Blind Confidence
After nearly two centuries of technological accumulation, humanity had established a massive space fleet of over two thousand stellar-class warships. This fleet was the most powerful military force in the history of human civilization — each warship was a mobile city equipped with powerful weapons systems based on controlled nuclear fusion technology. The Asian Fleet, European Fleet, and North American Fleet each possessed hundreds of capital ships, with combined combat personnel exceeding one million.
After weathering the social turmoil of the "Great Trough" period, human civilization had entered a new era brimming with confidence. Although fundamental physics remained locked down by sophons, progress in engineering technology was still remarkable. Humanity had mastered controlled nuclear fusion, electromagnetic acceleration weapons, efficient space propulsion systems, and a series of other advanced technologies. Optimism pervaded society — people believed that with the massive scale of two thousand stellar-class warships, humanity could handle any threat from the Trisolaran civilization.
When the first probe from the Trisolaran fleet was detected approaching the solar system, humanity's reaction was not fear but excitement. The probe was small — only about three meters long, droplet-shaped, with a mirror-smooth surface. Military and scientific communities generally concluded it was merely a reconnaissance probe or peace emissary; given the fleet's scale and firepower, capturing or destroying it would be trivial. Humanity even viewed this encounter as an excellent opportunity to demonstrate its own strength.
The Spectacular Reception Formation
To showcase human civilization's dignity and power, Space Force command decided to greet the Droplet's arrival in the most spectacular fashion. Nearly two thousand stellar-class warships were deployed in an enormous formation — warships neatly arranged like a military parade in space. This decision was later proven to be a fatal error.
The formation deployment left minimal distance between ships and extremely limited room for maneuver. If the Droplet proved aggressive, the densely arranged fleet would be an ideal target. But at the time, no one believed a three-meter probe could pose any threat to two thousand massive warships. This judgment reflected a fundamental weakness of human civilization when facing unknown threats — the tendency to measure an opponent's capabilities by one's own experience and standards.
Physicist Ding Yi led a small investigation team aboard a shuttle to approach the Droplet first. When he observed the Droplet at close range, he was stunned by the absolute perfection of its surface finish. The Droplet's surface had no irregularities at the molecular level — it was incomparably smoother than any man-made material. Ding Yi quickly realized what this meant: the Droplet's surface was composed of matter held together by the strong interaction force (also known as the strong nuclear force). In normal matter, molecules are bound by electromagnetic forces of relatively weak strength; the strong interaction is the second strongest of nature's four fundamental forces, roughly one hundred times stronger than electromagnetic force. Material sustained by the strong interaction possessed a strength completely beyond human reach — no human weapon could leave even a single atomic scratch on its surface.
In the final moments of his life, Ding Yi grasped the catastrophe about to unfold. But it was already too late.
Thirty Minutes of Slaughter
The Droplet commenced its attack. It suddenly accelerated at inconceivable rates, shooting into the densely arranged fleet formation like a lethal bullet. The Droplet used no weapons — it was itself the weapon. With the absolute hardness of its strong-interaction surface and extreme flight speed, the Droplet directly penetrated the first warship's hull. A stellar-class warship that humanity had spent decades building was transformed into an expanding plasma fireball in the instant the Droplet passed through it.
The Droplet shuttled through the formation at extreme velocity, each penetration destroying a warship. Its trajectory traced precise geometric patterns — first penetrating all warships along one line of the formation sequentially, then turning to the next line. This attack pattern possessed cold efficiency: the formation's dense arrangement meant the Droplet barely needed to waste time moving between warships, with minimal intervals between each successive penetration.
Human counterattacks were completely ineffective. Electromagnetic shells, nuclear warheads, laser weapons — all attacks against the Droplet's strong-interaction surface were like breezes against rock. The Droplet did not even need to evade any attack, as human weapons simply could not inflict any damage upon it. This was not a battle but a one-sided massacre.
In under thirty minutes, nearly two thousand stellar-class warships were reduced to debris and fireballs in space. Over one million military personnel perished in the disaster. Only a handful of ships whose commanders made the decision to flee at the battle's outset survived — among them the "Natural Selection" and several other vessels that would later play important roles in human history.
The End of Fantasy
The catastrophic defeat of the Doomsday Battle fundamentally altered humanity's mentality and strategic direction. Nearly two centuries of optimism turned to ashes in thirty minutes. Humanity finally recognized that the technological gap could not be bridged by building more warships — when an opponent possessed technology whose theoretical foundations humanity lacked entirely, numerical superiority was meaningless.
The deeper blow was psychological. Two thousand warships — the ultimate military force built with the efforts of several generations — proved helpless before a three-meter probe. The disparity in power exceeded anyone's imagination. It destroyed not only the fleet but humanity's confidence as a civilization. "Bugs" — the Trisolaran civilization's derogatory term for humans — felt cruelly apt in that moment.
After the Doomsday Battle, humanity was forced to completely abandon the fantasy of opposing the Trisolaran civilization through military power. It was against this backdrop of despair that Luo Ji — the forgotten Wallfacer — finally found the opportunity to demonstrate the power of the Dark Forest principle. Humanity's only way forward lay not in the number of ships or the strength of weapons, but in understanding and leveraging the rules of the universe itself.
