Those immortals who overcame the calamity and became immortals, although hundreds of millions of people looked up and admired them, still had an infinite desire for strength. It is often said in the world that "there are people outside the world, and there is a sky outside the sky." When mortals ascend to heaven, they already have infinite scenery, but in the sky, it is said that there is a higher heaven and earth. The immortals who pursue the peak of power must go through the ninth heaven in order to reach the outer heaven!
