Cold was not merely the absence of heat.

  In Sector Seven, on the banks of the Foggy Reach, cold was a tangible entity—a heavy, slick shroud that seeped into the pores and drained whatever life remained. The river fully lived up to its name: a dense gray suspension hung motionless above the water, reeking of rotting pine needles, wet stone, and that distinct metallic tang that always accompanied a high concentration of mana.

  I lay in the silt, my face slowly sinking into the black sludge. My left arm, which had taken the brunt of the impact against the rock outcrop during the fall, felt like a foreign object. It wasn’t just pain—it was broadcasting white noise straight into my brain, pierced by the unmistakable grinding of bone fragments with every breath I took. The shoulder joint was shattered; I could feel the jagged edges of my scapula biting into soft tissue from the inside, triggering localized hemorrhaging.

  [The Will to Live] inside my head did not sympathize.

  It functioned like a malfunctioning onboard computer of a crashing aircraft. Its “voice”—if that steady pressure against my temples could be called a voice—methodically read out a list of failures.

  “Warning. Left shoulder critically damaged. Deltoid muscle torn. Body cooling—hypothermia. Brain functions slowed. Without warmth, survival is almost impossible.”

  “Shut up…” I rasped.

  The sound of my own voice felt alien, like a dry branch snapping underwater.

  I tried to move my right hand. The mud beneath my fingernails burned like red?hot coals. I needed heat.

  Magic, as I understood it, was never a miracle. It was work with entropy—a manipulation of system efficiency, where the fuel was my own body.

  I reached for the nearest boulder. A slab of granite, half submerged in icy water, slick with moss. The task was simple from a physics standpoint—and horrific from a biological one. I needed to create a localized thermodynamic imbalance.

  I closed my eyes, focusing on the stone’s molecular lattice. Mana wasn’t sparks from fingers—it was a force vector. I forcibly accelerated molecular motion inside the granite, increasing collision frequency, generating kinetic energy that immediately converted into heat.

  But the law of energy conservation was merciless. I couldn’t pull heat from nothing. I was acting as a heat pump.

  My right arm—healthy until that moment—seized with violent convulsions. Frost instantly crept across the skin of my forearm. To heat the stone to forty degrees, I had chilled my own arm almost to zero. The muscles locked, fingers clamping around the granite, while the skin began to crack from flash dehydration.

  “Come on… just a bit more…”

  My teeth chattered uncontrollably.

  The stone began to glow in the thermal spectrum, which I could now perceive thanks to the skill. I pressed the heated rock to my chest, directly over my heart. The burn was a blessing—it meant I was still alive. Warmed blood surged toward the aorta, restoring clarity to my consciousness.

  This was my external battery—purchased at the cost of frostbite to my right arm.

  But in this world, every action demanded payment—twice.

  My thermal anomaly in the frozen fog shone to the Order’s tracking artifacts like a flare.

  From above, from the edge of the cliff, came a sharp, piercing whistle.

  It wasn’t human.

  That was the sound of Whistlers—acoustic sensors released by Order rangers. They reacted to fluctuations in air density and thermal irregularities.

  “Tracking signal detected. Distance to source: 150 meters. Probability of visual contact within 180 seconds: 99%.”

  I tried to stand. My left leg—slashed open by Kyle in the wagon—refused to bear weight. The wound Zeno had sealed reopened; I felt warm blood rapidly being washed away by the river’s icy water.

  “[The Will to Live]…”

  I gasped, slumping against the wet trunk of a fallen tree.

  “Disable… limiters. Reroute energy… from digestive organs… to the locomotor system.”

  The skill responded with an immediate spasm in my abdomen. My stomach twisted into a knot—the body initiated emergency resource dumping into the leg muscles.

  Biomechanical overdrive.

  My heart went berserk—160, 180 beats per minute. The arteries in my temples pulsed so hard my vision tunneled.

  I stood.

  The world swayed like the deck of a sinking ship. My shoulder hung useless, but I moved, leaning on a broken pine branch. Every step came with a rasping wheeze. I wasn’t just walking—I was calculating the vector of every movement to minimize stress on shattered bones.

  Pure survival mathematics.

  No hope involved.

  I covered a hundred meters. The fog ahead thickened further. The Dead Marshes loomed—a vast lowland saturated with methane and rot. If I reached them, I could exploit the temperature gradient to create a thermal veil and break pursuit.

  Methane is flammable.

  And if I could induce a localized resonance…

  Crunch.

  Behind me. Close. Not on the road—here, on the riverbank.

  I froze, barely breathing. Slowly, fighting vertigo, I turned.

  A silhouette drifted from the gray wall of fog thirty paces away.

  Not Kyle. Not some idiot guard.

  A Fifth Circle Ranger.

  A professional defect hunter.

  Gray leather armor etched with stealth runes blurred him into the fog. In his hands rested a heavy crossbow with limbs made of black composite.

  On his shoulder perched an Eye—a mechanical raven whose lenses rotated with dry clicks. A red scanning beam swept over my body, paused on the heated stone at my chest, and locked.

  The Ranger said nothing.

  To him, I wasn’t human.

  I was an extraction—or termination—protocol.

  He began to raise the crossbow.

  Distance: twenty?five meters.

  Given humidity and fog density, bolt trajectory predictability: 96%.

  I couldn’t dodge.

  My body was too slow.

  I had to change the environment.

  I was still gripping the stone in my right hand. It was cooling, transferring energy into my body, but residual vibrational potential remained.

  “If I instantly convert the stone’s heat into motion, success is unlikely. Getting a thermal shock, though—that’s almost certain.”

  “Do it…” I exhaled.

  I focused everything on the stone. I didn’t need to throw it. I needed sudden thermal expansion.

  According to thermodynamics, if I rapidly increased volume inside a closed crystalline lattice, the stone would simply detonate—shattering into shrapnel.

  But I wanted more.

  I wanted direction.

  The Ranger’s finger settled on the trigger. Time didn’t slow—my brain, driven beyond biological limits by the skill, began processing visual data at an impossible frequency.

  I saw the bowstring tighten.

  The fibers of his glove compress under steel pressure.

  I didn’t wait.

  I slammed my will into the stone’s molecular structure.

  It wasn’t an explosion in the conventional sense.

  It was a phase transition.

  I instantly converted residual heat into lattice expansion energy. The stone ceased to exist as a unified object—becoming a cloud of superheated sand and razor?sharp fragments.

  And I didn’t just detonate it.

  I used my right palm as a nozzle, vectoring the expansion toward the Ranger.

  The cost was predictable.

  Skin tore free along with the upper muscle layer. It felt like plunging my hand into an industrial blender.

  The blast of incandescent stone fragments surged forward at the exact moment the crossbow bolt left the rail.

  They collided five meters from me.

  The heavy steel bolt tore into the dense granite cloud. Physics was unforgiving—the bolt’s momentum partially dissipated against the mass of fragments, its trajectory wobbling.

  It passed a centimeter from my neck, narrowly missing the carotid artery, and slammed wetly into the tree behind me.

  The Ranger was less fortunate.

  He hadn’t expected a “barehanded defect” to fire a superheated boulder.

  Stone shrapnel ripped into his Eye—the mechanical raven shattered, spraying sparks and lens fragments across his face. The Ranger staggered, hand instinctively rising to his eyes.

  That gave me the three seconds I didn’t have.

  “Run…”

  The skill rasped inside my skull—not a calculation now, but an animal command.

  I turned and bolted toward the Dead Marshes.

  My flayed right hand burned so intensely I nearly blacked out. Blood sprayed from the palm, leaving a smoking trail across gray stones. My wounded leg dragged, but [The Will to Live] kept pumping obscene amounts of adrenaline into my muscles, driving my heart toward collapse.

  I burst into the Marshes as the fog thickened until I couldn’t see my own fingers. Black, oily sludge sucked at my boots. The methane stench was so strong it made me dizzy.

  This was my final line.

  The Ranger followed. I heard his steps—heavy, confident. He no longer hid. He was angry.

  The dry click of a reloading crossbow cut through the marsh silence.

  I needed to exploit a pressure gradient.

  Methane pooled in lowlands, forming invisible gas lenses. If I ignited the right spot, I could trigger a volumetric explosion that would consume all oxygen within twenty meters.

  The problem was—I was at the center.

  “Methane in the air—an explosive mix. Triggering the resonance will ignite it for sure. Survival chances? Slim to none.”

  “Calculate…”

  I dropped to my knees in the rot, feeling the sludge pull me down.

  “Calculate blast vector… using fog density…”

  I concentrated energy into the fingertips of my ruined hand. I didn’t need fire. I needed high?frequency air resonance—enough to spark.

  This was suicide.

  I was turning myself into a detonator.

  The Ranger emerged from the fog ten steps away. Blood streamed from his shattered brow, his face a demonic mask. He raised the crossbow, aiming at my chest.

  “End… connection…” I whispered.

  I slammed my palm into the water, releasing an ultrasonic pulse into the oily surface.

  The world stopped being gray.

  It turned orange.

  The explosion wasn’t loud—methane in fog detonates with a deep, guttural roar. A fireball bloomed instantly, devouring oxygen and flash?boiling the mist into superheated steam.

  The Ranger was simply erased—his scream cut off as the blast hurled him back into the river.

  What saved me was the very sludge I’d submerged myself in seconds before ignition. I used water as a thermal shield.

  The burns across my back were nothing compared to what I felt when the explosion sucked all air from my lungs. Vacuum crushed my chest; capillaries burst behind my eyes.

  I lay in boiling filth while fire raged above me.

  It vanished as quickly as it came, leaving scorched emptiness and the stench of burned flesh.

  I was alive.

  My hair was charred. The skin on my back had fused into a single blistered crust. My right hand felt nothing at all.

  But I was alive.

  [The Will to Live] issued its final report for the day:

  “Core temperature: 35.8°C. Critical depletion of magical channels. Motor function failure in 120 seconds. Recommendation… sleep.”

  “Sleep…”

  I wheezed, choking on black water.

  “You sleep… tin can.”

  I crawled deeper into the Marshes—into the true fog, where no Ranger would dare enter without heavy protection. I left behind a furrow of mud mixed with blood and ash.

  I didn’t win.

  I simply refused to die on the Order’s terms.

  I vanished into the fog just as the first riders on scaled mounts reached the shore. They saw only a scorched crater and an empty river.

  I became a ghost.

  A defect who knows how to turn the laws of physics into weapons—using his own agony as fuel.
