Review Detail of Dark_Eterium in Infinite Evolution in The Apocalypse

When I was reading this I kept feeling something was missing, and only until I reached the chapter where he talked to the general I realized what that was. I don't know our Mc, and I don't mean his backstory, I mean I don't know why he acts like he acts, I don't know why he does A instead of B, and he does so just cause. His evolution options seem absolutely nonsensical to me, because it's never established what type of person he is. And if the lens through which we see your world are dull then the world will inevitably be as dull as a well.
