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

23,700 units.

"More than 20,000, each one is no worse than the one outside."

Jin was silent for a few seconds: "Twenty thousand colonel-level officers working together... another Yonko group."

"more than."

Roy walked towards the nearest mech and used his telekinesis to probe its internal structure.

"The outer shell of this thing is harder than seastone, and its energy weapon is at least ten times more powerful than a standard naval cannon."

"Twenty thousand joined forces..."

Roy didn't finish his sentence, but his meaning was clear.

If the world government knew that something like this was hidden on the moon, it probably wouldn't be able to sleep soundly.

Scientists quickly poured in. The moment they saw the mechanical warriors, their eyes lit up—the kind of eyes that look like wolves that haven't eaten for three days seeing meat.

"This core energy source..."

Gracia's assistant—a young researcher—was lying on the chest of a robotic warrior, gesturing back and forth with a scanner.

"Its flame wavelength is exactly the same as that of the Lunaria race!"

"The outer shell is made of an unknown alloy!"

Another researcher tapped the mechanical warrior's arm.

"It's harder than seastone, but much lighter!"

"Weapon system..."

A female researcher carefully pried open the mechanical warrior's hand, revealing the energy cannon inside.

"In terms of precision and structure, we are at least fifty years behind!"

Yamato and the others excitedly surrounded a mechanical warrior, banging and tapping on it, their admiration growing with each look: "Roy! If only we could bring these big guys back to Beehive Island..."

"With these, fighting the navy will be a piece of cake!" Savi chimed in.

Enel went even further: "Could you take one apart so I can study it?"

Pea stared at the mechanical warrior in front of her and asked curiously, "Will they listen to us?"

Just as Roy was about to answer, he heard a "click".

Yamato's hand touched the blue core on the mechanical warrior's chest.

The core flickered.

The blue light started from that machine and spread to the surrounding area.

One, ten, one hundred, one thousand—the mechanical warriors across the entire square lit up one after another, like dominoes.

"Invaded life form detected..."

Mechanical voices came from all directions, cold and orderly, like an army making a unified announcement.

"Unregistered race..."

"Start the cleanup process!"

All the mechanical warriors' eyes lit up red simultaneously.

The formation began to move. The arms of the mechanical warriors in the front row deformed, revealing dark, gaping cannon muzzles.

The mechanical warriors in the back row drew their lightsabers from their waists, the energy blades humming in the darkness.

Twenty-three thousand seven hundred mechanical warriors completely surrounded Roy and his companions.

"Fire!"

A volley of shots.

Thousands of energy projectiles came from all directions, as dense as a torrential rain.

Roy immediately expanded his psychic field to its fullest extent, forming a hemispherical shield. The energy blast struck the shield, creating ripples.

"Don't act impulsively!"

Roy stopped the others from retaliating.

"Let me check their combat strength first."

Each energy blast is as powerful as a full-force attack from a rear admiral.

Roy's shield could block it, but each impact drained his psychic energy.

As the scientists said, the outer shell's defensive capabilities are indeed as strong as they appear; ordinary slashes simply cannot cut through it.

Barrett punched a mechanical warrior in the chest, only knocking it back a few steps, without leaving a dent on its shell.

The joints are a weak point. Hawkeye slashed at the mechanical warrior's elbow, and the arm snapped off instantly.

Their coordination was terrifyingly perfect. Front-line firing, rear-line charging, flanking maneuvers, rear support—the formation was impeccable, their advances and retreats measured, more disciplined than any human army.

Roy quickly assessed that each mechanical warrior possessed the combat strength of a naval officer at the rank of colonel, and 20,000 of them working together would be enough to wipe out the lower ranks of a Yonko crew.

But just as Roy was about to order a full-scale counterattack, he noticed something.

All the mechanical warriors' attacks avoided the spot where Jhin was standing.

It doesn't seem like a coincidence.

Roy carefully observed several volleys and confirmed this.

There is always a safe zone with a radius of three meters around Jin.

No energy blasts flew toward him, no lightsabers slashed at him, and even charging mechanical warriors would avoid him.

"Jhin," Roy called out, "Try taking a few steps forward."

Jin did as instructed.

The mechanical warrior's attack direction adjusts as he moves.

Wherever he goes, that place is safe.

"Stop!" Roy shouted again.

Jin stopped. The mechanical warriors around him ceased their attack, the red light in their eyes returned to blue, and some even bowed slightly, as if in salute.

"They know you," Roy said. "Or rather, they know your bloodline."

Jin took a deep breath: "I can feel... they're waiting for me to go somewhere."

"where?"

Jin pointed to the end of the plaza. There, an even larger metal door was embedded in the wall, engraved with the same Lunaria totem as the one at the entrance to the stone temple.

"Let's go," Roy said, "let's go take a look."

Protected by Roy's energy shield, the group passed through the mechanical array.

The mechanical warriors automatically made way for them.

Soon a metal door appeared before them, smaller than the entrance to the stone hall, but still several tens of meters high. Without hesitation, Jin placed his palm on the door.

A golden light swept across.

The metal door slowly opened.

Behind the door is a huge circular hall, 500 meters in diameter, with a towering dome.

The walls were covered with screens and control consoles. The screens were still black, but the indicator lights on the control consoles were flashing, indicating that the system was still running.

In the center of the hall, a huge blue sphere of light floated.

It is at least thirty meters in diameter, radiates pulsating blue light, and possesses astonishing energy.

Countless optical cables extend from the optical sphere, connecting to the surrounding equipment, like the root system of an upside-down tree.

"This is the central hub," Roy murmured.

The moment Ember stepped closer to the orb of light, the blue light turned gold.

"Lunalia's bloodline confirmed..."

Mechanical voices came from all directions, gentler than those of the mechanical warriors outside.

"Priority level... highest."

The screen lit up one after another.

Holographic images were projected around the sphere of light—a map of the mechanical legion's distribution, a structural diagram of the moon's interior, a route map of energy flow... a dense array of data pulsed around.

Jhin reached out and pressed his hand against the energy projection on the surface of the light sphere.

"Stop attacking." His voice wasn't loud, but the system understood.

"Command confirmed. Mechanical Legion enters standby mode."

In the square, the 23,700 mechanical warriors simultaneously extinguished their blue lights.

As the crisis subsided and everyone rushed into the hall, they were all awestruck by the enormous blue sphere of light in the center.

The scientists, disregarding everything else, rushed to the control panel and began operating it.

The data on the screen was jumping rapidly, and the holographic images were constantly switching, making the entire hall seem to come alive.

Olvia sat at the main control console, staring at the ancient text, her fingers flying across the virtual keyboard. Her eyes grew brighter, her breathing more rapid.

"Captain... there's so much information here."

"Pull it up and take your time to look at it."
