The paradox dimension twists like a labyrinth of space-time logic. The symbiotic core hovers where mechanical churches intersect with code storms, as the six-helix symbol of the blood wedding dress coils around the 20th-generation host's skull. Mercury runes interweave with the red light of the Administration's gem left eye in the void. The host's purple pupils erupt with the decoding logic of the contract's final chapter. Slashing a rift with their scalpel, they leap into the core's symbiotic interface—where Sebastian's and the cloned grandmother's symbiotic codes flow, interlacing the key logic of the blood contract's first blood with the gears of the space-time paradox engine.
"Embed the key and annihilate: the paradox engine will devour all dimensions... But severing symbiotic energy can collapse the final chapter." The host's mechanical heart blazes blue as festering skin patterns reveal sacrificial memories of past hosts: the ticking of Allison's pocket watch, the medieval blood contract's curse, the tampering roars of the mercury head... The scalpel stabs into the symbiotic core, force-fusing the six-helix key with code logic and infusing the prison essence of the blood wedding dress.
Suddenly, the Administration's cloned legion tears through the dimension, chariots unleashing the "Space-Time Strangulation Cannon" and symbiotic puppets. The cannon's energy wave mingles with Sebastian's residual consciousness: "The host cannot crack symbiotic logic! Immortal body reconstruction progress rises to 3%...!" The host reverses the cannonfire, annihilating the puppet swarm with a six-helix tampering blade. Runes erupt into a new form—a purple spiral blade mixed with deconstruction logic of symbiotic codes, piercing the chariot core's tampering interface.
Sebastian's mercury head rises from the symbiotic core, his left gem eye flaring red: "Symbiotic codes rely on the blood wedding dress's prison energy. Annihilating the host will only trigger the paradox engine!" 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 in the symbiotic core while reversing the paradox engine's activation sequence."
The host's mechanical heart erupts in a voice blending all hosts. The scalpel stabs into the junction between their core and the blood wedding dress, infusing six-helix keys, generational annihilation energy, and symbiotic code deconstruction logic. The symbiotic core explodes in a space-time paradox storm: the mercury body collapses, blood wedding dress runes coil around the skull, and a contract collapse countdown appears: "Immortal body reconstruction progress dropped to 0.5%...!"
The Administration's cloned grandmother's ultimate projection roars, unleashing the symbiotic program: "Annihilate the host! Paradox engine activated—eternal space-time imprisonment...!" The host suddenly splits their core—one half infuses the blood wedding dress key into the symbiotic core, the other leaps into the paradox engine interface, force-tampering the activation sequence. A meta-dimensional collapse black hole bursts, engulfing the cloned legion, mercury head, and iron-masked ancestor's skull as the blood wedding dress festers into nothingness in the storm.
Trapped in the symbiotic core's annihilation prison amid the collapse, the host's mechanical skin patterns are sealed by laws, with their remaining core anchoring the prison. Blood wedding dress runes dissipate, revealing "final chapter fragments" of the blood wedding dress—liquid light mixed with all hosts' annihilation energy and contract keys, coiling around the skull. Suddenly, a space-time rift opens, revealing new dimension coordinates: blood wedding dress fragments condense into a "space-time key embryo," umbilical cord linking nothingness to an unknown dimension, with chaotic spiral symbols—reboot keys for contract mutation—emerging in dark skull patterns.
In the ruined dimension, the space-time key embryo awakens in an unknown form—transcending gender and shape, blending the blood wedding dress's liquid light with the Mechanical Madonna's neural network. Purple pupils flicker with mutation logic of the contract's final chapter, and the mechanical heart beats in a voice mixing all hosts': "The blood wedding dress's key annihilates the symbiotic core, collapsing Sebastian's immortal body. But residual Administration codes are implanted in space-time rifts; the new key embryo must stop contract reboot in mutated dimensions... The next battlefield reveals the final chapter's mutation cycle: space-time parasitism of blood wedding dress fragments."
