Organization Overview
The Earth-Trisolaris Organization (ETO) is the central conspiracy organization in The Three-Body Problem (the first volume of the trilogy). Founded by Ye Wenjie, it is the first — and only — underground organization in human history to actively collaborate with an alien civilization and betray the entire human species.
The ETO was born from Ye Wenjie's first communication with Trisolaran civilization at the Red Coast Base. After receiving Listener 1379's "Do not answer" warning, Ye Wenjie nonetheless chose to reply, inviting Trisolaran civilization to Earth. Thereafter, she began secretly reaching out to others who shared her despair about human civilization, gradually building a global underground network.
However, as the organization grew, severe ideological fractures emerged within the ETO. Different members had entirely different motivations for joining, and wildly divergent visions for what would happen after the Trisolarans arrived. These fractures ultimately crystallized into three major factions: the Adventists, the Redemptionists, and the Survivors.
The Adventists
The Adventists are the most extreme and most powerful faction within the ETO. Their core leader is the American oil magnate Mike Evans.
Evans's story is itself a tragedy of ecological idealism taken to its extreme. Born into a wealthy American family, he inherited a vast petroleum empire. But unlike his forebears, Evans held a near-religious love for the natural world. He poured enormous wealth into ecological conservation, attempting to save endangered species and protect primeval forests. Yet he repeatedly witnessed humanity's destruction of nature — species extinction, deforestation, environmental pollution — experiences that gradually transformed his environmentalism into a profound hatred of the human species itself.
Evans ultimately reached an extreme conclusion: humanity is a cancer upon Earth's ecosystem, and only the elimination of humans can save the planet. When he learned of Trisolaran civilization's existence through Ye Wenjie, he immediately recognized it as the instrument to realize his ultimate vision.
The Adventists' core belief can be summarized in two words: human extinction. They do not merely want Trisolaran civilization to rule Earth — they genuinely desire the complete annihilation of the human race. In their view, the very existence of humanity is a sin, and the arrival of Trisolaran civilization represents "redemption" for Earth's ecosystem.
Evans used his vast wealth to construct a massive ocean-going cargo vessel called "Judgment Day," serving as the Adventist faction's mobile headquarters and communication hub. The ship was equipped with technology for direct communication with Trisolaran civilization — the Trisolarans transmitted information and directives to Judgment Day via sophons. Evans monopolized the communication channel with Trisolaran civilization, giving the Adventists an overwhelming power advantage within the ETO.
Adventist members tended to be intellectual elites — scientists, philosophers, environmentalists — who generally held pessimistic views of human civilization, believing that humanity's innate selfishness, greed, and violent nature could not be overcome through its own efforts.
The Redemptionists
The Redemptionists held a far less extreme position than the Adventists. They did not wish for human extinction but hoped that Trisolaran civilization would serve as a "mentor" to guide human evolution.
Redemptionist members were typically intellectuals who held idealized visions of Trisolaran civilization. They viewed Trisolaran civilization as far more advanced than humanity, believing it possessed the wisdom and technology to solve all of human society's chronic ailments. In their vision, the arrival of Trisolaran civilization was not conquest but civilizational elevation — like a wise elder guiding a lost child.
This belief was, of course, extraordinarily naive. The Redemptionists completely ignored a fundamental fact: Trisolaran civilization's primary objective in coming to Earth was to acquire living space, not to help human civilization progress. Trisolaran civilization's attitude toward humanity was essentially no different from humanity's attitude toward ants — an advanced civilization has no concern for the welfare of a lesser one, especially when the two are in direct survival competition.
The Redemptionists reveal a deeply ingrained tendency in human psychology: when facing unsolvable dilemmas, people tend to place their hopes in an external "savior." This pattern recurs throughout human history — from religious faith to authoritarian worship, humanity has repeatedly demonstrated its tendency to surrender autonomy in despair.
Ye Wenjie herself initially belonged to something resembling the Redemptionist camp — her original motivation in inviting Trisolaran civilization to Earth was the hope that they might "save" a corrupt and fallen human society. But as time passed, she gradually recognized her own naivety, ultimately becoming the ETO's nominal spiritual leader while maintaining a certain detached distance from the organization.
The Survivors
The Survivors are the most "pragmatic" of the ETO's three factions and simultaneously the most morally contemptible. Their motivation is neither the idealistic dream of species extinction nor the naive vision of civilizational evolution, but naked personal survival calculation.
The Survivors' logic is simple: Trisolaran civilization is about to invade Earth, and this is an unchangeable fact. Rather than resisting in vain, it is better to pledge allegiance early, hoping for favorable treatment after Trisolaran civilization conquers Earth — to become collaborators, to serve the new rulers, and thereby ensure the survival of oneself and one's family.
This faction's membership is diverse — businesspeople, bureaucrats, military personnel, even ordinary citizens. They care nothing for grand philosophical questions or the fate of species, only for one simple, selfish question: how to survive the apocalypse?
The Survivors hold the lowest status within the ETO, despised by both Adventists and Redemptionists. The Adventists view them as faithless opportunists; the Redemptionists view them as idealless mediocrities. Yet the Survivors likely have the largest numbers, because in the face of extinction-level catastrophe, self-preservation is the most primal and universal instinctive response.
Operation Guzheng and the ETO's Destruction
The ETO's fate reaches its end in Operation Guzheng (the Guzheng, or "ancient zither," Operation). This is a precision military operation jointly planned by the Chinese military and intelligence agencies, targeting the Trisolaran communication records stored aboard Judgment Day.
The key technology of Operation Guzheng is the "flying blade" — ultra-strong filaments made from nanomaterials. At a specific point in the Panama Canal, the military pre-positioned several flying blade filaments stretching across the entire canal channel. As Judgment Day passed through at normal speed, these filaments — invisible to the naked eye — sliced the entire ship, along with everyone aboard, into dozens of thin sections, like cutting through tofu.
The brutality of Operation Guzheng is staggering. Hundreds of people on board died instantly, including Evans himself. Yet from a military and intelligence perspective, the operation was a perfect success — Judgment Day's communication systems and data storage devices were captured intact, giving humanity its first detailed knowledge of Trisolaran civilization's invasion plans, technological capabilities, and strategic intentions.
The ETO rapidly disintegrated after losing its core leadership and communication hub. Remaining members were either arrested or went into hiding, and the organization collapsed within months. Ye Wenjie was also arrested in the subsequent investigation and eventually died while revisiting the ruins of the Red Coast Base, reflecting on the past.
Legacy and Reflection
Though the ETO was destroyed, its impact on human history is irreversible. It was the communication channel established by the ETO that gave Trisolaran civilization detailed intelligence about Earth; it was the Adventist faction within the ETO that actively cooperated with Trisolaran civilization's "sophon blockade" plan against Earth's scientific community, suppressing the progress of humanity's fundamental sciences.
The ETO's three-faction structure is also Liu Cixin's profound dissection of human nature. Facing a civilization-level crisis, humanity does not unite — quite the opposite. People fracture into radically different camps according to their respective fears, despairs, and desires. Some choose destruction (Adventists), some choose fantasy (Redemptionists), some choose mere survival (Survivors) — while those who choose genuine resistance become, ironically, the silent majority.
