Chapter 53: Mana Recovery

Rain’s feet dragged through the slick, dark silt lining the floor of the descending conduit. Every step was a heavy, deliberate struggle against his own failing body. His breath came in shallow, wheezing hitches that burned like hot needles deep in his chest. His ribs, throbbing from the Rustjaw’s tail strike, felt loose, grating together beneath his bruised skin whenever his weight shifted awkwardly.

He had no weapon. He had no armor. His dark hoodie was shredded at the shoulder, soaked through with a mixture of his own blood, grey leech fluid, and the black, oily grease of the Gravewright.

His vision swam with dark, flickering spots.

’At Intelligence twenty-one, resting fully, I regen a point roughly every forty-some minutes,’ Rain thought, doing the math against what the system had confirmed to him weeks ago. ’Active, moving, fighting, that stretches out even further. I’m not resting. I’m not going to get a single point back on my own before something else finds me.’

He leaned heavily against the wet concrete wall, his shoulder smearing a streak of grime down the stone as he slid half an inch.

He stared down at his trembling right hand. His knuckles were raw, the skin split down to the bone in two places from driving his fist into the Gravewright’s face seam.

The blood had stopped flowing freely, but the wounds weren’t closing.

Rain thought back to the White Tiger hospital stay after his first rift dive, how baffled the healers had reportedly been running scan after scan, unable to explain how his bone fractures had knit together in under days. He’d had a full Mana pool then, resting in a bed with nothing to spend it on, his regen ticking away undisturbed for days. He’d assumed at the time it was just his body being strange.

Now, staring at his status panel hovering at twenty-five health, the truth clicked into place with cruel, agonizing clarity.

Whatever the system did for his body ran on Mana. When his pool was full and idle, that same energy seemed to spill over into stitching him back together, faster than anything ordinary. It wasn’t a lifelong trait. It had only ever shown up since the day the system activated inside him.

Right now, his mana was at zero. Completely dry.

’And zero mana,’ Rain thought, ’apparently means zero healing too.’

From deeper down the sloping conduit, the low, rhythmic vibration hummed through the concrete floorboards. It was louder now, a heavy, bass-frequency thrumming that rattled the loose gravel around his boots.

Rain forced his legs forward. He dragged his right foot, using his left arm to brace against the concrete wall, inching down the pitch-black tunnel. He had no choice. Standing still meant bleeding out in the dark while whatever was generating that vibration tore through the lower levels.

The conduit curved sharply to the left, opening into a broad, high-ceilinged pumping station. Rusted iron catwalks hung suspended twenty feet overhead, half-collapsed and swaying gently in the cold draft blowing up from the lower depths.

Rain rounded the concrete corner, his shoulder scraping against the rough edge of the wall.

He froze.

The air in the pumping station was dead silent, save for the heavy, rhythmic thrumming echoing from the floorboards below.

Standing twenty paces ahead, evenly spaced across the wide, flooded floor of the chamber, were three figures.

They were tall, gaunt, and impossibly narrow, constructed from long, bleached animal bones bound together by thick, intertwining strands of blackened root fiber. Their elongated, smooth bone heads lacked eyes, ears, and noses.

They were three Gravewrights.

The moment Rain’s boot touched the shallow water at the entrance of the chamber, all three featureless white face plates snapped toward him simultaneously.

A wall of harsh, deep red system text exploded directly before Rain’s eyes, the crimson glow casting long, jagged shadows across the flooded concrete.

[Multiple Targets Identified: Gravewright (x3)]

[Rank: D-Rank (High) - Group Encounter]

[Type: Beast / Drain Predator]

[Attributes: Mana Drain on Contact, Reinforced Frame]

[Threat Level: Lethal]

Rain’s heart slammed against his shattered ribs like a sledgehammer.

’Lethal,’ his mind screamed. ’Not severe. Lethal.’

The three gaunt abominations stepped forward in unison. Their jointed, skeletal legs moved with that same unhurried, clockwork precision, their four horn-like fingers twitching as the vertical seams in their smooth face plates split open simultaneously, revealing the dark, hungry cavities inside.

Rain didn’t think. He didn’t evaluate.

Panic, raw and unadulterated, swept through his chest like a tidal wave. He stumbled backward, throwing his weight around the concrete corner, and collapsed against the wall of the narrow conduit he had just exited.

He slid down the stone until his rear hit the cold, wet floorboards, his knees pulled tight against his chest, his hands pressing hard against his face.

His breath came in wild, ragged gasps that sounded pathetic in the narrow tunnel.

’I can’t do this,’ Rain thought, his mind spiraling out of control as the darkness pressed in from all sides. ’I’m at twenty-five health. Zero mana. I can barely hold my own arm up. One of those things almost killed me when I had fuller health and eleven mana. Three of them? Three?’

A cold, heavy darkness settled over his thoughts, bringing up memories he had spent months trying to bury.

He remembered the afternoon of the Resonance Ceremony clearly, the brass booth, the scanner reading the Core behind his sternum, the flat, unimpressed tone of the technician reading his result off a slip of paper. F-rank. A disk that turned out to be worth less than the plastic case it came in.

He remembered Sen too, that same morning, a stranger he’d never see again after that day, shoving his own disk case into Rain’s arms in a moment of pure desperation before running, calling nothing back except his own name breaking apart in the crowd. Sen hadn’t looked down on him. Sen had looked like someone who’d already decided there was nothing left worth staying for.

’Maybe he had the right idea,’ the dark voice in his head whispered, heavy and suffocating. ’Maybe I’m just a carrier who got lucky with a weird system glitch. I’m an eighteen-year-old orphan with no gear, no backing, no sword. I’m sitting in three inches of sewer water bleeding to death because I thought I could act like a hunter. I’m going to die right here, and tomorrow morning Holt will sign a form saying the carrier went missing in action, and nobody will even remember my name.’

The cold silence of the tunnel stretched out. The rhythmic thrumming from the floor below continued its steady beat.

The sound of skeletal feet clicking against the stone outside the corner drew closer.

Rain stared at the black water pooling between his boots. The reflection of his own blue eyes stared back at him from the murky surface, pale, bloodshot, but undeniably bright in the gloom.

Something shifted in his stomach. A glimmer of something that made him feel almost disgusted by his own thoughts.

It wasn’t a sudden burst of heroic light or a heroic revelation. It was a sharp, ugly flare of pure, unadulterated anger.

’No,’ Rain thought, the dark, defeatist voice in his head suddenly cut short by the sheer, hot spike of fury rising through his chest. ’Or maybe that’s just what the whole damn system wants.’

He squeezed his fists, feeling the split skin on his knuckles stretch and sting.

’It wants me to lie down right here. Holt wants me to carry his extra gear until my back snaps. The academy sorted me into the bottom of Class C and expects me to stay there quietly.’

A short, breathy, half-mad snicker burst from Rain’s throat. It echoed off the narrow concrete walls, a sharp, ragged sound that sounded more dangerous than afraid.

"Nice try," Rain muttered out loud to the empty dark.

He pressed his back hard against the concrete wall behind him, his eyes locking onto the corner of the conduit where the three Gravewrights were advancing.

He had no plan. He had zero mana. He had twenty-five health. He was completely, utterly cornered.

His right hand twitched, sliding down his side as he tried to shift his weight to get a better angle against the wall. As his hand moved, his elbow brushed against the heavy, bulged pocket of his dark hoodie.

The faint, dull sound of hard, crystalline spheres knocking together inside the fabric echoed softly in the quiet tunnel.

Rain stopped.

He reached down with his uninjured right hand, dipping his fingers into the deep front pocket of his hoodie. He pulled out four cold, smooth, translucent spheres, followed by three larger, rougher ones that weighed down his palm.

Monster cores.

Since the moment the floor had collapsed beneath the silo, Rain had been harvesting every single core from the creatures he killed. He had no pouch, no gear bag, no storage. Every time he crushed a monster’s skull or chest, his fingers had automatically reached for the central core, digging it out of the rotting meat and slipping it straight into his hoodie pocket.

He hadn’t even thought about it at the time. It was an instinct drilled into him during his last raid as a carrier. In the lower districts, you didn’t leave money lying in the mud. Even if he was trapped in a hidden rift, he felt he was owed some form of personal compensation for almost being killed ten times over, and gathering cores along the way was the only tangible value he could claim.

He held the seven cores in his bloody palm, staring at them in the dim ambient light.

Four small, pale grey spheres from the Pallid Crawlers.

One thick, rubbery, deep-green sphere from the Sump Leech.

One heavy, metallic-toned, dark reddish sphere from the Rustjaw.

And one large, pulsing, violet-tinted sphere from the Gravewright he had just destroyed.

Rain’s mind, sharp and analytical even through the fog of pain, suddenly locked onto the system interface hovering in his peripheral vision.

’System,’ Rain thought, his intent sharp and urgent. ’What’s the command to convert harvested physical assets into monetary value?’

The blue interface flickered, a clean, concise text box opening over his palm.

[Function Identified: Direct Material Liquidation / Sell Catalog]

[Place physical assets into the direct interface field or designate inventory items for valuation.]

Rain stared at the text. A sudden, desperate surge of realization hit him so hard his breath caught in his throat.

’The system has a store,’ Rain realized, his mind racing at lightspeed. ’It has a store, which means it has an exchange interface. I don’t need a trade merchant in the central district. I don’t need an official guild appraiser.’

He focused his mind directly on the seven cores resting in his palm, willing them into the system’s liquidation field.

A pale blue beam of light swept over his hand, scanning the crystalline spheres one by one.

[Item: Pallid Crawler Core (F-Rank) x4]

[Valuation: 8 SC each]

[Subtotal: 32 SC]

[Item: Sump Leech Core (D-Rank)]

[Valuation: 35 SC]

[Item: Rustjaw Core (D-Rank)]

[Valuation: 60 SC]

[Item: Gravewright Core (D-Rank High)]

[Valuation: 95 SC]

[Total Liquidation Value: 222 SC]

[Execute Sale? (Y/N)]

Rain stared at the numbers hovering over his palm.

’Ninety-five credits for the Gravewright,’ Rain noted, his eyes widening slightly as he processed the steep scaling. ’The F-rank crawler cores are only worth eight. The jump from F-rank to high D-rank isn’t linear, it’s an exponential curve. A single high D-rank core is worth more than ten F-rank cores combined.’

’Execute,’ Rain commanded mentally.

The seven spheres in his palm dissolved into tiny, brilliant specks of blue light, vanishing into thin air as if they had never existed.

A sharp chime rang out in his mind.

[Transaction Complete]

[Synthesis Credits Added: +222 SC]

[Current SC Balance: 222 SC]

Rain didn’t waste a single millisecond celebrating. With a thought, he summoned the Fixed Catalog interface, his mind rapidly scanning down the list of available items and their exact prices.

[SYSTEM STORE - FIXED CATALOG]

* Minor Mana Recovery Potion (Rank F) — 50 SC

Restores 5 Mana instantly upon consumption.

* Standard Health Salve (Rank F) — 40 SC

Accelerates natural healing of physical trauma over 30 minutes.

* Hardened Ridgeback Plate Vambrace (Rank D) — 220 SC

Provides structural forearm protection against physical bludgeoning and low-tier piercing attacks.

* Bonewretch-Bone Reinforced Blade (Rank D) — 260 SC

D-rank melee weapon. High durability, sharp edge.

Rain’s mind analyzed the four options with ruthless, objective speed.

’The Vambrace is two hundred and twenty credits,’ Rain thought, evaluating the armor piece. ’I have two hundred and twenty-two. I could buy it right now. But what does forearm protection do against three Gravewrights? Nothing. They don’t deal slashing damage, their main threat is mana drain on contact. A piece of plate on my arm just gives them more surface area to grab.’

His eyes dropped to the second option.

’The Health Salve is forty credits. It accelerates healing over thirty minutes. Thirty minutes! I’ll be dead in thirty seconds if those three things step around this corner. I don’t have thirty minutes to sit in a corner and wait for skin to stitch itself together.’

His gaze locked onto the top entry.

’Minor Mana Recovery Potion. Fifty credits. Restores five mana instantly.’

Rain’s breath hitched in his throat as the pieces connected in his mind.

’Five mana instantly. My mana pool is at zero. If I drink one potion, my mana jumps to five immediately. That’s enough to cast Zero Drag. But more importantly.’

He remembered the White Tiger hospital stay.

’The moment my core has mana, my natural healing kickstarts itself. The passive core circulation turns back on. My HP won’t be frozen at twenty-five anymore.’

He did the math in his head instantly.

Four Minor Mana Recovery Potions at 50 SC each equaled 200 SC total.

222 SC minus 200 SC left exactly 22 SC remaining in his balance.

’Buy four Minor Mana Recovery Potions,’ Rain commanded mentally.

[Transaction Confirmed]

[Synthesis Credits Spent: -200 SC]

[Remaining Balance: 22 SC]

[Items Delivered to Primary Hand]

A small, heavy glass vial materialized out of thin air directly into Rain’s right hand, followed by three identical vials that materialized inside the front pocket of his dark hoodie.

The vial in his hand was roughly the size of a thumb, made of thick, frosted glass sealed with a simple wooden stopper. Inside, a brilliant, neon-blue liquid swirled and hummed with a faint, visible light.

Compared to the terrifying, life-or-death panic he had felt two minutes ago, the tiny glass bottle felt impossibly small, quiet, and almost anticlimactic.

Rain popped the wooden stopper off with his thumb and drank the contents in a single, desperate gulp.

The liquid tasted like bitter ice, cold copper, and ozone or to simply put...like shit.

The moment the fluid hit his tongue, a sudden, blinding rush of pure, arctic energy exploded outward from his throat, driving straight down into the center of his chest.

His core, which had been dry, hollow, and dark, flared back to life like a furnace being hit with a bucket of pure oxygen. A brilliant, blue-white light pulsed beneath his skin, radiating outward through his shoulders, down his arms, and straight into his bruised ribs.
