Shen Lang, a down-and-out man who was kidnapped by his ex-wife Lin Xuerou with the moral question "Are you worthy of being a father" and left home? However, he hid a secret in his heart - his daughter Shen Xiaomeng has a mysterious spiritual vein and is a rare genius in a thousand years. After the divorce, Lin Xuerou took her daughter to marry Zhao Zihao, a second-generation rich man, but she used her daughter as a tool to exploit her, just to pave the way for her stepson. Shen Lang endured the humiliation and finally awakened the golden finger [Father's Love Exchange System] on his daughter's fifth birthday: as long as he gives his sincerity and guidance to his daughter, he can unlock immortal magic, medical skills, business skills and other heaven-defying abilities. He originally wanted to quietly protect his daughter's growth, but his ex-wife's family pressed on her step by step, humiliating her in public, suppressing her from the company, and even using her daughter's commercial value to conduct live broadcasts to hype her up. Shen Lang no longer tolerated it, and used the "Kindergarten Parents' Meeting" as a battlefield. By teaching his daughter to recite ancient poems, draw talismans, and do small experiments, he crushed the elite education of the rich second generation and became an Internet celebrity overnight. Lin Xuerou was panicked and Zhao Zihao was angry. They discovered that the "waste" ex-husband who had been kicked out was using the power of the system to tear apart the lies they had carefully weaved. And their daughter Shen Xiaomeng, nourished by her father's love, burst out with amazing talents. A cool war about family love, revenge and the bottom line has officially begun.
