Quick Transmigration: I Play the Passerby with the Script in Hand

[Film and TV Crossover, slow transmigration + no CP + System + lighthearted style + stays outside the main plot + very timid heroine] In every world, she stays outside the main plot, almost like a bystander. The story has an everyday feel and is told mainly from the heroine's perspective. She has a different identity in every world and is always a minor character from the show, either an original character or someone who appeared just once. If you like super-powerful heroines, you can take a detour! This heroine is cautious and timid, and she's quick to bend the knee. No CP, no CP, no CP!!! The first world will be more detailed and have some romantic entanglements, but there'll be very little of that later. The heroine grows over time! Whose System is named Big Shot? Whose System casually strikes its Host with lightning, either burning or electrocuting them? Whose System does nothing but scam its own Host? Congratulations, Miss Su He, you got all three! Su He: “If you have the guts, get me a different System!” Big Shot (a dazzling bolt of lightning crackles around it): “Host, what did you just say? I didn't hear you.” Su He smiles ingratiatingly, her voice sweet (while thinking #*#*): “I was saying, how did I get such a great System? I'm so useless, I'm nowhere near good enough for a magnificent System like yours! Any old little System will do for me.” Big Shot (putting away the lightning): “Hmm, at least you know your own limits. But don't lose heart. With me guiding you, you'll definitely complete every mission successfully.” Su He: “Thank you, Big Shot!” Picking up lotuses in Mysterious Lotus Casebook (unfinished) Becoming a eunuch in Empresses in the Palace (unfinished) An unnamed concubine in The Story of Minglan (unfinished)
