Summary

The international military task force debates how to capture the Trisolaran data aboard Judgment Day without allowing the crew to destroy it. After conventional weapons fail to meet the requirements of simultaneous elimination of all personnel, Shi Qiang proposes using Professor Wang’s nanofilament “Flying Blade” strung across the Gaillard Cut. The plan is adopted with the code name “Operation Guzheng.” At the canal, Wang witnesses Judgment Day pass through the invisible net; the ship is sliced into dozens of half-meter-thick segments, killing everyone aboard, including Mike Evans. The data is recovered. A subsequent interrogation reveals that Ye Wenjie’s idealized view of Trisolaran civilization is shattered when she learns the true nature of the messages.

Key Events

General Chang opens the meeting by stating the objective: capture the Trisolaran messages stored on Judgment Day without giving the crew time to destroy them.
Various military officers propose ball lightning, neutron bombs, nerve gas, concussion bombs, and infrasonic weapons—all rejected because they cannot kill everyone simultaneously or would damage the data.
Shi Qiang draws two parallel lines on the table representing the Panama Canal, uses cigars as pillars, and explains his plan: string ultrastrong nanofilaments (Flying Blade) between two shores and let the ship sail into the net.
Colonel Stanton initially scorns Shi Qiang but later respects him; the plan is accepted after Wang confirms the material is available.
The team chooses the Gaillard Cut, the narrowest point of the canal (150 m wide), and string fifty filaments 50 cm apart.
Four days later, Wang and Stanton wait at the canal. The “zither” of filaments is raised as Judgment Day approaches.
The ship passes through the invisible net. At first nothing happens, then an antenna breaks, a crew member is sliced in half, and the engine is destroyed. The entire ship separates into forty-plus slices and crashes into the shore.
Soldiers and helicopters secure the wreckage; fire suppressants are dropped. The Trisolaran data (28 GB) is recovered because the smooth cuts did not destroy the storage media.
Three days later, an interrogation reveals that Ye Wenjie’s hope that Trisolaran civilization possesses advanced morals was naïve. The interrogator tells her the reality of the captured messages shatters her fantasies.

Character Development

Shi Qiang: Previously portrayed as a blunt, streetwise detective, he reveals his deep tactical creativity. His “out-of-the-box” thinking—inspired by criminals he once chased—solves the seemingly impossible problem. He earns grudging respect from Colonel Stanton.
Wang Miao: A pacifist scientist, Wang is horrified by the operation’s brutality. He trembles, nearly breaks down, and briefly hates Shi Qiang. His moral conflict highlights the human cost of defending civilization.
Colonel Stanton: Initially dismissive of Shi Qiang, Stanton undergoes a visible shift—first contempt, then silence, and finally offering his cigar box as a gesture of respect. His rambling about history and the space elevator shows his own psychological struggle.
Ye Wenjie (interrogation scene): Her faith in “advanced” Trisolaran civilization is exposed as wishful thinking. The interrogator confronts her with the cold data that will likely prove her wrong.

Themes, Symbols, or Motifs

The Cold Calculus of Survival: The operation requires sacrificing the crew of Judgment Day, including possibly innocent cable workers and the Panamanian pilot. General Chang tells Wang not to “concern yourself” because the survival of human civilization overrides individual lives.
The Nanofilament “Zither” as a Symbol: The invisible net represents the razor-thin line between technological triumph and moral horror. It is both elegant (like a musical instrument) and lethally efficient.
Dehumanization of the Enemy: The Trisolarans remain abstract; the immediate enemies are human traitors. The military treats them as an “enemy from outside human civilization,” justifying extreme measures.
Shifting Perspectives on War: Stanton reflects that all previous wars now seem “insignificant” compared to the Trisolaran threat. This motif repeats throughout the chapter, emphasizing the scale of the challenge.

Why This Chapter Matters

Chapter 32 is the first major offensive action taken by humanity against the Trisolaran threat. It demonstrates that conventional military thinking fails, and only a non‑traditional idea—Shi Qiang’s—succeeds. The operation retrieves the Trisolaran messages, which will drive the plot forward in later chapters. It also forces characters (and readers) to confront the ethical price of survival: the deliberate killing of everyone aboard Judgment Day to secure intelligence. Finally, it sets up Ye Wenjie’s disillusionment, a key emotional and philosophical turning point.

Study Questions and Answers

1. Why were conventional weapons (ball lightning, nerve gas, etc.) rejected for Operation Guzheng?
Every weapon considered either could not kill all personnel simultaneously (ball lightning), took too long to incapacitate (neutron bomb, nerve gas), or would damage the computer equipment (concussion bombs). The requirement was to eliminate all enemies within ten seconds of detection without harming storage media.

2. How does Shi Qiang’s background as a criminal cop contribute to the plan?
Shi Qiang explains that criminals excel at “out-of-the-box thinking.” He recalls a case where thieves stole a car from a moving train using only wire cable and steel hooks. This unconventional logic leads him to imagine slicing a ship rather than bombing it.

3. What is the significance of Wang Miao’s emotional reaction during the operation?
Wang’s trembling, hatred for Shi Qiang, and near-breakdown show that the moral cost of the operation is not lost on him. He represents the human conscience: even in a necessary act of defense, the violence is traumatic. His reaction contrasts with Stanton’s stoic calm, highlighting different ways people cope with the “new reality.”
