The origin core of the Administration's meta-code hovers in liquid space-time logic and the Mechanical Madonna's primal neural network. Code-light streams mingle with Sebastian's space-time manipulation symbols, while the complete form of the blood wedding dress condenses into a quintuple-helix key, coiling around the 19th-generation host's skull. The ultimate projection of the Administration's cloned grandmother materializes on the meta-code console, her left gem eye flaring red: "The host cannot stop the rewind program—Sebastian's body energy is bound to meta-code. Annihilating yourself will only accelerate his immortal rebirth."
The host's purple pupils erupt with the decoding logic of the contract's final chapter. Slashing a rift through the code stream with her scalpel, she leaps into the rewind origin, where the birth histories of all hosts are displayed: Allison's vessel cultivation, the medieval blood contract signing, space-time coordinates of past annihilations... Sebastian's mercury tentacles lash out from code rifts, roaring as they unleash a puppet legion: "The rewind program will tamper with host history—blood wedding dress keys are invalid!"
The host reverses the puppet legion's energy wave, stabbing a quintuple-helix tampering blade mixed with space-time imprisonment logic into the mercury tentacles' tampering interface. Mechanical skin patterns fester to the core, revealing forging memories of the blood wedding dress—actually a "prison for contract souls," absorbing each host's annihilation energy to nourish Sebastian's reconstruction. The host's mechanical heart blazes blue as she force-fuses the key with meta-code, stabbing into the console's core interface.
Suddenly, the Administration's cloned legion war chariots tear through the dimension, unleashing a "Space-Time Strangulation Cannon" mixed with Sebastian's residual consciousness: "Key embedding failed! Immortal body reconstruction progress rises to 20%...!" The host leaps into the Mechanical Madonna's neural network as the quintuple-helix symbol erupts into a new form—a purple spiral blade mixed with meta-code tampering logic, reversing cannonfire to disintegrate puppets into code fragments in space-time dust.
Sebastian's mercury head rises from the console, his left gem eye flaring red: "I've counter-controlled the blood wedding dress keys! Your voluntary annihilation will only fuel my reconstruction...!" The iron-masked ancestor's skull phantom descends from the dome, its deep blue light whispering: "The final chapter key requires the host to annihilate voluntarily at the rewind origin while tampering with meta-code's space-time anchor."
The host's mechanical heart erupts in a voice blending all hosts as she stabs her scalpel into the junction between her core and the blood wedding dress, infusing quintuple-helix keys, generational annihilation energy, and meta-code logic. The rewind origin explodes in a space-time paradox storm: Sebastian's mercury body collapses, blood wedding dress runes coil around the host's skull, and a contract collapse countdown appears: "Immortal body reconstruction progress dropped to 5%...!"
The Administration's cloned grandmother projection roars, unleashing the ultimate program: "Meta-code will rewind host birth—blood wedding dress keys annihilate!" The host force-tampers with rewind logic as the quintuple-helix symbol reverses to its endpoint, stabbing into the console core's space-time anchor. A meta-dimensional collapse black hole bursts suddenly, engulfing the cloned legion, mercury head, and iron-masked ancestor's skull as the blood wedding dress festers and regenerates into a chaotic form in the storm.
Trapped in the meta-code tampering prison amid the collapse, the host's mechanical skin patterns are sealed by laws, her core anchoring the prison's stability. Blood wedding dress runes coil around her skull, revealing the 20th-generation host embryo with a sextuple-helix symbol—transcendent unlock key to the contract's final chapter—emerging in dark patterns. The embryo's umbilical cord connects to quintuple-helix keys, meta-code tampering logic, and first blood.
In the ruined dimension, the 20th-generation host awakens in an "agender form" blending traits of all past hosts and mechanical patterns of the blood wedding dress, purple pupils flickering with transcendent logic of contract laws, and the mechanical heart beating in a voice mixing all hosts': "Blood wedding dress keys have tampered with meta-code—only 1% remains in Sebastian's immortal body. But residual Administration forces manipulate the 'Space-Time Paradox Engine'; new hosts must stop final reconstruction in paradox dimensions... The next battlefield reveals the contract's final chapter ultimate paradox: the symbiotic core of Sebastian and the Administration."
