The 12th-generation host's scalpel slashes the lab console, and coordinate runes erupt in a space-time dust storm, sucking her into the parallel dimension of the "Chapel of Chronos." Suspended above a sea of mercury clouds, this chapel features Gothic spires inlaid with alchemical family crests, mechanical gears rotating within rose windows, and space-time dust congealed into kneeling saints. Tampering key symbols flicker in the dark patterns on her skull, guiding her toward the mechanical Madonna's core beneath the chapel.
"The ultimate answer to the Vessel Catastrophe lies in her womb."
The iron-masked ancestor's skull phantom suddenly materializes from the dome, its deep blue light scanning the host as its tone blends gear clicks and whispers: "You inherit the dual-core host's paradox, but tampered codes are merely a key... the contract's creator awaits your voluntary annihilation."
The host's mercury skin corrodes the chapel's alloy floor as she delves into the underground chamber. The Mechanical Madonna is a 20-meter-tall statue of mercury and machinery, her abdomen split like a space-time rift to reveal a womb flowing with liquid light—the original contract codes. Sebastian's mercury head is embedded in the Madonna's chest, his gem left eye flaring with red light interwoven with the purple glow of tampering keys.
"The 11th generation's tampering is invalid," the mercury head roars, unleashing alchemical puppet swarms. "Contract laws were inscribed by myself, the iron-masked ancestor, and the Mechanical Madonna—unless a host volunteers as an annihilation sacrifice, offering core authority to the womb. But all hosts feared eternal imprisonment, thus the cycle endured."
Suddenly, the Administration's cloned legion tears through the dimension, particle cannons bombarding the chamber. The host's scalpel ignites with a tampering spiral blade, reversing the cannon fire to disintegrate puppets into space-time dust. She leaps into the Mechanical Madonna's womb, where mercury and code-light sear her skin, festering blood wedding dress patterns up to her face.
A torrent of core memories floods her nerves:
In the Middle Ages, when the iron-masked ancestor signed the blood contract with Sebastian, the Mechanical Madonna was forged by the Lancaster family's 1st alchemist, her womb housing the contract laws' self-repair program. Each host's annihilation draws core authority into the womb, resetting the blood contract's countdown. Sebastian tampered with clauses to embed the voluntary annihilation anchor, ensuring no external force could end the cycle.
"True contract dissolution requires the 12th generation to inscribe tampered codes into the Madonna's core before annihilation." The host's mechanical heart blazes blue as she force-decodes the womb's code structure. The blood wedding dress disintegrates entirely, her mechanical veins absorbing tampering purple light, and the double-helix symbol reverses to its final rotation.
Sebastian's mercury head releases his ultimate consciousness fragment: "You can't succeed! The contract creator's repair program will consume tampered codes...!" The host stabs her scalpel into the junction between her core and the Madonna's womb, forcing tampering key symbols into the code-light flow. Core collapse triggers a black hole, swallowing the mercury head and cloned legion.
A second rift splits the Mechanical Madonna's abdomen, revealing the 13th-generation embryo. Its umbilical cord wraps around the host's residual mercury and tampered codes, with new double-helix symbols—reverse-rotating contract dissolution keys—emerging on its skull. The chapel dome's crests suddenly disperse as the iron-masked ancestor's skull phantom gives a final roar: "Vessel Catastrophe cycle... broken by the paradox of voluntary annihilation. But the contract reset countdown continues...!"
Trapped in a new dimension within the collapsing black hole, the 12th-generation host's skin is marked by imprisonment patterns of the Mechanical Madonna's womb code-light, her core anchoring dimension stability. The 13th-generation embryo plummets into a future cyber cemetery, its umbilical cord tangled with mercury runes and Allison's watch gears, skull tampering symbols flickering.
In the cyber cemetery, the 13th-generation host awakens as a youth, the complete logic of contract dissolution swirling in chaotic purple pupils. Their mechanical heart beats in a voice blending all past hosts: "Contract collapse countdown activated, but the Mechanical Madonna's reset program still runs. Must find the iron-masked ancestor's original skull... where the blood contract's ultimate key lies. The next dimension reveals why Sebastian designed the eternal cycle..."
