What Should I Do If I Am Not Reborn and Have Not Become a System?

[Death + immortality + no heroine + guidance + multiple worlds] Even before I died, I had begun to experience the world after death. The wind world is a new existence. Then I died and I was happy, But there's bad news: Upgrading is really, really slow. And good news: I've discovered a new way to communicate with humans. I haven't had any friendly interactions with the humans here yet. Looking forward to it.
