The quantum acupuncture needles glowed like trapped supernovae under Lin's electron microscope. Each 0.3mm-wide zhen contained fullerene cages housing quantum dots, their spin states precisely mirroring constellations in the Dunhuang Star Chart carved into Jingyuan Villa's marble floor.
"These aren't medical tools." Lin's breath fogged the microscope lens. "They're neural network projectors."
Ethan's reflection wavered in the obsidian observation window. Moonlight carved his profile into something resembling the villa's deco-era gargoyles. "My mother's research team implanted twelve of these in my prefrontal cortex when I was six. For enhanced celestial navigation capabilities."
The microscope image blurred as Lin's tremor returned - the same subtle shaking that had begun three days after the vault radiation exposure. She counted seven nanoscale serial numbers on the golden needle before realizing they matched the Seven Mansions of the Azure Dragon.
A child's laughter echoed through the villa's abandoned west wing.
"Show yourself!" Ethan's quantum watch projected a holographic sword from Three Kingdoms-era bronze algorithms.
A girl emerged from the shadows clutching a Tesla coil-modified R2-D2 doll. Her left iris shimmered with the same quantum dot pattern as the acupuncture needles. "Brother promised me real stars."
Lin's Geiger counter chirped. "Her radiation levels—"
"Meet my sister Nina." Ethan's voice turned to liquid helium. "Or what's left after Father's quantum eugenics trials."
The nine-year-old tilted her head, servo motors whirring beneath paper-thin skin. "The Leonids are 32 days late. Brother lied about making meteor showers."
Lin's tablet pinged with a WeChat notification from Shanghai Children's Hospital. Five pediatric oncology patients had just flatlined. Her fingers tightened around the jade bi disc still warm from the vault. "You used my dark matter models to create artificial meteor showers for dying children."
Ethan's silence was admission enough.
Nina's doll sparked. "The leukemia ward's rooftop observation deck cost 4.2 million RMB. Father said Brother's fireworks needed test audiences."
The villa's antique German-made elevator suddenly descended with a cable-snap scream. Ethan shoved Lin behind a Tang Dynasty astrolabe as tungsten alloy darts embedded where her carotid had been.
"Security AI's awake!" He smashed a Ming vase to reveal a biometric scanner. "The meteor control room's behind the star chart!"
Lin followed through shifting holograms of Song Dynasty astronomical clocks, her Louboutins crushing fallen quantum chips. Nina's laughter pursued them like dark matter particles, the child's footsteps alternating between flesh and mechanical precision.
The control room smelled of ozone and childhood trauma. Eighteen 8K screens showed real-time orbital trajectories above Shanghai, interspersed with encephalograms of children watching Ethan's counterfeit meteor showers. A brain-computer interface headset dripped with electrolyte gel on the central console.
"Every fake meteor was a memory wipe." Ethan activated quantum encryption protocols. "Father's associates paid premium to forget what they saw in the leukemia ward."
Lin's fingers flew across the star chart touchscreen. "These encephalograms show hippocampal suppression. You're not just erasing memories—"
"You're implanting false ones." Nina materialized on a ceiling projection screen, her form pixelating into a 1930s Shanghai opera singer. "Brother makes them see angels instead of chemotherapy ports."
Radiation alarms howled as the villa's defenses activated. Ethan grabbed Lin's waist, their bodies flush against a bronze armillary sphere vibrating with incoming drone strikes. "The control system's linked to my occipital implant. If we—"
She jammed the BCI headset onto his skull. "Show me the truth."
Neural feedback flung them into shared memory space.
Lin gasped. Twelve-year-old Ethan crouched under a hospital bed, watching his mother's quantum needles pierce Nina's thalamus. The girl's screams synchronized with the real-time encephalograms flashing across the vaulted ceiling. Outside the bulletproof glass, LED drones painted counterfeit Perseids across Shanghai's smog-choked sky.
"Why?" Lin whispered through the memory haze.
The child Ethan looked up with neutron-star eyes. "Because real stars are too cruel to comfort dying children."
Reality snapped back as a drone crashed through the stained glass celestial map. Nina's biomechanical arm emerged from the wreckage, graphene tendons sparking. "Father says playtime's over."
Ethan's nose bled onto the console. "The IBM 5100's in the garden! It can override—"
"Go." Lin shoved him toward the secret passage. "I'll hold her off with the armillary sphere's electromagnetic pulse."
"Don't touch the mercury!"
Too late. Her palms connected with the ancient instrument's liquid metal channels. Five thousand years of astronomical knowledge flooded her synapses - Shang Dynasty eclipse records merging with dark matter algorithms in a cosmological Big Bang.
The villa's defensive systems short-circuited in cascading failures. Nina's biomechanical joints seized mid-attack, her quantum eye dimming to obsidian. Lin's vision tripled as neurotoxins from the mercury interface attacked her blood-brain barrier.
Ethan caught her as she collapsed. "You imbecile! The sphere's quicksilver contains—"
"Temporal lobe epilepsy triggers." She grinned through seizure aura. "Your sister's neural patterns... match the children's encephalograms..."
The IBM 5100 spat out a ticker tape message as he carried her through chrysanthemum fields:
GOLDEN NEEDLES = QUANTUM TUNNELING PROBES
TARGET: LANGQIAO PEDIATRIC HOSPITAL
Police helicopters circled overhead. Ethan's Tesla swerved into the villa's courtyard, its bulletproof panels pockmarked from their last escape. He strapped Lin into the passenger seat, fingers lingering on her carotid pulse.
"Why does your sister have a 1950s opera singer's digital ghost?" Lin slurred, neurotoxins blurring the line between memory and reality.
"Because Mother's consciousness is still trapped in the..." His words dissolved into static as her seizure climaxed.
In the lightning storm of her misfiring neurons, Lin saw it - Ethan's childhood blueprint for artificial meteors, scribbled in crayon over Einstein's field equations. The sticky fingerprints at the margins contained his DNA, his tears, his shattered belief in celestial mercy.
When consciousness returned, they were parked beneath Sheshan Observatory's radio telescope array. Ethan pressed an ice-camped cloth to her forehead. "The neurotoxin's half-life is twelve hours. You'll hallucinate dead relatives."
"Already am." She nodded at the rearview mirror. Her mother's ghost sat cross-legged in the backseat, knitting dark matter into a traditional Chinese longevity lock.
Ethan's quantum watch lit up with a priority alert. Onscreen, Nina's biomechanical body floated in a sensory deprivation tank beneath Huangpu River, her remaining organic eye tracking their coordinates through Shanghai's surveillance grid.
"Father activated phase two." He showed Lin a live feed of Langqiao Hospital's rooftop. Three hundred children in radiation gowns tilted their faces skyward as LED drones prepared another artificial meteor shower. "The next show implants permanent cognitive obedience patterns."
Lin's smartphone buzzed. Five minutes earlier, her dead mother's WeChat account had sent MRI scans of a glioblastoma blossoming in her parietal lobe - and a single ancient star map coordinate.
Nina's synthesized voice issued from the car speakers: "Brother must choose. The physicist's life, or the children's free will?"
Ethan's palm covered the manual driving mode override. The Tesla's quantum core began recalculating routes to fourteen possible endpoints, each representing a different moral catastrophe.
Lin grabbed the golden needle from his pocket. "There's a third option."
She plunged it into his jugular notch.
The Tesla's AI screamed as Ethan's occipital implant data flooded its navigation system. Lin's vision dissolved into shared memory space - a nine-year-old boy coding fake constellations into hospital VR headsets, each digital meteor containing fragments of his stolen childhood.
The car accelerated toward the Huangpu River tunnel.
