The Fleet Revealed

A Distant Enemy
Hubble II Discovery
Hubble II Space Telescope detects the wakes of roughly a thousand Trisolaran ships in interstellar dust. The discovery destroys humanity's last hope that the invasion might be imaginary.
Fear Made Visible
The fleet is still light-years away, yet its image changes politics, economics, and military planning immediately. Distance delays the attack but accelerates the psychological crisis.
The Probe Detachment

The First Advance
Ten Small Objects
Hubble II detects ten probes moving ahead of the main fleet. Their speed suggests that direct contact will occur decades earlier than the fleet's arrival.
A New Strategic Problem
Sophons already provide surveillance, so the purpose of physical probes is unclear. Their unexplained mission intensifies human anxiety rather than reducing it.
The Droplet's Arrival

The Gift That Watches
A Perfect Object
The first probe reaches the Solar System and appears as a flawless reflective droplet. Its beauty persuades humanity that it is a peace offering rather than a weapon.
Confidence Before Contact
The fleets capture it without resistance. Public sympathy toward Trisolaris rises, and Project Sunshine gains support before the true purpose of the object is understood.
The Fleet Massacre

The Droplet Attacks
Contact Becomes Destruction
The Droplet survives capture, kills the expedition team, and begins ramming human warships with impossible precision. Strong-interaction material makes it immune to every defense.
The Collapse of Confidence
The combined fleet is destroyed in minutes. Humanity's technological superiority proves illusory, and the entire civilization confronts the gap between advanced tools and genuine strategic understanding.
Negotiation at the Grave

The Enemy Answers
A Threat Made Personal
The Droplet approaches Earth, while Luo Ji prepares to activate his Cradle System and reveal Trisolaris to the galaxy. Sophons finally unfold before him.
Survival Through Exposure
Luo Ji demands that the probes and fleet turn away. Trisolaris accepts because the alternative is mutual exposure to unknown cosmic civilizations, creating the first true negotiation between the two civilizations.
