Summary

Princess Dewdrop, Auntie Wide, and Captain Long-Sail reach the coast opposite Tomb Island, where Prince Deep Water appears as a giant. They discover that He’ershingenmosiken bath soap creates foam that pacifies the ferocious glutton fish. Using a bar of the soap as a floating shield, they cross to the island. As they approach, the prince shrinks to normal human size because he does not obey the laws of perspective: he appears the same size at any distance. After a blood test confirms Dewdrop’s identity, the prince agrees to return and confront the usurper Ice Sand. The painter Needle-Eye cannot paint the prince because Western perspective fails, so Ice Sand faces him directly and is killed when he misjudges the distance. Needle-Eye commits suicide, but Long-Sail burns Dewdrop’s portrait, rendering the umbrella safe. Dewdrop declines the throne, choosing instead to sail away with Long-Sail. The Storyless Kingdom remains forever isolated.

Key Events

  • Dewdrop, Auntie Wide, and Long-Sail observe Prince Deep Water as a giant on Tomb Island; he does not respond to their calls.
  • A floating basin and soap foam reveal that He’ershingenmosiken bath soap renders glutton fish docile.
  • The group improvises a boat and uses the soap to create a foamy path across the sea, disarming the glutton fish.
  • Upon landing, the prince shrinks to ordinary height; his followers demand a blood test to verify Dewdrop’s identity.
  • The test confirms she is Princess Dewdrop, and the royal siblings embrace.
  • Deep Water and his followers return to the mainland in two boats, retracing the soap-foam trail.
  • Ice Sand’s cavalry surrounds them, but the soldiers’ awe of the foam path makes them hesitate.
  • Deep Water proposes a direct confrontation with Ice Sand at the palace.
  • Needle-Eye attempts to paint Deep Water but finds it impossible because the prince defies perspective; he warns Ice Sand and later commits suicide.
  • Ice Sand and Deep Water duel; Ice Sand cannot judge distance and is stabbed.
  • Long-Sail finds Needle-Eye’s studio, discovers Dewdrop’s portrait, and burns it, ending the umbrella’s threat.
  • Dewdrop decides not to become queen; she and Long-Sail sail away on a white-sailed boat, leaving the kingdom without further stories.

Character Development

  • Princess Dewdrop: Grows from a sheltered, anxious fugitive into a decisive leader. She insists on crossing to Tomb Island, braves the glutton fish, and ultimately rejects the throne in favor of freedom and exploration.
  • Prince Deep Water: Revealed as a calm, steady figure marked by twenty years of exile. His peculiar perspective—he appears the same size at any distance—becomes both a plot device and a symbol of his unchangeable nature. He shows no bitterness and immediately supports his sister.
  • Captain Long-Sail: Moves from cautious guide to committed companion. His practical skills (rowing, assessing danger) complement Dewdrop’s courage. He burns the portrait without hesitation, prioritizing Dewdrop’s safety over aesthetics.
  • Ice Sand: The usurper’s cruelty is underscored by his past betrayal of Deep Water. He remains composed until Needle-Eye’s failure, then meets a deserved end, undone by his own inability to understand perspective.
  • Needle-Eye: The painter’s rigid adherence to Western perspective makes him unable to capture Deep Water. His suicide reflects his artistic despair; he prefers death to facing a world that defies his craft.
  • Auntie Wide: Remains protective of Dewdrop, skillfully handling the umbrella. Her role diminishes after the portrait is destroyed, allowing Dewdrop to act independently.

Themes, Symbols, or Motifs

  • Perspective and perception: The prince’s defiance of perspective literalises the idea that truth looks different depending on distance. Ice Sand’s defeat stems from his inability to perceive reality accurately.
  • Freedom versus security: Dewdrop chooses a dangerous, story-filled life over the safety of a known kingdom. The Storyless Kingdom remains stagnant because its people prefer isolation.
  • Art and limitation: Needle-Eye’s failure represents the limits of a single worldview. Western perspective cannot capture something that does not obey its rules, mirroring the novel’s theme of cultural and scientific paradigms.
  • Foam as a protective barrier: The He’ershingenmosiken soap foam pacifies destruction (the glutton fish) and enables passage. It is light, precious, and temporary—like the fragile bridges characters build between worlds.
  • The umbrella: A symbol of constant vigilance; once the portrait is burned, the umbrella becomes harmless, showing that external threats can be neutralised by removing their source.

Why This Chapter Matters

This chapter completes Yun Tianming’s third fairy tale, which the human and Trisolaran worlds have been decoding for clues to survival. The tale’s central “law” – that a person can appear the same size at any distance – may encode a deeper cosmic principle (e.g., curvature propulsion or dimensional manipulation). More immediately, it resolves the love story of Dewdrop and Long-Sail, offering a bittersweet ending of chosen exile. The chapter also underscores the novel’s recurring contrast between closed systems (the Storyless Kingdom) and open ones (the wider universe). The prince’s defiance of perspective further echoes the novel’s challenge to conventional scientific assumptions.

Study Questions and Answers

  1. Why does Needle-Eye fail to paint Prince Deep Water? What does this reveal about the story’s worldbuilding?
    Needle-Eye cannot paint the prince because Deep Water does not obey the laws of perspective: he appears the same size no matter the distance. In the tale’s universe, this is a fundamental property of certain beings. It reveals that the fairy tale operates on rules different from our own, hinting that higher-dimensional physics (curvature propulsion, multi-dimensional beings) may be embedded in the fabric of Yun Tianming’s story.

  2. What does Princess Dewdrop’s decision to leave the kingdom tell us about her character growth?
    Dewdrop begins as a passive victim of palace intrigue. By the end, she actively chooses a life of uncertainty, exploration, and autonomy. She rejects the throne because she values stories and experience over power. This mirrors the novel’s broader theme: a willingness to risk the unknown (like the human fleet’s escape) rather than accept a static fate.

  3. How does the He’ershingenmosiken bath soap function as both a practical tool and a symbol?
    Practically, the soap’s foam pacifies the glutton fish, allowing safe passage across the deadly sea. Symbolically, it represents the rare, costly bridges that enable change. The soap is made from wind-driven bubbles, collected only by the fastest riders – an image of fleeting, hard-won opportunity. Its lightness (weightlessness) suggests that solutions to seemingly impossible problems can be found in the unexpected.
