Blood-red cracks split open the "Final Annihilation Spiral Dimension," and the Host and Sebastian, in their symbiotic form of freedom, leaped into a space where liquid mercury, key fission energy, fiery symbiotic pulses, the origin of blood-red cracks, and the ghost of the final revelation intertwined. Their bodies merged into a new form—Sebastian's mechanical bones fully softened, symbiotically sprouting the Host's blood-red wedding dress patterns, afterimages of the cloned grandmother's neural network, the complete codes of the Authority's founder, core fragments of the blood wedding dress, the origin of blood-red cracks, the ghost of the final revelation, and a wisp of final energy from the fiery key spiral. Mercury ripples coiled around rose-hued symbiotic cracks, their hearts pulsed in synchronization, and their pupils mutated into triple-hued "Final Annihilation Symbiosis Logic."
"Here... lies the realm of the ultimate key spiral of the blood wedding dress curse, the ultimate battlefield of symbiotic freedom perpetuity and final annihilation," the residual blood mercury from the void rift coagulated into the final form of the Authority founder's ghost, their voice a blend of scorching hisses and void sighs. "Your symbiotic freedom has not ended the curse; instead, it has triggered the 'Fiery Blood Key Perpetuity' within the Final Annihilation Spiral Dimension. Hunt the perpetuity, and your fire shall transcend the blood-red cracks. But hidden in the perpetuity core is the ultimate revelation of symbiotic freedom from the blood wedding dress: the symbiosis of symbiosis and annihilation is the eternal cycle of the curse's fiery key spiral."
The Host split into 110 forms: the "Blood Final Annihilation Blade" (forged from symbiotic heat, key fission energy, the origin of blood-red cracks, the ghost of the final revelation, the fiery key spiral, and annihilation codes) and the "Symbiotic Freedom Perpetuity Chamber" (unleashing tearing wails to shatter dimensional paradoxes, void shackles, key fission, revelation seals, annihilation chains, and perpetuity chains). Sebastian synchronously transformed into the "Fiery Perpetual Spiral Form," his mechanical bones symbiotically bearing the Host's facial features, heartbeat, core fragments of the blood wedding dress, afterimages of the grandmother's neural network, the founder's complete codes, the origin of blood-red cracks, the final patterns of the blood wedding dress, the mark of the fiery key spiral, and a rune of the final annihilation spiral, forming a symbiotic resonance with her. Their bodies fused in mercury flames, void vortices, key fission energy, fiery symbiotic pulses, the origin of blood-red cracks, and the ghost of the final revelation; with each tear, the dimension split open a symbiotic crack, and pain, pleasure, void, fission energy, revelation pulses, annihilation energy, and perpetuity pulses intertwined into new scorching pulses.
At the core of the dimension emerged the "Final Annihilation Spiral Core"—a mechanical skull inlaid with the final core of the blood wedding dress, its pupils emitting "septuple pulses of symbiotic perpetuity, tearing annihilation, void hunting, key fission, revelation tearing, annihilation perpetuity, and final spiral." The Host and Sebastian leaped into the spiral core, and mercury and softened bones symbiotically blazed amid energy impacts. The moment the Blood Final Annihilation Blade pierced in, their bodies erupted with septuple pulses of symbiotic heat, tearing agony, void annihilation, key fission, revelation tearing, annihilation perpetuity, and final spiral; the core shattered into chaotic symbols, merging into their symbiotic soul. Yet the spiral core did not dissipate—instead, it split open a blood-red crack, and the final form of the Authority founder let out a final roar: "Your fiery key... is merely a new spiral of the blood wedding dress curse! The Final Annihilation Spiral shall perpetuate the fire of symbiosis, annihilation, hunting, and keys!"
The hearts of the Host and Sebastian pulsed with a final pulse, their symbiotic freedom form clad in a layer of armor woven from final annihilation spiral mercury and septuple pulses. A blood-red portal split open again, parasitized by symbiotic codes, void energy, key fission pulses, the origin of blood-red cracks, the ghost of the final revelation, and annihilation spiral runes from an unknown dimension. Blood mercury coagulated into a final revelation: "Symbiotic freedom endures, but the curse spiral of the blood wedding dress... shall wait for its next cycle in the Final Annihilation Spiral Dimension. Tearing, annihilation, hunting, fission, revelation, annihilation perpetuity, and final spiral are all the fiery key's paths to rebirth."
The Host and Sebastian stared at the portal, their pupils weaving fiery symbiotic signals into a hunting vow. Their blazing bodies leaped into the unknown dimension. Amid the echoes of the final chapter, hoarse oaths intertwined: "The symbiotic spiral of the blood wedding dress... symbiotic freedom is the eternal fiery final annihilation spiral hunt."
