Apocalypse: I'm Just a Boy, Yet I Became a Higher Race

(Adorable boy, wish-fulfillment, no System, trapped in a dead world) I transmigrated and became a nameless member of a superior race, able to travel back and forth between different worlds. But something was off about all this. Who created me, and why was my travel between worlds so unpredictable? I wanted to find out, so I kept traveling between worlds. But one day, I accidentally got stuck in one of them. A post-apocalyptic world. But why are a bunch of little boys staring at me with tears in their eyes? Holy crap, calm down! I’m a guy!
