is equipped with an energy cannon and a melee combat system.

The combat power of a single mechanical soldier is roughly equivalent to that of a naval officer who has mastered Armament Haki.

But they don't need to eat, sleep, feel fear, or get tired, and they can be mass-produced.

The first batch of mechanical soldiers is expected to have 3,000 units produced.

When Roy was told this number, even he himself was silent for a few seconds.

Three thousand fearless mechanized combat units, combined with the existing forces on Beehive Island, are enough to crush any resistance force in the New World.

Everything was progressing steadily according to Roy's plan.

Beehive Island is like a precisely operating machine, with each gear spinning at high speed in its own position.

Raw materials were continuously imported from all over the world and processed into weapons, ammunition, and training equipment.

New recruits poured in from various countries and, after training, became qualified soldiers;

The cadres each performed their duties: some were in charge of training, some were in charge of logistics, and some were in charge of intelligence.

Everything is in order.

.................................................. ..................................

Another new day has begun.

The mornings on Beehive Island are no different from other parts of the One Piece world.

The sunlight rolled over from the eastern horizon and shone on the densely packed masts in the harbor.

The new recruits on the training field had already begun their day of physical training. The instructors were yelling and cursing at the top of their lungs on the parade ground. Their shouts mingled with the sound of waves crashing on the shore, and could be heard from halfway across the island.

Roy got up very early.

To be precise, he barely slept all night.

The newly stabilized world order still requires Captain Roy to make many decisions.

Stella and her team of secretaries took advantage of Roy's time on the island to relentlessly send him a backlog of important documents.

When Stella came in to deliver breakfast, she saw Roy rubbing his temples.

A nautical chart of the New World lay before me, covered with a dense array of symbols marked in red and blue ink.

"You didn't sleep all night?"

Stella placed the breakfast on the table and glanced at the nautical chart.

"I slept for two hours."

Roy picked up his coffee and took a sip.

"Dr. Gracia sent another urgent letter last night."

He said his experiment had reached a critical stage and that I absolutely had to go there today.

"The experiment with the black beard?"

"right."

Roy put down his cup and tapped his finger twice on the nautical chart.

"The doctor said that targeted gene culture has been completed, and the live experiments using prisoners have been observed for more than a year."

No genetic breakdown occurred.

Now we'll see if those test subjects can accommodate multiple Devil Fruits like Blackbeard.

This news also silenced Stella.

Blackbeard Teach's physique has always been the mystery that the Beehive Island research team most wants to solve.

How can one person possess the abilities of multiple Devil Fruits at the same time?

According to common knowledge in the world of One Piece, Devil Fruit users will explode and die the moment they eat their second fruit, but Blackbeard broke this ironclad rule.

If Beehive Island could replicate this ability, even partially, what would that mean?

This means that the core members of Beehive Island can possess two or even three Devil Fruit abilities simultaneously.

The improvement of combat power is not addition, but multiplication.

"Let's go."

Roy stood up, rolled up the chart, and put it in the drawer.

"Let's go see what the professor has come up with."

.................................................. ............................

Dr. Gracia's private laboratory is located deep underground on Beehive Island, in a completely isolated building.

The laboratory entrance is located in an inconspicuous gray building, which on the surface looks like just an ordinary warehouse.

But once inside, you have to go through three layers of identity verification—iris scanning, fingerprint recognition, and a combination lock designed by Tezzolo himself.

When Roy walked into the lab, Gracia was hunched over a row of monitor screens.

His eyes were wide open, and he was holding an electronic pen in his hand, the pen tip making a swishing sound as it scribbled across the notebook.

Behind him, in the experimental chamber, a row of culture jars were neatly arranged, each containing a human body.

Those were prisoners captured during the battles fought on Beehive Island, and now they have become the doctor's experimental subjects.

"Doctor." Roy walked up behind him.

Gracia turned his head sharply, his eyes behind his glasses were bloodshot, clearly he had stayed up all night again last night.

"Captain! You've finally arrived!"

I received your message.

Roy placed the box he was carrying on the lab table.

"I've brought all the Devil Fruits you wanted."

The box was opened, and inside were neatly stacked more than a dozen Devil Fruits.

These fruits were all tributes from various countries in the New World. Some were Zoan-type, some were Paramecia-type, and the varieties were incredibly diverse, but they all shared one thing in common—

Roy saw little potential in him, but he thought it was perfect for experimentation.

"Enough! Enough!"

Gracia rubbed his hands together as he walked to the box, picking up each fruit and examining it as if it were a work of art.

Then, he carefully picked out three from them—one Zoan-type Cat-Cat Fruit, Orange Cat Form, one Paramecia-type Color Fruit, and one Paramecia-type Smooth-Smooth Fruit.

"Just these three."

The professor placed the three fruits on the lab table, then waved to his assistant behind him.

"Go and bring over Subject Seven."

The assistant responded and turned to walk into the experimental chamber.

A few minutes later, he pushed out a wheelchair, in which sat a gaunt man.

The man had lost all his hair, and his skin had a sickly grayish-white color.

His eye sockets were deeply sunken, his eyes were devoid of any light, and his whole body seemed like an empty shell.

Roy looked at the man, his brow furrowing slightly: "His mental state..."

"I've been tormented for too long."

Gracia pushed up his glasses, his tone devoid of any sympathy.

"This is the only one among the seventh batch of experimental subjects who survived all the modifications."

After a perfect bloodline transplant, I have also embedded the black beard's gene sequence into his bloodline.

The heart was also modified according to Tichy's physiological structure—

It took a full eleven months to fully heal.

It's already a miracle that they've survived this long.
