Night did not fall. It switched on. One moment, the artificial sky was a dim gray sheet stretched over steel treetops. The next, the light died as though someone had pulled a cable from the spine of the world. No sunset. No warning. Just— Off. Darkness dropped over the forest in one solid mass, heavy enough to feel like cold metal lowered across their shoulders, while the temperature collapsed in the same instant and moist air tightened around mist crawling from the soil to wrap their ankles like damp bandages.
Ten inhaled. Then immediately coughed, hard and ragged, as if the cold had grown claws inside his throat.
"S-so cold…" His voice came out smaller than he intended. Jin cursed under his breath and folded his arms across his chest.
"A few minutes ago, this place was trying to cook us. Now it's a freezer." His eyes searched the black between the trees.
"This Tower has a sick sense of humor." Z-69 did not answer. He stood still with his head slightly tilted. Listening. Not the way humans listened for sound. The way predators listened for shape inside silence. The forest had changed. Not merely darker. Sharper.
The trunks remained where they had been, metallic leaves still overlapped above them, and the artificial sky had merely gone black, yet the space between every object felt rearranged—as though Floor Four had spent daylight pretending to be an ecosystem and had finally remembered that it was an execution device. A slow scrape moved somewhere far away. Metal against metal. Measured. Intentional. Z-69's right hand settled near the compact micro-cell pistol. His left remained around the Heaven-Sundering Short Blade.
The firearm stayed holstered. Its cell was limited. Worse, every kinetic flash in complete darkness would reveal their position and teach whatever watched them the rhythm of his shots.
"We need shelter." Ten swallowed.
"You feel it too?"
"Instinct," Z-69 said.
"Night changed the rules." Jin forced out a dry laugh.
"Don't say it like that. You make everything worse." Z-69 looked at him.
"It is worse." They moved. Fast, but not recklessly. Daylight had taught them enough. Panic was blood in water, and the forest had already demonstrated enough intelligence that, if it wanted them to run, it would place traps along the obvious path, while any shelter offered too conveniently would merely be a kill zone waiting for occupants. Ten dropped to one knee and pressed his palm against the cold soil. His eyes closed, and the tremor in his breathing slowly steadied.
He listened through the ground the way a spider listened through its web.
"There." He pointed toward a cluster of massive exposed roots twisted together like black ribs.
"Less vibration. Nothing large has used that area recently. It feels… quiet." Jin vanished in a short burst. Not far. Only enough to scout without exhausting himself. He returned a second later, boots scraping softly across the soil.
"No clear trail leading to it. Canopy's thinner on the west side, so that's the most likely approach. More angles from above." Z-69 nodded once. Enough information. They moved beneath the roots. The hollow was not comfortable: time, artificial weather, and something with claws had scraped the interior clean, leaving cold metal, wet bark, and old animal musk beneath roots dense enough to break sight lines but nowhere near strong enough to survive a sustained assault. Not safe. Cover.
On Floor Four, that distinction was wealth. Z-69 cut several flexible metal branches and wedged them into a crude barricade across the widest opening. Controlled cuts. No lightning. No bright flare. One careless spark in this darkness would become an invitation. Ten gathered thick metallic leaves and layered them over the ground for insulation. His fingers shook from cold, exhaustion, fear, and whatever injuries the Tower had decided were not important enough to heal properly.
Jin circled the perimeter and built simple warning traps: strands of vine-metal stretched across approach angles, loose bark positioned to rattle, and thin branches balanced where a careful foot would still disturb them. Not lethal. Only enough to tell them where death was approaching from. They finished as the darkness deepened again, as though the forest had waited for them to settle before leaning closer. Ten sat beneath the roots and hugged his knees.
"It's… dark and cold." Z-69 raised two fingers. A filament of violet electricity appeared between them, no brighter than a dying ember. Thin light distorted their faces and turned their eyes into wet glass. Ten's shoulders loosened by a fraction.
"Now it's only cold and mostly dark."
"I'm keeping it weak," Z-69 said.
"Enough to see each other." Even that tiny current bit backward into the corpse tissue conducting it. A black hairline appeared across one fingertip before the violet crystal quietly repaired the damage. Cheap. Not free. Jin laughed softly without looking away from the barricade.
"Good. I'd rather not die because we illuminated ourselves like an advertisement." For several seconds, nothing happened. That made it worse. The silence was not peace. It was expectation. Night carried different sounds from day. No Scarabs clicked beneath the ground. No giant worm disturbed the deeper layers. Nothing moved loudly enough to identify itself. Only fragments. Metal brushing metal. Weight shifting over leaves. Then— A soft, irregular breath. Not Ten's. Not Jin's.
Z-69 performed the motion of breathing only from obsolete habit. The sound did not belong to him either. Ten stiffened.
"D-do you hear that?" Z-69 extinguished the filament. Darkness returned instantly.
"Yes," he said.
"And it isn't ours." One of Jin's traps clicked. Lightly. Barely a sound. In that silence, it was a shout. Jin rose before Ten could blink.
"West." Nothing charged. No roar. No dramatic leap. A shadow crossed the shelter entrance. Then vanished. Silent as a thought. Jin's jaw tightened.
"They're watching." Z-69 extended his awareness into the dark. The battles during daylight had dulled his senses, but not enough to erase the tiny air-pressure shifts, temperature changes, and redistributed weight passing across leaves and soil whenever something moved carefully enough to believe it had become invisible.
"They're testing us," he said.
"Learning how we react." Ten's voice became smaller.
"Toying with us?"
"Yes." Jin swallowed.
"So what do we do?" Z-69's answer was calm.
"We give them nothing repeatable." The first impact came without warning. Something struck the barricade hard enough to send vibration through the roots, then bounced away before the branches finished shaking. A second hit landed from another angle. Not random. Probing. Ten's hand touched the ground.
"Right—!" Z-69 pivoted and cut in a tight arc. The blade struck something solid. A shriek tore through the night—too thin to be an animal, too wet to be machinery. The creature withdrew before Jin's counterattack reached the opening.
"They're fast," Jin said.
"And disciplined." The probing stopped. No corpse remained. No blood trail. Only fresh claw marks placed at different heights and angles across the barricade. Data points carved by sharp fingers. Ten pressed harder against the soil. Sweat gathered on his forehead despite the cold.
"They're circling."
"How many?" Jin asked.
"I can't separate them. Too many small steps. Dozens, maybe more." Jin exhaled between his teeth.
"Great. A smart pack." The violet crystal pulsed once. Soft. The Hunger oriented toward the movement outside. Many. A brief pressure tightened beneath Z-69's sternum. Good. He ignored it.
"Stay close. Ten, read the ground and call directions. Jin, don't chase. They want us separated." Jin looked offended. Then looked at the darkness outside.
"Fine." Love this novel? Read it on Royal Road to ensure the author gets credit. Ten nodded quickly.
"O-okay." For several minutes, the forest only breathed around them. Then the second attack came from above. A shadow dropped through the canopy without sound and landed inside their perimeter as though it had always been there. Jin reacted on instinct. Too fast. Too direct. The creature feinted. A second shadow struck him from the blind side with brutal precision. Jin skidded through the metallic leaves and caught himself against a root.
"Left!" Ten shouted. Z-69 stepped between him and the attack without thinking. The first creature lunged. He caught its snapping jaws on the flat of his blade. The impact drove him half a step into the soil. Dense. Compact. Engineered. A restrained spark jumped from his grip and briefly revealed the attacker. A Night Reaver. It resembled a primate reconstructed by a machine that understood nightmares better than anatomy. Dark fur clung in patches to a rigid biometal exoskeleton.
Its arms were too long, ending in surgical claws. Shorter legs coiled beneath it for explosive leaps. The face combined an organic snout with an armored frame, while wet glass eyes reflected nothing kind. It stared at Z-69. Head tilted. Not confused. Evaluating. Jin forced himself upright and wiped blood from the corner of his mouth.
"Night Reavers." Ten tightened his grip around the worn low-output pistol John had entrusted to him.
"You know them?"
"Stories from the lower levels. Nocturnal pack predators. Individually, most aren't exceptional." Jin's gaze swept across the trees.
"The pack is. They bait, flank, pressure, and force mistakes. They don't hunt to kill quickly. They hunt until they solve you." A second Reaver emerged beyond the barricade. Then a third. More eyes appeared higher in the trees. Not charging. Not panicking. Waiting. Z-69 kept his own pistol holstered. A weaker shooter firing into a mobile pack would create more light than damage, and the Reavers were already studying movement.
"They're holding distance," he said.
"There is a leader."
"Or an Alpha," Jin replied. The Reaver before Z-69 backed away without turning. Not retreating. Repositioning. Then the pack moved. Not together. In layers. Two struck the barricade from the front to fix Z-69's attention. Another slipped beneath the roots toward Ten.
Jin intercepted with a speed burst, but his strike met empty air because the Reaver had expected the commitment and used it to pull him into a landing path already claimed by a fourth creature dropping from above with its claws aligned to the exact point his momentum would carry him. Jin twisted at the last instant, and the attack sliced through his sleeve instead of opening his spine.
"Bastards."
"Behind!" Ten shouted. Z-69 pivoted and cut. This time, the blade connected cleanly. The Reaver bled dark fluid across the soil. The rest of the pack changed immediately, showing no rage or panic as the circle widened, spacing shifted, and attack angles recalibrated around the reach and recovery time of Z-69's blade. Jin's eyes narrowed.
"They adapted."
"They learned what the weapon can do." Ten's breathing shortened.
"Then what now?" Z-69 lowered his stance.
"Now they stop playing." The Reavers disappeared into shadow. Ten kept one palm against the ground.
"They're still there. Everywhere. Barely moving."
"They're waiting," Jin said. Z-69 felt a heavier pressure shift among the trees. Something that did not need speed because the rest of the pack moved for it. Ten went pale.
"One is coming." His voice thinned.
"Big. The ground feels wrong." The Alpha stepped into view. It did not roar. It arrived. The silhouette stood almost as tall as Z-69 and carried far more mass through the shoulders. Its exoskeleton was thicker, its claws longer, and its fur matte-black enough to absorb what little light existed. Its eyes fixed on Z-69. Not afraid. Not curious. Certain. Predator recognizing predator. Jin swallowed.
"That is not the same rank as the others." The Alpha lowered its body. Muscle coiled beneath metal. Z-69 stepped forward. The creature exposed reinforced teeth. Z-69 bared his own. An old human gesture. Now hollow. For one second, they remained still. Then the Alpha attacked. It crossed the distance through explosive force rather than Jin's compressed speed, its dense body driven by reinforced joints and perfectly aligned muscle. The claws descended in a cross-slash aimed at Z-69's chest. He blocked. Barely.
Shock traveled through the blade, into his arms, and down his spine. Bone and metal complained together. The Alpha followed with a low sweep toward his legs. Z-69 jumped with minimal motion and landed one step back. It gave him no space. Claws cut through soil and metal roots with disciplined precision, nothing in its movement matching the feral shape wearing it.
"Left—two more!" Ten shouted. The pack surged to capitalize on the Alpha's pressure. Two Reavers attacked Z-69's flanks, attempting to pin his arms while the Alpha targeted the crystal. Jin flickered into one and smashed it in midair. The second passed him because it had wanted that exact commitment.
"Smart," Jin snarled.
"Too smart!" Z-69 cut down the flanker. The Alpha was already inside his range. A claw tore through his shoulder and caught against something harder beneath the corpse tissue. The impact opened his stance. Its other hand drove toward the violet crystal.
"Z-69!" He twisted just enough. The claw missed the crystal by a fraction and raked across his sternum instead. The core throbbed. The Hunger pressed upward. Let me. Z-69 forced it down. Not now. He answered with a tight slash toward the Alpha's throat. It leaned back by millimeters, then slammed its armored skull into his face. Z-69 staggered. Darkness thickened at the edge of his vision. Jin tried to rush in. Two Reavers intercepted him immediately—one above, one behind—forcing him to defend instead of assist.
Ten raised his pistol and fired along the path his predictive resonance insisted the first Reaver would occupy, striking the creature before its leap completed and forcing it sideways before sending a second bolt through another future angle that had not yet become visible to anyone else. Bright flashes strobed through the shelter. Claws suspended in the air. Jin sliding across leaves. The Alpha rotating toward Z-69. The shots were accurate. The light was still a mistake.
The Alpha moved each time the flash vanished, timing its attacks to the darkness between Ten's trigger pulls. Fear had become a metronome.
"Ten," Z-69 growled.
"Stop firing." Ten froze with the pistol half raised.
"But I can see where they're going—""They can hear when you decide to shoot." Ten understood. His finger left the trigger. Darkness settled without rhythm. The Alpha hesitated. Only half a second. Enough. Z-69 stepped into its range rather than away. The next claw passed beside his ribs and opened a shallow line through flesh. Acceptable. Position mattered more. He drove the blade toward its torso. The Alpha caught his wrist with one reinforced hand and twisted. The joint popped. The weapon nearly fell.
Z-69 released it deliberately. Jin's shout crossed the dark.
"What the hell are you—" Z-69 slammed his free hand into the Alpha's jaw, hooked his fingers beneath the metal reinforcement, and forced its mouth open. The creature thrashed. He leaned forward and used his whole body to hold it. Ten understood first.
"Jin—now!" Jin broke through the Reavers pressuring him with an elbow and a knee that caved one construct's chest. He flashed into the opening and drove a strike into the seam where exoskeleton met organic tissue. Fast. Precise. The Alpha howled. The pack reacted. Three Reavers lunged toward Jin. Ten moved before fear could stop him. He fired once. Not at the creatures. At the ground across their approach. The energy bolt burst into heat and light.
The Reavers recoiled from the sudden flare, their coordinated path breaking for one critical instant.
"Go!" Z-69 caught the fallen blade as though it had never left him and drove it through the Alpha's shoulder joint. The creature shrieked and slammed him down. He struck the ground hard enough to dent the metal beneath the soil. The impact split his back open. The violet crystal flooded the wound with repair energy. And appetite. Eat. Z-69 clenched his teeth until pressure cracked through his jaw. He forced himself present. The Alpha towered over him, chest heaving, eyes fixed upon the crystal. Both claws rose.
Z-69 rolled. The killing strike missed by less than a breath and gouged deep lines through the soil, exposing luminous root-metal beneath. He rose to one knee. His wristband flashed red. Regeneration was active. Not fast enough. The Alpha was built to kill regenerators through repeated high-impact trauma, deliberate core targeting, and the refusal to waste force on limbs when the creature already understood exactly where continuation lived inside Z-69's body. Ten's voice trembled, but remained clear.
"Its center vibrates differently. Under the sternum. There's a core." Z-69's eyes narrowed.
"Good." He stood. The Alpha charged low, intending to ram him upward, expose the violet crystal during the lift, and tear open his chest before gravity returned him to the ground, but Z-69 refused the defensive answer it had already calculated and stepped directly into the collision. For the first time that night, he permitted a narrow thread of Thunderlight to enter the blade. Not a flare. Not a storm. Only a controlled rejection filament.
The current burned backward through the hand conducting it, opening black fissures across his palm and toward the wrist while the violet crystal spent reserve repairing the self-inflicted damage almost as quickly as Thunderlight created it.
The blade met the Alpha's charge with enough force to make metal scream through the forest, and Z-69 slid backward with his heels carving trenches through the soil while every damaged joint in his body fought to preserve the angle needed to redirect the creature's momentum downward rather than absorb it. Then he drove the blade through its sternum. The instant the edge reached the core, Thunderlight surged inward. Not outward. No spectacle. No wasted arc.
The rejection current entered the construct's internal energy pattern and violently denied the arrangement keeping it coherent. The Alpha convulsed. Its scream stopped sounding organic. It became the noise of a machine discovering that it could die. Z-69 held the weapon in place, jaw locked, while the black cracks along his hand spread another centimeter. The crystal spent reserve closing them as quickly as Thunderlight opened them. The Alpha's claws weakened. Its legs buckled. It collapsed like a wrecked engine.
Silence struck the forest. Heavy. Immediate. The remaining Night Reavers froze and compared the collapsed Alpha against the wounded figure still holding the blade, displaying no panic, grief, or rage before calculation passed through the pack and sent them withdrawing one by one—not because they feared Z-69, but because continuing would waste bodies without improving the odds. Ten dropped to the ground as if someone had removed his bones.
A small laugh escaped him, broken, disbelieving before becoming a shaky exhale.
"We… survived." Jin leaned against a trunk, breathing hard.
"That was too close." Z-69 stood over the Alpha. His flesh closed in ugly increments. The cracks created by Thunderlight had already begun sealing, but the wristband remained orange-red. His eyes were clear. Behind his sternum, The Hunger scraped patiently against its boundary. Food. Ten looked between the corpse and Z-69.
"It's dead, right?" Z-69 knelt beside the Alpha, pressed two fingers against the still-warm sternum plating to read the final vibration beneath it, and cut through the seam with the controlled precision of a field surgeon operating on something that had already crossed the line from enemy to supplies. No theatrics. No savage tearing. Field dressing. Jin's expression tightened.
"You're seriously going to—""We are inside a twenty-four-hour survival trial with no stable food source and no safe water. Night is designed to exhaust us." His tone remained simple.
"This is what you do with a kill in the wild." Ten swallowed. He did not look away. Z-69 reached inside and removed the Alpha's energy core. Compact. Dense. Almost organic. A crystalline organ pulsing faintly with Tower-made vitality rather than Prime Flux. The Hunger leaned toward the pulsing organ with immediate recognition, but Z-69 retained control long enough to study the foreign vitality, choose necessity over frenzy, and swallow the core whole before appetite could claim the decision as its own.
Jin gagged on reflex.
"That is disgusting."
"Efficient." Warmth spread through Z-69's limbs. The foreign energy entered the violet crystal reluctantly, carrying none of the metallic contamination of ordinary Flux and none of the familiarity of living vitality, forcing the core to process a Tower-made substance it could neither recognize nor fully reject. Not cleanly. Enough. The torn flesh across his back tightened. His wristband moved from red toward orange. Ten stared.
"It healed you."
"It restored energy. The crystal performed the healing." Z-69 looked down at the carcass.
"This ecosystem converts survival into currency. An Alpha carries more." Then he began to butcher it. Not all of it. Only enough. He cut thick strips from areas that appeared least human. Away from the face. Away from the hands. Away from anything that might turn survival into an image Ten could not swallow. His movements were grim and practical, the motions of a soldier taking rations from the only source the battlefield had provided. Ten's stomach growled. A betrayal loud enough for both others to hear.
Jin smirked despite himself.
"Kid, you're starving."
"I'm not—" Ten stopped. Ashamed. Z-69 gathered dry metallic leaves and shaped a shallow heat pit beneath the roots. A tightly controlled electric spark activated the leaf-veins without producing open flame. No beacon. Only concealed heat. A survival fire, not a campfire. He placed the meat across the heated leaves. Fat hissed softly. The smell rose. Sharp. Rich. Uncomfortably real. Ten's throat moved. Jin looked away.
"It looks too close to human." Z-69 did not argue. He continued cooking. Minutes passed. The forest remained quiet. Too quiet. Eyes glimmered between the trunks. The pack watched their dead Alpha become fuel but did not attack. Not yet. They had lost the strongest body in their formation. They would not waste the rest in blind anger. They would remember. Z-69 handed the first cooked strip to Ten. Ten hesitated.
"You fought," Z-69 said.
"You called angles. You created the opening." Ten looked up.
"That means you eat." His hands shook when he accepted it. He bit down. His face twisted, not only from the taste, but from the idea of what he was doing. Then heat and protein reached his empty stomach like medicine. His shoulders loosened slightly. Jin watched for several seconds, jaw working, before snatching a strip from the heated leaves.
"If I die from whatever disease that thing had, I'm haunting you." Z-69 produced a near-invisible smirk.
"Noted." They ate in silence, sharing neither comfort nor peace, only the temporary understanding that refusing the meal would not make the Alpha less dead, the forest less hostile, or the remaining hours of night more survivable. Beyond the barricade, faint eyes continued to watch. Ten tightened his grip around his pistol.
"They're still there." Z-69 did not look up.
"Let them watch."
"They'll come back," Jin said.
"Yes." Z-69 lifted the Heaven-Sundering Short Blade. A faint violet line lingered along its edge, barely visible and already paid for in black fractures beneath his closing skin. His compact pistol remained ready at his hip. Ten held the separate weapon John had entrusted to him. Jin adjusted his legs, prepared to move despite sitting.
The forest was not retreating, it was thinking, recalculating, and preserving the pack for another attempt after fatigue had weakened the three survivors more thoroughly than claws could manage in a single charge. And night had only just begun.
