All I did was to release my own monsters over all of them. And at the same time, I went to control new monsters from the surroundings.
Like before, with my arrival, and in half an hour all the portals would be closed. That made the fight end up between me and those races.
Controlling these cities and towns was easy now for me. Just take control of their gates either on the ground or under water, then clearing all the hostile forces there.
Like this I started a big massacre against these forces. To be fair, they were heavily burdened with the last big war losses with me.
So fighting so soon against me and having to clash against such fierce and evolved monsters left them no chance at all.
But that took more time than before. Taking control of big cities and towns took hours. Yet it was worth it.
I took another day to reach the southern coast, ending up at the coast of Mississippi.
