In All the Worlds, I Quietly Revised the Protagonist's Script

When countless time travelers think they are performing their own legends, Little did they know that their script was being rewritten by an unknown NPC! The moment I get the script modifier, Only then did I know what a real protagonist is! These so-called sons of destiny, It's just a puppet pushed along by the script! Even more interesting is: I can secretly change the direction of anyone's script, But it won't leave any traces! You said you want to change your destiny against heaven? Sorry, the script has been changed, you are just a supporting role! You said this is your chance? Sorry, this is the background board I arranged for someone else! High energy warning ahead: Do you think you are the protagonist? No, you are just a gag in my script! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
