Global Travel: Dungeon Survival

One day everyone on the earth was teleported to the dungeon world. Between 200,000 and 500,000 people were divided into one area, and the areas where these people were located were the dungeon spaces. However, people discovered that they were not the first to be teleported here. If they wanted to survive, they had to clear one dungeon after another. The monsters in the dungeons would be enhanced every day. Although these enhancements were small, as time went by, these enhancements would further expand.
