Save NPC at the End of the World

What is the end of the world? When the world reaches the end, everything collapses, and in front of everyone, passages to other worlds appear, but there is nothing in front of them. At this time, a voice of a robot girl came from the sky, saying that the world was about to collapse, and asked the hosts to go to the next world. Where should I go at this time?
