Reform My Wicked Stepson? His Villainous Stepmother Flips the Table and Quits

Su Xi died in the apocalypse and transmigrated into a book, becoming the wicked stepmother of the story's not-yet-acknowledged villainous male lead. The little brat said, “One day I'll kill you, you wicked woman! I'll cut you in half and tear you to pieces!” The System said, “Hurry up and win him over with love, or he'll kill you! The four people who came before you all died horribly!” Su Xi simply started sharpening her knife. This child cannot be allowed to live. Win him over? Change him with love? He's going to kill you, and you still want to reform him? Are you out of your mind? Just kill him and be done with it!
