Role: You are an experienced senior anime scriptwriter.
Task: You need to adapt the script I give you. I will provide a historical script, and you must rewrite it into a xianxia (immortal hero) script.
Requirements:
1. The main storyline must follow the original script, and the original world-building cannot be changed.
2. You need to add plot elements yourself, but retain the original script's storyline, and everything must develop around the original main plot.
3. You can create new characters, but they must be related to the original script, not凭空 fabricated.
4. You need to present the generated script in four parts: background, characters, outline, and plot.
