Li Zhiyin, a young woman raised in the slums of Lanshan City, endures years of abuse from her adoptive parents who favored her younger brother. Her biological family, the wealthy Li clan, discovers her existence after a hospital mix-up caused by an earthquake eighteen years prior. In a tragic kidnapping incident, her biological parents and adopted sister Li Wuyou choose to save Wuyou, leaving Zhiyin to fall to her death. Reborn to the day before her biological family arrives, Zhiyin orchestrates the deaths of her abusive adoptive parents and rejects the Li family when they attempt to claim her. Instead, she chooses to become the adopted daughter of Shen Lianyan, a powerful and ruthless business magnate seeking an heir.
Shen Lianyan, also reborn and haunted by regrets from her past life, accepts Zhiyin immediately. During a medical evaluation, Zhiyin is revealed to possess a rare Level Ten combat implant tolerance, the highest possible score, making her a potential invincible cyborg. Her Humanity Value is initially recorded as one due to severe emotional trauma, but it rises to ten after Shen Lianyan defends her against the Li family. The Li family, particularly Wuyou and her brothers, are horrified by Zhiyin’s rejection and her new alliance with Shen Lianyan. Wuyou, who lacks any combat ability, fears losing her privileged status and plots against Zhiyin.
Zhiyin enrolls in North Yue Academy, an elite institution for the children of the wealthy and powerful. She befriends Yan Juexia, a spoiled but kind-hearted young master, while maintaining a cold distance from her biological brothers. The school becomes a battleground for influence among the city’s major families. Shen Lianyan instructs Zhiyin to build alliances with the young masters to secure business deals, while Zhiyin navigates the complex social hierarchy with calculated precision. Meanwhile, a mysterious implant expert detects Zhiyin’s Level Ten status and resolves to modify her personally. As Zhiyin rises in power under Shen Lianyan’s protection, she begins to reclaim her life, leaving behind the victimhood of her past and embracing her role as a formidable heir in a cybernetic world.
