The nine continents of the world of cultivation are in turmoil, and the sword energy reaches the sky. Thousands of years ago, Xuanxiao Sword Master failed to ascend against the calamity, and his obsession was placed on the sword spirit. With the decline of all laws, the sword spirit transformed into a crazy sword cultivator, Xie Wuhuan, and slaughtered the entire clan, just to find the sacrifice of Bai Yue's birthmark and restart the Tongtian Formation. The destined person is Qing Ci, a young man with twin spiritual roots hidden by the way of heaven. He is proficient in metaphysics and is naturally capable of killing spirits. Xie Wuhuan wants to refine Qing Ci, but there are many demons in his heart when they get along day and night. Qing Ci broke the situation with love, fought with life, and repeatedly reversed murderous intentions. From being imprisoned in Hantan to fighting against the catastrophe together, falling in love and killing each other, the catastrophe of love turned into a sword. In the end, Xie Wuhuan gave up his sword bones to block the thunder disaster, and Qing resigned from his spiritual roots and changed his destiny. Love is the original sin, and love is destruction. Only one person is left to reach the top, and the world of mortals resumes its destiny.
