After her artisan family is brutally massacred, Nan Yanzhi becomes the disciple of Zhuang Wujiu. Under her guidance, she transforms from an innocent young woman into a ruthless survivor willing to crawl through the mud for revenge. Clinging to the few clues left behind, she infiltrates the mysterious Lingya Tower alone. Rumor has it that everyone who enters the tower is turned into a beast in its deadly arena, and none ever make it out alive. Just as Nan Yanzhi believes she has no one to rely on, she discovers that Zhuang Wujiu has appeared within Lingya Tower—as one of its highest rulers.
