As he was about to leave, Di Tou suddenly found that there was some resistance on his left foot and couldn't help but look down to find that there was a large clump of dirt and a somewhat jagged rock stuck to the sole of his shoe. His face turning pale, Di Tou looked at where his foot had been placed and saw the milky white liquid surrounding the footprint, and a foreboding feeling welled up in his heart. Quickly finding an empty space that was safe from glue, Di Tou squatted down on the ground, took off his shoe, and tried to chip off some of the dirt on the shoe. He was mostly successful, and in the end, there was only a thin layer of dirt left on the sole of the shoe, but the problem was he couldn't get rid of the rock!
