A hardcore modern UFC champion is reborn as Ruan Jinwei, a delicate fifteen-year-old girl in ancient times. She comes with a younger brother who is always being bullied and a family in shambles. A rough-and-tumble soul in a girl's body, she has no interest in romance and spends the whole story building her career and protecting her brothers.
Luckily, she hasn't lost her fighting skills. Archery and hunting come naturally, and her nunchucks make bandits cry for their mothers. After all, no one knows that “Big Ruan” is a girl.
She protects Xiaobao and teaches him self-defense to deal with troublesome kids; she takes Damao and Ermao hunting and bandit-hunting to earn food, always keeping her brothers behind her; when she meets the icy secret guard Li Yan, they fight side by side and trust each other with their lives. One word, brother, and she'll risk her back for you. She can fight and take a beating, and she can also cook hearty, nourishing meals. This most fearsome “Brother Ruan” in the military camp makes a place for herself with her fists and gathers brothers with her loyalty. “You like me just because I'm a girl? Bullshit! I thought of you all as brothers...”
