Xun Xun forced himself calm, but his clenched fists trembled like leaves in a crosswind. His reddening eyes burned like embers ready to spill tears. He needed cool reason, or his chance to escape would thin like mist at dawn.

The bodyguard behind him was the only shore in a storm. Xun Xun whispered the news, and the man’s face tightened like iron cooled too fast. A chip buried in a free person’s brain to control them—an idea as venomous as a serpent in milk.

He started calculating with a civilian’s map and a soldier’s frown. He weighed Xun Xun’s strength and the underground gate like a mountain. It looked hard as black ice. He couldn’t find another path, only shadows and locked doors.

“If we find a vent, it’s a breeze… He’s back.” His murmur drifted like smoke. Another guard finished talking with a doctor. The doctor entered and said the operation needed an hour to prep. Until then, Xun Xun could walk anywhere without a “No Unauthorized Personnel” sign, so long as he didn’t stir the hive.

Xun Xun shot the bodyguard a look, a spark under ash. The man understood; opportunity glimmered like a slit of light. Xun Xun would scout the Modification Center, hunt for escape lines—sewers like dark rivers, vents like silver throats.

They moved through a corridor and reached a junction like a crossroads in fog. Lab coats clustered around a single computer, recording data like scribes at a shrine. Xun Xun leaned in, curious as a cat, but a lab coat blocked him like a gate.

He refused to rattle the hive, but he stole a glance like a thief of stars. He caught a few words—“something King”—then lost the rest behind shoulders and glare.

He circled the area like a hawk and found no vents, only sealed breath. How did these people live without air? Humans don’t bloom without oxygen, unless they were all rebuilt bodies with iron lungs.

A Mechanical Arm already cost a small fortune, a mountain of coins. Internal organs were a deeper ocean he couldn’t price. Replacing lungs for many would devour time, labor, and treasure like a hungry god. No ordinary outfit could shoulder that.

He checked several rooms like a lantern sweeping walls. Finally he found a vent, a silver mouth in a shadowed room. Metal baffles welded it shut like armor, leaving only thin outlets that sighed. It screamed, no entry, no escape.

He had to admit the security was tight as winter bark. The place gave him no breath, no path, like a maze that hated living feet.

The bodyguard stayed close, a shadow stitched to his heel. He saw the vent too and glanced at his Mechanical Arm like a hammer weighing a nail. If the weld was normal, a full-force blow might crack it like old ice.

Where there’s a vent, the employee restroom can’t be barren. This was underground, a buried whale with lungs.

He excused himself to the restroom and found another vent welded shut, a mouth sealed by iron. He tried everything short of thunder, but he couldn’t open it without rattling the lab coats like stirred bees.

The weld was dead-solid, a seal like a tomb. Without proper tools, only brute force remained, and brute force cries like drums. Labs have alarms; ripping it open would draw eyes like crows to carrion. He told Xun Xun, hoping the young master would cut his own path.

Xun Xun had a plan, but it needed strength like a blade needs edge. He was just a soft-handed rich kid, a second son adrift. What strength could he claim?

Wait—strength?

He looked at his blackened right hand, a burned root. His arm had failed, and his father sent him to install a Mechanical Arm, a path of iron to power. That was a door.

If his hand hadn’t broken, the bodyguard might still have brought him here, through another gate. He almost thanked the clotted mud that ruined his palm, a poison that turned into a key. Otherwise, he’d see no dawn at all.

An hour passed like sand pouring from a cracked vase. The lab coats finished prep for the Mechanical Arm transfer. The bodyguard handed a chip to a lab coat. The lab coat understood, the nod thin as paper.

The bodyguard at Xun Xun’s side shook his head, despair flashing like a blade’s dark shine. He tasted guilt like bitter tea. Xun Xun steadied him with a quiet look. He wasn’t clever, but he was a rich heir, and heirs carry hidden threads.

Guards weren’t allowed inside the operating room. Xun Xun entered with the lab coat, and the man gestured at the bed, a white island under a cruel sun.

“This is general anesthesia?” His voice was a still pond with ice under it.

He saw the syringe, clear as winter rain, and his eyes cooled like stone. He pointed at the needle and said, each word a falling bead, “I don’t need that.”

The lab coat blinked, then ignored him like wind through reeds. He thought it was a joke and urged Xun Xun onto the bed. The surgical light flared like a noon sun, while the room lay dark as a cave. That light looked like his only star.

“I don’t need it. I’m not joking.” His tone was frost on glass.

He stepped forward, snatched the anesthesia box like a falcon, and threw it far, a clatter like bones. He repeated himself, word by word, a drumbeat.

“You don’t want your coworkers to know you took the money, right?” His voice held a thin smile like a blade under silk.

He recognized the bribed lab coat, a coinprint on a sleeve. Panic flickered in the man like startled fish. He didn’t know how Xun Xun knew, but exposure would strip him bare—no pay, cold stares, job gone like smoke.

He didn’t dare cross Xun Xun, so he whispered to the lead surgeon, a plea like water on stone. The surgeon had watched everything with dry eyes. If the patient refused anesthesia, so be it. They weren’t saints in a grand hospital; they were coin and iron.

The operating room had cameras, cool unblinking eyes. Xun Xun had waived anesthesia; if he broke, their hands stayed clean like winter snow.

“One more question. You install the prosthetic first, right?” His voice was calm as rope.

The surgeon nodded, annoyed, a sigh like a valve hiss. Just lie down and die—no, lie down and let us work. Stop with the questions.

Once everything was confirmed, Xun Xun lay on the bed, eyelids heavy under the blinding light. He felt the cold blade kiss his ruined tissue, a winter wind shaving bark.

His arm had been corroded by sludge and charred black by Night Frost’s fire, yet nerves still clung like roots in ash. Cutting them hurt, unavoidable as thunder after lightning.

He didn’t move. His longing for freedom and fear of a chained mind pressed like mountains. He crushed his reflexes like a snake under a boot. If the surgery failed, his hope would crack like clay. This was his only sky.

Dead bone slid out of him, inch by inch, like a pale snake pulled from earth. The torn end screamed like split wood, and he grunted, low as a drum. Then he clenched his teeth and fell silent, counting each inch by pain. Cold prosthesis replaced bone, steel for marrow.

Metal sank into him, a river of iron joining flesh. The Array Pattern above woke like a sleeping vine and crept toward living tissue in slow silver curls. A lab coat poured a cell-proliferation agent into the wound, a tonic with bonds like salt. It burned like salting raw meat, the pain savage as a tiger bite.

He lost time to pain, mind blurred like rain on glass. The surgeon noticed and softened, a wisp of humanity like warm smoke.

“Inject anesthesia. Final suturing.” His words were a gate swinging open.

Xun Xun snapped awake, a hawk unhooded. “No!”

The surgeon was surprised, brows lifting like leaves. He hadn’t expected Xun Xun to endure this far. He knew the file—an heir from a grand clan, a silk robe with a spine.

Respect settled in him, a quiet bow. Adhesive and stitches linked the Mechanical Arm to Xun Xun’s shoulder like rivets to a hull.

The arm proved cutting-edge, a marvel like moonlight on steel. It replaced dead nerves and gifted touch, a phantom turned real. The moment it sealed, sensation bloomed like spring on iron.

Sutures finished, the surgeon turned toward his next case. Then blasts rolled from a nearby research room, thunder beating walls. The alarm blared, a red howl that drilled every ear.

“We’re under attack inside!” The shout leapt like sparks.

Xun Xun exhaled, breath easing like rain. The plan had begun.

He’d learned the lab had alarms; internal damage would wake them like gongs. The bodyguard would smash the restroom hall vent, drawing guards like wolves to a single clearing. Then they would meet and flee through the restroom pipes, rivers of dark escape.

Because of the alarm, the surgery paused like a song cut mid-note. Xun Xun grabbed the lab coat and slapped him aside, an open palm that cracked like thunder. He marveled at the Mechanical Arm’s strength, a power like a hidden furnace. Then he bit down on pain and opened the operating room door, a rectangle of light like a window in a storm.

He stole the lab coat’s clothing, white shell over a beating heart, and bolted. The bodyguard outside saw a doctor sprint out and assumed urgent duty, a comet with a tail.

Then a man in a white T-shirt stumbled from the room, one hand pressed to a swelling cheek, words tumbling like stones. “What are you staring at? That’s your young master!”

The bodyguard froze, fear and anger surging like floodwater. He couldn’t let Xun Xun leave; the chip had to be planted, or the man wouldn’t see tomorrow’s sun.

Xun Xun was slow, still weak, a bird flying with new wings. In half a minute, the bodyguard closed in, steps heavy as drums.

His steam-powered arm fired, a piston punch that slammed Xun Xun’s spine like an iron ram. Fresh from surgery, still ghost-pale, Xun Xun took it full. Blood sprayed from his mouth, stark as a red banner.

Face white as porcelain, he scanned the hall for shelter, eyes hunting like a fox. A sign gleamed ahead like a hard rule: “No Unauthorized Personnel.”

Those four characters cut the air like blades. Xun Xun clutched his shoulder, glanced back at the charging bodyguard, and grit his teeth. Then he rushed in, a startled stag breaking into dark trees.
