The battlefield quaked under the fury of two opposing forces—light and abyss, divine and eldritch. The golden dragons surged forward, their colossal forms cutting through the darkness with radiant ferocity. Each movement they made left trails of incandescent energy, scorching through the void-born creatures Robin had summoned. The abyss howled in response, its spawn twisting and morphing into new, hideous forms, some slithering like serpents of pure shadow, others towering with grotesque, spiked limbs, lashing out at their celestial adversaries.
Robin's grin widened, her body flickering in and out of stability as she hovered above the carnage, her eyes alight with something between madness and exhilaration. She swept her scythe outward, the fabric of reality itself splitting apart in a jagged arc, a gateway into oblivion yawning open before her. From its depths, spires of blackened bone and eldritch tendrils surged forth, piercing through the air like spears aimed at Zhongli.
He did not flinch. With a measured breath, he extended both arms, his fingers curling into the air. The golden radiance beneath him pulsed, and the sand trembled as it transformed. Monolithic walls of stone erupted, ancient carvings of celestial sigils blazing across their surface. The abyssal projectiles struck them but did not shatter; instead, the stone absorbed the impact, rippling like liquid gold before hardening once more.
Robin's expression flickered with something like respect. "Not bad...But let's see how well you handle this Zhongli!"
With a beat of her wing, she vanished, reappearing directly above him, her scythe already descending in a vicious arc. Zhongli met the strike with his arm, a golden shield materializing in a split-second to intercept the abyssal blade. The clash sent shockwaves outward, cracks forming in the air itself as raw energy erupted from the impact. Robin twisted, using the recoil to propel herself into a whirlwind of slashes, each one faster than the last, her blade seeking any weakness in his defense.
Zhongli did not yield. His movements were precise, deliberate, every block and parry a calculated response. His golden barriers shimmered and shifted, reshaping themselves with every impact, forming layers upon layers of unbreakable defense. Yet Robin was relentless. She danced between shadows, her form shifting unpredictably, forcing him to remain on constant guard.
Then she changed tactics.
With a sudden shift, she abandoned the direct assault and instead lashed out with her abyssal energy. The darkness surged forward in a great tidal wave, crashing against Zhongli's defenses like an ocean of consuming night. The golden earth beneath them buckled under the weight of the encroaching void, struggling to maintain its divine integrity. Zhongli narrowed his eyes.
Zhongli raised a single hand to the sky....
The world answered that call..
From deep within the deserts...titanic chains of molten gold burst forth, each link engraved with ancient seals of power. They shot toward Robin like celestial vipers, weaving through the air with terrifying speed. She barely managed to dodge the first wave, but more came, shifting unpredictably, seeking her out with unerring precision. One wrapped around her arm, another her leg, dragging her downward as their divine energy burned against her abyssal form.
Robin hissed in frustration, shadows writhing around her in an attempt to break free. The chains tightened. Zhongli clenched his fist, and the heavens rumbled. The chains began pulling her downward, toward a massive glyph that had silently formed on the battlefield—an intricate sigil of golden energy, pulsing with power ancient beyond measure.
Robin's eyes widened. "Oh, hell no."
Summoning all her strength, she unleashed an explosion of abyssal energy, shattering the chains that bound her. The resulting detonation sent her flying back, but she recovered midair, her scythe spinning in her grip. She landed atop a spire of blackened stone she had conjured, glaring down at Zhongli with renewed fervor.
"Alright, old man," she panted, her grin returning despite the strain evident in her stance. "You got me good with that one. But I'm done playing."
The abyss pulsed violently around her. The air twisted, and the very concept of space seemed to fracture. A deep, guttural sound reverberated through the battlefield as the darkness behind Robin began to shift—no longer mere tendrils, no longer formless shadows. Something vast and terrible stirred within the abyss, something ancient and beyond mortal comprehension.
Zhongli's expression did not change, but his stance shifted ever so slightly, a silent acknowledgment of the escalation. He reached behind him, and in a single motion, summoned his polearm—a weapon of exquisite craftsmanship, its golden surface inscribed with the weight of forgotten millennia. The air grew heavier, the battlefield frozen in a moment of tense anticipation.
Robin's grin turned razor-sharp. "Let's see how you handle a real god's wrath."
She raised her scythe high, and the abyss answered. From its depths, an enormous clawed hand emerged, black as void, seething with abyssal corruption. It tore through the battlefield, reaching toward Zhongli like a harbinger of annihilation.
Zhongli took a slow breath, and then, with the weight of eons in his voice, he spoke.
"Tianheng—awaken."
The desert responded. The ground trembled as ancient mountain roots, long buried beneath the sands, erupted into the battlefield. Towering formations of divine rock surged skyward, each one glowing with celestial power. A deep, resonant hum filled the air as the golden dragons coiled around the landscape, their forms merging with the rising mountains, their energy intensifying.
Zhongli took a single step forward, and the heavens trembled.
Robin let out a sharp laugh, twisting midair as abyssal wings expanded from her back, tendrils of corruption intertwining with their leathery form. She dove, scythe spinning, her form vanishing and reappearing in an unpredictable flurry of motion. Each strike she aimed at Zhongli was met with divine precision, his spear intercepting her attacks with unshakable resolve.
With a flick of his wrist, he sent forth a golden shockwave, forcing Robin to twist away. But she wasn't done. Darkness churned behind her, and from its depths, spectral figures emerged—twisted echoes of forgotten gods, their hollow eyes locked onto Zhongli. They lunged, clawing at the very essence of reality, attempting to tear apart his divine form.
Zhongli's gaze remained firm. He raised his polearm, and the land answered once more. The mountains trembled as ethereal figures of long-departed warriors formed from golden light, clashing with the abyssal specters in a battle of lost divinity.
Robin landed on a floating shard of blackened stone, eyes gleaming with challenge. "Well, this just got interesting. Let's see how much further we can push this."
Zhongli exhaled slowly, lowering his spear into a ready stance. "Indeed. Let us test the limits of eternity."
And so, the battle raged on, the heavens and abyss locked in a struggle beyond time itself.
