My Online Game Connects to Another World

What should I do if I accidentally travel through time and the enemy from another world is too strong? What should I do if it's too difficult to defeat monsters and upgrade? What should I do if resources ore are hard to find? Let's make time travel an online game and let players all over the world work for you! Build a game and set the rules. In a different world, as long as the game covers the area, I am a god!
