Senior Miscellaneous Soldier from Another World

Is it lucky or unlucky? I finally traveled to a different world, but my race is not human. I can upgrade, but I can only upgrade to level ten. I can learn many skills, but they are of no use. How can I survive in this world where gods and demons are everywhere, and there are as many as *100 levels? What else can be done? Use your brain! No matter what, you can't die!
