Having checked the theoretical premise in Article One, Seyun decided as a cold and exact observer to perform a strictly limited ten-breath flow along the tablet’s introductory guide-line before reading further. Mina had always insisted that an apothecary who wrote down a prescription without tasting a single drop of the decoction on his own tongue had no business dosing a patient.
Resting the palm-width blue-gray slate flat against his breastbone, Seyun lined up his thumbs along the upper-left groove corresponding to the first return arch beneath his left collarbone. He kept his eyes open on the northern spring-seep gutter. He used the four-second drip of the water to govern his rhythm so he could halt the test on the exact tenth breath out.
On the first three breaths, his frugal Coal warmth rose from his lower belly and entered the sound guide-line of the stone without pushback. On the fourth, fifth, and sixth breaths, the engraved slate conducted the pulse back into the crescent-shaped node behind his left collar bone, coaxing the inward check-valve to part by the breadth of a horsehair.
For three seconds—breaths seven, eight, and nine—Seyun felt what it was like to have the upper arch of his chest open. The choking band that had squeezed his lungs during every check since his fourteenth year vanished. His ribs felt wide, floating, and ringing as a dry cedar bell-frame.
Then, on the tenth breath, because there was no bound external counter-pressure waiting on the other side of the open valve to meet his rising Coal, the unanchored return current snapped back against the dry inner lining of his left chest muscle vessel.
Seyun halted his breathing pattern on the exact four-second drip and lowered the stone tablet to his knee. His jaw set was tight against a sudden, needle-sharp prickling heat that spread behind his left chest muscle.
He didn’t cough or clutch his chest—four thousand mornings of holding a level stance under strain kept his shoulders square—but when he placed two fingers of his right hand against the hollow beneath his left collarbone, he felt the tiny, rapid fibrillations of a dry spirit vein sheath that had been opened to the air without fluid to fill it.
Seyun looked down at the second leaf of Master Uren’s oiled mulberry letter. He found the dead teacher’s cold and exact note waiting for him in the very next paragraph, as if Uren had watched ages of students perform that exact ten-breath test and reach for their left collarbones afterward.
“You have now felt the dry prickle behind the left chest muscle,” Uren’s square handwriting read. “An open return arch that receives no external proof is like a mill-water gate raised in a drought: the dry timber of the gate warps in the sun. Nearly half of the early initiates of our house tore their own chest linings in their first month because they were too proud to wait, forcing solitary breath through the tablet’s guide-lines in the hope of mimicking a rival’s echo by sheer willpower.”
Seyun read the rest of the paragraph while keeping his breathing shallow and even. According to Uren’s medical ledger, clearing the dry inflammation caused by even a brief unbound opening needed two full hours of slow, low-pressure foundation breath flow. With a soothing mucilage mixed from calcined winter-reed pith and cold spring water.
Seyun reached into the fold between the second and third leaves of the mulberry letter. He lifted out the small twist of apothecary tissue he had noticed earlier. Inside lay two ounces of fine, stone-white ash burnt from the pith of mountain winter-reeds two hundred years ago, sealed so tightly in bitter pine-resin-waxed paper that not a grain of damp had reached it.
Seyun used the clean tip of his bronze belt-buckle tongue as a measure. He scooped three grains of the white reed-ash into the hollow of his left palm, caught four drops of cold stone water from the northern seep-stalactite. Then he rubbed the mixture with his index finger until it formed a cool, slightly viscid grey paste.
He touched a speck of the mucilage to his tongue. Then, he recognized the clean, alcaline bitterness right away. It was the exact same marsh-reed pith that Mina boiled with crushed pear-seed to coat raw throat membranes during Oran’s dry autumn winds, except calcined at a higher kiln heat so its stone salts absorbed instantly through the sublingual vessels under the tongue.
Swallowing the measured dose of reed-ash mucilage, Seyun set the stone tablet safely aside on the calfskin satchel, folded his hands in his lap. Then he began the slow, unrushed two-hour foundation breath flow prescribed by the letter. Letting his eyes continue to read the chiseled slate on his knee. Meanwhile, his lower belly quietly cooled the dry prickle behind his left chest muscle.
As the reed-ash salts entered his bloodstream and the slow fifty-six-beat rhythm of the first base form bathed the irritated vessel wall, the sharp needle-pricks beneath his collarbone gradually softened into a warm, manageable ache.
The lesson was written directly into his own muscle fibers, where no recorder could ever forget it. The Answering Spirit vein was not a toy to be forced in secret, and any try to rush its gates without paying for proper preparation and medicine would cripple him faster than an Aperture Court blade.
More than that, the fifty percent injury rate among the Counterpoise Sect’s early initiates explained why the method had never spread across the valley like wildfire even before the trial erased it. A training path that punished impatience by tearing the fighter’s chest lining on day one was fully useless to ambitious young lords who wanted quick tournament glory.
While the cool, slightly bitter paste of calcined winter-reed pith dissolved beneath his tongue, Seyun recorded the exact minute-by-minute progression of the unbound trial in the cold and exact margin of his Account Book. Breaths one to three: smooth entry along left clavicular guide-line. Breaths four to six: crescent check-valve parts by one hair-breadth. Chest pressure drops by four beats. Breaths seven to nine: full floating lift across upper ribs. Breath ten: unanchored return current rebounds against dry inner tunica. Immediate needle-heat across left pectoralis major.
If Mina ever read this page in Oran, she would scold him for testing an unknown two-hundred-year-old spirit vein diagram on his own chest in a damp cellar. And then she would right away read his ten-breath symptom log three times with her eyebrows knitted together in fascination.
Why had the inner lining of the left chest muscle channel dried out so suddenly on the tenth breath when no external echo met it? Seyun thought through the fluid mechanics of human spirit veins as he kept his slow fifty-six-beat recovery rhythm. He saw the reason clearly.
In a closed, solitary spirit vein loop, the fighter’s own rising breath carried a thin mist of interstitial moisture up from the kidney and spleen spirit veins, lubricating the dorsal turn at the shoulders before dropping back to the belly. In an inward-returning chest like Seyun’s, however, the three crescent nodes beneath the collarbones and chest bone were built like high-pressure lock gates. They opened without a corresponding inward surge of load-bearing pressure from across a Contrast Mark. Then, the sudden drop in pressure flashed the natural moisture of the vessel wall into dry heat.
Without the calcined reed-pith mucilage to restore the stone film along the vessel lining—and without the discipline to stop at the tenth breath instead of stubbornly pushing to the twentieth or thirtieth—a proud initiate would blister the inner sheath of his chest channel within five minutes.
Once blistered, a spirit vein wall cried scar-fibrin as it healed, gluing the delicate crescent valve permanently shut.
“Half of their early initiates ruined themselves in the first month because they treated a lock-gate like a battering ram,” Seyun noted softly. He felt the last trace of dry heat behind his left chest muscle yield to the cool stone salts of the reed-ash. “They thought that if ten breaths hurt, fifty breaths would break through.”
At Ash Reed, he had watched new students make that exact same error every spring during iron-palm and stone-stance drills. Bruising their bone-skin until their knuckles swelled like turnips because they confused self-inflicted tissue damage with martial dedication.
True training was never about how much needless damage you could inflict on your own body out of vanity. It was about understanding the exact load a structure was built to carry, preparing the mortar with the right medicine, and stopping the instant an unanchored vector began to shear.
Seyun wrapped the leftover ounce and a half of Master Uren’s calcined reed-pith ash carefully back into its bitter pine-resin-waxed tissue packet. He tucked it into the safest inner pocket of his wool tunic beside his three copper needles.
It was an art built only for someone who knew how to count the drops of a water-glass in the dark and wait until the structure was ready.
With his left chest muscle vessel cooling steadily under the reed-ash paste, Seyun turned his attention to Article Two on the stone tablet. There, Master Uren defined the five great training realms as experienced through the Answering Spirit vein.
