Kyushu Xuanlu is guarded by five immortal gates, but the ancient disaster "Return to Ruins" is sealed underground. Ten years ago, the trial formation of Baigu Town failed. Fuya Mountain, a small immortal sect in the border area, was designated as a "collusion and return to ruins" by the five major immortal sects, and all the sects were expelled. Xie Jingchen, a disciple of Fuya Mountain, swallowed the source of Guixu evil and helped the world suppress disasters for ten years, but he was called the Shadow Demon Lord by the world.
When he was young, Shen Zhaoye was retrieved from the mountain of monster corpses by Xie Jingchen. Later, he entered the Taiwei Sect and became the first sword holder. Many years later, the two reunited in the Town of Bones. One is the evil demon king who everyone shouts to kill, and the other is the coldest sword cultivator of the righteous path. Gui Xu wakes up and the old case is reopened. They have to work together to investigate the truth and save Jiuzhou.
Purpose: The truth must be revealed
