Chapter Text
The winter bells of the capital rang out three months later, their deep, metallic tones muffled by a thick blanket of fresh snow that had settled over the tiled roofs of the Jade Pavilion.
Maomao sat by the small charcoal brazier in her private room, a cup of bitter, hot chicory tea resting near her knee. Across from her sat Jinshi.
His hands were completely healed now, the white bandages replaced by his usual pristine skin, but his face still carried a lingering, quiet gravity that hadn't left him since the autumn inspection.
"The Ministry of Works has completed its internal purge," Jinshi said softly, his eyes fixed on the glowing orange coals of the brazier. "Six high-ranking ministers were stripped of their titles last week. Four provincial tax collectors were arrested at the northern border trying to smuggle three chests of unrefined silver out of the country."
"And the charcoal manifests?" Maomao asked, her voice entirely flat as she sipped her tea.
"They match the gate records now down to the single pound," Jinshi replied. He looked up, his beautiful, liquid eyes fixing on her with a mixture of intense curiosity and irritation. "You've been remarkably quiet about the whole affair, Maomao. Ever since the guards found you 'wandering' along the lower riverbank three months ago, you haven't asked a single question about Ruòyān or the northern mines. It isn't like you to abandon a mystery before the anatomy is clear."
"The mystery was resolved the moment the fire went out, Master Jinshi," Maomao said smoothly, setting her cup down with a soft clack. "The rest is merely politics, and politics gives me a rash."
Jinshi pouted, leaning forward until his face was only inches from hers, his long hair brushing against the tatami mat.
"You're hiding something from me. I can tell by the way your left eyebrow twitches whenever I mention the Ministry of Works. Gaoshun thinks you found something in that canyon, but my divers searched every inch of that cliff face and found nothing but wet moss."
"Then Master Gaoshun should spend less time speculating and more time checking the quality of the palace ginger supply," Maomao observed, her face flattening into her standard deadpan mask. "It has been entirely too woody lately."
Jinshi sighed, realizing for the hundredth time that trying to pry a secret out of Maomao when she didn't want to speak was like trying to extract venom from a dead viper. With a dramatic, heavy groan, he stretched out on her floor, his expensive purple silk robes pooling around him like a tragic puddle of luxury.
"You are a heartless creature," he mumbled into his sleeve. "I risk a diplomatic crisis to ensure your safety, and I am treated like an unwanted tax collector."
"Please do not drool on my floor mat, Master Jinshi. The moisture will attract the mold," Maomao said, already rising to her feet to fetch her medical mortar.
She waited until Jinshi finally left the pavilion later that evening, his dramatic retinue escorting him back to the central offices through the falling snow.
Once the courtyard was completely quiet and the outer bolts were secured by Yinghua, Maomao walked over to the hidden floorboard beneath her bed.
She lifted the wood and pulled out the wolf-
hide journal: For the Ones Who Didn't Get Their Revenge.
Sitting by the dying embers of the brazier, Maomao opened the final chapters of the text—the sections she had read over and over again until the words were burned into her memory.
This was the data that Ruòyān had paid for with her life. This was the detail that filled every single gap in the plot.
The journal didn't just track weights and measures. It was a precise, terrifyingly detailed chronicle of an economic execution.
According to Ruòyān’s records, the northern mountain mines hadn't been seized due to a standard administrative decree.
The plot had begun five years ago, when a unique vein of rare, highly concentrated blue-stone saltpeter was discovered deep within the private ridges owned by the Ruò clan. This specific variant of saltpeter possessed an oxygen density three times higher than common white powder—making it the essential ingredient for creating lightweight, high-velocity explosives that could breach city walls in a single blast.
The Ministry of Works, realizing the military and financial value of the vein, had tried to buy the land for a fraction of its worth.
When the Ruò stewards refused, a document was drafted within the inner court—a forged decree accusing the family of hoarding imperial resources and plotting an insurrection with the western desert tribes.
Maomao turned the page, her eyes locking onto the copy of the execution order Ruòyān had painstakingly transcribed from the stolen archive blueprints before she burned the building down.
At the bottom of the page was the signature of the man who had authorized the destruction of the Ruò clan. It wasn't a corrupt minister, nor was it a rogue general. It was the personal seal of the Grand Imperial Chancellor—the Emperor’s own uncle, a man whose political influence controlled half the standing army.
The charcoal smuggling operation hadn't been a petty crime for personal wealth. The Chancellor had been systematically skimming the high-grade saltpeter and northern coal out of the provincial shipments for years, hiding the excess density by adding weight to the palace charcoal bins.
He was building a private arsenal of Ruòyān’s family explosives inside the capital's central armory, preparing for a coup that would replace the current Emperor with his own lineage.
Ruòyān had entered the Rear Palace with a single, absolute objective: to use her family’s own chemical creations to destroy the foundation of the court before the Chancellor's coup could begin.
The poisoning of Lady Gyokuyou’s soup had been a calculated attempt to frame the Chancellor's primary faction within the western pavilion, drawing Jinshi’s internal security network directly into the administrative trail.
And the bomb at the promenade? It had been her final, desperate gamble to force the Emperor into a zone where the weakened foundation would collapse, erasing both the sovereign and the corrupt court that had signed her brothers' death warrants in a single, roaring avalanche of stone.
Maomao closed the journal, the heavy wolf hide cool against her palms.
Ruòyān had failed to destroy the throne, but she had succeeded in something far more lasting. By burning the Archive building, she had forced Jinshi to investigate the missing tax records.
By leaving the journal to Maomao, she had ensured that the true identity of the Chancellor’s smuggling ring would eventually reach the only administrator smart enough to dismantle it without causing a civil war.
Maomao stared into the grey ash of her brazier. She reached into her pocket, pulled out the small paper note Ruòyān had left her, and dropped it into the dying red spark of the coals.
The paper flared into a brilliant, tiny blue flame—the unmistakable color of burning northern saltpeter—before turning into a delicate curl of grey ash that drifted up into the dark room.
"I won't waste the knowledge, Ruòyān," Maomao whispered to the quiet night. "But the next time you design a delayed-friction fuse, use less sulfur. It makes the smoke entirely too difficult to wash out of an apron."
She slid the journal back beneath the floorboard, blew out her candle, and finally went to sleep, the rhythm of her own breathing perfectly matching the steady, cold fall of the winter snow outside.
After a while, she decided to rest until nightfall. It was very unlikely master jinshi would reprimand her.
The snow had stopped falling, leaving the inner courtyard of the Jade Pavilion trapped in a heavy, crystalline silence. The fire in Maomao’s small earthenware brazier had crumbled entirely to pale white ash, the last of the heat radiating feebly against her ankles.
She sat motionless on the woven tatami mat, the wolf-hide journal closed tightly in her lap. Her thumb traced the rough, uneven stitching of the spine.
Ruòyān’s words still echoed in the quiet corners of her mind.
It wasn't a minister, Maomao. It was the Grand Imperial Chancellor.
It was a terrifyingly clean piece of data. If Maomao handed the book to Jinshi tomorrow, the internal security of the empire would shift like a fault line. The resulting purge would not just strip a few corrupt officials of their silk robes; it would bleed the imperial family itself.
High-ranking consorts would be forced to drink poison in the night, infant heirs would quietly disappear from their cradles, and Jinshi’s beautiful, obsidian eyes would lose whatever warmth they had left, hardened into the cold, calculating glass of a ruler who had to destroy his own blood to keep the peace.
A perfect chemical reaction always leaves a residue, Maomao thought, her gaze fixing on the cold gray ash before her. If you attempt to neutralize a base with too much acid, the container itself explodes. Is it truly worth balancing the ledger if the scale itself breaks?
For the first time in her life, the truth felt less like a rare, intoxicating medicine and more like a volatile, delayed-action toxin.
She wasn't a politician; she was an apothecary. And a good apothecary knew when a substance was simply too concentrated for the patient to survive.
With a slow, deliberate movement, Maomao stood up. She slid the heavy journal back into its dark, hollow slot beneath the floorboard, carefully resetting the cedar plank until the grain aligned perfectly with the rest of the floor.
No one would find it. Not Jinshi, not Gaoshun’s hounds, not the Emperor’s guards.
She walked to the small wooden lattice window, pushing it open a fraction of an inch to let the freezing night air clear the lingering scent of smoke from her head.
The Rear Palace was vast, a labyrinth of white stone walls and dark tiled roofs sleeping beneath the pale light of the winter moon.
Down below, the river rushed through the deep canyon, its frozen edges glittering like shattered glass. Divers had searched that water for weeks.
They had found torn fabric, pieces of scorched wood, and the shattered brass casing of a crude grenade. They had declared the assassin dead by drowning.
Maomao’s eyes wandered down to her own windowsill.
The wood was lightly dusted with fresh, unblemished snow—except for a tiny, distinct spot right on the outer ledge.
Maomao leaned closer, her breath forming a small cloud of white vapor in the cold.
There, pressed lightly into the frozen wood, was a faint smudge of dark, greasy soot. It wasn't the charcoal ash from her own brazier, nor was it the soot from the palace chimney pots. It carried a tiny, microscopic trace of a very specific, bitter residue.
Bituminous stone dust. From the northern ridges.
Right next to the soot smudge, written into the frost of the window frame with the quick, sharp stroke of a fingernail, was a single, tiny character. It was the northern shorthand symbol for a standard chemical ratio.
Three parts saltpeter. One part sulfur.
Maomao froze, her fingers gripping the edge of the lattice. Her heart gave a sudden, sharp, and entirely unhinged flutter—not from fear, but from the raw, intoxicating realization that the experiment wasn't over.
The velocity of the fall had been calculated perfectly. The river hadn't been a grave; it had been an exit strategy.
A tiny, slow smile—the dangerous, brilliant smile of a mad scientist who had just discovered a hidden variable in her equation—crept onto Maomao’s lips.
She looked out across the dark, silent walls of the palace, her mind already spinning with the possibilities of the next formula.
She pulled the window shut, clicking the latch into place with a sharp, decisive snap.
"Three parts saltpeter," Maomao whispered to the empty room, her voice a soft, gravelly rasp of pure amusement. "You really are an insufferable liar, Ruòyān, and I'll bring my notes yet we meet again."
