The Apocalypse Arrives, and I Gain Several Younger Sisters

Strange dreams, a world of immortals and martial heroes, a sister who appeared out of nowhere, the mutated Blue Star, and a bronze mirror sealed with blood. They all seem to be connected to the rift in the sky. But what does any of this have to do with me? Why do I keep dreaming about Chen Junlin? Why does Wan'er mistake me for Chen Junlin? And why did the bronze mirror save me? Is the other world really as it appears in my dreams, with immortals overlooking the heavens and wiping out all living beings with a flick of their horsetail whisks? Lin Yun must uncover the truth behind it all.
