This was a piece of sheepskin on which half a mountain was drawn. Looking at the incomplete image and observing the two adjacent edges of the sheepskin roll torn open, one could tell that it was some part of a whole. Zhang Xiaohua first examined the graphics drawn on it carefully but didn't figure out anything. Even after flipping over the entire sheepskin, he didn't notice anything unusual.
"Strange. What is this? A treasure map? A will? Or a ink and wash painting?"
Zhang Xiaohua muttered to himself, then promptly released his infallible Divine Sense to study it, but the sheepskin didn't emit any unusual fluctuations, simply a normal piece of sheepskin.
