Mo Xiaoxiao transmigrates and gets bound to a goofy Savior System, which tasks her with saving another world.
The silly System keeps insisting that it's an absolute beginner-friendly mode. It gives her the identity of three big shots' idealized first love, a beautiful and ethereal appearance, and an overpowered golden finger:
[This System is connected to the weapons armory of a cultivation world and offers a pick-a-weapon feature, protecting the Host's life and safety.]
A top student in reading comprehension, she never expected the System's "pick any weapon" to mean literally "any weapon," as in a blind box.
Mo Xiaoxiao flies into a helpless rage: "How am I supposed to defeat a dragon with a storage space I got from the box?!"
Later, Mo Xiaoxiao discovers that this goofy Savior System really isn't professional at all. The weapon blind box was supposed to give her a weapon, but instead it gave her a demonic cultivator big shot with enough power to destroy the world. Great, now there's another unstable factor threatening to destroy this other world!
A fun story about a cowardly heroine saving another world with a goofy Savior System.
