Darwinism Doesn't Apply Here

When you die, aren't you supposed to resurrect as some kind of human again?! Why didn't that happen to me? Now, I know what you're thinking. "Oh, so this guy became some kind of monster? Maybe a goblin or slime. Something weak." Well, I wish I was that lucky. Unfortunately, I didn't even get that much. I was resurrected as... an earthworm!
