Xuanyuanlu

At the end of the Dao Yuan Period, Jiuzhou was in turmoil. The traces of the Seven Saints reappeared, and the evil spirit of the Four Swords of Killing Immortals gradually emerged. "The Seven Saints gathered together, Yin and Yang merged, and the five elements turned around and the world moved. The four swords were suspended in the air and the catastrophe reappeared. The Tao was destroyed and the Tao was born to realize the Hongmeng."
