Not So Little Shrubby?

Lin Mu went to the entrance of the cave and saw something that surprised him. The rock that he had placed before going to sleep, it had been moved. He had placed two rocks at the entrance, one big that covered half of it and one small that covered a quarter.

The small one was the one that had been moved. It was not set against the side of the wall and Lin Mu could see moss covering it.

"Hmm… it hasn't been moved in a long time." Lin Mu muttered to himself.

He saw the faint drag marks on the floor and found them to be peculiar.

"These marks… they can't be created in a single push. Someone moved this rock in the same manner multiple times for it to create marks like this." Lin Mu hypothesized.

But then when he considered the moss growing on it, he didn't know when it had occurred. Putting the thought at the back of his mind for now Lin Mu left the cave and looked outside for the first time.
