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

Barrett was the second member of the Roy Pirates to receive a transplant.

The first thing this battle maniac did after waking up was to rush to the testing grounds.

He exchanged a powerful punch with Kaido, who had also just undergone a transplant and was adapting to his new power!

boom--!!!

At the point where the fists collided, the air exploded, and the shockwave spread in a ring, causing the instruments around the test site to hum.

The two of them each took three steps back, and cracks spread across the ground beneath their feet.

"Hehehe! Barrett, you really didn't disappoint me!"

Kaido grinned and shook his slightly numb arm.

"You too, Kaido! Your strength has increased considerably!"

Barrett's eyes burned with fighting spirit; he could feel the power of that punch.

Its bones and muscles withstood an impact far exceeding that of the past, and recovered extremely quickly.

"Again!"

"Just what I wanted!"

The two violent freaks immediately engaged in a new round of hand-to-hand combat in the test field, their punches landing with tremendous force and the deafening roar of the weapons.

Hawkeye's transplantation process was unusually calm.

After waking up, he silently walked to the training ground, drew his black sword Night, and slowly swung it into the air.

It was a pure slash, without the use of Haki or any special energy.

laugh--!

A nearly invisible pale green slash cut through the air.

The test steel target, suspended in the distance, was silently sliced ​​in half, the cut surface as smooth as a mirror.

"Body coordination, stability, and power transfer efficiency have improved."

Hawkeye sheathed his sword and muttered to himself.

"A sword can be faster, more accurate, and heavier."

Tezoro tested his lightning abilities immediately after the transplant.

He was surprised to find that the output power and fine control capabilities of lightning had been significantly improved.

More importantly, his sustained output time has nearly doubled!

"Now physical fitness is no longer a weakness!"

Tesoro rubbed his hands excitedly, already starting to devise new fighting strategies.

Crocodile, Kuma, Cyrus, Savage, Enel, Pea, Charon, Yamato, and others have also completed their transplants.

Even the female members put aside their work to begin bloodline transplants.

Everyone experienced a comprehensive improvement in their basic physical fitness:

Stronger, more endurance, faster recovery, and more robust defense.

Yamato was especially excited, having fused other optimized traits into her Oni bloodline.

I feel that the speed at which I can condense my frost power has increased.

"If I keep going like this, I'm sure I'll be able to develop even stronger techniques!"

Yamato held Ken's hand, his eyes filled with fighting spirit.

With the core members completing their transplants one after another, Hive Island has entered an era of "evolution" for all its members.

Beehive Island, deep within "Trial Island".

A large circular area was set aside separately.

This is the "Gravity Trial Grounds" that Roy built especially for his companions.

In the center of the field, Roy stood with his eyes closed, his hands lightly touching the ground.

An invisible wave of mental energy spread out from him, enveloping the entire training ground area.

buzz-

The air vibrated with a low tremor, and the light in the arena was slightly distorted.

"Gravity Zone, activated."

Roy spoke slowly.

As soon as the words were spoken, everyone in the room felt a slight tremor.

It felt as if an invisible hand was pressing on my shoulders, and the air seemed to be denser, requiring me to breathe more forcefully.

"Get used to it, then choose a gravity zone that suits you," Roy said.

Inside the arena, Barrett, Hawkeye, Tesoro, Crocodile, Kuma, Cyrus, Savi, Enel, Pea, Charon, Yamato, and others stood scattered, each feeling the changes in their bodies.

Kaido, King, and Queen are also here.

The three leaders of the Beasts Pirates decided to stay on Beehive Island a little longer.

He trained alongside the Roy Pirates, thoroughly familiarizing himself with his newly acquired powers.

"That little bit of gravity is nothing!"

Barrett grinned and stretched his shoulders.

"Roy, let's go all out! This level of gravity isn't even enough for a warm-up!"

"Don't rush, take it one step at a time."

Roy said calmly,

"Everyone has different limits of endurance, and we need to find the most suitable gravity ratio for each person's training."

Roy looked at everyone,

"Now, let's begin basic physical training. Running, push-ups, squats, sword practice..."

Do the movements you're most familiar with, and feel the effects of gravity.

Everyone began training as instructed.

Under the influence of gravity, movements that were originally easy become much more strenuous.

Running requires stronger pushing force with each step, push-ups increase the pressure on the arms, and swinging a sword feels like the weight of the weapon has increased.

But strangely, no one found it unbearable.

The physical enhancement brought about by the optimization of their bloodline allowed them to adapt to the initial discomfort.

It will be able to complete the action at a near-normal speed very quickly.

"As expected, the basics have improved."

Hawkeye swung his sword while making his assessment.

"At the same level of gravity, I feel at least 30% more relaxed now than before the transplant."

"Continue to increase gravity."

Roy observed everyone's condition and slowly began to increase the gravity.

Om-!

Gravity has increased again!

This time, many people's movements were noticeably slower.

Sweat began to seep out, and breathing became heavy.

But everyone's eyes gleamed with excitement.

They could feel that under this pressure, every muscle and every bone in their body was being forged more effectively.

The latent energy is being awakened little by little.

"20 times... I can barely afford it."

Cyrus gritted his teeth and persisted in his sword training, striving for perfection in every strike.

"25 times!" Roy increased again.

Pfft!

Several of the weaker peripheral members were the first to give in, kneeling on one knee and panting heavily.

"You guys exit first and go to the edge area to adapt to 20 times the gravity," Roy instructed.

The members struggled to climb to the edge of the field, where Roy had adjusted the gravity to 20 times, making it relatively easier.

The remaining people in the arena were all core members and strong members of the Beast Pirates.

"30 times!" Roy said mercilessly.

boom!

This time, even young executives like Savi, Enel, and the five-person duo of the Pea CP felt immense pressure.

In his orc form, Savi's muscles bulged and veins stood out.

Enel gritted his teeth and persevered; Pea, on the other hand, had completely entered a semi-beast state, relying on the physique of a mythical beast to tough it out.

"30 times...that's my limit."

Enel gritted his teeth and said that he could no longer maintain normal training and could only stand up with difficulty.

"Me too..." Pea gasped for breath.

"Alright, you guys move to the edge too, and get used to 30 times the gravity." Roy nodded.

The remaining members of the group are: Roy, Barrett, Hawkeye, Tesoro, Crocodile, Kuma, Moria, Kyros, Charon, Yamato, Kaido, King, and Queen.

"40 times!" Roy shouted.

Om-! ! !

The air seemed to freeze.

Under 40 times the gravity, even the air becomes viscous, and every breath feels like swallowing lead.

Moria's expression turned serious, and he silently activated his Devil Fruit power.

It forms a buffer on the skin, but sweat still seeps from the forehead.

Cyrus was swinging his sword extremely slowly, each strike requiring the full strength of his body.

Charon knelt on the ground; the merfolk's physique was not advantageous under such pure gravitational pressure.

Yamato gritted his teeth and persevered, frost faintly forming on his body as he tried to use his abilities to offset some of the pressure.

"40 times...that's almost the limit," Cyrus said with difficulty.

"Me too," the bear nodded.

"Charon, what about you?" Roy asked the merman warrior.

"I... can hold on a little longer..." Charon gritted his teeth, but his body had already begun to tremble.

"Alright, you three step back and get used to 40 times the gravity," Roy said.
