Steadfastly Being a Background Character

Xin Shensi, a twenty-seven-year-old civil engineer from modern China, dies after a long period of grief following her grandfather's death and transmigrates into the body of a madwoman in a martial arts novel called The Legend of Xue Yu Ying Yang. She awakens locked in an iron cage in the Xin family residence, where her sister Xin Yue'er pleads with her to help sabotage the wedding of Shan Hongyi by stealing her groom. Xin Shensi realizes she has become the 'crazy woman' who originally gave her internal energy to the novel's female lead, Tan Siyu, and who dies in the original story. Using her knowledge of the plot and the host's latent strength, she negotiates with Xin Yue'er, secures her release from the shackles, steals a gold bracelet, and escapes through a back window during the night. She finds shelter in a thatched shed by a firewood pond, where she reflects on her past life and accepts her new reality.

After escaping, Xin Shensi washes herself in a pond, catches fish with a reed, and hunts a rabbit in the mountains. She encounters a young girl named Li Man Xiu trapped in an animal snare, rescues her, and is taken in by Man Xiu's grandmother, Granny Li, at their rural home. Xin Shensi adopts the alias 'Shan Niang' and explains she fled an abusive father who wanted to demote her mother to a concubine. She agrees to teach Man Xiu how to weave decorative knots in exchange for room, board, and a small income from selling the crafts. Over the following weeks, she earns copper coins, improves her physical condition, and maintains a low profile, deliberately avoiding the jianghu conflicts while planning to accumulate enough wealth to buy land and live peacefully in the mountains.

Meanwhile, the Xin family, led by Xin Liangyou, launches an extensive search for the escaped madwoman after discovering her theft of the gold bracelet and her disappearance. Xin Liangyou is revealed to be a manipulative figure who imprisoned his daughter because of her profound internal energy, which he intended to use as a weapon. He had also murdered the original host's mother, Hong Shujuan, to maintain control. The search expands to nearby villages and beggar dens, but Xin Shensi remains hidden in Granny Li's household, gradually integrating into rural life. She continues teaching knot-making, earns steady income, and monitors her health, aware that the host's periodic Qi deviations may still occur.

The story establishes Xin Shensi's determination to survive without entangling herself in the martial world's power struggles, while the original novel's plot continues to unfold around characters like Tan Siyu and Meng Yao. Xin Shensi's escape sets her on a parallel path, one that avoids the tragic fate of the original madwoman while she seeks to build a quiet life far from the Xin family's reach. The narrative balances her internal reflections on her past life, her practical efforts to adapt to the new world, and the growing tension between her desire for obscurity and the inescapable pull of the martial arts community's conflicts.
