Transmigrated into the chaotic world of Northern Li, Jiang Chen finds himself in Snow Moon City, the pinnacle of martial arts under heaven. Following the death of a revered master, the city faces an influx of challengers seeking power and prestige. To maintain order, the three legendary City Lords establish the Ascension Pavilion, a deadly gauntlet where only the worthy may pass.

Jiang Chen, a new disciple with no apparent cultivation, is unexpectedly assigned to guard the fifth floor. However, he harbors a secret advantage: a mysterious System that allows him to set the rules of engagement. By transforming trials into bizarre quizzes and riddles, Jiang Chen baffles elite warriors who expect sword fights, not trivia.

As he charms his flustered sword-immortal master and outwits arrogant geniuses with his clever tongue, Jiang Chen quietly climbs the ranks. In a world governed by brute strength, he proves that knowledge—and a well-timed question—is the ultimate weapon.
