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

On the battlefield of Marineford, the balance of war is gradually tilting in favor of the navy.

The battle between Whitebeard and Akainu has entered its most intense phase.

Each tremor and collision with the lava made the entire island shudder, and the ice surface was covered with huge cracks left by the two and black rocks formed from the cooled lava.

The wound on Whitebeard's chest had completely reopened; the injury inflicted by Squard's sword was being torn apart again during the fierce battle.

Blood flowed down his abdomen, pooling into a small dark red puddle on the ice.

"Gurararara—You little magma brat, your punches are getting lighter and lighter! How come you can't even handle an old man like me anymore!"

Whitebeard cleaved Akainu's magma fist in two with a single slash, the Tremor-Tremor Fruit's power sending magma flying everywhere.

Akainu was knocked back several steps, and a trace of blood spilled from the corner of his mouth, but the fighting spirit in his eyes did not diminish in the slightest.

"Old man, how much longer can you hold on?"

Akainu's right arm turned into magma again, with an even higher temperature than before, and the color of the magma changed from dark red to a dazzling bright white.

He could see that the white-bearded man's breathing was getting heavier and heavier, and there would be a very brief pause after each swing of his knife—a sign of exhaustion.

But just as the two were about to collide again, a roar came from the other side of the battlefield.

"Ace—run!"

It was Marco's voice.

Akainu's gaze passed over Whitebeard and looked into the depths of the harbor.

There, Luffy and Ace were desperately trying to break through the encirclement, with Moria's shadow bats, Hancock's petrifying arrows, and Jinbe's fish-man karate forming an impenetrable defensive line around them.

But this defensive line is being compressed layer by layer by the navy.

Standing on the ruins, the Warring States period commander personally directed the encirclement and annihilation.

"First formation, advance! Second formation, block the left flank! Third formation, seal off the port direction!"

The naval soldiers surged forward like a white tide. One squadron was broken up, and two more squadrons immediately took its place.

Those who fell were dragged to the back, and new soldiers continued to rush forward, stepping over the bloodstains of their comrades.

Luffy's breathing became more and more rapid.

He's been in second gear for too long, and his body is nearing its limit.

Each time the rubber machine gun fired, the fist moved a fraction slower than the last time.

"Luffy! You're injured!" Ace looked at the bruises on Luffy's back caused by the blow from the Great Buddha of Sengoku, his eyes filled with heartache.

"fine!"

Luffy grinned, but the blood at the corner of his mouth betrayed him.

"I can still fight!"

Moria's shadow bats blocked another round of artillery fire, but the shadow beneath his feet was noticeably fainter than before.

"Hey, Straw Hat Boy, now's not the time for reminiscing!"

Jinbe delivered a powerful punch with 5,000 tiles, sending a rear admiral flying. However, two vice admirals immediately rushed in to fill the gap.

Although his Fishman Karate is powerful, it consumes a lot of energy when facing such a large number of people.

Hancock's situation isn't much better.

Her petrification ability is an instant kill for regular soldiers, but against lieutenant generals with solid Armament Haki, the petrification arrows can only serve as a restraint.

Her physical strength was also rapidly depleting.

"There are too many navy men!" Hancock gritted her teeth and kicked three more soldiers away with a fragrant kick.

Meanwhile, outside the encirclement, the captains of the Whitebeard Pirates were also frantically attacking the Navy's defenses.

Vista wielded his twin blades wildly, the trajectory of the foils cutting gaps through the naval formation.

Joz's body turned half of its body into diamond, and he used his shoulder to withstand the artillery fire as he rammed forward.

The other team leaders also gave it their all, and each of them ended up with bruises.

Zefa stood in the center of the defensive line, arms crossed, his short purple hair motionless in the sea breeze.

Several captains of the Whitebeard Pirates were lying haphazardly at his feet.

"Want to get over here? You'll have to step over my dead body first!"

Zephyr unleashed his Black Arm Armor with a sudden burst of power, his fist enveloped in Armament Haki, sending the leading Prundi flying.

The situation on the battlefield is becoming increasingly unfavorable for the pirates.

Whitebeard was held back by Akainu, Marco was trying to restrain Kizaru in the air but was clearly at a disadvantage, the captains were being held back by Zephyr, and Luffy and Ace were surrounded.

Standing on high ground, watching all this, Zhan Guo felt a strange unease welling up inside him.

The battle situation was clearly developing in a direction favorable to the navy.

Whitebeard's stamina is waning, and defeat is only a matter of time. Luffy and Ace's escape route is shrinking, and the captains' offensive is weakening.

But the unease grew stronger and stronger, like a needle stuck in the back of his head that he couldn't pull out.

He subconsciously looked up at the sky.

There were only clouds in the sky.

Thick clouds have been gathering since just now, like a sign of an approaching storm.

But today's weather forecast clearly stated that the waters near Marineford would be sunny.

Not right.

The pupils of the Warring States period contracted slightly.

His Observation Haki instinctively extended upwards, piercing through the clouds, attempting to perceive what lay above them—

Then his Observation Haki collided with an invisible barrier.

"Could it be...?"

Just as Sengoku realized something was wrong, the sky over Marineford suddenly darkened.

Everyone looked up at the same time.

The clouds overhead began to thicken and darken at a visible rate.

The once pristine white cumulus clouds darkened rapidly, as if stained with ink, and the cloud cover continued to expand.

Extending from one side of the harbor to the other, it casts a somber shadow over the entire Marine Fondo square.

"What is that?"

"Are the clouds turning dark?"

"What's going on?!"

The naval soldiers whispered among themselves, and some began to nervously grip their weapons.

The veterans and officers who had seen more battles looked grave—this strange weather change was definitely not a natural phenomenon.

Lightning flashes could be seen flickering in the clouds.

At first, only a few thin arcs of electricity flashed across the edge of the clouds, but in an instant, those arcs turned into thick lightning bolts, surging and weaving through the clouds.

The rumbling thunder came from deep within the clouds, growing louder and more intense, as if a giant beast was awakening in the clouds.

Then, a crack appeared in the clouds, and the crack grew wider and wider, revealing the view above the clouds—

A ship.

A colossal ship, its entire body crackling with golden lightning, hovered above the clouds.

Dense golden arcs of electricity danced around the ship's hull, merging with the lightning in the clouds, making the ship itself seem like the core of the thundercloud.

"That's—!!!"

Everyone on the battlefield instinctively gasped.

There was a person standing at the bow of that ship.

He wore a black trench coat, with the Black Sword Autumn Water hanging at his waist, and the sea breeze ruffled the stray hairs on his forehead.

He stood at the bow of the ship, his hands in his pockets, looking down at the battlefield strewn with corpses with a cold, indifferent gaze, as if looking down at ants.

Emperor of Heaven, Roy.
