The low, subterranean silence of the lower annex was broken only by the crackle of dying embers, the faint hiss of cooling iron, and the rhythmic, hollow crunch of scorched crust flaking off raw metal.
Railin stood alone amidst the dense, swirling fog of grey smoke. His right hand remained pressed flat against the inner wall of the massive iron cauldron. Where a thick, toxic layer of alchemy slag had once clung like blackened dragon scales, there was now only a smooth, reflective sheet of silver-grey iron and a small heap of inert, bone-white ash resting on the damp floor.
He drew his hand back slowly, flexing his fingers, and looked down at his palm. The searing heat radiating from the furnace metal had left no burn marks on his skin. Instead, a faint, translucent sheen—a subtle byproduct of his soul cultivation—covered his palm like a protective glove. Deep within his chest, the ruined, crisscrossing maze of his broken meridians throbbed with a dull, unfamiliar warmth.
The Ashen Devouring Qi was not merely absorbing the lingering spirit energy hidden within the burnt residue; it was using that chaotic, unrefined strength to bind and mend the micro-fractures in his physical frame. His bone density was subtly increasing, his tendons tightening like pulled bowstrings, and his skin becoming tougher.
If three hours of devouring discarded garbage can fortify my body this much, Railin thought, his dark gaze sweeping across the dozens of uncleaned cauldrons sitting silently in the dim, cavernous chamber, what will happen once I process the entire lower annex? What will happen when I devour every failed scrap this academy throws away?
He moved slowly to the second cauldron. This one was even larger than the first, an ancient piece of black iron used exclusively by the inner disciples to refine lower-grade Spirit Gathering Pills. The residue left behind here was noticeably different—dark green, thick, sticky, and emitting a sickeningly sweet odor that carried a harsh, volatile sting.
To an ordinary labor servant without cultivation, touching this green crust with bare hands would mean instant skin corrosion. Breathing the fumes swirling inside the belly of the vessel for more than a few minutes would permanently rot the lining of their throat and lungs.
Railin did not hesitate for a single second. He stepped up to the edge, reached out, and pressed both palms firmly against the hardened, toxic green crust.
BZZZZ...
The moment his skin made contact with the residue, a violent burst of volatile, unrefined energy surged against his palms, attempting to burn through his flesh and melt his skin. The toxic green residue fought back like a trapped beast, its chaotic spirit energy lashing out in tiny, invisible needles of volatile heat.
Railin's eyes snapped open, two pitch-black pools glowing with cold, ruthless arrogance.
"Devour."
He summoned the dark embers from the depths of his dantian. The Ashen Devouring Qi responded instantly, rushing up his arm passages like dark mercury and coiling around his hands like invisible serpents. The black energy sank deep into the green crust, tearing its chaotic, molecular structure apart with brutal force. The volatile toxins were violently stripped away, neutralized into harmless grey powder, while the remnant essence of spiritual grass—condensed under high furnace heat—was forcefully extracted and dragged directly into Railin's body.
A surge of pure, refined energy flooded his soul space.
Railin gasped softly as his soul cultivation absorbed the sudden influx. The faint, phantom image of his soul sitting in meditation within his consciousness grew clearer, casting a soft, dark halo over his inner world. With every breath he took, his senses sharpened to an extraordinary degree. He could hear the faint scuttling of stone beetles three chambers away behind solid granite; he could feel the subtle shifts in room temperature as hot air escaped through the iron ceiling flues.
Minutes bled into hours inside the dark annex.
Railin moved from cauldron to cauldron like a silent, tireless phantom. He did not scrape with heavy tools, he did not scrub with harsh chemicals, and he did not touch the heavy iron chisels Overseer Lin had tossed at his feet. He simply touched, devoured, and moved on—leaving behind spotless, polished iron and small mounds of inert, snow-white dust.
By the time he reached the tenth cauldron near the far corner of the chamber, he noticed something peculiar buried deep within the thick, scorched crust near the bottom drainage flue.
Unlike the other waste, which was entirely burnt to a crisp, there was a hardened, semi-translucent lump stuck deep inside an iron crevice. It was the size of a pigeon's egg, dark red, rough-textured, and completely coated in black soot.
Railin knelt down, his dark eyes narrowing, and pried the object loose with his fingers.
Holding it up to the faint glow of the lingering furnace embers, a cold glint flashed across his eyes.
A failed pill core.
During the volatile process of alchemy, when an amateur cultivator fails to control the furnace flame at a critical juncture, the outer layer of the pill incinerates into slag. However, on rare occasions, the central core solidifies into a concentrated, dense mass of unrefined herb essence. The academy's alchemists routinely threw these away because the impurity levels were far too high for standard methods to cleanse, making them completely lethal for normal cultivators to consume.
"Lethal to them," Railin muttered into the silence, his raspy voice dripping with quiet irony, "but pure raw material for me."
He closed his fingers tightly around the hardened red sphere. Instead of instantly devouring it with his Qi, he paused. His mind worked with calculating precision, analyzing the exact internal structure of the failed core through his enhanced soul sense.
He could clearly feel the individual, conflicting components bound within the lump: remnant Blood-Nourishing Grass, crushed Spirit Stone powder, and a heavy, dangerous concentration of toxic Iron-Bark root.
The alchemist who attempted this batch failed because they applied too much raw heat during the fusion phase, scorching the outer shell before the Iron-Bark root could properly dissolve and synthesize, Railin analyzed, his eyes tracking the dark veins of energy inside the pill. If I use my Ashen Devouring Qi to strip away the scorched outer crust and forcefully neutralize the Iron-Bark toxins... I can isolate the pure Blood-Nourishing essence trapped inside.
This was alchemy in its rawest, most primitive form. Not through a grand furnace, not through precious spirit firewood, and not through high-grade cauldrons, but through the direct, precise manipulation of dark energy using his own body as the crucible.
Railin sat down cross-legged on the cold stone floor, resting the soot-covered pill core between his open palms. He closed his eyes, cleared his mind of all distractions, and began channeling a microscopic thread of dark Qi directly into the sphere.
Tsssk...
A faint plume of acrid black smoke rose from between his hands. The outer, burnt crust of the pill core began to dissolve into fine dust. Then, with surgical, breathtaking precision, Railin used his heightened soul sense to guide his dark Qi, seeking out the bitter, poisonous green threads of the Iron-Bark toxin coiled around the core.
The process demanded absolute concentration. A single slip of his dark energy would devour the beneficial Blood-Nourishing essence right along with the poison, destroying the pill core completely and rendering it useless.
Drops of cold sweat beaded on Railin's forehead, trickling down his jawline and splashing silently onto the stone floor. His broken meridians throbbed in dull protest as the dark energy circulated outside its normal pathways, but his soul remained absolute—cold, focused, and steady as frozen iron.
Ten minutes passed. Twenty minutes. Half an hour.
Pfft.
A tiny puff of foul, grey smoke flared out from his hands, carrying away the very last trace of impurity into the air.
Railin opened his hands slowly.
Lying in the center of his palm was no longer a rough, soot-covered chunk of garbage, but a small, smooth, deep-crimson bead. It had no blinding shine, no grand spiritual light, and no sweet fragrance like the high-grade pills sold to inner disciples on the upper peaks. But it was completely, undeniably free of toxins. It contained pure, concentrated, raw vital blood energy.
A crude, self-refined Blood-Refine Bead.
Railin stared down at the crimson bead resting in his hand for a long moment. A quiet, terrifying revelation settled deep into his heart.
The arrogant upper peaks of the Cultivation Academy treated the lower labor quarters as nothing more than a trash pit for their waste. They dumped hundreds of pounds of failed pill cores, burnt residue, and discarded herb scraps down here every single week without a second thought. To the sect leaders and elders, it was useless filth.
To Railin, this dark, subterranean annex was not a prison—it was an endless, untapped goldmine.
Without a moment's hesitation, Railin popped the crimson bead into his mouth and swallowed it whole.
The instant the bead reached his stomach, a warm, thick wave of pure vitality erupted within his core. It felt as though a torch had been ignited in the middle of a frozen wasteland. The pure blood energy rushed violently through his torso, soaking into his muscle fibers, his bone marrow, and his skin. The persistent, dull ache in his shattered meridians receded significantly, replaced by a powerful surge of raw, physical strength.
He stood up slowly, his joints popping like dry twigs breaking in a quiet forest. He raised his right hand, clenched it into a tight fist, and lightly struck the solid iron wall of the nearest cauldron.
THUD!
The massive, heavy iron cauldron shook on its stone pedestal, leaving a shallow but clearly visible dent where his bare knuckles had made impact.
Railin looked at the dent in the metal, then down at his unblemished knuckles. There was no pain, no skin tearing, and no bleeding. His physical strength had nearly doubled in a single night of work.
He turned his gaze back toward the rest of the dark chamber. There were still twenty cauldrons left to clean, and dozens of heavy wooden crates filled with unsearched furnace slag waiting in the shadows near the back walls.
The corners of Railin's lips twitched upward into a cold, predatory smile that never reached his eyes.
"Overseer Lin," Railin whispered softly into the quiet smoke, his voice carrying a dark, dangerous promise as he walked toward the next pile of discarded waste. "Keep sending me your trash. Please.
See you in next chapter....
