Being a Salted Fish Second Generation in Various Worlds

Yu Qian, a transmigrator bound to a romance strategy system named 65, arrives in a new world with a mission to win the affection of a target named Zai Ye. Rejecting the exhausting conventional strategy of romantic pursuit, she utilizes a beginner gift package item called the Blood Relations Potion. Instead of using it on an existing body, she creates a two-year-old child form for herself and applies the potion, successfully transforming into the biological daughter of her target. The system, distressed by this unconventional approach, accompanies her as she navigates her new identity. Two years later, Yu Qian is found as a lost child at the Ningshui City Xinqiao Road Police Station. She possesses the memories of her mission but is heavily influenced by her toddler body, causing her adult consciousness to fade into simple desires for food, sleep, and comfort.

At the station, Zai Ye, a seventeen-year-old high school student known as a school bully, is brought in after a fight with his friends. He is distant from his parents due to their bitter divorce and his father's infidelity. When Yu Qian spots him, she immediately recognizes him as her mission target and clings to his leg, calling him "Daddy." The police officers, noting the striking resemblance between the child and the young man, pressure Zai Ye to take responsibility. Initially denying any relation, Zai Ye eventually claims she is his half-sister, the illegitimate daughter of his father, Zai Yan, to deflect the situation. He takes her to a local hangout called Soaring Lounge, where his friends Li Xiu and Wen Cheng are present.

At the lounge, the friends observe the uncanny physical similarities between Yu Qian and Zai Ye. Wen Cheng points out that her facial features resemble Zai Ye's mother, Wen Ling, rather than Zai Yan. This observation leads Li Xiu to arrange a confidential DNA test through his brother's testing center. The results shock everyone: Zai Ye is confirmed to be Yu Qian's biological father, not his father. Zai Ye is devastated and refuses to believe the results, demanding multiple retests at different facilities, all of which yield the same impossible conclusion. He is left grappling with the reality that he has a two-year-old daughter despite having no memory of a mother or any sexual encounter.

The secret does not remain hidden for long. Li Xiu accidentally shares photos of Yu Qian in a family group chat, which reaches Zai Ye's mother, Wen Ling. She and Zai Yan confront Zai Ye at his apartment. The reunion between the divorced parents is tense and hostile, filled with old grievances about their failed marriage and Zai Ye's upbringing. Zai Ye, feeling overwhelmed and unsupported, retreats to his room with Yu Qian, protecting her from their shouting. He asserts his independence, declaring that he will raise the child himself without their help, though he lacks the practical skills and resources to do so alone.

Zai Ye struggles to care for Yu Qian, facing challenges such as bathing her, feeding her, and finding suitable daycare. His attempts are clumsy and often result in mishaps, such as a cola incident that leads to Yu Qian crying and a failed attempt to style her hair. During a motorcycle ride with friends, Yu Qian gets dizzy and falls, leading to a fever that keeps her bedridden for days. The illness terrifies Zai Ye, who has never cared for a sick child before. He rushes her to the hospital multiple times, his anxiety evident. Eventually, he takes Yu Qian to his mother's villa, where Wen Ling steps in to teach him proper childcare techniques, from washing hair to selecting appropriate clothing and food.

As Zai Ye adjusts to his new role as a father, his relationship with his parents shifts. His mother moves back to Ningshui to be closer and offers to help, while his father provides financial support for Yu Qian's upbringing. Zai Ye begins to balance his school life with parenting duties, attending classes when possible and relying on his mother and friends for assistance. The story follows his gradual acceptance of fatherhood and the evolving dynamics within his fractured family as they navigate the unexpected arrival of a granddaughter who has bound them together.
