Starry Sky Railway: I, Su Yu!

(A Starry Sky fanfic, following the plot, but not entirely; includes a female lead, but not entirely) My name is Su Yu. I used to be a human, but now I've become a bird. That's right, I transmigrated. The Survival System threw me directly into the body of a crow. That's fine, but why did this thing get mixed up?! Give me back my little brother! But none of that matters anymore. What matters is that I'm facing a phantom soldier right now, and it seems like it's about to kill me. Right now, all I can say is: "System Daddy, save me!!!" [After getting on board, the protagonist is the darling of the group, almost pampered bald; the setting is that of a veteran Honkai Impact 3rd player, who died before Starry Sky came out.]
