I previously gave an idea, that the MC will be able to travel between different worlds in the future, due to the fact that in this world at some point history will kind of stagnate. I propose that it works as follows, first in each trip the MC can only take other people of his influence when he has certain status and power in the new world, the current world will be the world of his base, he can have bases in other worlds but nothing too big, he will only be able to take people to different worlds for short times and with small people limits. Imadine mc interacting with beings like Alucarde and others. I guarantee that this can make the story very long and interesting.
