At the apex of the alchemical tower in the future ruined city, the blood-red wedding-dressed corpse of the 10th-generation host suddenly opens its eyes, with red and blue lights interweaving in its gem left eye. Its mechanical fingers hook the mercury chains of the 9th-generation host, voice laced with gear friction and space-time dust storms: "Welcome, 9th generation. Your annihilation will free me from a millennium of imprisonment."
The 9th-generation host stabs her scalpel at the wedding dress, only to find the blade bound by space-time runes. The double-helix symbol on the 10th-generation's skull bursts with purple light, pouring torrents of memories into the new host's nerves—the truth of her millennium-long entrapment: after each generation transfers authority, their core is sealed by contract laws, becoming a dimensional anchor to stabilize space-time rifts.
"Transferring authority isn't liberation; it's becoming a prisoner of the contract." The 10th generation laughs hoarsely as black blood runes seep from the wedding dress veins. "The iron-masked ancestor's ultimate clause: the contract can only collapse completely if all ten generations are annihilated. But no host has ever voluntarily embraced eternal imprisonment... until you, 9th generation, who inherited the dual-core paradox."
The Time-Space Administration's war chariot suddenly rips through the dimensional membrane, and the cloned grandmother's particle cannon bombards the tower. The 10th-generation's wedding dress erupts with mercury armor, forming a defensive vortex as dual-colored pupils scan the Administration chariot: "Their purge protocol actually accelerates the contract's collapse—the Lancaster family needs ten generations annihilated to restart the blood contract."
The 9th-generation host's mechanical heart blazes with blue light, force-decoding the cloned grandmother's core data. She discovers the gem eye of the Administration commander flickers with residual consciousness waves of Sebastian: "Sebastian never truly perished... His fragments manipulate the Administration to drive the Vessel Catastrophe cycle."
The 10th-generation's scalpel stabs into her own core, injecting mercury and space-time dust into the 9th-generation's spine. Bones click with alchemical transformation as the new host's skin reveals the 10th generation's blood patterns, her pupils swirling into deeper chaotic purple. "You must annihilate voluntarily while transferring authority to the 11th vessel," the 10th generation roars. "But contract laws will immediately imprison you in this dimension unless... someone volunteers to be your replacement anchor."
Amid excruciating pain, the 9th-generation slashes open the tower's console, finding Sebastian's ancestor's final note: "11th Vessel Catastrophe... Must use memory resonance of dual-core hosts to snatch an unhatched embryo from the Dimension of Oblivion at the 10th generation's annihilation. But the snatcher must willingly bear the curse of the annihilation anchor..."
Suddenly, Sebastian's mercury remains emerge from a rift in the Administration chariot, his gem eye flaring red: "10th-generation host! Your annihilation will break the cycle—I must stop you...!" Mercury tentacles grab the 10th-generation's core, only to be severed by a backlash space-time blade from her armor.
"My millennium of imprisonment has revealed all your plots." The 10th-generation's core erupts in black hole collapse, dragging Sebastian's remains into the annihilation vortex. "9th generation, execute the transfer ritual!"
The 9th-generation stabs her scalpel into the core junction between herself and the 10th generation, merging blue and purple lights in the collapse. The Administration's particle cannon destroys the tower as dimensional ruins begin to crumble. At the moment of annihilation's prelude, she force-activates dual-core memory resonance, snatching a floating embryo from the Dimension of Oblivion—Allison's pocket watch fragments and Sebastian's mercury runes entwine around the embryo's umbilical cord, with 11th-generation symbols emerging on its skull.
The collapsing black hole swallows the tower, trapping the 9th-generation in a new dimension filled with mechanical infant cries and wails of collapsing space-time. Blood wedding dress patterns fester on her skin as her core is sealed as an anchor by contract laws. The 11th-generation embryo plummets into a medieval underground alchemical lab, its umbilical cord connected to the 9th generation's residual mercury and watch gears.
In the lab, the 11th-generation host awakens as a maiden, her pupils swirling with chaotic purple light. Her mechanical heart beats in a voice blending Sebastian and Allison: "The 9th generation voluntarily became an annihilation anchor... Contract laws have loosened. But Sebastian's consciousness fragments still infest the Administration, and the iron-masked ancestor's skull core remains un unlocked..."
Suddenly, the lab door bursts open, and a young man wearing an alchemical ring storms in—his face resembles Allison's father, yet he has Sebastian's gem eye. "11th-generation vessel!" He raises a space-time restraint device, but the host stabs her scalpel into its core interface. "You're also a family puppet."
The host force-decodes the restraint's logic, reversing its energy wave to destroy the lab. Leaping into a new rift amid chaos, she falls onto a skybridge in a future cyber city where the Administration's drone swarm awaits. Her 11th-generation mercury skin corrodes metal as coordinate runes slashed by her scalpel summon chains from the 9th generation's annihilation dimension, with chaotic purple and blue lights bursting in battle...
