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

Luffy carried the golden key and walked to the first chain.

The key made a crisp "click" sound as it was inserted into the lock, echoing deep within the underworld.

"Splash~"

The chains fell to the ground.

It was a very heavy sound, like an entire stone pillar crashing to the ground, making the pebbles beneath our feet jump.

Loki's fingers twitched again, visibly curling up as if grasping something and then letting go.

Then, Luffy continued.

Article .

Article 3.

With each chain unlocked, a subtle change would occur to Loki.

It wasn't the kind of change that could be immediately seen with the naked eye, but rather a change in aura.

A very faint aura seeped from his body, like something that had been dormant for a long time slowly awakening.

By the fifth time, Nami had retreated more than ten meters away.

Her face was deathly pale, and her legs were trembling slightly.

She didn't know why she was so scared, even though Loki was still looking down and he looked like he was having trouble breathing.

But his aura was terrifying.

The feeling was like something—like an ancient, ferocious beast gradually reviving.

Zoro also placed his hand on the hilt of his sword.

He narrowed his eyes, watching Loki's every move warily.

Just as Luffy was about to untie the last chain binding Loki's feet.

"Boom boom boom~"

The ground in the distance suddenly began to shake violently.

The sound of several giants running down from above pressed down like a drum pounding on everyone's head.

Haildin was the first to rush down.

He jumped onto the ground of the underworld, creating a huge crater, and rubble exploded in all directions.

His hair was disheveled, his face was covered in dust, and his eyes were bloodshot, making him look like a demon crawling out of hell.

He saw the key in Luffy's hand at first glance.

Then his gaze swept over Loki—the few chains on Loki's body that had been untied, and the seastone chains lying on the ground, curled up like dead snakes.

"stop--!!!"

Haildin's roar caused rocks to fall from the cave ceiling with a loud crash.

Luffy stopped what he was doing and turned to look at Hajrudin.

Zoro and Nami also turned around.

One by one, members of the New Giant Warrior Pirates rushed out of the darkness and surrounded Luffy and his crew.

Some of them landed on the ground, while others were still crouching on the rock face, their weapons all drawn and aimed at Luffy and Loki.

Haildin stepped forward, his chest heaving violently, his voice urgent and angry:

Do you know what you're doing?!

Releasing Loki will bring disaster to the entire Elbaf region!

"Huh? Is that so!?"

Luffy looked at Hajrudin and scratched his head.

Just then, a very low laugh came from behind him.

The laughter was intermittent, like a broken bellows leaking air, but the moment they heard it, all the giants froze in their tracks.

Halding's pupils shrank to pinpoints.

Luffy slowly turned his head.

Loki had already sat up at some point.

He leaned against the tree trunk, his head bowed, his messy purple hair obscuring half his face.

But everyone could see that a slight smile was playing on his part.

Beneath the bandages, eerie golden vertical pupils gleamed through his hair, half-open and half-closed, carrying an indescribable meaning, staring directly at Halding.

"Hahahaha!"

The surrounding air froze completely.

The moment Hajrudin met Loki's gaze, the hairs on his body stood on end.

He was all too familiar with that feeling. From childhood to adulthood, every time Loki looked at him with those eyes, nothing good ever came of it.

"Stop him! Don't let him stand up!" Haildin roared hoarsely.

The giants of the New Giant Warrior Pirates snapped out of their daze and swarmed forward.

They coordinated perfectly, flanking from all directions, the wind pressure generated by the massive weapons whipping up rubble from the ground.

But as soon as they took a step, Loki stood up.

Indeed, the chain on his feet restricted his range of movement; he could only stand a few steps away from the tree.

But the moment he stood up, it was as if all the air in the entire underworld had been sucked out.

Loki, who possesses the blood of the ancient giants, is several times taller than Hajrudin and others.

A fierce aura erupted from his body.

All the giants moved a beat slower, as if some invisible force was holding their bodies down.

Loki did not look at the giants.

He didn't even look at Halding.

He turned around and reached his hand toward the enormous, boundless Adam Tree behind him.

There is a protrusion on the trunk covered by a burl, which looks integrated with the tree body, like a naturally grown deformed lump.

Loki's fingers touched the burl and he yanked it off sharply.

The sound of tree bark cracking echoed through the underworld.

When the giants saw the warhammer Loki pulled from the tree trunk, every face turned pale.

A massive, jet-black warhammer, its head as large as a house, crackling with lightning.

"Iron Thunder!"

Halding's voice was forced out through clenched teeth, trembling uncontrollably.

"So that thing was always here..."

Loki, gripping the Iron Mine, glanced down at Hajrudin, his tone dripping with mockery:

"Of course it's here."

Lightning spread from Loki's arm to his entire body, enveloping his figure in a blinding dark red electric light.

He easily swung the iron thunderbolt, spinning it overhead, the resulting wind pressure tearing the surrounding ground apart.

"Don't let him swing the hammer!" Haildin roared until his voice was hoarse.

But no one could step forward.

Loki's aura had expanded to a terrifying degree. Even without Conqueror's Haki, his sheer pressure made the legs of all the giants present feel like they were filled with lead, and they couldn't even lift them.

Loki didn't hit anyone.

He turned around, lifted the iron thunderbolt high, and slammed it down hard on the Adam Tree behind him.

"Stop—!" Halding lunged forward.

late.

The hammer struck the tree trunk.

What exploded wasn't wood chips, it was lightning.

Dark red lightning poured from the iron thunder into the tree trunk, like a released thunder dragon, and climbed wildly upwards along the fibers of the Adam Tree.

The ground of the underworld was shaking, and the entire giant tree was emitting a teeth-grinding roar, as if something ancient and enormous was being torn apart from the inside.

The bark exploded off the surface of the trunk, and wood chips, crackling with lightning, flew in all directions.

A piece of bark the size of a house hit the ground, bounced up, and rolled a long distance, knocking a giant who couldn't dodge it away.

The thunder dragon pierced through the tree trunk, rushing from the roots to the crown, and then soaring into the sky from the top of the crown.

Those in the upper realm only saw a blood-red pillar of lightning erupt from the giant tree Adam, splitting the entire sky in two.

At that moment, everyone in Elbaf looked up at the sky, and whatever they had been doing before stopped.

After the lightning bolts disappeared, plumes of thick smoke billowed out from the cracks in the tree trunk.

Flames erupted from inside the giant tree, crackling and spreading outwards at an utterly irrational speed.

The fire, accompanied by black and red lightning, exploded wherever it burned, and flames instantly raged throughout Elbaf.
