The Dark Demonic Eye!

Wang Baole had first read about the Demonic Eye Art in his Dark Dream. It was a strange and bizarre mystic art that had originated from an ancient civilization that was now extinct. Its records stopped at its Nascent Soul realm techniques. The Dark Sect wouldn't have paid it much mind because of that, but its incredibly destructive power had resulted in it being listed as one of the three most powerful Nascent Soul realm mystic arts that the Dark Sect had ever come across. In fact, when practiced alongside the Dark Art, it would display a power that would make it the most powerful mystic art the sect had ever seen at the Nascent Soul realm. It had only been abandoned as a practical mystic art because it was incomplete.

The mystic art focused on killing. There were five levels to it. Each new level brought a transformation to the cultivator's cultivation, as well as his physical strength and speed. The latter two would be doubled at every level.
