"This is the portal that you three are going to enter tomorrow." She pointed to the portal that was on the screen. "It is going to be the biggest one and where the strongest monsters are going to get out of. You will be covered and don't have to fight those monsters but just a heads-up about the monsters that are appearing tomorrow."
We didn't react with that new information because we knew that if you want to go to another universe you have to get a lot of energy in one place and while we could also do that with the number of gods we have you need the technology to keep it open and not waste the power of the gods.
The reason that God could open portals to other dimension is because he was lucky to get the technology to do so otherwise, he wouldn't even be near as strong as he is now. He just stores some of his powers in a container and that power is then fed to the portal. It works as a battery and that is why it is so powerful.
