In ancient times, there was the art of celestial swords, and demons danced wildly. Since the beginning of Pangu, all kinds of demons have appeared and disturbed the world. The ultimate boss, the Red Shadow Demon Lord, destroys the world and seeks the elixir of love and goodness in the world, as well as magic. The world is in ruins, the Dugu Xiaoling clan, a sword-wielding practitioner, and the Tuoba Shiyu clan, a time-travelling girl. Bring everyone with you and use your sword to slay demons along the way.
