Junior Sister Lu Xiashan of the Yunyin Sect was tricked by her master since childhood into believing she was a "peerless good-for-nothing" and subjected to grueling cultivation, when in reality she is a divine-level prodigy fostered and tempered by her biological father, the Alliance Leader. After her master loses the sect plaque in a bet and flees overnight, she straps a firewood saber to her back and goes down the mountain to work and pay off the debts, while her senior brothers clumsily disguise themselves to protect her all the way. She smashes through trials and slays demons, all the way until she uncovers the truth of her heritage, discovering that she is actually the daughter of the Wanxian Alliance Leader. Raising her saber, the junior sister directs her fury toward her biological father and master—won't your consciences ache?
