Five miles north of Cloudford Town, the mountain track narrowed into a cleft of jagged black granite known as the Iron-Slag Ravine.
The air here was twenty degrees colder than the river valley. It carried the sharp, stone tang of sulfur, crushed hard coal, and scorched river sand. Deep within the ravine, where a mountain torrent rushed over a boulder-strewn water chute, the darkness was pushed back by a pulsing, orange-red glare that turned the overhanging pine needles to rust.
Cloudford Mountain Forge had stood at the throat of this ravine for forty years.
It wasn’t a town forge shop with neat rows of plowshares and horseshoes. It was a sprawling, soot-blackened compound built from giant stone granite blocks, roofed with corrugated copper sheets greened by decades of acid smoke. High above, a thirty-foot waterwheel turned with a groaning, rhythmic shriek. It drove a five-hundred-pound iron trip-hammer that shook the bedrock with every drop.
Pei Jing stepped across the threshold of the open yard, the heavy wicker basket of pig-iron billets resting easily against his shoulders.
Inside the central hearth-shed, the heat hit his face like a blast from an open oven.
A man stood before an eight-hundred-pound horn anvil. He held a pair of five-foot iron tongs with hands that looked like split firewood.
Master Mo Tie was sixty years old, with a barrel chest broad enough to shield an ox and shoulders knotted with cords of grey-haired muscle. His left ear was missing its upper lobe—snapped away decades ago by an exploding melted rock waste bubble—and his face was mapped with pale burn scars that puckered his leathery, walnut-colored skin. He wore only a heavy apron of cured steer rawhide, blackened with grease, over thick hemp trousers.
In the tongs he held a glowing orange metal bar. It hammered it into the curved leaf of an iron wagon spring with an eighteen-pound sledge.
Clang. Clang. Clang.
Each blow was metronomic, delivered with the casual, heavy driving force of a man whose joints had fused with iron.
Mo Tie didn’t look up when Pei Jing entered. He struck the metal bar five more times, thrust the cooling metal into a barrel of dark water with a violent, roaring hiss. Then he dropped the tongs onto the anvil block.
“The forge is closed for commercial trade,” Mo Tie growled, his voice rasping from forty years of inhaling coal dust. “If the Pei Clan wants twenty more picks for Shaft Two, tell Hongcheng to bring silver up the mountain next month. I don’t hammer scrap for promissory notes.”
Pei Jing walked forward, letting the wicker basket slide from his shoulders.
The six twenty-pound billets of South Hill pig iron settled onto the flat stone slabs with a dull, heavy thud.
“I’m not here for mining picks, Master Mo,” Pei Jing said.
Mo Tie wiped his forehead with the back of a blackened forearm, squinting through the heat shimmer at the youth standing before him.
“Another clan brat,” the smith spat. He grabbed a wooden gourd of sour rice beer from an anvil bracket and taking a long swallow. “Every spring and autumn, some boy from the town comes up here with five silver coins, asking for a three-foot scholar’s dress sword so he can impress the tavern girls in the bazaar. Go back to town, boy. Go practice calligraphy. Swords are vanity. Only plows and axes feed people.”
Pei Jing reached into his cloak and withdrew the sealed bamboo tube.
He untied the oiled hemp cord, slid off the cap. Then he pulled out the roll of thick mulberry paper. He stepped up to the heavy timber layout table beside the hearth. He rolled out the drafting sheet. He anchored the left edge with an iron cooling weight and the right edge with the Black Mountain Whetstone from his belt. His thumb stroked the cool dark rock groove, noting the contrast between the stone’s freezing stone thickness and the blast of the hearth.
“Look at the draft before you price the labor,” Pei Jing said.
Mo Tie snorted, muttering a curse under his breath. But forty years of metalworking obsession pulled his eyes toward the paper.
He leaned over the table, his single intact ear cocked, his calloused hands resting on the edge of the timber.
The sneer on his scarred face slowly dissolved.
His eyes tracked the bold, black lines of the brushwork: the three point two feet overall length, the massive tiny spine tapering along an unbroken straight line, the four-inch flared chopping head ending in a heavy sixty-degree chisel point, the twin parallel fullers carved deep along the blade’s waist, and the exact weight math written in the margin: Twenty-two point zero pounds.
“What kind of unhinged tool is this?” Mo Tie muttered, his thick thumb tracing the outline of the flared chopping tip. “This isn’t a royal broadsword. It has no sweeping belly for drawing cuts. It’s a headsman’s cleaver stretched into a poleaxe.”
“It’s designed to sever iron-banded truncheons, break spear shafts, and crush copper-riveted armor,” Pei Jing said. “It doesn’t need to draw across silk. It needs enough physical mass to cleave through bone on impact without bouncing, and enough twisting stiffness to survive a block from an iron mace.”
Mo Tie looked up, his one eye narrowing with sudden, hungry intensity.
“You drew this?”
“I did.”
“A blade this heavy needs twelve tiny fractions of an inch of solid steel at the blade collar,” Mo Tie muttered, leaning closer. “If you cast it from ordinary pig iron, it will snap like dried willow the first time you strike stone. If you make it from soft forged iron, the edge will roll into a lead sausage after two chops. To make this beast live, you need hard steel core steel wrapped inside high-hard dark metal shock cladding. Three hundred folds minimum. And then the cool—an edge this wide will warp like a fried fish if the salt water isn’t balanced to the exact ounce.”
“I brought the metal,” Pei Jing said, pointing his chin toward the wicker basket. “One hundred and twenty pounds of virgin pig iron from the South Hill deep vein. Four point two percent natural hard dark metal content, smelted with hard coal coke before the river was locked.”
Mo Tie walked over to the basket. He knelt, picked up one of the twenty-pound billets. Then he struck it against the corner of the anvil horn.
Ring.
The sound tone was sharp, clear, and sustained for four seconds.
Mo Tie rubbed his thumb across the fractured crystal-clear surface of the iron billet, sniffing the grey powder that stuck to his skin.
“Good ore,” he murmured. “The South Hill deep shaft has the purest hard dark metal in three counties. But good ore doesn’t hammer itself.”
He dropped the billet back into the basket, stood up, and looked Pei Jing up and down with a cold, measuring stare.
“A twenty-two-pound blade needs three men: one smith to direct the folds, one striker on the sledge, and one man on the great box bellows to keep the hearth at twelve hundred degrees. The Black Tiger Gang has blocked the mountain road. My two apprentices ran off to the country capital three days ago because Hu Biao threatened to break their kneecaps if they forged a single blade for your clan.”
Mo Tie pointed a thick, soot-crusted finger toward the rear of the hearth.
There stood the great box bellows.
It was six feet long, three feet wide. It was built from dense, four-inch white oak planks bound with forged iron bands. Two thick hickory push-poles projected from its face. Inside, double-acting pistons of oxhide and wild pig bristles tightly packed twenty cubic feet of air per stroke. That forced it through underground copper pipes directly beneath the hard coal hearth.
“That bellows has an eighty-pound clockwork pushback on every push and pull,” Mo Tie said, his voice flat as granite. “To melt hard dark metal iron without losing the carbon, the coals must stay at blinding yellow heat. If the airflow drops for thirty seconds, the melted rock waste solidifies. If you pump too fast, the air oxidizes the steel into useless scale.”
The smith crossed his massive arms over his rawhide apron.
“You want me to forge your headsman’s cleaver? Take those two hickory handles. Four hours. Not a minute less. If your arms shake, if your tempo breaks. Or if the hearth flame drops from white to orange, I kick your pig iron into the ravine and you walk back to Cloudford empty-handed.”
Pei Jing looked at the oak box bellows.
Then he reached for the collar of his grey homespun robe.
He untied the hemp cord at his waist, slipped the robe from his shoulders, and laid it neatly across a timber stool.
Mo Tie’s eyebrows twitched.
Across Pei Jing’s back was a nine-inch level scar. A pale, raised silver seam across his shoulder blades where eight days ago a serrated cleaver had split through his flesh. The wound was fully closed, knit together by dense, limit-break muscle fibers that pulled tight like braided hemp cord. Beneath his skin, the long muscle tissue of his back and flanks moved with the distinct, corded texture of coiled bowstrings.
There was no excess fat on his frame. Every tendon was clearly said clearly, running like steel wire beneath pale, hardened skin.
Pei Jing walked over to the bellows station.
He planted his feet on the flat stone slabs, three feet apart, sinking his balance point two inches. His knees unlocked, shifting into the Python Tendon-Stretching Stance.
He gripped the twin hickory handles with both hands.
The wood was dark, worn smooth by the sweat of a hundred smiths, grooved with the grip of heavy calluses.
Push.
The first pushback was brutal. The eighty-pound oxhide piston resisted the stroke, air compressing against the copper nozzles.
Pei Jing didn’t push with his triceps or chest.
He rooted his heels into the stone. His gluteal muscle tissue and lower-back erectors took the load, transferring the striking force through his broad back muscles into his forearms.
Chuff.
A blast of tightly packed oxygen roared into the deep hard coal bed. The dull orange embers flared into a blinding crimson ring.
Pull.
The reverse stroke was equally heavy, the empty pocket chamber pulling against air pressure.
Pei Jing drew the handles back using his rhomboids and scapular bone hooks. His breath exhaled through his nostrils in a slow, rhythmic hiss.
Chuff.
The coals erupted. A tongue of bright yellow-white flame shot six feet into the copper hood above the hearth.
Push. Pull.
Chuu-chuff. Chuu-chuff.
The rhythm was metronomic: one second forward, one second back. Thirty strokes per minute. Exactly eighteen hundred strokes per hour.
In his eye vision, the pale monospace ledger surfaced against the glare of the coals:
Mo Tie stood five paces back, his arms still crossed, watching the youth’s stance.
At first, the smith expected the boy’s shoulders to hitch within twenty minutes. An eighty-pound pushback was manageable for a strong farmhand for half an hour. After forty minutes, muscle burn piled up in the shoulder muscles, the back arched, and the strokes became shallow and jerky.
One hour passed.
The heat streaming from the open hearth reached three hundred degrees Fahrenheit five paces away. Sweat poured from Pei Jing’s forehead. It ran down his ribs and his back scar. It hissed as it struck the hot flat stone slabs beneath his boots.
Yet the handles didn’t falter.
Chuu-chuff. Chuu-chuff.
Pei Jing’s breathing was terrifyingly steady. His ribs swelled and tightened with the slow, even rhythm of a sleeping animal. His spine remained straight, his pelvis locked, the motion driven entirely by the rhythmic stretch of his Achilles tendons and lower-back muscle tissue.
The flame in the hearth didn’t waver. It rose to a blinding, roaring column of blazing bright white heat, lighting up every rafter in the cavernous forge.
Two hours struck.
The ledger in his vision updated:
Mo Tie walked over to the timber layout table. He picked up his twenty-four-pound master sledge, hefting it in his right hand.
He looked at Pei Jing. Then he looked at the white-hot core of the hard coal fire.
The smith spat into the ash pit, a dry, approving grin breaking across his scarred face.
“Alright, ledger boy,” Mo Tie roared over the thunder of the coals. “Keep that air flowing! We put the first billet in the fire now!”
