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

Savi and Enel underwent brutal physical and Haki training under Barrett's "hellish" supervision and Roy's gravity field.

Savi's giant ape form is also steadily improving in strength and defense.

Despite his constant complaints, under immense pressure and with Roy's guidance, Enel's Observation Haki range and sensory acuity improved significantly.

Pea, however, remained focused on his little garden.

To cultivate more plants containing life energy, and to attempt to develop plant seeds with aggressive or special auxiliary properties.

For example, thorny vines that can instantly entangle and bind, or flowers that can explode to produce paralyzing pollen.

Roy himself wasn't idle either; he directly pulled the gravity field to the limit that everyone could withstand.

While training everyone, they also familiarized themselves with and consolidated their surging mental strength, and began to try to develop the fruit's abilities more deeply.

At the center of the gravitational field, Roy floated with his eyes closed.

The immense spiritual power spread out like an invisible spider web, meticulously perceiving everything around it, every flow of energy.

He was no longer satisfied with simply manipulating macroscopic objects or altering gravitational sources to apply gravitational fields.

The spiritual energy is explored inward, beginning to 'understand' and 'define' the more essential aspects of the "fruit of thought".

"Nen" refers to one's mental energy, enhanced by the power of a Devil Fruit, taking on a tangible form and using one's thoughts to interfere with the surrounding world.

So, could he directly issue commands to change the rules within the area covered by his mental power?

Without hesitation, Roy locked onto an area in front of him and issued a direct "command" using his mental power.

Instantly, the air in this area seemed to freeze. Roy picked up a pebble and tossed it into the air.

In Roy's observation, the pebbles, which were flying at high speed, suddenly slowed down after entering that area, as if they were stuck in a swamp, and eventually hovered eerily in mid-air!

This scene gave Roy a jolt; it seemed he was on the right track.

Based on his own ideas, he forcibly defined the "state of motion" of this area as almost absolutely still!

This wasn't Roy using his mental power to stop the stone, but rather using his "thoughts" to override the physical rules of that area, forcibly "stipulating" that objects within it were prohibited from moving.

Maintaining this "suspended airspace" consumes a huge amount of mental energy, and the area is extremely small, but the effect is so direct and shocking!

Roy turned his gaze to an ordinary tree branch on the ground.

With a thought, mental energy, like an invisible forging hammer, forcibly infuses the concept of "sharpness" into it.

A cold glint suddenly flashed across the surface of the withered yellow branch.

With a slight thought, the branch shot out and easily pierced through the heavy wooden target in the distance!

He temporarily altered the properties of the substance, giving it the concept of "sharpness" that it shouldn't have had.

Of course, this bestowal was temporary; as his mental energy withdrew, the tree branch quickly returned to its original state.

It even broke apart piece by piece because it was subjected to a "concept" that exceeded its own limits. But this undoubtedly proves the ability of "thought" to interfere with the properties of matter.

The boldest attempt is about to begin.

Roy's gaze locked onto a gust of wind from Barrett's casual punch, and he opened his palm along its path, his mind forming a shield: "Counter!"

An invisible barrier was instantly formed, not a direct confrontation, but a more fundamental distortion of the rules.

The violent fist wind, upon touching the barrier, was as if it had struck an absolutely smooth and impenetrable mirror. Its direction of travel was forcibly reversed, and it blasted back towards Barrett himself with undiminished power!

A flicker of surprise crossed Barrett's eyes as he deflected the returning force of the punch with a single blow. Roy, on the other hand, paled and swayed slightly.

The backlash from forcibly changing the rules was far greater than ever before; the force of Barrett's punch almost drained half of his mental energy.

This also made Roy clearly realize that this ability to "make words come true" seemed omnipotent, but in reality, it had great limitations.

Forcibly distorting the core rules can easily cause a backlash of power, harming oneself.

However, its potential is undeniable.

In a crucial moment, a single phrase like "Here, domineering power is ineffective" (if it can be done) or "This strike will surely hit" is enough to instantly turn the tide of battle!

Roy landed slowly, took a deep breath, and calmed his turbulent mental energy. His eyes were filled with anticipation for this power.

These attempts were extremely limited in scope and consumed enormous resources, but they clearly showed Roy the direction for the next stage of fruit development—'distorting reality with thoughts,' allowing his 'ideas' to directly define the rules.

After several days of intense training and skill exploration, Roy decided to slow down for the time being.

Overdrawing his mental energy is not a wise move; he needs to reflect on and digest his recent gains.

Night came,

The campfire crackled in the center of the camp, illuminating the tired but satisfied faces of the group.

Peas, combined with newly cultivated "full-boosting mushrooms" and grilled fish, surprisingly created a fragrant dinner that can quickly restore energy.

Just as Roy took a bite of the pea-flavored "full-feeding mushroom," the Den Den Mushi in his arms suddenly rang urgently.

"Brubrubrubru... Brubrubrubru..."

The unusual ringtone stopped everyone in their tracks, and all eyes turned to Roy—it was a dedicated Den Den Mushi for emergency communication with Tom's Studio.

Roy quickly took out his Den Den Mushi and pressed the answer button: "Hello, Mr. Tom?"

"Roy, things aren't looking good."

"Several new groups of unfamiliar faces have arrived in Water Seven today. Although they are disguised as merchants and tourists, I can tell at a glance that they are CP agents. There are also two disguised naval warships docked at the pier."

"It seems the World Government has already suspected this place."

Roy's face instantly darkened.

Roy pondered for a moment, then calmly replied to the Den Den Mushi:

"Mr. Tom, please continue with normal construction and do not show any abnormalities. We will handle things here and will not allow the Navy to interfere with the shipbuilding progress."

"Hahaha! You real men! Then it's up to you!"

"I will speed things up and get the new ship launched as soon as possible!"

After hanging up the phone, Roy glanced around at his friends.

"Everyone heard it."

"The Navy and CP have extended their reach to Water 7. The construction of the new ship is at a critical stage, and there can be no mistakes."

"However, if we all return to Water Seven now, we'll be too conspicuous and it could easily trigger a conflict, which would expose Mr. Tom."

Roy nodded.

"Stella's concerns are not unfounded, so we shouldn't go back. The best thing to do now is to create some trouble for the Navy and divert their attention from Water Seven."

Roy stood up, a cold smile curving his lips, the campfire casting a long shadow of him.

"I've decided to 'visit' several important naval bases along the Grand Line."

"Since they have so much free time and energy searching for us, let's give them something worthwhile to do!"
