Summary

Still disturbed by the collision‑experiment results, Wang Miao spends Saturday photographing Beijing with his mechanical Leica. Developing the film, he finds a countdown (initial value 1200:00:00) printed on every negative. The numbers adapt to the background contrast, appear even in lens‑cap shots, and precisely match the timing between exposures. Switching cameras and film rules out equipment defects, but the countdown only shows on pictures Wang himself takes—not on those taken by his wife or son. Desperate, he visits Shen Yufei. She refuses to explain and simply tells him to stop his nanomaterial research. After he shuts down the lab experiment, the visible countdown vanishes from his film. However, the numbers then appear as a persistent hallucination before his eyes, ticking away. An ophthalmologist finds no physical cause. When Wang threatens to restart the project, Shen says that on the 14th, “the entire universe will flicker” for him, and sends him a Morse‑code chart to prepare for observing the cosmic microwave background.

Key Events

  • Wang photographs city scenes with black‑and‑white film; the developed negatives reveal a precise countdown.
  • He systematically rules out camera and film problems by borrowing a digital camera and having his wife and son take photos.
  • The countdown appears only on pictures Wang shoots, regardless of the camera.
  • Wang visits Shen Yufei; she tells him to “just stop” his nanomaterial project and refuses to elaborate.
  • At Shen’s house, Wang briefly sees her husband Wei Cheng’s expensive HP workstation and mentions Pan Han’s arrival.
  • The countdown shifts from film to Wang’s vision, hovering persistently and unaffected by closing his eyes or looking at bright light.
  • Wang shuts down the reaction chamber for maintenance; the visible countdown stops.
  • Wang challenges Shen to prove the phenomenon is real by scaling it up; she replies that the universe will flicker for him on the 14th.

Character Development

  • Wang Miao moves from rational skepticism to near‑breakdown as the countdown proves untraceable. His decision to halt the national nanotech project shows he is willing to gamble on Shen’s warning, yet his anger at being manipulated hints at defiance.
  • Shen Yufei remains cryptic and authoritative. She does not explain the countdown, but her knowledge of Wang’s project and her calm insistence that he stop mark her as a conduit for forces far larger than the Frontiers of Science discussion group.
  • Shi Qiang appears only briefly, tailing Wang and making a sarcastic comment, reinforcing his role as an intrusive investigator.
  • Pan Han (a biologist and founder of the “Pastoral China” community) expresses hostility toward technological progress. His arrival at Shen’s house and his warning “Do not force our hand” suggest a coordinated faction within the Frontiers of Science.

Themes, Symbols, and Motifs

Theme / Symbol How It Appears
The Shooter and the Farmer hypotheses Wang recalls these two thought experiments while gazing at the CCTV building. The shooter (holes every 10 cm) and the farmer (turkey fed daily until Thanksgiving) both illustrate how observers can mistake a local pattern for a universal law. This directly echoes Wang’s fear that the laws of physics might be a temporary, local accident.
The countdown as a motif The countdown represents an inescapable external force that compels action. It shifts from film to vision, demonstrating that Wang cannot dismiss it as a trick. The precise timing creates dread: something significant ends when it reaches zero.
Nature vs. artificiality Wang’s photography style—seeking “wilderness” within the city, using black‑and‑white film—reflects a longing for authenticity. The supernatural numbers disrupt that order, suggesting that the natural world may be an artificial stage set.
Technological hubris Pan Han’s anti‑technology stance (comparing tech to cancer cells) provides a counterpoint to Wang’s faith in applied research. The countdown’s connection to the nanomaterial project implies that some technologies are seen as threats by unknown powers.

Why This Chapter Matters

Chapter 7 escalates the mystery from a weird physics coincidence to a personal, supernatural threat. The countdown cannot be explained by scientific means (camera defect, eye disease, or paranoia), forcing Wang—and the reader—to accept that something beyond known physics is at work. It introduces three key factions via the Frontiers of Science: Shen Yufei (inside knowledge), Pan Han (aggressive Luddite), and the unseen “they” who can manipulate Wang’s perception. The chapter ends with the most alarming promise yet: the universe itself will flicker, hinting at a cosmic‑scale intervention and raising the stakes far beyond a single researcher’s mental health.

Study Questions

  1. Why does the countdown appear only on pictures Wang takes, not on those taken by his wife or son? What does this suggest about the nature of the phenomenon?
    Answer: The difference eliminates a simple technical glitch (camera or film) and implies the countdown is targeted at Wang personally. It suggests the phenomenon can distinguish between individuals, either through some form of attention or through a connection to Wang’s mind. The narrative deliberately leaves the mechanism unexplained, making the event feel like a message rather than a random effect.

  2. What is the significance of the “shooter” and “farmer” hypotheses in this chapter?
    Answer: Wang recalls these hypotheses while trying to ground himself after dreaming of lawless billiard balls. The shooter hypothesis (holes every 10 cm as a law) and the farmer hypothesis (turkey expects food until Thanksgiving) both warn that the laws of physics as humans know them may be local coincidences, not universal truths. This bolsters Wang’s fear that the orderly world rests on “quicksand” and prepares the reader to accept that reality can be manipulated on a cosmic scale.

  3. How does Shen Yufei’s instruction to “just stop” the nanomaterial project relate to the countdown she claims will appear on the sun?
    Answer: Shen first says stopping the project will make the film‑based countdown disappear. When Wang does so, the countdown vanishes from his film but reappears as a hallucination. She then reveals that if he restarts the project, the countdown will appear on a cosmic scale—the universe will flicker. This ties the nanotech research directly to the interests of some superior force, implying that certain human technological developments are being monitored and can trigger drastic countermeasures.
