The world of Lyseno

From what I remember, I was thrown down a weird class with zombies to learn how to control different realities at the same time and choose the one most convenient for our survival. Which was dumb, why would we even need to survive without strong opponents anyways?

I got bitten twice and had to restart that universe twice, found out that zombies in Mexico for whatever reason were a bit faster, due to no food and people just going to the mountains and making no noise and then that people were mad at me for going to the city and bringing a small army of zombies with me, but eh.
