The treasure of this Mystic Nether Sect was a mountain rock with a mural engraved on it.
It was an ordinary-looking rock.
However, the content carved on the mural was extraordinary. There was a huge dragon-snake beast carved on it. This beast's body was very long and looked like a snake, but it had six pairs of flesh wings on its back.
Its head was like a crocodile's and looked sinister. Even though it was only carved on the murals, its monstrous ferocity still gushed over.
In the mural, its tail was nailed firmly by a huge nail, restricting its movements. At the same time, a thick chain connected to the nail and the other end was directly refined into the head of the dragon-snake beast.
As a result, the dragon-snake's head and tail were both restricted but it wouldn't be able to die easily. A long wound was torn open on its body, revealing the bones and tendons inside.
