The stench of rust and something acrid, like burnt ginger, filled the air. Gu Beiyuan lay still, a grotesque pool of obsidian ichor spreading beneath his face. His chest barely moved, a shallow tremor against the ornate rug. Chuyin knelt, her expression unreadable. She pressed two digits to his neck, finding a pulse thready as old silk. The meridian rot, she realized, was far more advanced than she’d thought. Her stabilizing needles had bought time, but not arrested the rot. The Firebird Cinders, a potent catalyst rumored to exist only in the archives of the Ministry of Inquest, were no longer an abstract luxury. They were his only chance of drawing breath by dawn. She rose, her eyes sweeping over the splattered desk, the scattered papers, then to the closed doors. Her lips thinned. “Very well, Gu Beiyuan,” she murmured, a promise sharp as shattered glass. “Let’s see if you’re worth this trouble.” Minutes later, Chuyin stood before a grumbling Duanmu Fei in his cramped, fume-choked lab. The air shimmered with the heat of his distillation furnaces, and jars of iridescent compounds lined every shelf. Duanmu Fei, clad in stained leather gauntlets, was meticulously crushing dried scorpion husks with a pestle, a look of focused annoyance on his face. “Pardon the intrusion, Duanmu,” Chuyin said, voice flat. “But Commander Gu requires a rather… unique ingredient.” Duanmu Fei grunted, not looking up. “The Commander needs rest, not more of your concoctions. Your last ‘tonic’ had me chasing phantom centipedes for two days.” He flicked a speck of scorpionic dust from his brow. “And don’t think I haven’t noticed your digging around the Scarlet Dewbells in the southern plots. That plant withers without precise distillation. Your clumsy paws will ruin the batch.” Chuyin allowed a faint, patronizing smile to play on her lips. “My touch is rough only with garden weeds. What I need now requires an expedition to the capital.” Duanmu Fei finally looked up, his brow furrowed. “The capital? You have lost your senses. The Inquest archives are barred like an iron tomb, and stepping within twenty paces invites a headsman.” He eyed her suspiciously. “What exactly do you need?” “Firebird Cinders,” Chuyin stated. “From the fourth sub-level beneath High Minister Zaiyun’s private keep.” Duanmu Fei’s jaw went slack. He dropped the pestle with a clatter. “Those cinders are fable! Even if real, the Night Guard patrols the halls, smelling for herbal tinctures from three corridors away. Zaiyun inspects the seals weekly.” He swallowed hard. “You might as well ask me to steal the Emperor’s crown.” “Then you can show off your skill,” Chuyin said. “If Gu Beiyuan dies, the estate falls to scavengers. Your gardens, your Scarlet Dewbells, and your dried scorpions will be burned. You will inherit only ash.” Duanmu Fei sputtered, blood rushing into his cheeks. The threat was concrete, undeniable. He adored his lab, his work. He would not lose it. “Fine,” he snapped. “One blunder, and I leave you to the Inquest interrogators.” The journey to the capital was swift and silent, undertaken under the cloak of deepest night. Duanmu Fei navigated hidden drainage ducts and sentry shifts without pause, bitterness toward the high officials outstripping his caution. They dropped into the stone foundations beneath the Ministry compound, where stagnant cellar air smelled of wet slate and copper salts. The reinforced iron gate matched his warnings: etched counter-seals inlaid in bronze, guarding against intrusion. Duanmu Fei meticulously deactivated a pressure plate that would have released a cloud of neurotoxin, then disabled a sound-triggered array of spring-loaded darts. Chuyin, however, moved with a different kind of grace. She traced patterns on the cold stone walls, her fingertips finding invisible fissures, her presence barely disturbing the dust motes in the air. She produced a small vial of luminous green liquid, applying a single drop to a minute pinhole near the vault's locking mechanism. A soft hiss, then a faint click echoed in the silence. Duanmu Fei watched, transfixed. “That solvent ate straight through meteoric iron,” he whispered, staring. “I have only read of such a compound in the forbidden records of Ren Muxue.” His eyes, usually clouded with arrogance, snapped to Chuyin. “The green smoke, the scent of parched pine... it matches her treatise precisely. But she was executed.” Chuyin offered him a cool, unbothered glance. “Necessity demands results, Duanmu. Or an old recipe remembered.” Duanmu Fei’s jaw worked, his gaze now filled with a fervent, almost worshipful intensity. “You survived,” he rasped, stepping closer. “The Frost-Bite Lotus... the serpent distillations at the estate... it was you all along.” He leaned forward, voice dropping to an eager hiss. “I spent years dissecting your formulas. Tell me what needs breaking next.” Chuyin suppressed a sigh. This would be even more tedious than she anticipated. “Quiet down,” she replied, shoving the heavy panel open. “The jar sits in the central coffer. Mind the floor plates.” The interior reeked of camphor and lime, damp stone biting through their boots. Shelves bore rows of labeled urns and dried root bundles. Chuyin moved with purpose, heading towards the central plinth. Duanmu Fei, meanwhile, was darting between stacks of classified documents, his earlier awe giving way to an almost manic excitement at being in the legendary vault. “Look—the missing field notes from the Blood Plague, and whole roots of preserved Winter Mandrake!” Chuyin ignored him, her focus absolute. She reached the plinth, a heavy crystalline box resting upon it. Inside the lead-stoppered vial lay the cinders, glowing like faint orange embers. She reached for it, her goal agonizingly close. But as her hand closed around the crystal, a hidden compartment slid open beneath her touch. Inside, nestled amidst a stack of sealed documents, was a scroll bound with black silk. Its label was stark: “Case File: Ren Muxue. Treasonous Alchemist. Autopsy Report.” Her fingers hesitated against the ribbon. She pulled it out, unrolling it with a practiced flick of her wrist. The script was precise, the details gruesome. Her own mortuary ledger. Her sight skipped past the forged cause of death—heart stoppage via bitter hemlock—and stopped on the red imperial wax seal bearing Emperor Jinyue’s personal signet. The Emperor himself had written the order, bypasssing ministerial trials entirely. The imperial seal meant her enemies had never been mere court rivals. Her freedom wasn’t just a matter of dismantling a faction; it was about surviving the wrath of a monarch. “Bolts drawn behind us!” Duanmu Fei hissed, leaping away from a display table. Heavy footsteps echoed from the vault entrance. A deep, resonant voice boomed, “Only one dead heretic distilled an acid that leaves green frost on tempered iron. You crawl back from your grave, Ren Muxue!” Chuyin spun around. High Minister Zaiyun blocked the archway in gold-threaded robes, supported by a dozen crossbowmen. He dropped his hand toward the release winch. “Drop the ceiling bars! Flood the lower floor with viper vitriol!” The iron slab slammed down into its floor groove with an ear-splitting crack. A soft hiss began, emanating from hidden vents in the ceiling. Yellow vapor sprayed from overhead brass grates, stinging their eyes.
