No male lead + female-led story + Celestial Master + Five Thunder Method + heroines' alliance
System: "I've detected that you're the most formidable woman in this world, so I've chosen you as the Host of this Stand-in System."
The purple-robed Celestial Master Ma Xiaoxiao awakened her System by accident while fighting a thousand-year-old demon to the death.
But she couldn't understand one thing: What did it mean to be a Stand-in System?
Ma Xiaoxiao: "What's a Stand-in System? Stand in for what?"
System: "Of course, you stand in for girls who are being bullied. Talk back, and fight back."
Ma Xiaoxiao: "Then do you know what I do?"
System: "No. What do you do?"
Ma Xiaoxiao: "I'm a purple-robed Celestial Master. I only know the Five Thunder Method. Do you want me to be a lightning stand-in and strike those people dead?"
System: "That might work, actually. But before you strike them dead, you have to make them regret it. That's how you'll earn rewards."
From that day on, the weather in this world often changed from sunny to cloudy, with thunderstorms in scattered areas.
