An alternate world was merging with Earth! It wasn't just a simple apocalypse! Because it would devour everything! All creatures shrouded in the eerie mist would mutate, turning into all sorts of monsters! When the truth was laid bare, people were utterly despairing. Because the 'apocalypse' was alive! It was driving the alternate world to escape through the spacetime rift, merging with new worlds, while it took the opportunity to devour everything in the new worlds, constantly multiplying and evolving! It spread like a two-dimensional foil, constantly eroding everything around it. To survive, one could only escape through the spacetime rift to the next world, merging with new worlds, thus creating a large enough safe zone! ... Qin Xu won 80 million in the lottery!
