Creature Zero?

First of all, you still have to be imaginary, but you also have to have modern thinking, so you have to travel through time. I actually don't like time-travel novels. To write about sequential evolution, you have to have evolutionary means. At this time, you have to have cheat-like ones. I also don't like the so-called system novels, but I can't help it. My brain cells can't come up with any new settings. It must be because of insufficient evolution!
