The morning swept through the eastern bamboo grove, casting pale shafts of light into the bamboo cabin.
The interior of the room reeked of a violent transition of flesh. The rustic smell of black sludge and rust, residue of the mortal filth expelled in previous weeks, still impregnated the earth beneath the floor. That rotting odor, however, was aggressively crushed by the thick, sweet, and lethargic perfume that soaked the straw of the bed and the linen sheets after twenty-four hours of uninterrupted friction.
Seated in the center of the ruined mattress, her cotton nightdress slipping off one pale shoulder, Yù Qíng sat with her eyes closed.
The young woman's chest rose in a long breath. The intention of guiding the energy resting in her own abdomen marked the tense line of her jaw. The air escaped her lips in a hissing whistle. The invisible matter inside her veins stagnated halfway, dissipating in useless heat against her own ribs.
Zhì Yuǎn stopped at the threshold of the door, blocking the light from the veranda.
The man held three rolls of aged parchment and two books bound in raw leather beneath his right arm. He had just crossed the grove, coming from the main house. Upon seeing his wife trying to guide the energy, his dark eyes dissected the layers of muscle and silver beneath her pale skin. He saw the lethargic flow and the exact point where the pressure spread in vain before reaching her arms.
He walked silently into the room.
Zhì Yuǎn threw the books and scrolls onto the small bamboo table with a hollow snap and sat on the edge of the mattress, the straw creaking beneath his weight. His warm, calloused hand rose. The index and middle fingers pressed the base of Yù Qíng's left clavicle, sinking exactly over the small gap in the bone.
"The curve of this channel up here is too narrow for the volume you are trying to push all at once," his grave voice vibrated in the silent room, pointing out the structural flaw. "The flow hits the bottleneck and splashes to the sides. Divide the force. Pull the first half to the left arm, and the rest follows the vacuum."
Yù Qíng blinked, absorbing the command. She drew breath again, adjusting the pressure against the bone he indicated.
A shiver ran up the girl's spine. The energy unlocked in the narrowing and slid freely through her pale arms, circulating without any friction.
She opened her black eyes. Yù Qíng slid across the mattress, the open nightdress revealing the skin marked from the previous night, and pressed both knees against his leg. Her icy hands rose and gripped the fabric of the charcoal-gray tunic on Zhì Yuǎn's chest, squeezing the linen with force.
"You see the knots I do not see, A-Yuǎn," she whispered, face centimeters from his, breath beating hot against her husband's chin. "You never miss the cut."
His immense hand rose, and his warm fingers descended directly to the center of the girl's chest. The calloused thumb rested with millimetric precision upon the smooth skin below her sternum.
The exact place where, weeks earlier, he had injected a hyper-pure fire and nearly incinerated the wife's veins from within, crushing her in convulsions of blood.
Zhì Yuǎn's dark gaze bored into that pale skin, feeling her human pulse beat beneath his own thumb.
"I almost killed you on the straw of this bed, Qíng," his reply descended grave and irreducible, driving the bloody memory into the room. "Luck is not something I can trust when it comes to your life. You are my absolute foundation. Playing at forcing energy through bones without knowing what we are swallowing is the fastest path for me to shatter you from within for good."
Yù Qíng fell silent. The heat from the tips of her husband's fingers against her sternum radiated the physical warning of that deep burn.
Zhì Yuǎn withdrew his hand and rose from the bed. He walked to the bamboo table and pulled the leather cord of the first scroll he had brought, opening the paper over the rustic wood.
"The peddler passed by the main house yesterday," he said, voice returning to the monotonic tone. "I used the silver left from the mine to order this from the capital's merchants weeks ago. I went to fetch it this morning from your father's veranda. There are ancient records here."
Yù Qíng rose from the bed and walked to the table, stopping pressed against his left arm.
Zhì Yuǎn's calloused finger tapped dryly over a character in the text.
"The matter we swallowed and that purified our flesh. The books call it Qi," he slid the finger to a rudimentary diagram of a human body, dotted with thick lines. "And the hollow fissures through which it runs beneath our muscles are the meridians."
Yù Qíng's breath caught lightly. The terms gave solid, real contours to what they had been grinding alone in the darkness.
"And there is more," he continued, opening one of the leather books. "There is information that much farther south, beyond the mountains, there exist settlements of people who use this Qi to strengthen the body in the same way we do. They call them Cultivators. Men who gather in communities called Sects. The texts say that, with advancement, they can manipulate the weight of objects at a distance merely with the mind."
He set the paper on the bamboo and turned his face to his wife.
"We are walking in the dark, Qíng, groping at what we do not know," Zhì Yuǎn sentenced, distilling raw reality. "If I make another miscalculation, it could be fatal for you or for me. We have already seen that Qi alters our cells from the inside out. Sooner or later, the limits of Qīngshān will suffocate what we are becoming. We will need to cross the road and explore those larger cities for answers, before ignorance destroys the very body we have just refined."
The realization weighed upon the small bamboo table, silencing the noises of the wind outside.
Yù Qíng looked at the old scrolls spread across the wood. Knowing that anomalies existed in the extreme south of the continent did not frighten her; what made the girl's short nails tighten on her own nightdress was her husband's naked, raw warning that lack of knowledge would shatter them from within.
Zhì Yuǎn sustained the gaze. He rolled the scroll slowly, the young man's mind already organizing the pieces of that revelation.
"During the last twenty-four hours in which we locked the door, I did not maintain the friction only to widen our veins, Qíng," the man's grave voice broke the quiet, cadence returning to the methodical tone. "The pain in my head nearly cracked my skull because I pushed the gears of our mill beyond the biological limit we already knew."
He raised his hand, calloused thumb pointing to his own chest.
"I took the purest matter from the seventh breakage and threw it back into the iron teeth. I forced the eighth rotation. And when it shattered, I did not stop. I crushed what remained until the axle locked and forced the ninth inversion."
Yù Qíng's breath locked. The memory of the excruciating exhaustion from the previous day made her spine retract in a mute spasm.
"The friction shattered the foundation of the matter on the ninth strike," he continued. The man's unfathomable gaze descended to the young woman's face. "No trace of ice or fire remained. The aggression of temperature evaporated. What poured from the mill was an incredibly thin, sparse moisture, difficult to hold, but that gleamed beneath my vision with a purely golden density. It is the nucleus of what keeps flesh united. I call it Primordial Qi."
Yù Qíng blinked, lips parted. Her pale hands rose, gripping the sides of his dark tunic, hungry for the weight of that distilled gold.
But the memory of the long, exhausting dawn brought another uncomfortable memory to the surface. The pout of contrariety bloomed on the wife's face.
"We would have turned that gear with much greater ease if Méi had stopped banging on the door and screaming in the middle of our cultivation," she complained, velvety tone dripping silent fury against the interruptions. "The plague does not understand that the locked wood means we want no one nearby."
The movement of Zhì Yuǎn's hands over the books stopped immediately.
His dark eyes widened slightly in the penumbra, a rare trace of genuine surprise cracking the cold wall of his expression.
"While she was kicking the door from outside and you were demanding that she leave, I looked at her through the bamboo slats, Qíng," he murmured. "I expected to see thin, dry, or withered channels. But what I saw beneath her skin left me stunned."
Yù Qíng furrowed her brows, attention nailing itself to the break in her husband's posture.
"Méi's meridians are shattered," he sentenced, the initial shock giving way to a metric coldness. "Entire pieces are missing between the girl's chest and arms. The space beneath her sternum is a perforated basin. The Qi of the world has nowhere to hold there. Even if she sucks the air a thousand times, the energy will leak through the holes before nourishing the flesh. Her foundation rotted before it could even take root."
Silence reigned for a full second. The rigid tension in Yù Qíng's jaw dissolved. Hiding her husband from the rest of the village was an unbreakable law, but realizing that the youngest's foundation was a dead, inoffensive abyss chilled the young woman's blood, making her blink slowly.
Zhì Yuǎn raised his thumb and brushed his wife's tense jaw.
"The energy the world spits at dawn is not pure enough to solder broken pieces. And the ice and fire we use would explode her organs from the inside out," he explained, dry and direct. "But the golden thread of Primordial Qi we tore from the ninth rotation does not expand and does not cool. It rebuilds the origin. If I can pour enough of that sparse matter into the base of your sister, the energy will solder the splinters and plug the holes."
The temperature of the cabin plummeted.
Yù Qíng's short nails sank into the thick fabric of Zhì Yuǎn's tunic, twisting the linen against his chest with a force that made the girl's knuckles crack.
"The mechanism we created requires that bodies mix," her velvety voice descended to a strangled hiss, the musculature of her slight body trembling beneath the blind fury of one who sees her own borders threatened. "You only transfer what you grind by injecting your matter through the hips or by blowing through my lips. If you touch her the same way you touch me to pass on the gold we both forge, I do not care if she shares my blood, A-Yuǎn. I will break her neck."
The homicidal warning did not make Zhì Yuǎn retreat a single millimeter.
He knew the woman he held in his hands. He did not try to argue morality or calm his wife's fury. The young man's immense hand merely slid to Yù Qíng's pale nape, large fingers threading through her black hair, locking the girl's face against his own chest.
"My flesh does not enter any place that is not you, Qíng," he declared, voice crushing any doubt, heavy and non-negotiable.
The tension in the wife's shoulders collapsed instantly. She gasped, cheek sinking into the curve of his tunic, eyes closed absorbing the carnal vow.
With Yù Qíng pressed against his own body, Zhì Yuǎn used his free hand to tap his knuckles on the leather book on the bamboo table.
"And we will not need the sweat of the mouth or friction to heal her," he continued, practical and focused. "The texts prove that gears can be pushed. If the southern cultivators can manipulate the weight of objects at a distance merely by forcing will outward, it means Qi does not need skin collision to be injected."
Zhì Yuǎn crossed the penumbra with his gaze, the pieces of the new mechanism fitting silently in his mind.
"I only need to learn to force the Golden Qi directly out of my own pores and guide it through the air to Méi's chest. The problem is that throwing it into empty space will drain us dry. If I miss the aim or the force, the matter will evaporate in the wind and the effort will be useless. We will need to grind thousands of times more than we already do until I can expel enough without fainting."
Yù Qíng turned her face against his tunic. Her crimson lip drew a smile in the shadow of the embrace, rage extinguished by the absolute certainty that she would be the inexhaustible source of that friction.
"Then empty whatever you want from me," she whispered, the tips of her fingers scratching his massive musculature. "We forge the gold on the bed until the roof of this cabin yields."
The whispered promise vibrated against Zhì Yuǎn's ribs, but the young man's dark gaze descended to his own right arm. With his skull still throbbing from the previous day's effort, he focused on his own skin. The surface of his forearm was smooth and untouched, displaying the rigid pallor of freshly refined flesh.
"The black mud stopped dirtying the stream water at the end of the third week," his grave voice broke the quiet, dragged and evaluative.
Yù Qíng raised her face slowly. She looked at the arm he stared at.
"The body expelled what rotted the bones," the wife replied, pale fingertips tracing his rigid musculature.
"That is what I deduced first," he retorted, jaw locking slightly. "But old wood always keeps dust at the bottom of the veins, Qíng. The filth did not stop coming out because we are completely clean. It stopped coming out because the house is locked from the inside."
The young man's inner vision crossed the skin and the thick meridians pulsing beneath the rigid muscles, focusing directly on the extreme border of the body. Millions of minuscule holes covered the extent of his anatomy. They were natural fissures sealed, clogged by a hard crust of mud that the pressure of the flesh in previous weeks had not had force to eject.
He chose a single point on the back of his own right hand.
Zhì Yuǎn pulled a fraction of the thick Qi running in the great river of his arm. The pressure in his temples drove the veins against his skin. He forced that thread of energy to abandon the safety of the main meridian, pushing it through smaller secondary channels that had been dry and dead since the day he was born. The Qi advanced, tearing the internal tissue millimeter by millimeter, until it collided against the base of the clogged pore on the surface.
The energy accumulated there, blocked by the hardened crust.
Zhì Yuǎn pushed the Qi from below upward against the blockage in a blow of pure will.
Crack.
The snap sounded clear in the cabin's quiet.
A minuscule, blackened grain jumped from the back of Zhì Yuǎn's hand, thrown into the air and falling onto the bamboo table with a hollow click. The pore gaped open.
Yù Qíng held her breath. That microscopic hole did not bleed. With the pore open and the secondary channel hollow, the internal vacuum pulled the only thing that existed on the outside.
A thin, icy thread of the nocturnal air cutting through the bamboo grove outside was sucked directly into Zhì Yuǎn's body. The world itself infiltrated without the slightest resistance through that millimeter torn of skin.
Zhì Yuǎn opened his eyes, chest rising in a long breath.
"Breathing does not need to use the throat or the lungs," the voice reverberated, thickened by the weight of what he had just discovered. He turned his hand, feeling the continuous thread of ambient energy feeding his own flesh without his diaphragm moving. "There are millions of locked doors in our husk. If I breach each one of them and spit out the last dust, the energy around will enter and nourish the veins all the time. Dry exhaustion."
Yù Qíng's black irises dilated as she followed the lethal logic. Her pale hands gripped her husband's wrist.
"And with these doors thrown open," the wife whispered, words hurried, "you will not need physical touch. You will be able to vomit the Primordial Gold outward."
"Yes," Zhì Yuǎn agreed, eyes nailed to the minuscule grain of dark mud on the table. "But tearing the locks from millions of microscopic fissures will not be quick. It will consume every drop of friction we generate on the straw of this bed."
The darkness in the woman's eyes thickened before the insurmountable foundation those open doors would bring to both their bodies.
She spread her icy hand against his scalding chest, feeling the channels throbbing beneath the rigid muscles.
"Then we will not waste a single second," she sentenced.
---
The midday sun began its descent, tinging the bamboo grove's shadows with an ochre, thick tone.
The wet, predatory cadence of friction on the straw bed finally ceased. Zhì Yuǎn rose from the ruined mattress, his broad body gleaming in the cabin's penumbra. He walked to the heavy cedar chest in the corner of the room, removing a clean charcoal-gray tunic and thick cotton pants.
He did not need water to wash his skin; the Qi now circulating freely through his newly opened pores repelled sweat and dirt before they even dried.
"The imperial intendant's inspector arrives tomorrow at the first light of dawn," Zhì Yuǎn's grave voice broke the environment's static. He dressed in the tunic, tying the leather belt at his waist. "Your father will need to weigh the hundreds of coal sacks this afternoon in the courtyard. His old iron scale has rust on the axle and sticks the weight. If the bindings are loose, the imperial bureaucrat will use the moisture as an excuse to take double the village's quota."
Lying on the sheets, Yù Qíng opened her eyes. The cold air of late afternoon entered through the gaps and struck the girl's pale face.
She looked at her own bare, marked legs, and then followed her husband, who was finishing adjusting the sleeves of his clothes. The world of Qīngshān and the tax rules demanded attention. Zhì Yuǎn's icy eyes were the only thing capable of preventing the Yù family from being crushed by theft and their disguises from falling. But the idea of walking to the main house and enduring the voices of the cart drivers made her jaw lock.
"The noise of those people gives me a headache," the wife murmured, velvety tone dripping aversion. Her icy hands rested on the mattress. "I will not cross the forest today."
Zhì Yuǎn put on his leather boots and walked back to the edge of the bed. He accepted the refusal in silence. His large hand descended, gripping Yù Qíng's nape with firmness, thumb brushing the bone of the young woman's tense jaw.
"The courtyard will smell of horse sweat and soot until night. Stay and rest, Qíng," he sentenced, vibrating the order against her face.
He released his wife's nape, walked to the cabin door, removed the wooden bar, and descended the steps, marching toward the main house to seal the mortal bonds that kept them untouchable.
Yù Qíng observed from the bed the exact point where his gray tunic vanished into the bamboo foliage. The girl's slow breath filled the silence and she raised her body, bare feet finally stepping on the floor.
The smell in the room was asphyxiating. The focused concentration on blind friction had exacted a filthy price from the environment. The bamboo floor displayed dark, dry stains — the black, toxic mud, vomited from their pores during the transition, had hardened against the wood like pitch crusts. Above that, the straw bed and torn sheets were ruined, stiff with the sweet, inebriating mixture of nectar and sweat from both after continuous cycles of carnal collision.
To any mortal, the cabin would seem like a fetid slaughterhouse erected inside an abandoned brothel.
Yù Qíng's pale nose wrinkled at the offense of seeing the poisoned earth dirtying the temple where Zhì Yuǎn's purified skin would need to rest.
The girl grabbed a large rustic wooden bucket, descended to the icy stream, and filled the tub to the brim, carrying the weight that weeks earlier would have made her wrists crack with pain. She lit the clay forge in the kitchen, throwing boiling water, a block of ash soap, and a thick cloth on the floor.
The young woman fell to her knees on the bamboo slats, plunging her hands directly into the bubbling water. The hardened flesh did not form blisters; the temperature merely tinged her palms red. She squeezed the scalding cloth and scrubbed it violently against the stained floor.
The friction of her hands against the wood was brutal. Yù Qíng scrubbed the planks in aggressive, uninterrupted thrusts, teeth locked as the ash soap melted the toxic mud, transforming the water at the bottom of the bucket into a dark, foaming slime. The smell of rot rose strongly through the steam, but she scraped the dead filth with her short nails, tearing every remnant of human failure that had leaked from their bones, until the original bamboo appeared polished.
When the sun disappeared completely and the shadows of night swallowed the cabin, the entire room reeked only of damp wood and clean threads. Yù Qíng threw the old sheets soaked in fluids outside, replacing the straw of the bed with new.
In perfect darkness, the young woman sat on the edge of the mattress, bare feet resting on the unstained floor. Her chest rose and fell calmly, eyes nailed to the closed door, awaiting the exact instant when her husband's heavy step and scalding lethargy would return to take possession of the perfect space she had purified.
