Chapter 17 — The Deep Dive
Kai moved from bridge to bridge, ship to ship, his bare feet slapping against wet wood and rope as he made his way toward the rear of the diamond formation.
The fleet stretched out behind him like a dark arrow aimed at nowhere. Supply vessels to his left. Weapon ships to his right. Crew carriers ahead. But he wasn't stopping at any of them. He was heading to the very end — the last ship in the formation. The one that didn't quite fit.
He found it.
The vessel was larger than he expected — not in length, but in bulk, sitting lower in the water than the others, its hull dark with age and neglect. Barnacles crusted the sides like armor. The wood was stained with things Kai didn't want to identify. And the people on deck…
They were the worst-looking creatures he had ever seen.
Not monsters. Not in the physical sense. But their faces — scarred, sunken, hollow-eyed — told stories of violence and desperation. Most of them wore chains. Heavy iron collars around their necks. Shackles on their wrists. They moved slowly, deliberately, as if every step required permission from someone who rarely gave it.
Guards stood at intervals along the deck — heavily armored, weapons drawn, watching the chained prisoners with the cold patience of executioners waiting for an excuse.
Kai walked past them without stopping.
The first lower deck was exactly what he expected — a jail cell. Rows of iron bars. Men and women pressed against the rusted metal, their hands reaching through the gaps, their eyes following him as he passed. Some whispered. Some spat. Some just stared.
He kept walking.
The second lower deck was different. This was a working area — forges and anvils, chains and pulleys, the smell of coal and sweat and something metallic. Workers moved between stations, their faces grim, their bodies covered in soot.
Kai found the stairs leading further down.
Four decks, he thought. No other ship in the fleet has four decks.
He descended.
The fourth deck was small — barely a room, really — with walls of thick iron and a floor that seemed to be made of something darker than wood. In the center of the room stood an old man.
A dwarf.
He was short — barely reaching Kai's chest — but wide, his shoulders thick with muscle that had been built over decades of hard labor. His beard was long and grey, hanging past his belt, tangled and singed at the edges. In his hand, he held an iron hammer.
The hammer was old. Cracks ran across its surface like dried riverbeds. The head was chipped in a dozen places. But the metal still gleamed in the dim light, and something about the way the dwarf held it — the weight, the balance, the familiarity — told Kai that this hammer had been used for a very long time. And it was still deadly.
The dwarf looked up.
"Who are you?" His voice was rough, like stones grinding together. His eyes — small, dark, sharp — scanned Kai from head to toe.
Kai clasped his hands together and bowed slightly.
"My name is Kai. I'm here to join the underwater sea dive."
The dwarf stared at him.
Then he laughed.
It wasn't a friendly laugh. It was the laugh of someone who had heard something so absurd that laughter was the only reasonable response.
"You want to dive into the black water?" The dwarf shook his head. "You're not a criminal. I can see that. You're not a guard. You're not one of my workers. So why? Tell me why a free man would volunteer for a death sentence."
Kai held the dwarf's gaze.
"Because I'm weak."
The dwarf's laughter stopped.
"Compared to the danger that's coming," Kai continued, his voice steady, "I'm nothing. The things in the black water almost killed me once. And the things in the Empty Waters…" He took a breath. "If I want to protect anyone, if I want to survive, I need to get stronger. I need to do whatever it takes. No matter how dangerous. No matter how painful."
He looked the dwarf directly in the eyes.
"I'm going to do every single thing that makes me strong."
The dwarf was silent for a long moment. Then he nodded slowly.
"Stand in the corner," he said. "Over there. The dive starts in a few minutes. More are coming."
Kai moved to the corner of the room and waited.
---
They came in chains.
One by one, the prisoners descended the stairs — men and women of every race Kai had seen and some he hadn't. Orcs with tusks broken and re-grown. Elves with hollow eyes and scarred faces. Humans with the build of people who had spent their lives fighting. Beasts that walked like men but had fur and fangs and claws.
All of them were roughed up. All of them had scars — fresh ones, old ones, layers of damage that told stories of violence survived and repeated. Their muscles were thick from forced labor. Their bodies were hard from neglect. And they were ugly — not in the way of natural features, but in the way of people who had been broken and never properly put back together.
Guards followed them down — heavy armor, heavy weapons, heavy footsteps. They arranged themselves around the room, watching, waiting.
The dwarf raised one hand into the air.
He snapped his fingers.
The sound was not loud. But it rang — a sharp, metallic note that cut through the noise of the room and silenced everyone instantly. Every eye turned to him.
"Listen," the dwarf said, his voice carrying without effort. "Today's expedition is about clearing a snake monster. I've been watching it for two days. It's been following us. Getting closer. If it reaches the fleet, it will tear through these ships like paper."
He looked around the room, meeting each pair of eyes in turn.
"Your job is simple. Kill it. Or die trying. Pick up your weapons and get ready."
He turned and walked out of the room.
Kai stood still, processing.
We're hunting a sea serpent.
Footsteps approached him. Two guards, their armor dark and unmarked, their faces hidden behind helmets with narrow eye slits.
"Kai, right?" one of them said. "We heard about you. The human who fought the dragon candidate. The one who wears a succubus artifact."
Kai nodded. "That's me."
The second guard laughed — a short, bitter sound. "And now you're here. Volunteering for a death dive. What did you do? Commit a crime? Because I don't see chains on your wrists."
"No crime," Kai said. "I'm here to train."
The guards stared at him.
Then both of them burst out laughing.
"Train?" the first guard gasped, doubling over. "Are you serious? This isn't training, you idiot. This is a death sentence. If I had any choice, I'd be running in the opposite direction as fast as my legs could carry me."
The second guard shook his head. "The deep sea isn't a joke. The pressure alone will crush an ordinary person. The cold will stop your heart. And the waves…" He shuddered. "The waves cut. They don't push — they cut. Like blades made of water. If you survive the creatures, the water itself will tear you apart."
Kai listened.
They're telling me things I already know, he thought. Things I've already experienced. The cuts. The cold. The pressure. I felt all of it when I fell into the black water before.
But I survived.
And if I want to get stronger, I need to do it again.
The dwarf — Dorrek, Kai learned from a nearby whisper — returned to the room. He raised his hammer high above his head.
Then he brought it down.
CRACK.
The sound was not iron on stone. It was something else — something magical, something old. The hammer's head glowed briefly, and from the glow, chains erupted. Not ordinary chains — these were made of light and shadow, solid and spectral at the same time. They shot across the room, wrapping around every prisoner, every volunteer, wrapping around Kai.
The chains tightened around his waist.
They were warm. Almost comfortable. And beneath the warmth, Kai could feel something else — a thin layer of energy spreading across his skin, like a second suit, invisible but present.
Protection, he realized. The chains aren't just holding us. They're shielding us.
Dorrek raised his hammer again.
He struck the floor.
The ground beneath Kai's feet vanished.
---
The black water hit him like a fist.
Cold. Crushing. Absolute. He had a single second to fill his lungs before the darkness swallowed him completely, and then he was in it — dragged by the chains, pulled along by the ship's momentum, the water pressing against him from every direction at once.
The pressure was immense. He could feel it squeezing his chest, his skull, his bones. The cold was worse — not the cold of winter or the cold of deep lakes, but the cold of places that had never known warmth. It seeped into his muscles, his joints, his very blood.
But the chains held.
The energy layer on his skin absorbed the worst of it, deflecting the cutting force of the water, keeping his body intact. He could still feel the pressure, still feel the cold, but he wasn't being torn apart. Not yet.
He looked around.
The prisoners were all around him — some screaming, some silent, some already dead. The chains kept them attached to the ship, dragging them through the black water like bait on a fishing line. Their bodies bounced and twisted in the current, arms and legs flailing uselessly.
Guards floated nearby, their heavy armor making them sink faster than the others. They carried weapons — crossbows with multiple bolts, axes with serrated edges, harpoons with barbed tips.
And then Kai heard the scream.
He turned.
A man — one of the prisoners — was gone. In his place was a massive jaw, lined with teeth the size of swords, closing around empty water. The serpent had struck from below, fast and silent, swallowing the man whole before anyone could react.
There.
Kai saw it now — a shape in the darkness, long and thick, coiling through the water like a river made of muscle. Its scales were dark green, almost black, blending perfectly with the black water. Its eyes were yellow, slit-pupiled, glowing faintly in the depths.
The serpent was enormous. Not as big as the tree monster Kai had fought before, but close. Close enough.
The guards raised their crossbows and fired.
Bolts streaked through the water — seven, eight, ten of them — all aimed at the serpent's head. They struck. They bounced off. The scales were too thick, too tough, turning aside the arrows like they were made of paper.
The prisoners with axes charged.
They hacked at the serpent's side, their blades biting into the scales but not penetrating. The serpent ignored them. It opened its mouth and lunged, swallowing two more prisoners in a single bite. Their axes clattered against its teeth and then disappeared.
More prisoners attacked — these with hammers and maces, swinging with all their strength. The blows landed. The serpent's head jerked with each impact. But the scales held. The creature didn't bleed. It barely seemed to notice.
Then it opened its mouth again.
This time, it didn't lunge. It spat.
A stream of purple venom shot through the water, spreading outward in a cloud, turning the black water into something toxic and deadly. The prisoners who were caught in it screamed — their skin bubbling, their flesh melting, their bodies dissolving into nothing.
The cloud rushed toward Kai and the guards and Dorrek.
The dwarf raised his hammer.
He spun it — not swung, but spun, the head rotating in a circle so fast it became a blur. The spinning hammer created a vortex, a wall of force that pushed the venom back, deflected it, protected everyone behind it.
The purple cloud parted around them like water around a stone.
Kai didn't wait.
He pushed off from nothing — from the water itself, his legs driving against the resistance — and shot toward the serpent.
---
The serpent surged straight at him.
Its massive body cut through the black water like a living spear, its jaws already opening, already hungry. Kai's eyes locked onto the yellow glow of its pupils, and he moved.
He kicked sideways.
The motion was sharp, explosive, his leg driving against the water with everything he had. The serpent's jaws passed just beside his torso — close enough that he felt the wind of its passage, close enough that his coat brushed against its teeth.
His hand shot out.
His fingers found a fold of thick scales along the serpent's neck — a gap between the armor plates, a weak point. He grabbed on, using the creature's own speed to swing himself onto its side. His body slammed against the scales, the impact jarring his bones, but he held on.
His knee drove upward.
The strike slammed into the underside of the serpent's jaw — soft tissue, vulnerable flesh. The creature's head snapped slightly off course, its bite missing its target by inches.
Kai didn't stop.
He dragged himself higher, climbing the serpent's neck, his fingers finding hold after hold in the gaps between scales. The creature thrashed beneath him, trying to shake him loose, but he held on. His elbow came down — once, twice, three times — each strike landing on the same spot beneath the jawline.
CRACK.
The blow jolted through the serpent's head. Its mouth snapped shut with a violent burst of bubbles, teeth clanging against teeth. The creature twisted sharply, its body coiling, its tail whipping through the water toward Kai.
He saw it coming.
He let go of the serpent's neck and dropped, the tail passing over his head, missing him by less than an arm's length. He caught hold of the tail as it swept past — not the tip, but the thicker part, near the base — and held on.
The serpent dragged him through the water.
Faster. Faster. The pressure increased, the cold bit deeper, but Kai didn't let go. He pulled himself along the tail, hand over hand, climbing toward the creature's body. The serpent's scales scraped against his palms, drawing blood, but he kept moving.
He reached the main body and drove his fist into the serpent's side.
The impact was solid — his knuckles sinking into the scales, the force traveling through the creature's flesh. The serpent shuddered but didn't slow. It surged forward, faster now, angling toward something.
Kai looked up.
The ship.
The serpent was heading straight for the fleet — for the last ship in the formation, the prison vessel. Its massive body cut through the water with terrifying speed, closing the distance in seconds. If it reached the hull, it would tear through the wood like paper. The ship would sink. Everyone on board would drown.
Kai moved.
He released the serpent's body and swam alongside its head, matching its speed, staying just beside its snapping jaws. The creature tried to bite him — once, twice, three times — but he dodged each attack, twisting and turning in the water like a fish avoiding a net.
The serpent lunged again.
This time, Kai didn't dodge.
He darted forward, angling along the side of the creature's head. His hand struck against its snout — not a punch, but a redirection, pushing the massive head slightly sideways as he slipped past the line of its fangs.
His other arm snapped forward.
His fist hammered across the side of the serpent's face, just below the eye. The impact was brutal — he felt the creature's skull shift beneath the scales, felt something crack beneath his knuckles.
The serpent recoiled.
Its head pulled back, its body coiling in anger. But it didn't retreat. Its movements became faster, more unpredictable, its jaws snapping at the water where Kai had been a moment before.
Kai twisted his body and drove a sharp kick into the base of the serpent's jaw.
The blow was perfectly placed — hitting the same spot he had been targeting since the fight began. The serpent's mouth slammed shut with a heavy crack that echoed through the water. Blood — dark, thick, almost black — seeped from between its teeth.
The creature's yellow eyes blazed with fury.
It surged forward again, faster than before, its body a blur of scales and muscle. The ship was right behind it now — so close that Kai could see the barnacles on the hull, could see the chains dragging through the water, could see the guards and prisoners watching from above.
The serpent opened its mouth.
And Kai dove straight into it.
