My Unique Adaptation Skill in Another world-Chapter 18 - 17: Into the fog

The storm raged through the night.

Leo lay in his quarters, gripping the edges of his bed as the ship pitched violently. Water crashed against the hull in thunderous waves, and above him, he could hear the crew shouting commands, their voices barely audible over the wind.

He tried but couldn’t sleep until eventually, exhaustion dragged him under.

When Leo woke, the world had gone silent.

He sat up slowly, disoriented, the ship still rocked gently beneath him, but the violent pitching had stopped, no rain hammered the deck above, no wind howled through the rigging.

Just... silence.

Leo dressed quickly and climbed the stairs to the main deck.

A fog surrounded the ship.

It was thick, impossibly thick, pressing in from all sides like a living thing. Visibility extended maybe thirty feet before the world dissolved into gray nothingness. The air felt heavy, oppressive, and wrong in a way Leo couldn’t articulate.

Then he remembered the feeling.

They were now in a mana zone.

It pressed against his skin like static electricity, dense and overwhelming. He’d felt mana before, in the forest during the hunt, but this was different. This wasn’t just ambient energy, this was like trying to breathe underwater.

"Here we go again... Maybe this time is better" Leo thought, letting out a deep sigh "... I hope I didn’t just trigger a death flag"

At the bow of the ship, something glowed.

Leo moved closer, pushing through crew members who worked in tense silence. As he reached the front railing, he saw it properly.

A massive wayfinder stood mounted at the ship’s prow, easily ten feet tall, made of dark metal etched with glowing runes. Light pulsed from its core in steady rhythms, cutting through the fog just enough to illuminate the water ahead. The magic emanating from it felt different from the zone’s mana, it was cleaner.

"Don’t stare at it too long," a voice said beside him.

Leo turned. One of Iori’s guards stood nearby, hand resting on his sword.

"How long until we’re through?" Leo asked.

"Four days." The guard’s expression was grim. "If we’re lucky."

Leo looked back at the fog, at the oppressive gray that swallowed everything beyond the ship’s immediate vicinity.

"Stay alert," the guard continued.

Before Leo could respond, the guard moved away, rejoining his patrol.

Leo scanned the deck. Everyone was armed. Guards positioned at regular intervals, weapons drawn. Crew members moved with practiced efficiency, but there was tension in every motion.

Near the stern, Iori stood with her twin katanas already strapped to her waist. She spoke quietly with the ship’s captain, a grizzled beastman with gray in his beard and scars across his knuckles. Their conversation was brief, serious.

When Iori noticed Leo watching, she crossed the deck toward him.

"You’re awake," she said.

"Hard to sleep through a storm like that."

"You get used to it, besides the zone is worse." She glanced at the fog. "We’re passing through the edges, which is the safest path through, but ’safe’ is relative."

"What should I expect?"

"Anything." Iori’s hand rested casually on one katana hilt. "Usually I would count out pirates like I told you before but I’ve been informed that they are under new leadership"

"So, we just sail through and hoping for the best?"

"We sail through prepared for the worst," Iori corrected. "Stay ready, if and when fighting starts, make sure you don’t hesitate."

She turned to leave, then paused. "I guess you’ll showing the fruits of our training soon enough".

Hours passed.

The fog never changed. Time felt meaningless, no sun visible, no sense of progress, just endless gray and the steady pulse of the wayfinder cutting through it.

Leo stayed on deck, Defiance and Resolve strapped across his back. He practiced aura circulation quietly, cycling energy through his body in controlled loops the way Iori had taught him. Without adaptation helping, every repetition required conscious effort.

Around him, the crew remained vigilant but silent. Even the usual sounds of a working ship, ropes creaking, sailors calling to each other, were muted, swallowed by the oppressive atmosphere.

Then someone shouted.

"Contacts! Port side!"

Leo spun, hand moving to Defiance’s hilt.

Shapes materialized from the fog, dark silhouettes resolving into ships. Small, fast vessels with tattered sails and hulls reinforced with scavenged metal. Three of them, no, four.

Pirates.

They didn’t call out, didn’t demand surrender, they just attacked.

Grappling hooks flew through the air, iron claws biting into the ship’s railing. Pirates swarmed up the ropes with terrifying speed, wild-eyed, weapons raised, screaming war cries that echoed through the fog.

The ship’s defenders met them instantly.

Guards surged forward, blades flashing. The first pirate over the railing lost his head before his feet touched the deck. The second managed three steps before a spear took him through the chest.

But more kept coming.

Leo drew both swords and moved.

A pirate came at him, scarred face, jagged cutlass, teeth bared in a savage grin.

Leo sidestepped the wild swing and brought Defiance down in a heavy arc. The weight manipulation activated instinctively, making the blade heavier mid-strike, and it crashed through the pirate’s guard, shattering the cutlass and driving the man to his knees.

Resolve followed, a quick thrust that caught the pirate in the throat.

Blood sprayed hot across Leo’s hands.

The pirate gurgled, hands clawing at the blade, and Leo pulled back.

But the blade didn’t come free.

It stuck.

No, not stuck. It was drinking.

Leo felt it through the hilt, a subtle pull, like suction. The pirate’s eyes went wide, mouth working soundlessly. Blood didn’t just pour from the wound, it flowed into the blade, pulled by something inside the metal.

The pirate’s skin paled rapidly, his struggles weakened.

Leo stood frozen, watching in shock as Resolve drained the man dry in seconds.

"What the fuck—"

The pirate collapsed, lifeless, and Leo finally yanked the blade free. It came away clean, almost polished, as if the blood had been absorbed entirely.

But there was no time to process.

Another pirate rushed him. Leo turned, brought both blades up, and moved.

The fight became chaos.

Pirates swarmed the deck like rabid animals, no coordination beyond following their targets, no regard for their own lives, they threw themselves at the defenders with savage glee, laughing even as they died.

But they weren’t mindless. Some were good. Skilled swordsmen who moved with precision, who exploited openings, who forced Leo to actually work for every kill.

He parried a strike aimed at his throat, countered with Defiance, felt the blade grow heavy as it cleaved through ribs. Resolve followed, opening the pirate’s side, and Leo felt the pull again, the blade drinking deep.

Around him, Iori’s guards fought with brutal efficiency. They moved as a unit, covering each other, cutting down pirates with practiced ease. These weren’t amateurs, these were warriors trained by one of the great houses.

And then there was Iori.

She moved through the battle like a force of nature. Her katanas blurred, each strike ending a life. She didn’t draw unnecessary attention, didn’t waste movement on displays of power. She just killed, over and over, with terrifying precision.

A pirate tried to flank her. She took his legs out without looking.

Another came from above, dropping from the rigging. She stepped aside, let him crash to the deck, and ended him before he could rise.

She wasn’t even using aura, just pure skill.

The pirates fell back, scrambling over the railings toward their ships, laughing and shouting as they retreated.

"This was just a taste!"

"We’ll be back!"

"You’re ours! All of you!"

Their ships melted back into the fog, cackling threats fading into the distance.

Silence settled over the deck.

Leo lowered his swords, breathing hard. Blood soaked his hands, his clothes. Around him, crew members checked each other for injuries, while others dragged pirate corpses toward the rail.

No one from the crew had died. A few injuries, nothing fatal.

Iori sheathed her katanas and moved to the ship’s captain, speaking in low tones.

Leo looked down at Resolve. The blade gleamed faintly in the wayfinder’s light, no trace of the blood it had consumed.

"The blacksmith said it fed on blood, But he didn’t mention this." Leo thought. "He also said something about durability negation, but what does that even mean in a fight like this?"

Before he could dwell on it, a sound rolled through the fog.

Deep, resonant, like the world groaning.

Everyone froze.

Leo’s stomach dropped, that wasn’t a ship, that wasn’t wind.

The sound came again, closer this time, accompanied by something else, a massive displacement of water.

"Captain!" someone screamed from the crow’s nest. "Something in the water! Multiple contacts! Big!"

The fog ahead began to churn.

Then it emerged.

The creature rose from the water like a living island, scales the size of shields, a serpentine body that disappeared into the depths even as its upper half towered over the ship. Its head alone was larger than the entire vessel, jaws lined with teeth like sword blades.

Twenty stories tall. Maybe more.

And behind it, shapes in the fog. More of them. Different sizes, different forms, all massive.

The wayfinder’s light caught their eyes, dozens of them, glowing in the dark like lanterns.

They were approaching the edge of the zone.

And the creatures were coming to meet them.

"BRACE!" the captain roared.

The first creature lunged, jaws opening wide enough to swallow the ship whole.

Iori moved.

She didn’t run toward the threat. She ran toward Leo.

Her hand grabbed his shoulder, and suddenly his skin burned. Aura flared between them, bright, searing, leaving a mark that pulsed with her energy. It felt like a brand, hot and alive, settling deep into his flesh.

"What—"

"Don’t die," Iori said.

Then she turned and jumped.

She launched herself off the railing, katanas drawn mid-leap, straight toward the creature’s open maw.

Her blade flashed.

The creature’s head snapped to the side, a massive gash opening across its snout. It roared, twisting away from the ship, and Iori landed on its back, already moving, already cutting.

Another creature surged from the fog.

Iori was there.

And another.

She met it, diverted it, drove it back.

The crew stood frozen, watching as she carved through titans alone, keeping them away from the ship, with an unholy show of force and power.

"MOVE!" the captain bellowed. "Get us through! NOW!"

The ship lurched forward, rigging groaning as the crew adjusted sails.

Behind them, the sounds of battle echoed through the fog, metal against scales, roars of rage, the thunder of displaced water.

Iori fought alone in the mist.

And the ship sailed on without her.
