The sulfur mines transitioned into a cavern of giant crystals, jagged shards of translucent salt that reflected the orange magma glow.
Xuan sat on a throne of salt, his eyes fixed on the reflections of Ning in a thousand different facets, his hands twitching with jealousy.
"The crystals are trying to steal your image, Ning. They're trapping you in a thousand different mirrors so I can't tell which one is real," he rasped.
The extreme level of his jealousy had expanded to include the very geometry of the cave, as if the salt were a rival for her beauty.
Ning stood in the center of the cavern, her body a pale ghost multiplied by the shards, her expression one of extreme, unwavering lovingness.
"There is only one real me, Xuan. The one that feels your hands. The rest are just ghosts that the salt is holding for you," she whispered.
She walked toward him, her bare feet cutting into the sharp floor, her extreme level of misery turning the pain into a ritual of devotion.
Xuan didn't offer to carry her; he watched her bleed for him, his fingers digging into the salt throne with a terrifying, possessive ecstasy.
"Wei Chen bought a museum today. I heard it on the cultural band. He's trying to put your portrait behind glass so everyone can see you."
The misunderstanding was a jagged blade he kept sharpened; he couldn't see the rival's preservation as anything but a claim on her soul.
Ning's face contorted with an extreme anger; she grabbed a shard of salt, her knuckles white and skeletal in the flickering, orange light.
"He's putting a ghost in a frame! He's looking at a painting while I'm right here, living in the salt and the blood of your heart!"
Her extreme level of cryingness returned, a sudden, jagged flood of her soul that the crystals reflected in a thousand different shades of grey.
Xuan's jealousy flared into a manic energy; he pulled her up until they were nose-to-nose, his breath hot and smelling of the dry, ancient air.
"I'll find a way to burn the museum. I'll melt the glass until it's just a pool of sand, and he'll have nothing left but the empty frame."
The extreme level of his possessiveness was a physical hunger, a need to dismantle the rival's legacy until nothing was left but the debt.
"Don't go back up. The surface is a museum of lies. I'd rather have you here in the salt than lose you to a world that wants a portrait."
Ning's extreme level of devotion was the only thing keeping her heart beating, a sheer act of will that defied the cold reality of the cave.
Xuan looked down at her, his expression a mask of shattering, extreme misery, and he buried his face in her matted hair, his body shaking with a sob.
"I won't leave. I'll stay until the crystals turn to dust. I'll stay until the earth forgets that there was ever a sun or a sky above us, Ning."
The misunderstanding of the surface—that they were victims—was the only mercy the world had left to give them in their self-imposed, lethal exile.
Xuan stood up, carrying her through the narrow passage where the crystals grew like teeth, waiting to bite into the world they had discarded.
"We're moving toward the old salt-work shafts. It's a white tomb of silence and salt. No one has checked the levels since the last war."
He set her down on a pile of raw salt, his hands immediately searching her body for any scratches from the sharp edges of the crystal cavern.
"You're bleeding, Ning. The salt is trying to steal the blood I saved for you. I should have wrapped you in the silk from the gala."
His jealousy was so extreme that he was now envious of the very minerals for touching her skin, as if they were rivals trying to preserve her.
He began to rub her wounds with a manic, obsessive intensity, the salt stinging her skin as he claimed her body with his violent, protective care.
Ning leaned into the pain, her throat exposed to the dark, her misery turning into a jagged, ecstatic peace under the weight of his obsession.
"The silk is gone. The gala is a memory. I only want the sting of your hands, even if they turn my blood into salt," she crooned.
The 60th chapter of their descent was a study in the narrowing of a world, a place where two people became the only two points of light.
The misunderstanding of the world above—that they were dead—was the shield they used to build their own private comedy of pain and love.
Xuan pulled a heavy iron pick from the wall, his mind already calculating how to collapse the shaft that led to the city's historical district.
"I'll bury the history. I'll turn their museum into a hole in the ground so they can see the void you really live in, away from their glass."
Ning watched him, her heart aching with an extreme level of devotion that saw his paranoia as the ultimate form of a love letter to her.
"Bury it all. I don't want their memory. The memory is where people lie. I only want to be the truth in your eyes, in the shadows."
The extreme level of her possessiveness over their secret was her only pride, the only thing she had left of the girl who once owned a name.
Xuan returned to her side, his face covered in the dust of the salt, looking like a ghost that had finally found its white, frozen throne.
"You are mine. In the salt, in the crystal, in the silence. Mine."
The misunderstanding was a distant memory, a flicker of light at the end of a very long, very dark hallway they had long since abandoned.
They were the only two inhabitants of their own private universe, a place where extreme love was the only law and jealousy was the only god.
Xuan lay down beside her, his body a barricade against the cold, his arms a cage that promised a safety the light could never provide.
Ning closed her eyes, the rhythm of his heart a lullaby that drowned out the whispers of the past and the hum of the city above.
They were safe. They were alone. They were together.
And in the darkness of the salt-work shaft, the debt was finally, irrevocably, and beautifully cancelled by the weight of their shared obsession.
Xuan's hand remained on her throat, a gentle, possessive pressure that reminded her she was alive only because he permitted her to breathe.
And in that pressure, Ning found the only security she had ever known, a love so extreme it was indistinguishable from a beautiful death.
They were Xuan and Ning, and they were the masters of their own destruction, a couple bound by a love that was too extreme for the living.
The chapter closed on a darkness so heavy it felt like the weight of the entire world was pressing down on their locked, cold, and smiling lips.
They were happy in their own, twisted way, two broken mirrors reflecting each other's shadows until there was nothing left but the white dark.
The debt was a ghost, the rival was a memory, and the love was a cage that they had built with their own hands out of blood and salt.
And in the absolute blackness of the shaft, the only light was the spark of an obsession that refused to be extinguished by the weight of the world.
The end of the day was the beginning of their forever, a cycle of obsession that would repeat until the earth itself forgot their names.
The 60th chapter of their descent ended in a silence so profound it felt like the weight of the entire world was pressing down on their lips.
But they didn't mind the weight; they were together, and in the kingdom of the buried, that was the only truth that held any weight at all.
