The biting frost of the research facility was not confined to the outdoors. Roronoa Zoro wandered aimlessly through the sprawling, labyrinthine corridors, his hand resting casually on the hilt of Shusui. He had intended to follow Luffy, but after taking a wrong turn at a three-way junction, he had somehow ended up in a massive, vaulted chamber.

The air in this room was freezing. Thick, heavy snow drifted down from the high, dark ceiling, blanketing the metallic floorboards in a pristine layer of white. It was a bizarre, indoor blizzard, lit only by the eerie, pulsing blue glow of massive coolant vats lining the walls.

Zoro stopped, exhaling a long plume of mist. He looked around, completely unimpressed. "Great. I followed the idiot, and now I'm in a freezer. He probably found some meat and left forgot about Ceaser."

Before he could take another step, the wind in the chamber howled, shifting violently.

From the swirling snow above, a shadow descended with silent, lethal grace. Monet plummeted from the whiteout, her large, feathered wings tucked tightly against her sides as her sharp talons reached out, aiming directly for the back of Zoro's neck.

Zoro didn't even turn around.

His eyes narrowed as his Observation Haki instantly registered her trajectory. With a seamless, fluid motion, Zoro stepped slightly to the side. The razor-sharp talons grazed the air mere inches from his shoulder, cutting nothing but the empty wind.

Monet landed softly in the snow, her cold, calculating eyes locking onto the swordsman as her wings spread wide, kicking up a small flurry.

"You have quick reflexes, Roronoa Zoro," Monet mused, her voice carrying a chilling, melodic quality that echoed in the vaulted space. "But you are a long way from home. This room is my domain."

"A bird-woman," Zoro grunted, his hand still resting on his sword. "You're the one Usopp was babbling about. Out of my way. I'm looking for my captain."

"I'm afraid I can't let you leave," Monet smiled, her form suddenly beginning to dissolve into pure, sparkling snow. "Yuki Yuki no Mi: Blizzard Wall!"

The snow on the ground violently erupted, rising like a wave to form a towering, solid barricade of ice and packed powder, trapping Zoro within a confined circle. The temperature plummeted further, the air growing so cold it threatened to freeze the very blood in his veins.

Monet materialized from the blizzard wall directly behind him, her wings transforming into sharp, icy blades. She launched a flurry of flying snow slashes, aiming to shred his flesh and freeze him solid.

Zoro didn't even draw his blades. He simply shifted his stance, his body swaying with effortless precision to avoid every incoming strike. The icy slashes embedded themselves into the metal floorboards, shattering into harmless frost.

"Is this the best you can do?" Zoro asked, his tone flat. "The snow is annoying. I don't have time to play with you."

Monet's eyes flared with anger. She dissolved again, merging entirely with the blizzard, her voice echoing from all directions. "Snow Fang!"

A massive, multi-headed dragon crafted entirely from solid, compacted ice and snow erupted from the drifts, its jaws snapping down toward Zoro's head.

Zoro finally reached for Sandai Kitetsu. He drew the cursed blade, the polished steel catching the blue light of the coolant vats.

With a single, rapid horizontal sweep of his arm, Zoro unleashed a localized, flying wind slash. The sheer, crushing pressure of the wind pressure alone was enough to rip the air apart. The spatial force of the strike hit the ice dragon head-on, completely obliterating the beast into a harmless cloud of fine powder.

But the slash didn't stop there. The wave of compressed air traveled forward, violently parting the blizzard wall and striking Monet's snowy form.

A sharp gasp echoed as Monet was forced back into her physical shape. She tumbled backward through the snow, her wings bent awkwardly as she crashed against the base of a coolant vat. She coughed, clutching her side as she stared at the swordsman in shock. He hadn't even used Haki, yet the force of his swordsmanship had completely shattered her defenses.

"You..." Monet stammered, her wings trembling as she struggled to stand. "The gap in our strength... it's..." 𝙧𝙚𝙚𝔀𝒆𝓫𝓷𝙤𝓿𝒆𝙡.𝒄𝙤𝓶

Zoro casually sheathed his blade, not even giving her a second glance as he walked past her battered form, stepping through the ruined blizzard wall.

"Tell the gas guy I'm coming for him next," Zoro muttered, his boots crunching loudly in the snow as he vanished down the dark corridor, continuing his search.

The Corridors of Building D

Meanwhile, Trafalgar Law was making his way toward the upper levels of Building D. His expression was a mask of cold, restrained irritation. His tactical mind, usually so sharp and calculated, was currently struggling to process the unbridled chaos of the Straw Hat Pirates.

Even from several sectors away, he could hear the muffled sounds of laughter, shouting, and what sounded like a giant giant-children's tantrum.

"They are a circus," Law muttered, his fingers tightening around the sheath of Kikoku. "An undisciplined, chaotic circus."

As he rounded a corner, he spotted a flash of red vest and blue shorts. Luffy was sprinting down the opposite corridor at breakneck speed, yelling at the top of his lungs.

"CAESAR! COME OUT! I'M GONNA KICK YOUR ASS!" Luffy shouted, his rubbery legs moving so fast they were a blur.

Law paused, opening his mouth to call out. "Mugiwara-ya! The office is in the opposite direction! You're going toward the—"

But Luffy was already gone, rounding another corner and disappearing from sight before Law could even finish his sentence. Law stood in the empty hallway for three seconds, his eye twitching. He slowly lowered his hand, letting out a heavy, defeated sigh.

"I don't care," Law muttered to himself. "I'll let him get lost. I need to secure my heart and capture Caesar. That is the only thing that matters."

Law continued his trek, heading straight for Caesar's personal office. But as he progressed deeper into Building D, his brow began to furrow.

The state of the corridors was deeply troubling.

The heavy steel doors were not just opened; they were completely obliterated, hanging off their hinges or melted into slag. Server panels had been ripped open, their wiring exposed and sparking, while strange, faintly glowing gold runes were burned directly into the concrete walls. There were no signs of a struggle from Caesar's men, but the level of destruction was staggering.

"Someone was here," Law murmured, his eyes scanning a severed security camera that had been cleanly cut by what looked like a high-intensity laser. "This isn't Mugiwara's doing. This is far too clean."

He reached the grand, double doors of Caesar's private office. The doors were unlocked, swinging open with a soft, ominous creak.

Law stepped inside, his hand instantly tightening on the hilt of his sword as his eyes took in the scene.

The office was in complete tatters. Caesar's desk had been cleared, his research notes and classified blueprints scattered across the floor like autumn leaves. The highly secure, reinforced steel safe in the corner had been bypassed entirely, its thick door swinging open to reveal nothing but empty shelves.

The safe was empty. His heart was gone. Caesar's backup files were gone. And Caesar himself was nowhere to be found.

Law's breath hitched. A cold, sinking feeling settled in his stomach.

"Ben," Law whispered, the name of the Straw Hat's mysterious magician flashing through his mind. "He did this. He swept through here before I could even get close."

Law ran a hand through his hair, his mind racing. If Ben had taken his heart, and if Caesar was already captured or dead, his entire plan to blackmail Donquixote Doflamingo was in jeopardy. The delicate balance of his strategy was crumbling before it could even begin.

He was about to turn around and sprint back to the playroom to confront the magician when a sudden, heavy shift in the atmosphere made him freeze.

The hair on the back of his neck stood up. A deep, suffocating pressure filled the room, accompanied by the slow, rhythmic sound of heavy boots clicking against the metal floorboards outside.

Law slowly turned around, his eyes narrowing to dangerous slits as a shadow fell over the office doorway.

Standing in the threshold was a tall, imposing man. He wore a pristine, quilted white coat that hung perfectly over his broad shoulders, and dark sunglasses that obscured his cold, dead eyes. In his right hand, he carried a polished bamboo stick.

But what made the entrance incredibly bizarre was the large, half-eaten piece of hamburger meat stuck firmly to his left cheek, slowly sliding down his jaw as he stood there.

"It has been a long time, Trafalgar," the man said, his voice deep, flat, and entirely devoid of any warmth. "You've grown since we last spoke."

Law's breathing stopped. The shadows of his past, the horrific memories of his childhood, and the agonizing screams of Corazon flashed through his mind in a split second.

"Vergo..." Law choked out, his voice dropping into a low, dangerous register.

"You were a crying, pathetic brat the last time I saw you," Vergo continued, completely ignoring the piece of meat stuck to his face as he adjusted his sunglasses. "Begging for the life of a traitor. And now, you are a Warlord of the Sea. How amusing."

"What are you doing here?" Law demanded, drawing Kikoku slightly, the steel of the blade catching the dim light of the office. "This island is restricted. And G-5 has no jurisdiction here."

Vergo let out a soft, dry chuckle. "Do you truly think we trusted Caesar? The Master of this facility is a volatile, prideful fool. We knew he would eventually make a mistake. That is why we sent Monet in as a deep-cover agent to monitor his progress from the start."

He tapped his bamboo stick against the doorframe. "I arrived on an inbound SAD tanker from Dressrosa. Joker wanted me to personally ensure that the production remained stable. But it seems you have brought quite a rowdy crowd with you, Trafalgar."

"I have nothing to say to you, Vergo," Law growled.

"You don't need to," Vergo replied calmly.

With a sudden, explosive burst of speed, Vergo vanished from the doorway.

Law's Observation Haki screamed a warning. He thrust his hand out, expanding his blue sphere of control. "ROOM!"

A split second later, Vergo materialized directly in front of him, his bamboo stick swinging in a lethal, horizontal arc toward Law's temple. The bamboo stick was no longer wood; it had been coated in a dense, glossy black layer of advanced Armament Haki, turning it harder than diamonds.

CLANG!

Law blocked the strike with Kikoku, the impact sending a massive shockwave of displaced air rippling through the office. The mahogany desk behind them was instantly cleaved in two by the sheer force of the collision.

Law gritted his teeth, his arms trembling as he felt the overwhelming, monstrous physical strength of the Vice Admiral.

"Your Haki has improved, Trafalgar," Vergo noted, his expression unchanged as he applied more pressure. "But you are still a child to me."

Law smirked, his eyes flashing with spatial energy. "Shambles!"

In a flash of blue light, Law swapped places with a scattered piece of paper on the floor, appearing directly behind Vergo. He swung his nodachi, unleashing a clean, spatial slash designed to cleave the Vice Admiral in two.

But Vergo's reflexes were monstrous. He spun around, his entire left arm turning glossy black as he coated it in Armament Haki. He met the blade with his bare forearm.

screeech!

The sound of metal scraping against hardened spiritual armor echoed through the room. Vergo's Haki was so dense, so incredibly compact, that Law's spatial slash couldn't penetrate the defense, the blade sliding harmlessly off his arm.

Vergo countered with a rapid, Haki-infused kick to Law's ribs. Law barely managed to bring his sheath up to block the blow, the force sending him skittering across the floorboards, his boots carving deep gouges into the metal.

They stood at opposite ends of the ruined office, their eyes locked in a silent, deadly promise of violence. The battle between the Warlord and the Vice Admiral was perfectly balanced, both possessing top-tier combat capabilities, and neither willing to yield a single inch.

The Central Corridors

Meanwhile, the G-5 Marines had successfully breached an alternate entrance to the facility, flooding into the metallic corridors with weapons drawn. They were searching for any sign of pirates when a loud, echoing voice made them halt.

"CAESAR! WHERE ARE YOU?!"

Luffy was sprinting down the central corridor, his straw hat bouncing on his back as he looked into every empty room they passed. "COME OUT AND FIGHT ME, YOU GAS-MAN!"

"Straw Hat!" a sharp, furious voice bellowed.

Luffy skidded to a halt, his sandals squeaking loudly against the metal. Standing in front of him was the body of Captain Tashigi, but her face was twisted into a snarl of pure, aggressive rage, two cigars clamped firmly between her teeth.

Directly behind her was the massive, hulking body of Vice Admiral Smoker, but she was currently blushing furiously, her hands frantically trying to pull the heavy coat together.

"Vice Admiral!" Tashigi (in Smoker's body) shouted, her voice booming unnaturally loud. "Please! Button up my shirt! You're showing my entire chest to the men! It is highly inappropriate and disgraceful to the Navy!"

"Shut up, Tashigi!" Smoker (in Tashigi's body) growled, exhaling a thick plume of smoke. "We have bigger problems! The pirate captain is right in front of us!"

Smoker didn't hesitate. He launched himself forward, utilizing Tashigi's smaller, agile frame to sprint across the metal corridor, his fist pulled back as he aimed a punch directly at Luffy's face.

Luffy simply tilted his head, his body swaying to the side with lazy precision. Smoker's punch sailed past his ear, hitting nothing but empty air.

"Whoa!" Luffy blinked, looking at the angry woman with cigars. "You're really slow! And who are you??"

"I am Smoker, you idiot!" the Vice Admiral roared, swinging a roundhouse kick at Luffy's ribs.

Luffy casually hopped backward, avoiding the kick with ease.

"Vice Admiral! Let me help!" Tashigi (in Smoker's body) called out.

She took a deep breath, attempting to tap into the powers of the Moku Moku no Mi (Smoke-Smoke Fruit) to create a binding wave of smoke to trap Luffy. She thrust her hands forward, concentrating with all her might.

Puff.

Instead of a torrent of dense, white smoke, Smoker's massive body merely let out a pathetic, tiny cloud of dark gray soot from his palms, followed by Tashigi violently coughing as the smoke got in her own throat.

"Cough! Cough! How... how do you control this stuff?!" Tashigi wheezed, her eyes watering. "It's so thick! It feels like my lungs are on fire!"

"You're doing it wrong, Tashigi!" Smoker screamed, his veins bulging on his forehead. "You have to disperse your cells! Don't just blow it out like a chimney!"

Luffy stared at the two of them, his expression turning from confusion to complete boredom. He crossed his arms, letting out a small sigh.

"You guys are really weak right now," Luffy noted, his tone entirely honest. "Your bodies are all mixed up. I don't want to fight you like this. It's not fun."

"Don't mock us, pirate!" Smoker snarled, preparing to charge again. "We are going to arrest you and throw you straight into Impel Down!"

"No thanks!" Luffy grinned, turning around. "I'm looking for the gas guy! See ya!"

With a sudden burst of speed, Luffy sprinted away, his rubbery legs moving so fast he became a blur of red and blue down the corridor.

"Get back here!" Smoker roared, chasing after him.

But Tashigi's physical body, even under Smoker's hardened willpower, simply couldn't match Luffy's monstrous speed. Within seconds, Luffy had completely outpaced him, rounding a corner and leaving the screaming Marine far behind.

Tashigi (in Smoker's body) tried to run after them, but her lack of coordination with the smoke powers made her stumble, her massive limbs tangling as she nearly crashed into the wall.

"Curse it all!" Smoker growled, slamming Tashigi's fist against the metal wall in frustration. "In this body, I can't even touch him!"

The G-5 Marines gathered around them, looking completely helpless as the Straw Hat captain effortlessly ran circles around their command.
