In 2025, "Infinity Trains" will appear simultaneously around the world. Every 24 hours, the selected person will be pulled into a ghost train code-named "Dawn" and enter a terrifying copy. Complete the dungeon to gain points and rewards. If you fail three times in a row or violate the rules, you will be wiped out. The train has a total of 99 stations, and those who arrive at the terminal station will get the "right to make a wish."
