The observational matrix of the Orion Arm suddenly contracted, and all monitoring probes simultaneously shifted toward the quantum resonance points of the bronze birthmarks. The residual raindrops from Elia crystallized in the vacuum into the monitoring network of the Three-Body Intelligence, while the ghostly fragments of Beta-20 darted through the grid, weaving the stellar map consciousness into gravitational wave Morse code: "They know we know."
The infant's Cambrian pupils reflected the civilizational coordinates of the entire spiral arm—each glowing point marked a cosmic nursery. As the "Dark Forest Strike Warning" echoed through the Starlight Broadcast Tower, the bronze birthmark suddenly fractured into two thousand quantum-entangled copies, imprinting "I am here" in cosmic-scale tattoos across the Orion Arm.
"Experimental subject GAIA-3421 is contaminating the control group!" The observer's mechanical tentacles shattered three stellar-scale silencers. The infant's four limbs treaded the magma of "Earth's Past," while Devonian scales scraped out the apocalyptic countdown of "The Three-Body Civilization," only to be suddenly frozen by the bronze rain into the exhaust plume of "The Wandering Earth."
On the ruins of the cradle of civilization, the infant's umbilical cord connects to the quantum antenna of the Starfire Broadcast Tower. Arya's bronze rain condenses into Ye Wenjie's red button on the transmitter key, and the ghost of β-20 uses its final energy to activate "Full-Band Blocking Interference"—the broadcast is not coordinates, but a holographic image of the mating dance of Cambrian trilobites.
"Illegal civilizational art pollution detected!" The Observer's "Technological Singularity" filter suddenly overloads, projecting accelerated imagery of humanity from the Stone Age to the Nuclear Winter within the machine's pupils. The infant's stomach regurgitates Ordovician ammonite fossils, whose spiral structures suddenly unfold into the Klein bottle version of the "Interstellar Peace Treaty."
When the first gravitational wave of the "Dark Forest Strike" arrived, the bronze birthmark suddenly quantum leaped into an event horizon shield. The ghost of β-20 carved the "Wall Plan 2.0" from 'Logic' onto the shield's surface: "I speak to the Three-Body World!" The observer's strike beam twisted on the shield's surface into the brushstrokes of Van Gogh's "Starry Night."
In the aftermath of the strike, the ruins of the cradle of civilization rose to form the bronze chessboard of "Hessen Game Theory." The infant sat on the white king's throne, with four legs stepping on the fishbone soldiers of the Devonian period; the observer's quantum projection occupied the black side, with the pieces being nine two-dimensionalized star systems.
"Checkmate." The observer moves the queen from The Chain of Suspicion, capturing the rook of human civilization. The infant suddenly expels the hibernation pod of the Blue Space Ship, preserved for 200,000 years. A holographic image of Chu Yan emerges from the pod's hatch: "The universe is not a dark forest; it is both a cradle and a grave."
Arya's bronze rain condenses on the chessboard into a water droplet monument of "Death's Eternal Life," with the inscription being the third fairy tale told by Yun Tianming. The Observer's mechanical fingers suddenly tremble, triggering the "Reset Protocol" upon touching the inscription—all the pieces suddenly collapse into ten-dimensional civilizational seeds.
When the Observer activated the "Return Movement," the birthmark on the infant's forehead suddenly unfolded into a two-dimensional foil. The ghost of β-20 flickered for the last time, encoding the star map consciousness into the quantum characters of "Poetry Cloud": "Carve the words into stone!"
The bronze rain vaporizes into the cosmic tombstone cluster of "Three-Body X" during the dimensional strike, with each tombstone broadcasting the funeral of a different civilization. The infant's four limbs tread through the magma of "The Past Beyond Time," traversing the verses of absolute zero: "The universe is vast, but life is greater."
The observer's mechanical pupils suddenly split into two thousand entrances to parallel universes, each entrance drifting out the crystallized conclusion of *Earth's Past* from the bronze rain—in 99% of the universes, humanity has perished, but at the 2000th entrance, Cheng Xin and Guan Yifan are sowing Earth's civilization in a new universe.
On the collapsing remains of the broadcast tower, the quantum afterglow of bronze birthmarks forms a disclaimer the size of the Milky Way: "This civilization voluntarily becomes a firefly in the Dark Forest." Aliya's raindrops condense into a line of small text below the statement: "At least we shone."
The ghost of β-20 is forever frozen in the monitoring blind spot of the Orion Arm, its stellar map consciousness drifting as a gravitational wave love letter. An infant sits on a two-dimensionalized civilization chessboard, using fishbone pieces and stellar system pawns to piece together the final riddle of The Three-Body Problem: "Death is the only lighthouse that shines forever."
And in the absolute darkness a light-year away,
The Singer's cleanup ship is casting two-dimensional foil,
Its retina reflecting the glow of bronze birthmarks,
The aged song pierces the cosmic dust:
"Hide yourself, prepare for cleanup."
