Subway Survival: Start by Taking the Witch to Watch Commercials

One night later, all Blue Star people traveled to the subway survival world, and staying alive became everyone's first priority. Although this is a digital world, every survival need is real, such as water, food, supplies, and even upgrade materials... Every 12 hours, the subway will arrive at an unknown station. Outside the station, it may be a different world filled with monsters, or it may be a city that has fallen into zombies, or of course it may be an abyss with extraordinary demons... Players can upgrade, the subway can be upgraded, and the difficulty of the unknown world is also being upgraded!
