The Primordial Inner World was a realm of breathtaking, terrifying potential. Mountains of raw, uncut obsidian scraped against a sky swirled with the Ancestor's nascent divine will. Rivers of liquid starlight flowed through valleys where his younger children tested their monstrous abilities, their laughter echoing like distant thunderclaps. It was a divine cradle, a forge for gods, but it lacked a warden.
Niu, in her stable within the Citadel, felt the call. It was not a sound, but a deep, resonant pull in her very blood, a thrumming echo from the strand of Lu Tian's soul branded into her hip. The new universe inside her Master sang to the piece of him she carried. A soft, concerned low escaped her lips. The Young Lords were in there. They needed tending. They needed milking. They needed a caretaker.
She plodded to the spatial tear he had left open, her large, docile eyes fixed on the chaotic beauty within. Without fear or hesitation, driven by a primal instinct to nurture and obey, she stepped across the threshold.
The moment her hooves touched the soil of the Inner World, the reaction was instantaneous and cataclysmic.
The world itself recognized her. The strand of the Ancestor's soul within her flared like a green sun, acting as a perfect conduit. The raw, unformed primordial energy of the new universe, which answered only to Lu Tian, saw her not as an intruder, but as an extension of its creator. It flooded into her.
It was not a violent invasion, but a glorious, overwhelming infusion. Vast, boundless vitality, the very stuff of creation, poured into her simple hucow body. Her Steadfast Ox Body, designed for endurance and production, underwent a terrifying apotheosis.
Her bones cracked and elongated. Her muscles swelled with cosmic power, knitting and expanding until she towered over the landscape at twenty feet tall. Her fair skin, once soft and human, tightened over a frame of immense, sculpted muscle, retaining its hue but becoming as tough as spirit-forged steel. The hands that had been used for milking remained surprisingly human, dexterous and capable, but her feet and legs transformed completely, becoming powerful, cloven-hoofed pillars capable of stomping canyons into existence.
From the base of her spine, a long, powerful tail tipped with a tuft of silken hair swished into being. Upon her head, two magnificent, curving horns of polished celestial gold grew forth, thrumming with the world's energy.
And on her chest, the four udders that had sustained the Dynasty swelled with the universe's vitality, each now a font of milk that glowed with the light of newborn stars, a potent elixir that could nourish divinity.
Her mind, already simplified to its core functions, was rewired by the world's will. Language, already a distant memory, was burned away entirely. She could now only communicate in deep, melodic groans and lowing that carried profound meaning and comfort to any who heard them—the universal language of a nurturing world-spirit. She was no longer Niu, the hucow. She was the World-Heart Bovine, the Guardian Minotauress.
She saw the chaotic play of the young heirs—Lu Bao's volcanic rage, Lu An's toxic miasma, Lu Gen's immovable stubbornness. A soft, commanding groan rumbled from her chest, a sound that carried the weight of the world's order. The children paused, turning to look at the new, towering presence. They felt her authority, not as a threat, but as a calming, nurturing power. She was part of the world, and the world was part of their father. She was to be obeyed.
Lu Tian felt the shift within him immediately. The sensation of a new, immense power stabilizing his Inner World was intoxicating. He willed himself inside, appearing in a flash of green light.
He looked up. And up. And a slow, predatory grin spread across his face. Before him stood his transformed fourth wife, a goddess of nurturing and strength, a being of his own creation, literally shaped by his soul and his world's energy.
"Magnificent," he breathed, his goblin instincts screaming with avaricious delight. He floated up until he was level with her face. Her large, bovine eyes, now the color of molten gold, looked down at him not with recognition, but with pure, worshipful adoration. She saw him not as her husband, but as her God. The source of all.
He snapped his fingers. Using the world's energy, he clad her immense form in a garment that suited her new role and his own tastes: a bikini of shifting, living cow-print silk that seemed woven from the night itself, highlighting her powerful form and the four glowing udders of cosmic milk.
He reached out and wrapped a hand around one of her golden horns, giving it a possessive tug. She let out a sweet, submissive groan and nuzzled his hand with her massive face, the gesture threatening to create a minor hurricane.
The sight of this mighty creature, this guardian of a universe, so utterly devoted to him, shattered the last of his restraint. His goblin nature, his desire to claim and dominate the most powerful things, surged forth.
He guided her to the side of a mountain that served as the foundation for a nascent, crystalline castle. "Bend," he commanded, his voice a low thrum of absolute authority.
She obeyed without question, leaning her massive forearms against the cool crystal wall, presenting her immense, powerful backside to her God.
Lu Tian, still levitating, grew in size himself, his power within this world absolute. He was still smaller than her, but his will was law. He placed one hand on the impossibly muscular curve of her waist, his fingers digging into the skin-tight hide. His other hand tangled in the hair at the nape of her neck.
Then, he claimed his guardian.
The act was a tempest. His shaft, empowered by his Ascendant Soul realm cultivation and his status as this world's deity, was a weapon of divine proportion. It pierced her honey pot with the force of a falling star, stretching her to her very limits. Her sweet groans turned into deep, resonant cries of overwhelmed ecstasy that shook the very leaves on the world-tree sapling growing miles away.
He was not gentle. He was a force of nature ravaging another force of nature. Her stomach deformed with each thrust, a visible outline of his monstrous member distending her abdomen from within. He was not just mating; he was reasserting his ownership, imprinting his will upon the very heart of the world he had created. He was the God, and this was his titaness.
For days and nights within the Inner World, the storm raged. The heavens swirled with their combined energies. The children, sensing the divine union, stayed wisely clear, soothed by the rhythmic, world-shaking groans of their caretaker.
When it was over, the Minotauress slumped against the castle wall, her body thrumming with spent power and absolute devotion. Lu Tian, hovering before her, looked upon his work. She was perfect. His most beautiful and terrible creation.
He patted her flank. "Good girl," he said, his voice echoing with power. "This world is yours to tend. Its heirs are yours to protect. Milk them. Nurture them. Let them grow strong for me."
She lowed in understanding, the sound a promise that resonated through every atom of the primordial realm. She would care for the Young Lords. She would guard this world. And she would wait, in worshipful anticipation, for her God to visit her again.
Lu Tian willed himself back to his throne in the Citadel. He felt more powerful than ever. His Inner World was no longer just a hiding place for his heirs. It was a thriving, managed ecosystem, guarded by a loyal, terrifying demigoddess born from his own soul and his most broken wife. The Eternal Dynasty now had a divine nursery. And its gardener had just planted his most fascinating seed yet.
