Youyou's mortal mother was divorced and cast out by the Sect Master of Feiyun Sect, driving her mad. With nowhere to go, Youyou takes her mentally ill mother from place to place, begging for food. By chance, she activates a beast-taming system. A declining sect takes pity on the helpless mother and daughter and brings them back. Little do they know that good fortune is about to come their way: a divine beast egg that has lain dormant for over a century suddenly cracks, and a critically ill king beast miraculously recovers and becomes lively again. The once-fallen sect is destined to rise to its former glory. Youyou becomes the sect's young mistress and is showered with endless love, while her mother's madness gradually heals. When the ruthless father who abandoned them witnesses their transformation, he is filled with regret. At last, Youyou and her mother escape their miserable past and begin a peaceful, warm, and ordinary life.
