Side Story: The Black Object Sexual Art
— Plop, plop! This sealed chamber blocked out all light and sound from the outside world. The only things the prisoner inside could perceive were the sound of droplets striking her forehead, their cold touch, and the steady rhythm of her own heartbeat.
— Thump, thump. The prisoner stood bound by ropes to a heavy metal ring fixed to one wall. Her upper body was especially restricted, allowing just enough movement to relieve herself into the chamber pot at her feet. The door to this sealed room opened only once a day, when the jailer performed the bare minimum to keep her alive and checked whether she still drew breath.
— Clack! Creaaak! With an unpleasant noise the door swung open. Instead of the light the prisoner longed for, only the jailer’s presence briefly entered the cell. With uncanny precision, he removed the chamber pot, shoved in a large, long block of black-bean tofu, and withdrew, closing the door without a single misstep. The prisoner’s sole task was to lick the tofu until it dissolved enough to swallow, then spit the remainder into the pot.
“Haaah……”
— Slurrrp… Once again her jaw refused to obey, and she failed to chew the tofu properly.
— Lick, lick… Hunger grew worse with each passing day. Like precious rain, she eagerly lapped at the black-bean tofu. After swallowing the salty, musky mass that resembled a man’s seed, she tilted her head upward as best she could to catch the falling dew and quench her thirst.
— Drip, drip…
— Lick, lick! Once a supreme master whose dantian had been shattered, the nun Hyeon So thought that today, like every day before it, would simply pass in the same monotonous suffering.
— Clack, creaaak! Thud! The cell door opened to an unfamiliar rhythm. A man whose presence dwarfed the jailer’s stepped inside and shut the door behind him.
— Step, step! “W-who……?”
In answer to her question, an old, sinister voice echoed through the chamber. “You have no need to know that.”
The old man placed his hand on the nun’s bare thigh—unclothed save for her restraints—and forced her legs apart. “Hngh! W-what are you doing!”
Though she had walked the demonic path, she had never once experienced intercourse. Her flustered voice died within the sealed room. “Kuhuhuhuhuh! So you were once a supreme master, little nun. The Young Cult Lord has bestowed you upon me as a living treasure. I shall cherish you well.”
“Young Cult Lord? Does that mean this is the Heavenly Demon Cult? And you call me a treasure!?”
For a moment she raised her voice, believing she had been betrayed by the Heavenly Demon Cult, but the old man’s cold reply left her speechless. “Kuhahahaha! Do not lump our cult together with those fools of the Heavenly Demon Cult who know nothing of sex.”
With a faint trace of anger, the old man stopped speaking and removed his own trousers. — Rustle, rustle! A powerful fishy stench and the odor of rot spread from the direction of his manhood.
“Ugh! What is this!” “Spread yourself obediently. You might get hurt!”
— Stroke, stroke! The old man caressed the woman’s groin as though it were precious, then suddenly drove his eight-inch rod mercilessly into her dry entrance.

“Kuaaaagh! Hngh, ugh!” “Oh? A fifty-year-old woman’s maiden blood. Truly a rare delicacy. Slurp.”
After tasting Hyeon So’s virgin blood on his finger, the old man thrust even more vigorously, clearly delighted. “Hngh! S-stop! What did I ever do wrong……?” “Your cunt squeezes so tightly! It’s exquisite! I must add ‘possessing a delicious cunt’ to your list of crimes!”
Alas, stripped of her martial arts, Hyeon So had no strength or means to resist the old man.
— Slap! Slap! “Kuaaaagh! At least be gentle!” “Your sinful tongue is too noisy!”
— Smack! The old man’s merciless palm struck her breasts. She could do nothing but sob. “Hngh, ugh! Hngh, ugh!” “Even your cries are splendid! Hahahahaha! Scream louder, you wench!”
— Slap, slap! — Thud! Thwack! Thud! “Ugh, hngh!”
Now the old man beat not only her breasts but every exposed part—her belly, cheeks, arms, and legs. Yet his technique was so perfect that, despite the agony, not a single scratch appeared on Hyeon So’s body.
The old man’s name was Dong Goman. He was the Fourth Elder of the Sex Demon Cult. Having mastered the Black Object Color Art to its peak, he had reached the supreme demonic realm without losing his sexual function. However, due to the heart demon acquired during his training, he was known to desire only the darkened brown genitals and anuses of aged women—an old monster.
Yet the rumor that he sought only discolored flesh was a falsehood spread by those envious of his achievements. As a man, he naturally did not dislike the pink, luscious flesh of young women. His preference simply required that the owner of such tempting flesh be an “old woman.”
Thus, although he appeared to sadistically torment the aged nun, his concentration at this moment surpassed even the life-and-death battles fought by supreme masters on thin ice. When the Young Cult Lord had given Hyeon So to him, the only demand was to extract information about the orthodox sects and the Heavenly Demon Cult through the suspected spy. Whether by torture or persuasion, he had to obtain the necessary intelligence quickly. At the same time, Dong Goman intended to break the inexperienced woman during the process and claim her as the lifelong partner he had long awaited.
If the dantian-destroyed woman stubbornly resisted to the end, she might be discarded at any moment. That urgency colored Dong Goman’s unorthodox caresses.
His impatient nature and bizarre tastes stemmed from a tragic past. The Black Object Color Art, his secret technique, required absorbing evil qi from the womb of a dead cow at the first stage. From the second to seventh stages, one alternated between absorbing life qi from living women’s wombs and evil qi from corpses. Already vicious, the method grew even more grotesque from the eighth stage onward, for it demanded intercourse with a “living jiangshi,” something only the long-vanished Blood Demon Cult had been able to produce.
In his youth, Dong Goman had used every means available to obtain one of these rare living jiangshi. Through years of one-sided union with it, he finally succeeded in mastering the Black Object Color Art.

It was only natural that his taste for discolored female skin and flesh originated from that jiangshi. On the very day he reached completion, a tragedy for him—and heavenly fortune for the jiangshi—occurred.
— Crackle, sizzle! As usual, the thirty-five-year-old Dong Goman poured his thick, murky fluid into the jiangshi. Suddenly the creature’s entire skin split open and was engulfed in radiance. Possessing a low but human-like intelligence, the jiangshi smiled faintly for the first time since becoming a jiangshi, overwhelmed by the hope of finally being liberated from its unparalleled lust and achieving enlightenment.
“N-noooo!” Thinking this would be his final act before reaching completion, Dong Goman thrust desperately into the jiangshi’s genitals. An unprecedented phenomenon in a thousand years of murim history unfolded.
— Whoosh! — Shaaaa! All the evil qi enveloping the jiangshi was sucked into Dong Goman’s manhood. The hideous cracked skin and the lewd undergarments he had dressed it in crumbled like sand beneath where the jiangshi sat.
“!?”
And the jiangshi regained her original sanity, the martial arts she possessed at the time of death, and her former beauty. The naked former jiangshi had died in her mid-twenties at the peak of her beauty; that beauty had now returned in full.

“I-it’s back! My body! My body has returned! Waaaaah!”
“Aaaah! Nooo! Kuaaaagh!”
The beautiful female master embraced her restored body and wept loudly, while Dong Goman’s wail over losing the bluish-skinned jiangshi that had been his everything echoed through his house for a long time.
After the uproar subsided, the woman—formerly the jiangshi—raped him in the name of revenge and even bore him an unwanted child. Night after night, while being milked dry, Dong Goman swallowed bloody tears and made a vow.
‘Sob…… I prefer the discolored flesh of old women! That damned bitch! Just wait until she grows old!’
“What are you doing! Hurry up and put it in!”
Despite his daily resolve, heaven remained indifferent and never granted him the chance for revenge. “Darling♡ I love you~♡” “Kuaaaagh! Get away from me!”
By actively utilizing the special abilities of Dong Goman’s Black Object for decades, she had instead grown younger, recovering the fresh appearance of a woman in her early twenties. “Kuaaaagh!”
With such a painful past, it was inevitable that Dong Goman came to crave the discolored flesh of old women along with their maternal yet passive attitude during intercourse. Thus he clung to Hyeon So with even greater desperation.
“You are my one and only fated partner……” “Kuh! You insane demonic bastard! Hngh♡”
So the union of the two demonic figures inside the cell showed no sign of ending—until the young woman who claimed to be Dong Goman’s wife broke down the door and beat his back until it burst.
‘Ah, a life without regret. Even if I die, I have no complaints!’
Thus Dong Goman was dragged home by the ear, where he was milked dry until his symbolic black object lost all color.
