You're Playing the Villain, Rescuing the Protagonist's Mother at the Start?

Transmigrating into my own novel? Even as a villain, knowing the plot would make me invincible, right? Turns out, the world I transmigrated into is actually a composite novel world, and I'm destined to be a minor villain in the early stages! No worries~ I get rewards every time I steal an opportunity from a protagonist! Who says novel villains have no future? A medical saint descends the mountain? The Dragon King returns? ...With me here, don't even think about stirring up trouble!
