Du Wei took some people out of the city for a trip, and because they rode fast horses, he felt unwell when he returned home and went to rest.
He slept until dark and upon waking, he called for someone and asked, "Have those two people been found?"
The person answered, "My lord, they have not been found. It's as if those two people vanished into thin air. We've searched several mountains and haven't spotted a single trace of them, especially since there are no footprints made by walking."
Du Wei let out an "Oh?" and said, "Vanished into thin air?"
The person nodded, "My lord knows that in the winter, the mountain forests are deserted, there are no hunters living off hunting within a hundred li, and in the wild grass and bushes, there are no footprints."
Du Wei narrowed his eyes, "What about the road leading to Duankou Cliff? No footprints there either?"
The person shook their head, "None were discovered."
