The Lone Hero

Dan Xia is a little girl with extraordinary abilities. She can fly through the heavens and burrow into the earth, and there's nothing she can't do. But even Dan Xia has to eat. The martial world is a hard place to get by these days. She has made a name for herself with the extendable Silver Moon Saber in hand, but she still needs to eat, and she's broke. She can't go around robbing people, so she heads to a mansion to see if they're hiring a gatekeeper.
