It was the skin of an amiable-looking old man, who wore monk's clothing. Su Yu had a deep impression of him. He was none other than the elder who had recommended them to the Eighteen Linked Mountains, Jiu An!
Su Yu took the skin and stroked it. It seemed from the slit upon it that it had just been opened recently. Moreover, there was still a faint trace of Ghost Energy remaining within it.
"Sheng Ge, do you know what's going on with this?" Su Yu's wrist shone as he summoned Sheng Ge.
After she came to stand beside him, her gaze immediately fell upon the skin and she furrowed her brows as she said, "It's the Ghost Clan's Painted Skin. After obtaining a living being's skin, they can use a special method to refine it into a skin that ghost's can wear. This allows them to disguise themselves as that living being! Such a method deceive most people, and it's difficult for anyone, apart from ghosts, which are sensible to Ghost Energy, to recognize it."
