On Mount Wuyi, there stood a sheer cliff, approximately a thousand zhang high, where the local populace often gathered precious items like agarwood and jade found at its base. The Prefect, having heard of this, urged hundreds of artisans to spend three years constructing a Cloud Ladder, intending to ascend and explore the heights. Just as they neared the summit, a colossal foot extended from the mountain, its toes as thick as wooden poles, bellowing, "Descend immediately, or I shall kick you down!" The Prefect, struck with profound terror, hastily retreated. The moment the foot touched the ground, the Cloud Ladder decayed inch by inch, dissolving into ash that scattered and drifted on the wind.
