The new axe head rang.
Jin Cheol looked up with the tongs still in his hand. The iron had not touched the quenching water yet, but it was trembling on the anvil, and not with the dull complaint of a badly placed hammer stroke. Something had begun deep inside the mountain, climbed the smithy floor, and reached the metal.
“Father. Are they blasting at the quarry again?”
His father, sorting charcoal beside the bellows, tilted his head to listen. “Nobody’s working today. And powder shakes the ground first. That’s coming down from above.”
Before he finished, every pair of tongs hanging under the eaves jangled at once.
Jin Cheol did not put the axe head back into the fire. The iron wanted water now — the edge had ripened past persimmon and was going the red of a cherry, and one breath’s delay would change its hardness for the rest of the blade’s life. He looked at the mountain, then at the trough, and shifted his grip.
“Staring the iron down again.”
Han Yeonhwa stood in the doorway with the sun behind her and a bolt of cloth in both arms, the one she had spent half a year choosing for their wedding quilt.
“I’m reading the color.”
“The axe will harden out of fright, then.”
She spread the cloth over the workbench. Jin Cheol found the single crooked weft and pinned it with a finger. “Here.”
“Eyes that good had better remember the color of my ribbon on the wedding day.”
“Red.”
“Last time you said indigo.”
His mother’s laugh came out of the inner room. Yeonhwa let herself be beaten and flicked the end of the cloth against his arm, and on any other day he would have laughed with her. But the iron on the anvil trembled again, and this time the pulses came evenly spaced, like a shuttle crossing a loom.
Thump. Three breaths. Thump. Two breaths.
The interval was closing.
He drew the axe head out and lowered it into the trough. White steam went up, and under the hiss of the quench ran the mountain’s note; where the two vibrations crossed, the surface of the water stitched itself into fine diamonds.
“Yeonhwa. Stay inside.”
“Why?”
The cheering started at the upper end of the village. Children ran toward the valley shouting that people were flying, and Jin Cheol’s father stepped over the threshold to see. A man in white stood in the middle of the blue sky with nothing beneath his feet, and across the gap from him stood a giant with a black saber laid over one shoulder. In the road an old man went down on his knees and said the name the way other people said the name of a season: the Sword Saint of Mount Hua, Wi Sohyeon.
The swordsman saluted first, fist to palm. From that distance his voice arrived as though he were speaking at their ears.
“Ten years we have argued this, Brother Namgung. The sword leads with intent, the saber with momentum. Let us find out today which of us heaven agrees with.”
Namgung Tae laughed. “If heaven has ears, it is going to get an earful.”
Neither of them carried any killing intent. They sounded like old friends settling down over a game board, and it was the ease of it that made Jin Cheol afraid.
Then the sword came out of its sheath.
No one saw the first exchange. The pines on both slopes went down in the same direction, and only afterward did the sound arrive, late and enormous; the cheering turned into screaming; at the second exchange the cliff let go of its stones, and Namgung Tae came up through the falling rock with his saber and left a white crescent hanging where the air had been.
Jin Cheol was not watching the duel. He was watching the smithy posts, the water in the well, the tongs under the eaves. Strike a hollow bar and its note swells at particular places along its length; the whole mountain was doing that now, a bell with the valley for a mouth. Each clash did not fade. Each clash was added to the last.
“We have to get away.”
He had his father by the arm.
“Where to?”
He had no answer for that. The ground rang. The air rang. The mountain rang.
He started for the valley, and Yeonhwa caught him by the belt from behind.
“Have you lost your mind? What are you going to do up there?”
“Make them stop.”
“You think your voice carries that far?”
“Iron does—”
He took the plowshare down from the smithy wall and brought it against the anvil. A clean clang went out over the roofs. He struck it again. Villagers turned; the two men in the sky did not. They had the power to move a mountain and no reason on earth to listen to iron ringing beneath it.
“Get down below the village!”
He struck a third time and waved both arms at the spectators. The miller’s wife hesitated with her child against her shoulder. The tavern keeper only laughed.
“Will we see the like of this again in our lives? The great heroes know their own business.”
“The cliff is throwing the sound back. It is going to come down.”
“And which of you knows this mountain better — you, or them?”
One old man pulled his two grandchildren against his hip and started downhill. The rest could not take their eyes off the sky. Each time the Sword Saint opened his blade, light scattered off it like petals; each time the Saber King swept the petals out of the air, the hum went in under everyone’s ribs and stayed there. It was beautiful. That made it harder to flee, and Jin Cheol stopped arguing with a spectacle and ran for the meeting hall.
Yeonhwa did not stop him this time. She sprinted down the opposite alley.
“I’ll clear the houses by the stream. You wake the upper village.”
“Don’t come back to the smithy.”
“Since when do you give me orders?” She snapped it at him and nodded in the same breath. “Stay alive and nag me later.”
The bell rope broke after the first pull. The vibration coming down off the mountain had already drawn the nails halfway out of the bell frame, so Jin Cheol put his shoulder into the bell itself, and the mass of metal tilted and gave one heavy, ugly warning. Doors opened along the lane. He pushed three children onto the stream path and turned to carry a lame old man on his back, and the old man dug in his heels and said he would not go anywhere without his ox.
“You can buy another ox.”
“Without that beast we die this winter!”
Jin Cheol broke the stable bar. The ox went into the alley at a panicked run and the old man went after it, cursing him the whole way.
Then his mother called him from the smithy.
At the tip of Wi Sohyeon’s sword the light branched open like a plum flower, and Namgung Tae took it obliquely on the saber, and one strand of white came off wrong and raked the valley wall.
The cliff split first.
Jin Cheol felt the catastrophe in the soles of his feet before his head had any part in it. All afternoon the vibration had been stacking, layer on layer; now it stopped. Heated iron goes quiet in exactly that way in the moment before it breaks.
“Down!”
Yeonhwa had come back through the alley behind the wall — of course she had, with his parents still inside — and she was already in the outer work yard where the old loom stood. He shoved her flat against the far side of it and reached for his father. His father was at the inner door with both arms around his mother. The forge stood between them.
The world went white.
Pressure came before fire. The smithy wall folded like paper, nails tore loose, roof beams went past like thrown spears. Jin Cheol was hurled behind the quenching trough, and its iron-bound sides crumpled and split the blast around him while the water it had held came over his right arm and back, boiling.
Only after sound itself had gone did the pain arrive.
He opened his mouth in the mud and took in ash instead of air. The skin of his right arm had lifted in dark red welts and the fingers would not answer. He clawed at the ground with his left hand and dragged himself out from behind the ruin of the trough.
Where the smithy had stood there was a black crater.
“Father.”
Nothing came out.
Yeonhwa lay at the edge of it with her left hand pinned under the fallen loom, still holding the cloth. Jin Cheol crawled to her and pushed at the beam and it did not move; he found a bar of iron in the wreckage, wedged it under, and heaved until she could tear her hand free with her teeth set. Her ring finger and her little finger had been crushed past recognizing.
“Your parents first.”
She got the words out in pieces. He bound her wrist with a strip of the wedding cloth instead. The bleeding would not stop, and the living had to be tended before the dead, and accepting that took an instant longer than his whole life had taken.
Below the smithy, the people who had run at the sound of his bell were coming back. The miller’s wife hauled stone with her child still on her back. The old man whose ox he had loosed smothered embers with a bloodied shovel. Jin Cheol left Yeonhwa with them and went down into the crater.
He found his mother’s hairpin where the inner room had been, the tip melted, still hot enough to stick to his palm. Half of his father’s leather apron lay pinned under a beam. He threw himself at the beam and his right arm folded and put him on the ground.
“Get the living out first!” somebody shouted.
“They’re here.”
He took hold of the beam again. Nobody could bring themselves to tell him that nothing recognizably human was left under it. Four of them lifted it together, and beneath it were fragments of blackened bone. Jin Cheol wrapped them one by one in cloth and did not ask which had been his father and which his mother. Nobody in the village could have answered.
The houses along the stream had emptied in time. The three children came back alive. When that comforted him he felt he had betrayed his parents, and when it did not comfort him he felt he had turned the choice that saved them into a lie, and unable to hold either feeling he went on sifting the ash with one hand.
Near sunset the two masters came down. Not a fold of either man’s robe was out of place. Namgung Tae looked over the crater and the bodies laid in a row and clicked his tongue.
“The valley gave back more than I allowed for.”
He untied the purse at his belt and set it on a stone, where it landed with weight.
“There is enough there to rebuild the houses and something over. The Namgung name pays what it owes.”
Wi Sohyeon crouched down in front of Jin Cheol, who was gray to the eyelashes with ash. There was real sorrow in the man’s face, and because of it Jin Cheol waited to hear what he would say.
“I am sorry for your loss.” Wi Sohyeon said it quietly. “What we understood on that ridge today will keep a great many people alive in the years ahead. Their deaths will not be wasted on the martial path.”
Jin Cheol did not let a word of it go by. It was a verdict with the crime and the sentence already entered, one the dead could not testify against and the living could not appeal.
“If I go to the magistrate, may I give him your names?”
Namgung Tae’s eyebrows went up.
“May the record say it was a contest between two great heroes?”
Wi Sohyeon was silent a moment. Then he looked at the burned arm and said, “I will not stop you recording the truth. Only do not let anger blur it. The resonance was not something either of us could have avoided.”
Jin Cheol pointed at the nails bent around the lip of the crater, at the stones shorn away on one side and untouched on the other.
“Who decides what could not be avoided?”
For the first time, Wi Sohyeon’s gaze stayed on his face. He did not take offense. If anything he answered more seriously than before.
“A man who has come far enough along the path knows what force he is able to carry.”
“Then who carries what you couldn’t?”
Namgung Tae came between them. “You talk a great deal for a man in your condition. There is gold enough there for a physician.”
Gold answered again, in place of either of them.
“See to your treatment,” Wi Sohyeon said. “Do not let resentment cost you the arm as well.”
They were gone before the sun touched the ridge. Nobody stopped them. It did not occur to anybody that they could be stopped.
Yeonhwa was carried off to the physician and the villagers began gathering their dead, and Jin Cheol sat alone in front of the purse on the stone. He drew out one piece and the evening light ran across it like oil. It was more than his mother had held in her hands in her life. It was more than his father could have saved out of hundreds of hoes and sickles.
He did not throw it into the river. He tied the mouth of the purse shut left-handed and put it inside his coat, because you do not destroy what a criminal leaves behind at the scene.
High on the mountain the sword scars and the saber scars took the last of the light and shone. Jin Cheol measured them with his eyes, from where each wound started to where it ended.
“I’ll melt your blades down with this.”
There was no one to hear him.
