Eight Maze Puzzle

Kong Ming’s Eight Maze Puzzle is a magical formation of stones by the river near Baidi, designed to confound and entrap an approaching army. When Lu Xun draws near after his victory, the formation surrounds his men with rising mist, flying sand and rocks, and stones that seem to move like living things. Kong Ming’s father-in-law leads the trapped soldiers to safety, but the encounter leaves Lu Xun so shaken that he orders a retreat. The stones thus achieve more than a momentary escape: they stop Wu in its tracks and become the formation’s enduring claim to fame.

Form and Setting

The formation is made up of eighty to ninety piles of rocks. Their apparent stillness is deceptive: as Lu Xun’s men investigate, mist rises from them, and a sudden wind brings a barrage of sand and rocks. The piles then shift in terrifying patterns, as if alive. The physical arrangement becomes a maze whose power lies in disorienting those who enter it, rather than in any visible wall or conventional weapon.

The puzzle stands beside the river as Lu Xun’s forces approach Baidi. Local people tell Lu Xun’s men that Kong Ming had the rock piles made and that the strange mist has arisen from them ever since. Their account supplies a history for the unsettling phenomenon, but the soldiers do not understand how the stones work before they are caught in its effects.

Lu Xun’s Entrapment and Escape

The strange apparitions alarm Lu Xun. Suspecting an ambush, he halts the army and sends men to investigate. Their search finds no enemy, only the rock piles and the mist above them. As the wind rises and sand and rocks strike the men, Lu Xun recognizes that the army has been deceived by Kong Ming’s device; he is unable to retreat and fears for his soldiers’ safety.

An old man appears unexpectedly and identifies himself as Kong Ming’s father-in-law. He explains that the formation is a magical spell called the Eight Maze Puzzle, then raises his stick and guides Lu Xun and the terrified soldiers out. The episode makes escape depend not on Lu Xun’s military command but on the intervention of someone who knows the maze and can lead the trapped men through it.

Retreat and Military Consequences

Although Lu Xun has triumphed, the encounter overturns his confidence in advancing. His commanders urge him onward, but he orders a retreat. He explains that the rocks themselves do not frighten him; he expects Cao Pi to exploit the opportunity to attack. Two days later, news arrives that hundreds of thousands of Wei troops have massed on the border. Lu Xun says he expected this and has already set plans in motion to stop them.

The formation therefore has a consequence beyond the danger within its stones. Its appearance interrupts Wu’s advance and prompts a withdrawal at a moment when Lu Xun anticipates a larger threat from Wei. The retreat is not presented simply as panic: Lu Xun gives a strategic reason for it and claims to have prepared for the new danger. Yet his own army has just been forced to rely on an unexpected guide to escape Kong Ming’s spell, underscoring how thoroughly the formation has unsettled the situation.

Reputation and Narrative Significance

The poem attributed to Du Fu frames the formation as Kong Ming’s signal achievement against the tragedy of a divided land. Its stones remain by the river as a tribute to the magic that stopped Wu. This poetic remembrance shifts attention from the soldiers’ immediate terror to the lasting fame of the place: the puzzle is both a battlefield device and a monument associated with Kong Ming’s command of strategy and the supernatural.

The encounter also turns on a striking contrast between appearance and military certainty. The men find no ambush, yet the rocks become a trap; Lu Xun’s victory does not protect him from being deceived, and his army escapes only when Kong Ming’s father-in-law intervenes. The formation’s power lies in making the landscape itself unreliable. Its stones do not need to defeat Lu Xun’s army in open battle to change its course: they bewilder the soldiers, compel retreat, and remain behind as the visible sign of a victory achieved without a conventional engagement.
