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

Beehive Island, the center of this emerging power, has been developing quietly and rapidly over the past six months.

Beneath the surface of calm, two far-reaching events are unfolding simultaneously.

Sea-based railways connect bloodlines

East of the port area, a newly developed coastal construction site is bustling with activity.

The clanging of metal, the hissing of steam, and the shouts of the workers mingled together.

Master Tom, the legendary shipwright of the merfolk, was standing on a makeshift platform.

His iconic massive physique and hearty smile remained unchanged, but his eyes burned with an unprecedented passion.

He waved a huge design blueprint in his hand, giving orders in a loud voice:

"Pay attention to the precision of the track joints! The error cannot exceed three millimeters!"

"Drive those foundation piles another half meter deeper! The waves of the New World are no joke!"

"Is the pressure test for the steam boiler ready? It must be completed today!"

Beside him, Iceberg and Grandma Kokoro were respectively responsible for specific technical supervision and personnel coordination.

After more than six months of preparation, resource allocation, and technical breakthroughs, Master Tom's dream "Sea Train" project has been realized.

Finally, with the full support of the Roy Pirates, the blueprints became a reality.

Roy stood atop a newly built watchtower not far away, overlooking the bustling construction site.

The Sea Train—a miraculous engineering project in the original work that connects the Seven Water Cities with the surrounding islands.

This will now be realized first in his territory.

It is not just a means of transportation, but a network that tightly connects the scattered islands.

"At this rate, the test section from the main island to the trial island will be ready for trial operation next month."

Stella stood beside Roy and pulled up the project progress report.

"Master Tom said that if the test section is successful, he is confident that within a year..."

The initial laying of the rail network connecting the main island to all spheres of influence has been completed.

Roy nodded in satisfaction.

The completion of the sea-crossing railway will greatly compensate for the shortcomings in defense and governance caused by the scattered islands of Beehive Island.

Once the network is established, the efficiency of troop, resource, and personnel mobilization will increase exponentially.

The outer islands will truly integrate with the main island.

"Prioritize ensuring the supply of funds and materials."

Roy instructed,

"Tell Tezzolo that the sea train project is the cornerstone of Beehive Island for the next decade."

All resources were allocated to this task.

At the same time, technical confidentiality measures were taken, with the track laying route and key technical details classified as top secret.

"Understood." Stella wrote down the instructions.

Meanwhile, on a small island next to Beehive Island, which was strictly designated as a military restricted area.

Another, more covert and potentially far-reaching plan is also progressing steadily.

Dr. Gracia's research base has been completely relocated here from Wano Country six months ago.

With the ample resources and relatively stable environment provided by Roy

The doctoral research has made groundbreaking progress.

At this moment, deep within the base, in a highly sterile laboratory filled with sophisticated instruments.

Dr. Gracia, wearing a white lab coat and specially made glasses, was intently staring at several incubation chambers.

Inside the culture chamber, suspended in a pale green nutrient solution, are small, pulsating muscle tissues or organ rudiments with strange textures.

These are derived from Kaido's "Demon Clan" bloodline.

In addition to the "Lunalia" gene sample obtained from Jhin,

And the bear, who also possesses the genes of the special bloodline 'Bakania'.

"Directed enhancement clone embryos" were cultured by combining somatic cells provided by Roy's core members.

"A miracle... truly a miracle of life..."

Dr. Gracia murmured to himself, his fingers gently tracing the outer wall of the culture chamber, his eyes filled with fervent devotion.

"The Oni race's innately powerful physique, and the Lunaria race's legendary 'god-race' bloodline..."

And the immense strength of the Bakania clan.

"The superior genes of these three elite races are selectively screened, enhanced, and have rejection reactions eliminated through 'bloodline factor' technology."

Then, the cells are fused and cultured with the host cells (Roy's core members)...

This will create a 'new bloodline' that combines the advantages of all three and is perfectly compatible with the host!

The doctor's breathing became somewhat rapid.

If this research succeeds, it means that the core members of the Roy Pirates...

You will receive a comprehensive and fundamental strengthening of your physique and enhancement of your potential!

This is no longer a simple "acquisition of ability", but an "optimization" from the very essence of life!

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

Inside Roy's office on Beehive Island.

The afterglow of the setting sun shone through the huge floor-to-ceiling windows, casting a warm golden halo on the smooth tabletop.

Roy sat at the table, holding a thick lab report in his hand, reading it word by word with focused attention.

The report cover bears the emblem of Dr. Gracia's laboratory.

A double helix structure is wrapped around a sword and a test tube.

This is the latest progress report on the "bloodline factor fusion and targeted transplantation" project that he just received from Stella.

The further he turned the pages, the brighter the light in Roy's eyes became.

The report details the work achievements of Dr. Gracia's team over the past six months:

The genetic sequence analysis of the three special bloodlines—"Oni Clan," "Lunalia Clan," and "Bakania Clan"—has been 98.7% completed.

A gene compatibility screening model based on core member somatic cells has been established and validated.

The physiological activity of the directed cultured "fusion embryos" is stable, and the rejection rate is reduced to below 0.3%;

The results showed that the recipient's vital signs were stable after transplantation, potential indicators were significantly improved, and there were no obvious changes in appearance.

Long-term tracking data shows that, through systematic training, the "latent potential" of transplanted bloodlines can be gradually activated to a level approaching that of the original bloodline holder...

The last page of the report contains Dr. Gracia's handwritten summary:

"...After 742 experiments and adjustments, the gene fusion technology for the three special bloodlines has become stable."

Under the current plan, the transplant success rate is estimated at 99.2%, and the potential risks are manageable.

Receptors need to go through an "adaptation period" of three to six months, during which they need to maintain high-intensity training to activate their blood vessel potential.

In theory, once fully activated, the recipient will gain the core physical advantages of the corresponding bloodline race.

Examples include the Oni race's superhuman regenerative abilities and physique, the Lunaria race's surface defense and fire affinity, and the Bakania race's innate immense strength. Furthermore, these advantages will manifest differently depending on the recipient's individual characteristics…

Roy put down the report and let out a long sigh of relief.

The long-suppressed desire in my heart surged up like magma.

Near-perfect bloodline transplantation technology... What does this mean?

This means that his companions, those who have already stood among the strong, will have an opportunity to "upgrade" from the very essence of their lives!

This means their potential ceiling will be raised once again! It means the foundation of Beehive Island's core combat power will be even more solid!

As for himself... Roy's fingers unconsciously traced the edge of the report.

He was certainly tempted.
