I Have a Rusty Knife That Can Kill Ghosts and Gods

There is a servant boy by the Zhuoshui River, holding an extremely heavy rusty knife and stepping onto the stage of the world. When the wolf princess, the feather princess, and the human princess gather around the boy, what kind of story will happen between them? The sage said: The instrument is inherently sinless, and the Tao is infinite. If you do it well, there will be more. If it is caused by evil, it will overflow. No matter whether you are a barbarian, a ghost, or a god, if you invade our mountains and rivers and enslave our people, I will kill you with one sword! ——Mo Han
