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

Dark red lightning danced wildly in the laboratory, but it was not aggressive at all.

This domineering aura wasn't meant to suppress, but rather to convey—

It conveys the unwavering determination to face the unknown and the sense of responsibility that a leader must take the lead.

Barrett's eyes widened. Stimulated by this surge of Conqueror's Haki, his own Conqueror's Haki instinctively tried to resist, but he forcefully suppressed it.

Barrett snorted, crossed his arms, and leaned back against the wall, saying nothing more.

Tesoro lowered his head, golden arcs of electricity dancing silently at his fingertips.

He didn't argue anymore, because he also felt that Roy was right.

If the captain doesn't go first, why should someone else go first?

Crocodile took the cigar from his lips, paused for a moment, then put it back in his mouth and exhaled a smoke ring.

"Whatever you want."

Luo looked at the scene before him without saying a word.

He simply and quietly opened up the surgical space.

A semi-transparent light shield spread out from Luo's palm, enveloping the entire experimental platform area.

Within the ROOM, Luo is the absolute ruler—

He can manipulate any object in the space at will, cutting, rearranging, and replacing it without causing any physical trauma to the person being operated on.

Roy strode into the operating room and lay down on the lab table.

"Let's begin."

Luo nodded, stepped forward, and hovered his hands above Luo's chest.

"ROOM - Organ Replacement"

His fingers twitched slightly.

"The first cloned heart is ready for implantation."

Luo's voice was calm, as if he were stating a fact.

Inside the incubator, a cloned heart, immersed in nutrient solution, floated up and slowly drifted into the surgical space under Luo's guidance.

Under Luo's fingertip control, the heart vanished instantly and reappeared inside Roy's chest cavity.

There were no wounds, and no bleeding.

The heart simply "passed through" the body and landed to the left of Roy's original heart.

The X-rays clearly show Luo's operations on the large screen.

Barrett's eyes nearly popped out of their sockets.

"this--"

"Shut up, don't bother him."

Hawkeye held Barrett's shoulder, his golden eyes fixed intently on the operating room.

Luo's fingers began to dance rapidly.

His movements were so fast they left afterimages, each slight adjustment of his fingers accompanied by a precise connection of blood vessels.

The aorta is paralleled, the pulmonary artery is reconstructed, and the coronary arteries are seamlessly connected to the main circulatory system.

The entire surgery was like a precise symphony in his hands; every movement was fluid and efficient, without a single superfluous action.

Roy closed his eyes and used his Observation Haki to examine himself.

He clearly "saw" Luo's power operating within his chest.

It was an incredibly wonderful experience—

He could feel something growing next to his heart, but the whole process was painless, only a strange sense of fullness.

Ten minutes later, the first heart was fully in place.

"Second cloned heart, ready for implantation."

A fine layer of sweat appeared on Luo's forehead.

But his fingers remained steady, and the second heart floated up under his control, implanted into Roy's chest cavity in the same way, landing on the right side of the original heart.

This time it's even faster.

Having learned from the experience with the first heart, Luo had a complete understanding of Roy's vascular structure, and the connection of the blood vessels to the second heart took less than eight minutes.

"Two cloned hearts are in place."

Luo's voice rose slightly.

"Next, we will reorganize the circulatory system."

This is the most crucial part of the entire surgery—

The three hearts must beat in sync; otherwise, blood flow will be disordered.

"Roy, I need you to actively control your heart rate and coordinate with my recovery movements."

"Tell me what to do," Roy said calmly.

"Three hearts beat alternately in a rhythm of one, two, three, one, two, three."

Your primary heart acts as the main pump, the left side of the heart is responsible for auxiliary circulation, and the right side of the heart acts as a backup pump.

I will guide your vascular system to reconnect; you just need to control your heartbeat in rhythm.

"receive."

Roy took a deep breath, unleashing his full Observation Haki to precisely sense the location and condition of the three hearts.

Then he began to actively control his heartbeat.

Boom, boom, boom.

The three hearts beat alternately in accordance with the rhythm instructed by Luo.

The main heart beats first, followed by the left heart, and then the right heart beats last.

The three pulsating rhythms were distinct yet seamlessly integrated, gradually forming a completely new circulatory system under Luo's vascular remodeling.

Half an hour passed.

The last blood vessel was connected.

Luo abruptly withdrew his hands and shouted, "Done! ROOM, deactivate!"

The moment the surgical space disappeared, a heavy and powerful heartbeat, like a war drum, exploded in the laboratory.

"Thump, thump, thump—"

Three hearts, three beats, converging into a breathtaking rhythm of life.

Roy sat up from the lab table and stretched his shoulders.

Barefoot on the floor, I clenched my fist and felt the blood surging through my body more rapidly than ever before.

My strength has indeed increased.

It's not the kind of dramatic transformation that comes from eating a Devil Fruit, but rather a more fundamental improvement.

Blood flow increases, oxygen supply doubles, and muscle power and endurance both increase significantly.

More importantly, he felt that there were two more "containers" inside his body.

Two containers that can be used to contain the power of Devil Fruits.

"Feels good."

Roy nodded to Roy, his tone casual.

The lab was silent for a moment, and then—it erupted into chaos.

"It's done—it really is done—!!!"

Barrett slammed his hand on the lab table, leaving a deep handprint on the steel surface.

Three hearts!

I just heard three heartbeats!

Not a single sound more, not a single sound less!

"It seems to be quite stable."

Tesoro squinted, golden arcs of electricity dancing wildly in his pupils.

"It's not a short-term stress response; it's a true three-heart synchronized beating."

Boss, how are you feeling right now?

Roy jumped off the lab table and draped his shirt over his shoulders.

"It feels like—I can be even stronger."

He turned to look at Luo, "Who's next?"

Luo wiped the sweat from his face with a towel and reopened the operating room.

"Come on. With the experience from the first time, I can perform the subsequent surgeries much faster."

Half an hour per person, and we'll get everything done today.

Barrett grinned and strode into the operating room.

"I'm the second one!"

Over the next few hours, one by one, the core members of Beehive Island entered Luo's surgical space.

Then, as Luo became more and more familiar with the procedure, one by one, they walked out of Luo's operating space with excited expressions.

And in the end, to everyone's astonishment, Luo also underwent a heart transplant.
