The carriage was an open buckboard hired from the postal livery at the south gate of Nuoding.
Its team consisted of two sway-backed draft mares with split hooves and yellow coats, their bells muffled by strips of greasy wool.
Behind the driving bench sat four sealed wicker hampers of hardtack and dried mutton, three five-gallon water casks bound in ash hoops, and an iron chest containing the Grandmaster’s specimen jars.
Xiao Wu sat atop the largest water cask, his knees pulled up to his ribs, his scorpion braid trailing over the tailgate into the yellow dust of the southern provincial road.
He had not stopped chewing since they cleared the municipal milestones.
In his lap was a pocket of salted wild plums he had bartered from the gatekeeper’s wife; every two miles he spat a round pit into the roadside ditches with a sharp, pneumatic *pfft* that made the off-side mare flick her ears.
“Nuoding sits in the northern foothills of the Fasi Empire’s border basin,” the Grandmaster said, his voice flat, dry, and competing with the steady, dry grinding of the ungreased iron wheel hubs.
He sat upright on the driving bench, holding the leather reins in calloused, ink-stained hands.
His woolen cloak was thrown over his knees despite the rising summer heat, shielding his thin shins from the gravel thrown up by the team.
“Five hundred miles south,” he continued, glancing at Tang San, who sat cross-legged on the floorboards behind him, her back resting against the iron tool chest.
“We will cross the border into the buffer territory between the Heaven Dou Empire and the Star Dou perimeter reserve.
It is not an imperial park like the Nuoding reserve.
There are no watchtowers, no garrison pikes, and no token gates.
The imperial boundary stones end forty miles north of the outer canopy.”
Tang San did not look up from her hands.
Between her knees lay a square of coarse canvas.
Upon it were arranged nine three-inch bodkins filed from the northern spring steel she had reserved at the Zhen Tie Workshop.
Her right hand held a small horn spoon, with which she was carefully applying a dark, viscous paste to the spiral grooves cut into each dart’s tip.
The paste was an alchemical reduction: six parts Datura neurotoxin scraped from the venom glands she had preserved in the glass vial, two parts powdered charcoal to retard evaporation, and one part rendered mutton fat to ensure adhesion during ballistic flight.
“The rules of engagement change once the boundary stones are crossed,” she said, her voice dropping into the cool, measured cadence of an assassin checking a field kit.
“Entirely,” the Grandmaster agreed, nodding once.
“In the imperial reserves, the beasts are culled to prevent dangerous packs from congregating.
In the Star Dou buffer, natural selection operates without imperial interference.
A seven-hundred-year predator in Star Dou possesses three times the territorial cunning of an equivalent beast in Nuoding.
It does not charge in an open line; it tracks thermal scents, ambushes from dead angles, and strikes when the prey is drinking or defecating.”
Xiao Wu’s plums stopped mid-air.
He looked down from his cask, his large, dark eyes locking onto the Grandmaster’s back.
A faint, razor-thin tension hardened the soft contours of his jaw, his pink lips pressing together until his canine teeth slightly indented his lower lip.
“They aren’t ‘beasts’ like stray dogs,” Xiao Wu muttered, his voice unusually low, losing its bright, bell-like bounce.
“They live where they were born.
Humans dig up their trees, build iron roads through their drinking pools, and call them monsters because they bite the boots that step on their nests.”
The Grandmaster tilted his head slightly, his sharp, deep-set eyes observing the boy’s reflection in the brass rim of the coach lantern.
“Nature is not an imperial court, Xiao Wu,” the Grandmaster said, his tone turning into that of a clinical lecturer dissecting a beetle.
“There are no moral verdicts in the brush.
The tiger does not ask the antelope for an administrative permit before crushing its windpipe; the antelope does not pity the tiger’s starving cubs when it kicks the predator’s jaw to splinters.
The beast hunts because it requires calories.
To assign guilt to either side is to misunderstand the fundamental mechanism of the continent.”
Xiao Wu turned his face away toward the western scrub hills, his jaw clenched tight, his long scorpion braid swaying dead against the dark pine wood of the cask.
He did not reply.
But beneath the coarse fabric of his trousers, the muscles in his calves coiled tight, his soft cloth shoes pressing against the wood until the stave groaned faintly under the static load.
Tang San reached out with her left hand, her cool, pale fingers lightly brushing the instep of his foot.
“Xiao Wu,” she said softly.
The boy blinked, looking down at her upturned face.
Tang San’s dark blue-tinged eyes were clear, steady, and devoid of the Grandmaster’s clinical coldness.
She held up a small, dried plum she had picked up from the floorboards, wiping the grit from its skin with the hem of her sleeve.
“The core is too sour,” she said, her voice smooth and level.
“Eat the meat, discard the stone.
When the road enters the deep forest, you stay behind my left shoulder.
If a shadow drops from the branches, do not look at its face.
Look at its paws.”
Xiao Wu took the plum.
The feral, ancient darkness behind his pupils dissolved like mist under a sudden draft.
A small, sheepish smile cracked the stubborn set of his mouth, and he nodded once, settling his weight back onto the oak cask.
***
Eight days of continuous travel brought them to the frontier station of Baishi—a muddy, miserable garrison outpost built of unpeeled spruce logs, huddled against the base of the southern mountain shelf.
Here, the Heaven Dou imperial highway ceased to exist.
Before them lay forty miles of broken limestone gullies, choked with gray shale, thorny blackberry runners, and sprawling thickets of dwarf juniper.
Beyond the gullies, rising like a colossal, bruised green wall against the southern sky, stood the ancient canopy of the Star Dou Great Forest.
The trees there did not resemble the slender poplars or manicured oaks of Nuoding.
They were primeval titans—ironwood, black cedar, and giant cypress whose trunks were twenty feet thick at the base, their moss-draped branches interlocking five hundred feet in the air to create an unbroken, lightless ceiling that stretched for thousands of square miles into the southern continent.
The buckboard was abandoned at the Baishi livery.
The Grandmaster shouldered a canvas pack containing their essential supplies; Tang San carried the rest within the Twenty-Four Moonlit Bridges at her waist.
They entered the broken limestone gullies on foot at the second watch of morning.
“Our target is specific,” the Grandmaster said, leading the way with an iron-shod ash staff in his right hand.
“Your first ring provided toughness and paralytic neurotoxin.
The second ring must not conflict with these vectors.
We are searching for an organism that possesses two primary characteristics: absolute flexibility and aggressive parasitic propagation.”
“A parasitic plant,” Tang San said, stepping over a cleft in the shale without making a sound.
“Specifically,” the Grandmaster said, “the *Ghost Vine*.”
He stopped at the crest of a shale ridge, pointing his staff toward a narrow, shadowed gorge where a mountain stream vanished into the dark margin of the great forest.
“The Ghost Vine is a predatory botanical variant,” the scholar explained, his eyes burning with familiar, intense academic focus.
“It possesses no independent trunk; it climbs by strangling host trees, injecting microscopic parasitic seeds into the bark.
Once anchored, it drains the host’s cellular moisture within three months, turning the timber into rotten sponge.”
He turned to her, raising two fingers:
“First: its fibers possess the highest tensile limit among continental creepers.
Even a five-hundred-year Ghost Vine cannot be severed by a common iron broadsword without fifteen continuous strikes.
Second: its sap carries an aggressive neurological hallucinogen combined with a localized caustic enzyme.
If attached to your Blue Silver Grass, your *Entangling Bind* will no longer be a passive net; it will become a living, parasitic constriction engine that roots itself into the enemy’s spirit armor, draining their internal energy to feed the growth of additional vines.”
Tang San’s mind mapped the theoretical implications in an instant.
*A self-sustaining energetic loop,* she calculated.
*The more spirit power an opponent outputs to break the initial bind, the more fuel the parasitic seeds absorb to accelerate their cellular replication.
The target’s own cultivation becomes the executioner’s weight.*
“The age threshold?” she asked.
“Six hundred to seven hundred and fifty years,” the Grandmaster said, his jaw tightening into a grim, unyielding line.
“At seven hundred years, the Ghost Vine’s main stem turns a deep, bruised violet, striped with yellow phosphorescent rings that match the Datura’s coloration.
Its thorns grow to the length of a human thumb, curved like hooked scythes.”
He looked into her eyes, his melancholy face heavy with warning:
“The spiritual shockwave of a seven-hundred-year botanical predator is entirely different from a beast.
A beast’s remnant will attempts to crush your sea of consciousness with primal rage; a botanical predator’s will attempts to parasitize your nervous system.
It will seek to take root in your Dantian, using your meridians as soil.
If your will wavers by a fraction of a heartbeat…
you will become a hollow husk, a human stalk sprouting purple vines from every pore.”
Tang San did not flinch.
Her left hand rested naturally over the silent sleeve dart beneath her gray cuff; her right hand rested against the third jade of her belt, where thirty-six steel bodkins and twelve vials of Datura venom lay ready for deployment.
“A plant requires soil to grow, Master,” Tang San said, her voice calm and level as water poured from a bronze pitcher.
“My Dantian is not soil.
It is an iron anvil.
If it enters…
I will hammer it until the root breaks.”
The Grandmaster looked at her for three long seconds.
A rare, fierce smile touched his thin lips, and he turned toward the shadowed gorge:
“Then let us enter the green gate.”
