Chapter 528: Seven Swords Slash Heaven Mountain! (5)

In the midst of the roaring thunder, the heavens and earth seemed to reverse, the wind and clouds paled in comparison, and the white sword light at this moment transformed again. It was no longer white, but... a thick, intense red light!

Under this agitation, an earth-shattering murderous intent emerged, as if in madness.
