The Demon Lord Has Gone Mad

She wore black, with white hair, and was cold and merciless. The striking crimson mark between her brows spoke of an indescribable, demonic beauty. Only she knew that it was a humiliating mark left by her enemy. To exact her revenge, she cultivated forbidden arts and swept through the martial world with a blade in hand. Just hearing her name was enough to make people tremble with fear. Until the day she went mad. The martial world rejoiced, cheering that the demoness had finally gone mad from practicing martial arts. Little did they know that this was the beginning of the martial world’s nightmare.
