The sound was wrong.
It was the first thing Lin Feng noticed upon waking on the ninth day. The deep, resonant hum of the main Alchemy Hall's primary formations was absent. In its place was a profound, ringing silence, broken only by the frantic scuffle of footsteps in the stone corridors outside his tiny room.
He pushed himself up, his body still a symphony of aches, though the bone-deep fatigue had lessened a fraction thanks to the strengthening broth. The system interface, a constant companion, pulsed with a neutral blue light. No new quests. [Interest Level: 18%] remained steady.
Before he could ponder the silence, the door to his storeroom slid open. It was not the servant automaton, but a junior alchemy disciple—a girl with her hair in tight braids and a face pale with anxiety. She was maybe sixteen, her eyes wide as they darted around the cluttered space before landing on him.
"You! The cripple from the ravine!" she hissed, her voice a strained whisper. "Elder Zhu demands your presence in the main refining chamber. Immediately!"
Lin Feng's heart, which had begun to settle into a cautious rhythm, lurched. Demanded your presence. Not 'requests.' Immediately. This was not a summons for a progress report. Something had happened. The baffle.
He nodded, grabbing his rough-hewn cane (a recent addition courtesy of the silent automaton) and levered himself to his feet. The disciple didn't offer help, already turning to hurry back the way she came. Lin Feng followed as swiftly as he could, his cane tapping a frantic, uneven rhythm on the polished stone floor.
The Alchemy Hall was a different beast today. The usual aura of serene, focused energy was gone, replaced by a thick tension. Disciples huddled in small groups, casting fearful glances towards the sealed double doors of the main chamber. The air smelled of ozone and… something charred.
The junior disciple stopped before the great doors, carved with images of phoenixes and cauldrons. She gave him one last, almost pitying look, then knocked once and fled. The doors swung open silently on their own, revealing the inner sanctum.
The main refining chamber was vast, dominated by three massive, ornate furnaces set into the floor. The central one, Number Three, the subject of his work, was cold and dark. Standing before it, her back ramrod straight, was Elder Zhu Yan. Her aura was not the controlled, chilly pressure from before, but a contained, seething storm. It pressed against Lin Feng's skin like the air before a lightning strike.
On the floor between her and the furnace lay the object of her fury. It was the cold iron baffle. Or rather, it was a twisted, partially melted lump of slag that had once been the baffle. Wisps of acrid smoke still curled from its surface.
"You," Elder Zhu said, her voice so quiet it was more terrifying than a shout. She did not turn around. "Explain."
Lin Feng's mind raced. The baffle had failed. Catastrophically. Had his design been flawed? His material analysis wrong? He activated his Passive Scan on the ruined metal, pushing through his own fear.
[Material: Reflective Cold Iron (Slagged/Degraded).]
[Spiritual Grade: N/A (Qi-contaminated).]
[Analysis: Subjected to extreme, localized Yang-fire energy surge exceeding its structural and spiritual tolerance. Failure due to external overload, not design flaw.]
Relief, cold and sharp, cut through his panic. The baffle didn't fail. It was overloaded.
"Elder," he began, his voice steadier than he felt. "The baffle did not fail in its intended function. It was destroyed by an external force. The furnace flame… it spiked. Severely and suddenly." He pointed a shaking finger at the slag. "The melting pattern is concentrated on the leading edge. It was a focused blast from inside the vent, not a general failure of the piece."
Elder Zhu finally turned. Her face was a mask of jade, but her eyes were volcanic. "I am aware of the spike, disciple," she said, each word dripping with frost. "The 'Shearing Baffle,' as you called it, worked. For precisely forty-seven minutes. The heat distribution in the crucible was fifteen percent more uniform than any previous run. The Moonlight Grass fused perfectly."
Lin Feng blinked. It… worked? Then why the fury?
"And then," she continued, taking a single, measured step towards him, "the 'Crimson Salamander's Heart,' the catalyst added in the final stage, reacted not with the stabilized ingredients, but with the baffle's diffused energy signature. It caused a resonant feedback loop in the furnace's core script. The result was a Yang-fire backlash that vaporized a batch of ingredients worth five hundred spirit stones and" —she gestured to the slag— "destroyed your device."
The blame wasn't on the baffle's design, but on an unforeseen interaction. This was beyond pattern recognition. This was high-level alchemical theory.
The system flickered in his vision.
[Crisis Quest Triggered: 'The Alchemist's Ire'.]
[Objective: Defuse the situation. Propose a viable solution to prevent future feedback. Failure will result in expulsion from the Alchemy Hall and termination of Stage 2.]
[Hint: The problem is not the tool, but the recipe. The system was stable before the introduction of the new variable (the baffle). The recipe must be adjusted to account for the new energy profile.]
Lin Feng swallowed. He had to think. Fast. This wasn't about fixing the furnace; it was about fixing the process. His modern mind latched onto the analogy. You don't blame a new gasket when an engine seizes; you check if the fuel mixture is right for the new compression.
"The baffle changed a variable," Lin Feng said, thinking aloud, his eyes fixed not on her but on the darkened furnace. "It changed the energy flow pattern inside the chamber. The original 'Morning Sun' recipe was calibrated for the old, asymmetrical flow. The new, uniform flow is a different environment. The catalyst… the Crimson Salamander's Heart… it's too aggressive for the new stable state. It's like… like adding a strong acid to a perfectly balanced solution. It doesn't react with the ingredients; it reacts with the balance itself."
He dared to look at her. "The baffle didn't cause the failure, Elder. It revealed a flaw in the recipe's underlying assumption. The recipe was designed to compensate for the furnace's flaw. With the flaw corrected, the recipe itself must be corrected."
The silence that followed was absolute. The searing pressure in the room didn't lessen, but it shifted, coalescing from blind anger into intense, razor-sharp focus.
"You suggest," Elder Zhu said, her voice now dangerously calm, "that my late husband's life's work, which I have spent decades trying to perfect, was built upon a foundational error?"
Lin Feng met her gaze. This was the precipice. One wrong word, and he was finished. "Not an error in his genius, Elder," he said, choosing each word with the care of a bomb defuser. "An error in the tool he was forced to use. He designed a masterpiece for an imperfect instrument. You have now perfected the instrument." He gestured to the cold furnace. "The masterpiece must be… retuned. To honor his intent, not his limitation."
For a long, agonizing moment, she said nothing. Her eyes bore into him, reading not just his words, but the tremor in his hands, the sweat on his brow, the desperate sincerity in his face.
Finally, she turned away, walking to a long table covered in scrolls and jade slips—the decades of research on the Morning Sun formula. "Retuned," she repeated, the word hanging in the air. She picked up a jade slip, her husband's notes, holding it with a reverence that was heartbreaking.
"A junior disciple with a broken dantian," she murmured, more to herself than to him, "who sees the world through its cracks, dares to tell me I have been polishing a broken mirror, not unveiling a masterpiece." She looked back at him. The volcanic anger was gone, replaced by a profound, weary exhaustion and a spark of… something else. Reluctant, furious curiosity.

"You will eat," she commanded, not looking at him. "Then you will return here. You will review every note on the Crimson Salamander's Heart catalytic stage. You will not offer solutions. You will list every interaction, every variable, every recorded stress point. In exhaustive detail. I will… reconsider the thermal equilibrium assumptions."
It was a monumental task. It was also a lifeline. And an admission, however small, that he might see something she had missed.
"Yes, Elder," Lin Feng breathed, the tension draining from him so fast he nearly stumbled.
As he turned to leave, leaning heavily on his cane, her voice stopped him at the door.
"Lin Feng."
He froze. It was the first time she had used his name.
"The Soothing-Bone Grass in your congee," she said, her voice once more the cool, detached tone of an Elder. "I have doubled the dosage. Do not waste it by fainting from exhaustion. Your… observations… are required."
He bowed deeply, a real bow this time, and hobbled out. The doors sealed behind him, shutting him off from the chamber of simmering frustration and dawning, painful revelation.
Back in his storeroom, the congee sat steaming. He ate mechanically, his mind churning. He had survived. More than survived—he had advanced. He had moved from being a cataloguer of failures to someone whose theories, however bluntly stated, were being given credence.
He looked at the system notification. 21% Interest. It wasn't affection. It wasn't even trust. It was the grudging, furious respect of a master mathematician for a savant who sees numbers in the clouds.
It was progress. It was the hardest-fought percentage point yet.
And somewhere, in the depths of his being, a tiny, unbroken part of him thrilled at the challenge. The first mountain was proving to be the most complex puzzle he had ever faced. And he was starting to see its shape.
