The narrative unfolds with a dramatic sequence where Sun Wukong and his companions face a calculated trap set by a malevolent demon. As the group attempts to cross a river, the ice beneath them suddenly gives way, plunging the Tang monk and his party into the frigid depths. The demon, having orchestrated the event, reveals his sinister motive: "I froze the river and waited for you to cross it. Once you are above me, I crack the ice open." By isolating the Tang monk from his protectors, the demon intends to consume him to "live forever." The monk is subsequently imprisoned within a "stone box" inside the "Residence of the River Turtle," setting the stage for a high-stakes rescue mission.
On the surface, Wukong realizes the gravity of the situation. He correctly deduces that the freezing temperatures and the sudden collapse were not natural phenomena but the result of the demon’s machinations. Acknowledging his own limited efficacy in underwater combat, Wukong delegates the task of luring the enemy to Bajie and Wu Jing. He instructs them: "You two must go down there and get the demon to come back up. I'll surprise him." This strategic division of labor highlights Wukong’s role as the tactical leader of the group, relying on his companions to draw the enemy into a domain where he can effectively utilize his "iron bar."
Bajie and Wu Jing execute their mission, confronting the demon at his lair. The dialogue is direct and tense; when questioned about the kidnapped master, the demon brazenly admits, "Yes... And I plan to eat him." A chaotic battle ensues, characterized by the sounds of weapons clashing—"Clang!"—and the scattering of river wildlife. To lure the demon toward the surface, Bajie and Wu Jing employ a ruse, pretending to be intimidated and swimming upward. The demon, blinded by arrogance, chases them toward the surface, unwittingly falling into Wukong’s trap.
The conflict escalates on the surface of the river, where the ice becomes a dangerous battleground. Wukong engages the demon with his iron bar, while the demon retaliates with a "large hammer." The intensity of the fight is captured through the vivid onomatopoeia of the struggle: "Bam!", "Boom!", and "Crash!" as weapons strike both the enemy and the fragile ice. Despite the intensity, the demon manages to strike Bajie and exploit the chaos to dive back under the water, successfully evading capture.
Following the demon's escape, the companions attempt to return to the palace to rescue the monk, only to find the entrance blocked by a "huge pile of rocks." Their physical efforts, with Bajie’s rake and Wu Jing’s spear, prove useless as their weapons bounce off the obstruction. Recognizing that the rocks are likely "held in place with magic," the companions realize that their brute force and tactical planning are insufficient against this supernatural defense. The story concludes with a moment of humility, as Wukong concedes the limitations of their current power: "We need Guan Yin's help." This shift from physical confrontation to seeking divine guidance marks the end of this particular chapter in their journey.
