Star Railway: I, Su Yu! Railway Group Poultry

Introduction: (Xingqiong fan, follows the plot, but not completely; there is a female protagonist, but not completely) My name is Su Yu. I used to be a human, but now I have turned into a bird. Yes, I wore it. Gou System directly threw me into the body of a crow. Forget it, but why did I get this thing turned upside down? ! ! Give me back my little brother. But these are not important anymore. What is important is that there is a virtual pawn in front of me now, and it seems to be killing my son. Now, I can only say one thing: "System Daddy, please help me!!!"
