The ruby fire of the blade screamed its descent, a searing streak aimed directly at Zong Xiaotian’s bare breast. He felt the intense heat before the metal even touched, the air crackling, his skin tightening, the smell of ozone filling his nostrils. His arms lay inert, flat against the damp cavern floor, a stark display of absolute surrender. Zong Hentian sneered in cruel triumph, expecting the geyser of blood, the choked cry of his disgraced son.
Then, the sword struck.
Not with the wet, fleshy thud Hentian anticipated, but with a sharp, grinding screech, a sound of rock on metal that reverberated through the tight grotto. Sparks, not blood, erupted in a blinding shower, illuminating the surprised fury on Hentian’s face. His blade, instead of piercing flesh, had embedded itself halfway into a strangely resilient, fist-sized rock that had materialized precisely where Xiaotian's heart should have been. The stone pulsed with a faint, earthy glow, cracks spiderwebbing across its mineral crust from the impact.
Baozi, the judgmental spirit turtle no larger than Xiaotian's palm, perched on his shoulder, glaring with beady contempt at Zong Hentian. It let out a tiny, indignant burp, a puff of faint grey dust escaping its nostrils, before waddling with surprising speed to Muxi’s side, nudging her gently with its head.
Zong Hentian stared, mouth agape, the crimson glow of the ignited edge reflecting in his disbelieving pupils. He had put all his power, all his murderous intent, into that single strike, only for it to be foiled by… a pet rock?
“My, my, father,” Xiaotian said, a slow, predatory grin spreading across his blood-smeared lips. He coughed, a small amount of blood dribbling from the corner of his mouth, a stark contrast to the defiant glint in his eyes. “Did you really think I’d just roll over and play dead? Even a crippled dog has a few tricks up its sleeve. Especially when his best friend is a master of elemental manipulation and has a peculiar taste for high-grade spiritual ore.”
Yao Qingyu’s melodic, teasing laughter rippled through the air, seeming to emanate from the very stone around them. “Oh, my little rogue. So you did listen. Baozi truly is a rare treasure. Not just a pet, is he? A heart of stone, indeed.”
Before Zong Hentian could process the deception, before he could retract his sword, Xiaotian's left hand shot out. His fingers, still stained with his own blood, wrapped around Hentian’s wrist, gripping with a surprising, bone-jarring strength. The elder man, overextended and off-balance from the unexpected resistance, found himself unable to pull back.
“You foolish boy!” Hentian roared, his face twisting into a mask of pure hatred. He tried to twist away, to bring his free hand to bear, but Xiaotian held firm.
“Foolish?” Xiaotian’s voice dropped, losing its usual cheeky lilt, replaced by a raw, guttural growl that chilled the stagnant air. “You stole my blood. You crippled me. You murdered my mother. And now… now you’ve given me the perfect opening to take back what’s mine.”
A surge of furious, desperate force erupted from Xiaotian’s core. It wasn't the gentle flow of cultivation, but a violent, magnetic force. The weapon, still embedded in the illusionary rock, began to hum, not with Hentian’s power, but with a new, resonant frequency. Threads of ruby light, fine as spider silk, began to peel away from Hentian’s body, from his stolen lineage, and stream towards Xiaotian’s outstretched hand, drawn by an ancient claim.
“The Blood-Debt Reversal!” Yao Qingyu’s voice was a delighted, dark whisper. “Feel it, little phoenix! Reclaim your legacy!”
Zong Hentian shrieked, a sound of pure agony and terror. He felt it, the profound violation, the tearing, the draining. It was as if his very essence, the lifeblood that pulsed through his veins, was being violently siphoned away. His face blanched, his once vibrant features now sunken and grey. The crimson blaze, which had been the source of his tyrannical power, was turning against him, a river flowing upstream, back to its original spring.
The subterranean chamber trembled. Loose rocks rained down from the ceiling. The air grew thick with suffocating pressure, a maelstrom of conflicting spiritual currents. Xiaotian gritted his teeth, his entire being focused on the ferocious pull. He wasn’t just taking back his birthright; he was ripping it from the very fabric of Zong Hentian’s existence. Half of the stolen legacy, a burning torrent of crimson fire, surged back into Xiaotian’s chest, into his core, reawakening dormant power that had been suppressed for years.
With a final, desperate roar, Zong Hentian wrenched his arm free, but it was too late. The damage was done. He staggered back, half his power gone, his cultivation base severely destabilized, looking like a wizened, ancient man. His eyes, now dull and terrified, met Xiaotian’s.
“This… this isn’t over!” he croaked, but his voice lacked any true menace.
Xiaotian merely smirked. “Oh, father. It’s barely begun.”
The rock floor buckled. The massive, pulsating ‘Spirit Vein’ — Yao Qingyu’s true demonic core — shuddered violently, destabilized by the chaotic resonance. Cracks spiderwebbed across its surface, glowing with an ominous, internal light. A deafening groan ripped through the stone, and the entire structure began to collapse inward.
“The core can’t take it!” Yao Qingyu cried, her voice strained. “We have to go! Now!”
Without hesitation, Xiaotian moved. He scooped Lin Muxi into his arms, ignoring her startled gasp. She felt impossibly light, frail. Baozi, clutching a small, glowing chunk of slag, scrambled onto his shoulder. The air around Xiaotian shimmered, now imbued with a renewed, searing power.
He didn't look back as tons of stone and earth crashed down, burying Zong Hentian in a tomb of his own making. Xiaotian unleashed a concentrated blast of his reawakened blaze, a crimson spear of power that tore through the collapsing ceiling, vaporizing rock and soil, creating a vertical tunnel to open sky.
His cultivation base surged, rushing back to its peak, then past it, fueled by the returning bloodline. The familiar rush of boundless vigor filled him, a sensation he had not known since his fall. He ascended, a phoenix reborn from the ashes, Muxi held close against his chest, Baozi clinging on for dear life. The air grew cooler, fresher, as they blasted through the final layer of earth.
They breached the mountain crust, emerging onto the high, windswept peaks overlooking the Azure Ascendant Sect. The sun, which had been setting, cast long, weary shadows across the distant courtyards. But the light was wrong. As Xiaotian’s reclaimed birthright pulsed within him, intertwining with Yao Qingyu’s nascent demonic aura, the entire sky above the Azure Ascendant Sect turned a terrifying, apocalyptic red.
