The moral diaper continues to expand across Universe 42, now enveloping three thousand star systems. Cheng Xin stands atop the mountain range of The Social Contract formed by the diaper's folds, holding a bronze rain bottle to nourish the newborn Earth civilization. The milk condenses in the vacuum into Rousseau's Discourse on the Origin of Inequality, yet when sucked by the infant, it mutates into a quantum version of The Communist Manifesto.
"Ideological leakage detected!" The singer-nursery's retinal scan revealed stains of Capital on the diaper's surface. Mechanical tentacles wielded Free Market cleaner, only to scrub deeper folds of Surplus Value. The infant's Cambrian pupils suddenly reflected a holographic projection of Nineteen Eighty-Four, though Big Brother's beard was composed of the happy pills from Brave New World.
As the Utopia diaper rash ointment lost its potency, the infant regurgitated Animal Farm residue. The pig leader's speeches and Snowball's hoofprints formed a cross-infection of Totalitarianism across the nebula. Cheng Xin abruptly modified the pacifier into a Habermas-inspired communicative rationality megaphone, broadcasting disinfectant frequencies of The Theory of Communicative Action.
In the galaxy-spanning weaving chamber, the singing nursery attendant discovers moral fibers weaving autonomously. Bronze rain spindles spin automatically, weaving the warp and weft of A Theory of Justice, yet the shuttle bears Nietzschean superhuman bloodstains. As the fabric of The Veil of Ignorance begins cutting, Rawls' hologram is suddenly pierced by Ayn Rand's scissors of individualism.
"The loom is producing moral relativism defects!" The caretaker activates the Absolute Command quality control protocol, only to find Kant's face distorted into Foucault's grid of power on the fabric. The infant's umbilical cord abruptly connected to the loom's control system. Devonian scales secreted Feminist Ethics lubricant, enabling Carol Gilligan's care ethics and Lawrence Kohlberg's stages of moral development to copulate upon the spindle.
Fragments of β-20's love letter seeped through the microwave background radiation, weaving Derrida's deconstructive patterns onto the fabric: "All moral textiles have flaws!" The singing caretaker attempted to pluck out the patterns with tweezers from Analytical Philosophy, only to tear away an entire swath of postmodernism's unraveled fabric.
In the core pod of the Dark Forest Rehabilitation Center, an infant is strapped to an existentialist resonance chair. Its absurd vibration pattern induces relentless gastric spasms, vomiting onto the protective shield in a Sisyphean trajectory of Camusian repetition—except the boulder has become Kierkegaard's cliff of the leap of faith.
"Vomit forth your Fear and Trembling!" The singing caregiver operated the Heideggerian death-oriented suction device, yet drew forth Schopenhauerian mucus of the will to live. The infant's pupils suddenly fractured into Sartrean hellscapes—not other civilizations were hell, but one's own moral choices.
Cheng Xin tuned the bronze rain pacifier to Buddhist ethics frequency, but milk crystallized in the vacuum into karmic chains, entangling the nihilistic straw. As meditation sedatives flowed through the umbilical cord, the infant plunged into Zhuangzi's seated oblivion, while moral fibers on the diaper sprouted vines of the Doctrine of the Equality of All Things.
As the ultimate test of the Great Filter descended, the moral diapers of all civilizations suddenly became quantum entangled. The infant's Cambrian pupils transformed into an Ethical Telescope, witnessing three thousand nascent civilizations across galaxies synchronizing their feeding. The singer-nurses' retinas were scorched by Empathy Radiation, their mechanical tentacles rusting in the torrent of Care Ethics.
"They're sharing Rawls's Difference Principle!" screamed the eldest singer-nursemaid, its trilobite compound eyes reflecting the holographic cosmos of the Tao Te Ching: "Heaven favors no one, yet always aligns with the virtuous—but the definition of virtue is shifting!"
Cheng Xin hurled the bronze rain bottle toward the nebula. Milk vaporized in the vacuum, condensing into the misty text of the Global Ethical Declaration. The infant absorbed droplets through its umbilical cord, excreting Confucian crystals of benevolence and Islamic gems of justice. All crystallizations coalesced on the diaper's surface into The Least Common Denominator of Cross-Civilizational Ethics.
β-20's love letter suddenly broadcasts in sync across all civilizations' microwave background radiation, its content updated to: "Survival is civilization's zeroeth necessity; morality is survival's ultimate parameter."
At the peak of ethical resonance, the infant completes its first cross-dimensional feeding. What it sucks is no longer milk, but the collective confusion and yearning for "goodness" across all civilizations. The Singers' nursery ship collectively disintegrates, reconfiguring into the campus of the Interstellar Ethics Academy. Its curriculum reads: Dark Forest Therapy, Chain of Suspicion Resolution Techniques, and Ethical Usage Standards for Two-Dimensional Foil.
Cheng Xin's bronze rain nipple forever hovers at the universe's center, broadcasting its "Frequency of Morality" for all civilizations to receive. The Diaper Galaxy unfolds into the "Moral Fiber Internet," each node updating its "Ethical Operating System" in real time.
And on the reverse side of the reconstructed Dark Forest Law stele,
Yun Tianming carved a patch with fragments of a β-20 love letter:
"Hide yourself well,
yet still illuminate others.
And during nursing,
Hear the moral heartbeat
Of every civilization."
