Yun Siying, a supreme survivor from the end of the world, dies after detonating her power core to kill the fiancé and best friend who betrayed her and stole her spatial jade pendant. Upon opening her eyes, she finds herself in the body of Shu Siying, an eighteen-year-old girl in Dragon Country, 1973. The original owner had just died from severe beatings and neglect after being framed by Shu Ruxue, a girl who had recently returned to the family claiming to be the biological daughter. Shu Ruxue and the Shu family, particularly Tang Lingxue, had systematically abused Shu Siying, stealing her job and planning to send her to the countryside to replace Ruxue, who was supposed to go but avoided it through deception.
Yun Siying discovers that her spatial ability and crystal cores have traveled with her, though her power level has reverted to zero. She also finds that the lotus jade pendant, which had exploded in her previous life, now exists in this world and has merged with her, transforming her space into a luxurious courtyard with farmland and vast treasures. Realizing the truth, she uses a paternity test potion to confirm that Shu Ruxue is not the biological daughter of Tang Lingxue or Shu Guofeng, while Shu Siying is their true child. Yun Siying decides to sever all ties with the Shu family, demanding and receiving one thousand yuan for transferring her factory job to Ruxue, and legally changes her name back to Yun Siying.
After leaving the Shu household, Yun Siying uses her spatial abilities to prepare for her life in the countryside. She buys supplies, secures ration coupons, and arranges for her belongings to be sent to Mayun County, Lingyang Province, the same destination as Shu Ruxue. Before departing, she takes revenge on Shu Ruxue by administering a pill that causes chronic pain and infertility, ensuring the woman who killed the original owner suffers silently. She also buries the original owner’s remains in a proper grave, giving the deceased soul peace.
Yun Siying’s journey to the countryside marks the beginning of a new chapter. With her spatial dimension, supernatural powers, and accumulated resources, she is well-equipped to survive and thrive in the 1970s. Unlike the original owner, who was weak and dependent, Yun Siying is resilient, strategic, and unburdened by emotional ties to those who harmed her. She leaves behind the toxic family dynamics and the memory of her past betrayal, focusing instead on building a secure and prosperous life in the rural setting. The story follows her adaptation to the new era, her interactions with the local community, and her gradual restoration of power as she absorbs more crystal cores. Her ultimate goal is to live freely, free from the constraints of her previous life and the injustices she suffered in this one.
