That Day, I Became a Frequent Visitor to Another World

As the branches of the world slowly close together, all the weirdness continues to mix. Things in the branch world continue to appear in the main world, the order is collapsing, and the world is being reorganized.

When the futures of different worlds gradually merge into one, some people resist the closing of the world line at all costs, while others cheer for the new world!
